Abstract
Introduction The gut microbiota, T cell subsets, and cytokines participate in tuberculosis (TB) pathogenesis. To date, the mechanisms by which these factors interactively promote TB development at different time points remain largely unclear. In the context of this study, We looked into the microorganisms in the digestive tract, T cell types, and cytokines related to tuberculosis. Methods According to QIIME2, we analyzed 16SrDNA sequencing of the gut microbiome on the Illumina MiSeq. Enzyme-linked immunosorbent assay was used to measure the concentrations of cytokines. Results We showed the presence of 26 identifiable differential microbiomes in the gut and 44 metabolic pathways between healthy controls and the different time points in the development of TB in patients. Five bacterial genera (Bacteroides, Bifidobacterium, Faecalibacterium, Collinsella, and Clostridium) were most closely associated with CD4/CD8, whereas three bacterial taxa (Faecalibacterium, Collinsella, and Clostridium) were most closely associated with CD4. Three bacterial taxa (Faecalibacterium, Ruminococcus, and Dorea) were most closely associated with IL-4. Ruminococcus was most closely associated with IL-2 and IL-10. Conclusion Diverse microorganisms, subsets of T cells, and cytokines, exhibiting varying relative abundances and structural compositions, were observed in both healthy controls and patients throughout distinct phases of tuberculosis. Gaining insight into the function of the gut microbiome, T cell subsets, and cytokines may help modulate therapeutic strategies for TB.

Abstract
Metabolic dysfunction-associated steatotic liver disease(MASLD), formerly known as non-alcoholic fatty liver disease(NAFLD), has become a major cause of chronic liver disease and a significant risk factor for hepatocellular carcinoma, which poses a huge burden on global public health and economy. MASLD includes steatotic liver disease, steatohepatitis, and cirrhosis, and the latter two cause great harm to human health and life, even complicated with liver cancer. Immunologic mechanism plays a major role in promoting its development into hepatitis and cirrhosis. Now more and more evidences show that T cells play an important role in the progression of MASLD. In this review, we discuss the double roles of T cells in MASLD from the perspective of T cell response pathways, as well as new evidences regarding the possible application of immunomodulatory therapy in MASH.

Abstract
Objective Low molecular mass protein 7 (LMP7) aggravates abnormal T cell differentiation and atherosclerosis, but its clinical role in acute ischemic stroke (AIS) is still unclear. This study aimed to investigate the correlation of peripheral blood mononuclear cell (PBMC) LMP7 with T cell subsets, disease severity, and prognosis in AIS patients. Methods A total of 162 AIS patients were enrolled for detecting PBMC LMP7 and T helper (Th) 1, Th2, and Th17 cells via reverse transcriptase-polymerase chain reaction and flow cytometry, respectively. In addition, PBMC LMP7 at discharge was also quantified. Results Increased LMP7 at admission was associated with decreased Th2 cells (P=0.014), elevated Th17 cells (P<0.001), C-reactive protein (P=0.005), National Institutes of Health Stroke Scale (NIHSS) score (P=0.007), and disease severity (defined by NIHSS score) (P=0.010). LMP7 at admission reflected a high risk of stroke recurrence (area under curve (AUC): 0.748, 95% confidence interval (CI): 0.564-0.932), but not mRS score at month 3 (M3) >2 (AUC: 0.585, 95%CI: 0.479-0.691), or death (AUC: 0.723, 95%CI: 0.338-1.000). LMP7 at discharge was reduced compared to that at admission (P<0.001). LMP7 at discharge was positively correlated with the risk of stroke recurrence (AUC: 0.849, 95%CI: 0.735-0.963) and death (AUC: 0.919, 95%CI: 0.836-1.000), but had a weak capacity to reflect mRS score at M3 >2 (AUC: 0.671, 95%CI: 0.578-0.765). Conclusion PBMC LMP7 positively correlates with Th17 cells, inflammation, and disease severity in AIS patients, meanwhile, its level at discharge shows a good ability to reflect the risks of stroke recurrence and death.

Abstract
People who use drugs (PWUD) are at a high risk of contracting and developing severe coronavirus disease 2019 (COVID-19) and other infectious diseases due to their lifestyle, comorbidities, and the detrimental effects of opioids on cellular immunity. However, there is limited research on vaccine responses in PWUD, particularly regarding the role that T cells play in the immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). Here, we show that before vaccination, PWUD did not exhibit an increased frequency of preexisting cross-reactive T cells to SARS-CoV-2 and that, despite the inhibitory effects that opioids have on T-cell immunity, standard vaccination can elicit robust polyfunctional CD4+ and CD8+ T-cell responses that were similar to those found in controls. Our findings indicate that vaccination stimulates an effective immune response in PWUD and highlight targeted vaccination as an essential public health instrument for the control of COVID-19 and other infectious diseases in this group of high-risk patients.

Abstract
BACKGROUND Patients with immunodeficiencies commonly experience diagnostic delays resulting in morbidity. There is an unmet need to identify patients earlier, especially those with high risk for complications. Compared to immunoglobulin quantification and flowcytometric B cell subset analysis, expanded T cell subset analysis is rarely performed in the initial evaluation of patients with suspected immunodeficiency. The simultaneous interpretation of multiple immune variables, including lymphocyte subsets, is challenging. OBJECTIVE To evaluate the diagnostic value of cluster analyses of immune variables in patients with suspected immunodeficiency. METHODS Retrospective analysis of 38 immune system variables, including seven B cell and sixteen T cell subpopulations, in 107 adult patients (73 with immunodeficiency, 34 without) evaluated at a tertiary outpatient immunology clinic. Correlation analyses of individual variables, k-means cluster analysis with evaluation of the classification into "no immunodeficiency" versus "immunodeficiency" and visual analyses of hierarchical heatmaps were performed. RESULTS Binary classification of patients into groups with and without immunodeficiency was correct in 54% of cases with the full data set and increased to 69% and 75% of cases, respectively, when only 16 variables with moderate (p < .05) or 7 variables with strong evidence (p < .01) for a difference between groups were included. In a cluster heatmap with all patients but only moderately differing variables and a heatmap with only immunodeficient patients restricted to T cell variables alone, segregation of most patients with common variable immunodeficiency and combined immunodeficiency was observed. CONCLUSION Cluster analyses of immune variables, including detailed lymphocyte flowcytometry with T cell subpopulations, may support clinical decision making for suspected immunodeficiency in daily practice.

Abstract
AIMS Human umbilical cord mesenchymal stem cells (HUMSCs) have been documented to be effective for several immune disorders including inflammatory bowel diseases (IBD). However, it remains unclear how HUMSCs function in regulating immune responses and intestinal flora in the trinitrobenzene sulfonic acid (TNBS)-induced IBD model. MATERIALS AND METHODS We assessed the regulatory effects of HUMSCs on the gut microbiota, T lymphocyte subpopulations and related immune cytokines in the TNBS-induced IBD model. The mice were divided into the normal, TNBS, and HUMSC-treated groups. The effect of HUMSCs was evaluated by Hematoxylin and Eosin (H&E) staining, fluorescence-activated cell sorting (FACS), and enzyme-linked immunosorbent assay (ELISA) analyses. Metagenomics Illumina sequencing was conducted for fecal samples. KEY FINDINGS We demonstrated that the disease symptoms and pathological changes in the colon tissues of TNBS-induced colitis mice were dramatically ameliorated by HUMSCs, which improved the gut microbiota and rebalanced the immune system, increasing the abundance of healthy bacteria (such as Lactobacillus murinus and Lactobacillus johnsonii), the Firmicutes/Bacteroidetes ratio, and the proportion of Tregs; the Th1/Th17 ratio was decreased. Consistently, the expression levels of IFN-γ and IL-17 were significantly decreased, and transforming growth factor-β1 (TGF-β1) levels were significantly increased in the plasma of colitis mice HUMSC injection. SIGNIFICANCE Our experiment revealed that HUMSCs mitigate acute colitis by regulating the rebalance of Th1/Th17/Treg cells and related cytokines and remodeling the gut microbiota, providing potential future therapeutic targets in IBD.

Abstract
BACKGROUND Rapamycin (RAP), as a Mammalian Target of Rapamycin (mTOR) inhibitor, has a certain antiepileptic effect. The blood-brain barrier (BBB), neuroinflammation, lymphocyte immune cells, and neuronal apoptosis play an obligatory role in the course of a seizure. The aim of this study is to probe whether the antiepileptic mechanism of RAP involves the blood-brain barrier, neuroinflammation, lymphocytes, and neuronal apoptosis. METHODS First, we established a rat epilepsy model by injecting lithium chloride and pilocarpine into the rats (intraperitoneal injection). Then the epileptic rats were treated with different doses of RAP (1 mg/kg.d, 2 mg/kg.d, 4 mg/kg.d). Peripheral blood, brain tissue, and temporal lobe tissue were collected. The levels of blood-brain barrier-related proteins and inflammatory cytokines in the peripheral blood of rats were measured by enzyme-linked immunosorbent assay (ELISA). The effect of RAP on T cell subsets in epileptic rats was analyzed by flow cytometry. The apoptosis of neurons and glial cells in the temporal lobe of rats was analyzed by immunohistochemistry. RESULTS This study found that RAP reduces the levels of BBB-interrelated proteins (matrix metallopeptidase 9 (MMP-9), MMP-2, tissue inhibitor of metalloproteinases 1 (TIMP-1), TIMP-2) and inflammatory cytokines (interleukin-2 (IL-2), interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α)) in epileptic rats compared to the model group (p < 0.05). RAP increases the level of total T cells (CD3+CD45+) and T helper cells (CD3+CD4+), decreases the level of cytotoxic T lymphocytes (CD3+CD8+), and inhibits the apoptosis of neurons and glial cells in the temporal lobe compared to the model group (p < 0.05). CONCLUSIONS The antiepileptic mechanism of RAP may be to restore BBB dysfunction, reduce the inflammatory response, balance T cell subsets, and inhibit neuronal and glial cell apoptosis in temporal lobe epilepsy lesions.

Abstract
γδ T cells, a specialized subset of T lymphocytes, have garnered significant attention within the realm of cancer immunotherapy. Operating at the nexus between adaptive and innate immunological paradigms, these cells showcase a profound tumor discernment repertoire, hinting at novel immunotherapeutic strategies. Significantly, these cells possess the capability to directly identify and eliminate tumor cells without reliance on HLA-antigen presentation. Furthermore, γδ T cells have the faculty to present tumor antigens to αβ T cells, amplifying their anti-tumoral efficacy.Within the diverse and heterogeneous subpopulations of γδ T cells, distinct immune functionalities emerge, manifesting either anti-tumor or pro-tumor roles within the tumor microenvironment. Grasping and strategically harnessing these heterogeneous γδ T cell cohorts is pivotal to their integration in tumor-specific immunotherapeutic modalities. The aim of this review is to describe the heterogeneity of the γδ T cell lineage and the functional plasticity it generates in the treatment of malignant tumors. This review endeavors to elucidate the intricate heterogeneity inherent to the γδ T cell lineage, the consequential functional dynamics in combating malignancies, the latest advancements from clinical trials, and the evolving landscape of γδ T cell-based oncological interventions, while addressing the challenges impeding the field.

Abstract
Autosomal dominant polycystic kidney disease (ADPKD) has cancer-like pathophysiology. In this study, we aimed to investigate the phenotype of peripheral blood (PB) T cell subsets and immune checkpoint inhibitor expression of ADPKD patients across different chronic kidney disease (CKD) stages. Seventy-two patients with ADPKD and twenty-three healthy controls were included in the study. The patients were grouped into five different CKD stages, according to glomerular filtration rate (GFR). PB mononuclear cells were isolated and T cell subsets and cytokine production were examined by flow cytometry. CRP levels, height-adjusted total kidney volume (htTKV), rate of hypertension (HT) differed significantly across different GFR stages in ADPKD. T cell phenotyping revealed significantly elevated CD3+ T cells, CD4+, CD8+, double-negative, and double-positive subsets and significantly elevated IFN-γ and TNF-α producing subsets of CD4+, CD8+ cells. The expression of checkpoint inhibitors CTLA-4, PD-1, and TIGIT by T cell subsets was also increased to various extent. Additionally, Treg cell numbers and suppressive markers CTLA-4, PD-1, and TIGIT were significantly elevated in ADPKD patients' PB. Treg CTLA4 expression and CD4CD8DP T cell frequency in patients with HT were significantly higher. Lastly, HT and increased htTKV and higher frequency of PD1+ CD8SP were found to be risk factors for rapid disease progression. Our data provide the first detailed analyses of checkpoint inhibitor expression by PB T cell subsets during stages of ADPKD, and that a higher frequency of PD1+ CD8SP cells is associated with rapid disease progression.

Abstract
Currently, multiple studies have indicated that CD8+ T lymphocytes play a role in causing damage to the exocrine glands through acinar injury in primary Sjögren's syndrome (pSS). The aim of this research was to assess the imbalance of circulating CD8+ T cell subsets. We analyzed blood samples from 34 pSS patients and 34 healthy individuals as controls. We used flow cytometry to enumerate CD8+ T cell maturation stages, using as markers CD62L, CD28, CD27, CD4, CD8, CD3, CD45RA and CD45. For immunophenotyping of 'polarized' CD8+ T cell subsets, we used the following monoclonal antibodies: CXCR5, CCR6, CXCR3 and CCR4. The findings revealed that both the relative and absolute numbers of 'naïve' CD8+ T cells were higher in pSS patients compared to the healthy volunteers. Conversely, the proportions of effector memory CD8+ T cells were notably lower. Furthermore, our data suggested that among patients with pSS, the levels of cytotoxic Tc1 CD8+ T cells were reduced, while the frequencies of regulatory cytokine-producing Tc2 and Tc17 CD8+ T cells were significantly elevated. Simultaneously, the Tc1 cell subsets displayed a negative correlation with immunoglobulin G, rheumatoid factor, the Schirmer test and unstimulated saliva flow. On the other hand, the Tc2 cell subsets exhibited a positive correlation with these parameters. In summary, our study indicated that immune dysfunction within CD8+ T cells, including alterations in Tc1 cells, plays a significant role in the development of pSS.

Abstract
Patient-derived autologous chimeric antigen receptor (CAR)-T cell therapy is a revolutionary breakthrough in immunotherapy and has made impressive progress in both preclinical and clinical studies. However, autologous CAR-T cells still have notable drawbacks in clinical manufacture, such as long production time, variable cell potency and possible manufacturing failures. Allogeneic CAR-T cell therapy is significantly superior to autologous CAR-T cell therapy in these aspects. The use of allogeneic CAR-T cell therapy may provide simplified manufacturing process and allow the creation of 'off-the-shelf' products, facilitating the treatments of various types of tumors at less delivery time. Nevertheless, severe graft-versus-host disease (GvHD) or host-mediated allorejection may occur in the allogeneic setting, implying that addressing these two critical issues is urgent for the clinical application of allogeneic CAR-T cell therapy. In this review, we summarize the current approaches to overcome GvHD and host rejection, which empower allogeneic CAR-T cell therapy with a broader future.

Abstract
The thymus gland is a central lymphoid organ in which developing T cell precursors, known as thymocytes, undergo differentiation into distinct type of mature T cells, ultimately migrating to the periphery where they exert specialized effector functions and orchestrate the immune responses against tumor cells, pathogens and self-antigens. The mechanisms supporting intrathymic T cell differentiation are pleiotropically regulated by thymic peptide hormones and cytokines produced by stromal cells in the thymic microenvironment and developing thymocytes. Interestingly, in the same way as T cells, thymic hormones (herein exemplified by thymosin, thymulin and thymopoietin), can circulate to impact immune cells and other cellular components in the periphery. Evidence on how thymic function influences tumor cell biology and response of patients with cancer to therapies remains unsatisfactory, although there has been some improvement in the knowledge provided by recent studies. Herein, we summarize research progression in the field of thymus-mediated immunoendocrine control of cancer, providing insights into how manipulation of the thymic microenvironment can influence treatment outcomes, including clinical responses and adverse effects of therapies. We review data obtained from clinical and preclinical cancer research to evidence the complexity of immunoendocrine interactions underpinning anti-tumor immunity.

Abstract
INTRODUCTION The objective of the study was to determine T-cell subtypes, Natural Killer cell activity and cytokines in COVID-19 patients with mild to moderate disease and compare them between patients who had recovered and those who had progressed to severe disease. METHODS Peripheral blood samples of COVID-19 patients were collected at the time of hospital admission and after one week. These samples were analysed for interleukins (IL-6, IL-17a) using chemiluminescence ELISA. The T-cell subsets (T naïve, T regulatory, Th17, Th1, Th2, CD8+ T cells] were studied using flow cytometry. Mild, moderate and severe COVID-19 are defined as per CDC guidelines. RESULTS Nineteen COVID-19-positive patients were enrolled between June 2020 to December 2021. Nine had mild COVID-19 and 10 had moderate COVID-19 at recruitment. All mild cases recovered without progression to severe disease, while five patients from the moderate group progressed to severe disease. Overall, there is a decrease in lymphocyte count in patients with moderate-severe disease, but the ratio of Th17 [5.91 (2.69-12.01)] was higher compared to Th1 [1.12 (0.27-3.13)] and Th2[2.34 (2-3.5)]. The high baseline level of IL-6 observed in patients with moderate disease leads to the proliferation of more Th17 type of CD4+ T-cells(p=0.002) and suppression of Treg cells. A higher Th17 subset leads to neutrophilic inflammation in patients with severe COVID-19. CONCLUSION Interpretation conclusions: Higher baseline IL-6 leads to depletion of regulatory T-cells, Th1 Th2 CD4 cells. IL-6 leads to the proliferation of Th17 type of CD4+ subsets in moderate COVID-19. Higher Th17 cells in moderate COVID-19 patients lead to the production of IL-17a, which may result in intense neutrophilic inflammatory response and cytokine storm.

Abstract
Objective: To investigate the effects of combined blockade of interleukin-33 (IL-33) and inducible co-stimulatory molecule (ICOS) on carbon tetrachloride-induced chronic liver fibrosis and imbalance of T helper lymphocyte subsets in mice. Methods: There were 40 BALB/c mice in each model and control group. Flow cytometry was used to determine the proportion of Th1/Th2/Th17 cells in the splenic lymphocyte suspension of mice, the expression levels of interferon γ, IL-4, and IL-17 in the splenic lymphocyte suspension of liver fibrosis mice after combined blockade of IL-33 and ICOS, and the pathological changes of liver histopathology in mice with liver fibrosis. Two independent sample t-test was used to compare data between groups. Results: Compared with the non-blocking group, the proportion of Th2 and Th17 cells in the IL-33/ICOS blocking group was significantly down-regulated (Th2: 65.96% ± 6.04% vs. 49.09% ± 7.03%; Th17: 19.17% ± 4.03% vs. 9.56% ± 2.03%), while the proportion of Th1 cells and Th1/Th2 ratio were up-regulated (Th1: 17.14% ± 3.02% vs. 31.93% ± 5.02%; Th1/Th2: 0.28 ± 0.06 vs. 0.62 ± 0.23), and the difference was statistically significant (t = 5.15, 6.03, 7.14, 4.28, respectively, with P < 0.05). After entering the chronic inflammation stage of liver fibrosis in mice (10 weeks), compared with the non-blocking group, the expression levels of IL-4 and IL-17 in the blockade group were significantly down-regulated [IL-4: (84.75 ± 14.35) pg/ ml vs. (77.88 ± 19.61) pg/ml; IL-17: (72.38 ± 15.13) pg/ml vs. (36.38 ± 8.65) pg/ml], while the expression of interferon γ was up-regulated [(37.25 ± 11.51) pg/ml vs. (77.88 ± 19.61) pg/ml], and the difference was statistically significant (t: IL-4: 4.71; IL-17: 5.84; interferon γ: 5.05, respectively, with P < 0.05). Liver histopathological results showed that hepatic necrosis, hepatic lobular structural disorder, and fibrous tissue hyperplasia were significantly lower in the blockade group than those in the non-blocking group at 13 weeks of liver fibrosis. Conclusion: Combined blockade of the ICOS signaling pathway and IL-33 can regulate Th2 and Th17 polarization, down-regulate the inflammatory response, and inhibit or prevent the occurrence and progression of fibrosis.

Abstract
BACKGROUND Selective IgA deficiency (SIgAD) is the most prevalent inborn errors of immunity with almost unknown etiology. This study aimed to investigate the clinical diagnostic and prognostic values of lymphocyte subsets and function in symptomatic SIgAD patients. METHODS A total of 30 available SIgAD patients from the Iranian registry and 30 age-sex-matched healthy controls were included in the present study. We analyzed B and T cell peripheral subsets and T cell proliferation assay by flow cytometry in SIgAD patients with mild and severe clinical phenotypes. RESULTS Our results indicated a significant increase in naïve and transitional B cells and a strong decrease in marginal zone-like and switched memory B-cells in SIgAD patients. We found that naïve and central memory CD4+ T cell subsets, as well as Th1, Th2 and regulatory T cells, have significantly decreased. On the other hand, there was a significant reduction in central and effector memory CD8+ T cell subsets, whereas proportions of both (CD4+ and CD8+) terminally differentiated effector memory T cells (TEMRA) were significantly elevated in our patients. Although some T cell subsets in severe SIgAD were similar, a decrease in marginal-zone and switched memory B cells and an increase in CD21low B cell of severe SIgAD patients were slightly prominent. Moreover, the proliferation activity of CD4+ T cells was strongly impaired in SIgAD patients with a severe phenotype. CONCLUSION SIgAD patients have varied cellular and humoral deficiencies. Therefore, T cell and B cell assessment might help in better understanding the heterogeneous pathogenesis and prognosis estimation of the disease.

Abstract
This multiplex staining panel was developed to differentiate cattle T cells into conventional (CD4 and CD8) and unconventional (γδ-TCR) subsets as well as their stage of differentiation and activation. The combination of CD45RO and CD62L allows the identification of naïve (TNaïve ), central memory (TCM ), effector memory (TEM ) and terminal effector (TTE ) T cells. Activated cattle T cells (TAV ) can be identified by the cell surface expression of CD25. This panel was developed using cryopreserved cattle peripheral blood mononuclear cells (PBMCs) and tested on fresh as well as stimulated PBMCs. Therefore, this 8-color, 10-parameter flow cytometry panel simultaneously identifies cattle TNaïve , TAV , TCM , TEM , TTE and γδ-TCR cells. This panel will improve our ability to examine T-cell response to pathogens and vaccines in cattle including the potential to identify previously undescribed subpopulations. Furthermore, this panel can be readily optimized for other bovid species as many of these reagents are likely to cross react.

Abstract
The HIV-1 reservoirs harbor the latent proviruses that are integrated into the host genome. It is a challenging task to eradicate the proviruses in order to achieve an HIV cure. We have described a strategy for the clearance of HIV-1 infection through selective elimination of host cells harboring replication-competent HIV (SECH), by inhibition of autophagy and promotion of apoptosis during viral re-activation. HIV-1 can infect various CD4+ T cell subsets, but it is not known whether the SECH approach is equally effective in targeting HIV-1 reservoirs in these different subsets in vivo. In a humanized mouse model, we found that treatments of HIV-1 infection by suppressive antiretroviral therapy (ART) led to the establishment of latent HIV reservoirs in naïve, central memory and effector memory T cells. Moreover, SECH treatments could clear latent HIV-1 reservoirs in these different T cell subsets of humanized mice. Co-culture studies showed that T cell subsets latently infected by HIV-1, but not uninfected bystander cells, were susceptible to cell death induced by SECH treatments. Our study suggests that the SECH strategy is effective for specific targeting of latent HIV-1 reservoirs in different T cell subsets.

Abstract
Background Immunological phenotypes and differentiation statuses commonly decide the T cell function and anti-tumor ability. However, little is known about these alterations in CML patients. Method Here, we investigated the immunologic phenotypes (CD38/CD69/HLA-DR/CD28/CD57/BTLA/TIGIT/PD-1) of T subsets (TN, TCM, TEM, and TEMRA) in peripheral blood (PB) and bone marrow (BM) from de novo CML patients (DN-CML), patients who achieved a molecular response (MR) and those who failed to achieve an MR (TKI-F) after tyrosine kinase inhibitor (TKI) treatment using multicolor flow cytometry. Results CD38 or HLA-DR positive PB CD8+TN and TCM cells decreased in the DN-CML patients and this was further decreased in TKI-F patients. Meanwhile, the level of PD-1 elevated in CD8+ TEM and TEMRA cells from PB in all groups. Among BM sample, the level of HLA-DR+CD8+TCM cells significantly decreased in all groups and CD8+TEMRA cells from TKI-F patients exhibited increased level of TIGIT and CD8+ tissue-residual T cells (TRM) from DN-CML patients expressed a higher level of PD-1 and TIGIT. Lastly, we found a significantly decreased proportion of CD86+ dendritic cells (DCs) and an imbalanced CD80/CD86 in the PB and BM of DN-CML patients, which may impair the activation of T cells. Conclusion In summary, early differentiated TN and TCM cells from CML patients may remain in an inadequate activation state, particularly for TKI-F patients. And effector T cells (TEM, TEMRA and TRM) may be dysfunctional due to the expression of PD-1 and TIGIT in CML patients. Meanwhile, DCs cells exhibited the impairment of costimulatory molecule expression in DN-CML patients. Those factors may jointly contribute to the immune escape in CML patients.

Abstract
BACKGROUND The extent of immune reconstitution in human immunodeficiency virus (HIV) infected persons receiving long-term antiretroviral therapy (ART) with controlled viral load has been controversial. We studied the extent and speed of T cell subsets retrieval after long-term antiretroviral treatment. METHODS 662 HIV-infected patients followed at least 2 years whose plasma HIV-1 RNA load <50 copies/mL were evaluated for longitudinal and functional phenotypic indices of immune restoration. Determinants of change in magnitude and importance of recovery have been evaluated using mixed linear regression models. RESULTS Almost all robust immune restorations achieved occurred after 2-3 years of ART. The median CD4 lymphocyte count increased 449 cells/μl (IQR 303-604) from 226 cells/μl (IQR 83-336) at baseline during the third year (P < 0.001); CD4+T lymphocyte rises during the sixth and tenth years were not significant. Naive and memory CD4+T cells'reconstitution occurred in the sixth and eighth years of ART but no significant change thereafter. The change of CD45RA+Naïve and CD45RA-memory CD4+T cell reconstitution is different in baseline CD4+T cell counts <100 cells/μl group and in baseline CD4+T cell counts >100 cells/μl group. Activation antigen expression (CD38 or HLA-DR) on CD8 lymphocytes declined mostly during the first till second year, and after 4 years, activation antigen expression on patient lymphocytes showed no significant change. The proportion of CD4 cells expressing CD28 climbed during the first years and reached normal levels in the second year. CONCLUSIONS Immune restoration was dependent on the capacity of immune system during the first 2-3 year of ART. But the significant change of CD4 and compartments of CD4+T cells could persist until 6-8 years. The pattern of CD38+CD8+, HLA-DR+CD8+, CD28+CD4+ T cells could quickly return to normal level and no significant change after sufficient time of ART. In general, the immune response compared to the baseline status may be the overall effect from the age and time of antiretroviral treatment.

Abstract
BACKGROUND The pandemic coronavirus disease 2019 (COVID-19) is a major global public health concern and several protective vaccines, or preventive/therapeutic approaches have been developed. Sinovac-CoronaVac, an inactivated whole virus vaccine, can protect against severe COVID-19 disease and hospitalization, but less is known whether it elicits long-term T cell responses and provides prolonged protection. METHODS This is a longitudinal surveillance study of SARS-CoV-2 receptor binding domain (RBD)-specific IgG levels, neutralizing antibody levels (NAb), T cell subsets and activation, and memory B cells of 335 participants who received two doses of CoronaVac. SARS-CoV-2 RBD-specific IgG levels were measured by enzyme-linked immunosorbent assay (ELISA), while NAb were measured against two strains of SARS-CoV-2, the Wuhan and Delta variants. Activated T cells and subsets were identified by flow cytometry. Memory B and T cells were evaluated by enzyme-linked immune absorbent spot (ELISpot). FINDINGS Two doses of CoronaVac elicited serum anti-RBD antibody response, elevated B cells with NAb capacity and CD4+ T cell-, but not CD8+ T cell-responses. Among the CD4+ T cells, CoronaVac activated mainly Th2 (CD4+ T) cells. Serum antibody levels significantly declined three months after the second dose. INTERPRETATION CoronaVac mainly activated B cells but T cells, especially Th1 cells, were poorly activated. Activated T cells were mainly Th2 biased, demonstrating development of effector B cells but not long-lasting memory plasma cells. Taken together, these results suggest that protection with CoronaVac is short-lived and that a third booster dose of vaccine may improve protection.

Abstract
BACKGROUND AND AIM OF THE STUDY Systemic lupus erythematosus (SLE) is an autoimmune disease characterized by lymphocyte imbalance. The differentiation and function of T and B cells receive regulation from intracellular energy metabolism. Herein, we aimed to investigate glutamine metabolism levels in SLE and explore the effects of modulating glutamine metabolism on T and B cell subsets and related signaling pathways in MRL/lpr lupus mice. METHODS We assessed intracellular glutamine metabolism in SLE patients and MRL/lpr mice by measuring intracellular glutamate and Glutaminase 1 (GLS1) protein levels. Intraperitoneal injection of the GLS1 inhibitor CB839 was performed to reduce glutamine metabolism and lupus-like manifestations in MRL/lpr mice were evaluated. The proportions and numbers of T and B cell subsets were determinedvia flow cytometry. Pathway-related proteins were detected using western blotting. RESULTS In this study, we reported that glutamine metabolism levels were aberrantly elevated in splenic mononuclear cells from MRL/lpr lupus mice, as well as in peripheral blood mononuclear cells (PBMCs) of SLE patients. Inhibition of glutamine metabolism by CB839 treatment for 8 weeks alleviated the lupus-like manifestations in MRL/lpr mice, including the kidney lesions, urinary protein/creatinine ratio, spleen index, and serum IgG1. Meanwhile, CB839 treatment ameliorated the depletion of IL-10 producing B cells (B10) and adjusted the Th1/TH2 and TH17/Treg imbalance. The inhibition of GLS1 by CB839 reduced the numbers of follicular helper T (TfH) cells and activated B cells in lupus mice. The proportions of mature B cells and plasma cells were not affected. Furthermore, the hyperactivated mTOR/P70S6K/4EBP1 and NLRP3/caspase-1/IL-1β pathways in MRL/lpr mice were reversed by CB839 treatment. CONCLUSION Our study confirmed the presence of abnormal intracellular glutamine metabolism in SLE and revealed potential therapeutic targets for this disease.

Abstract
Dissecting cellulitis of the scalp (DCS) is a rare skin disease and understudied. The aim of the study was to collect the demographic, clinical features and laboratory tests of patients with DCS in a dermatology outpatient clinic. A cross-sectional study was conducted in a department of dermatology in Beijing. Patients whose diagnoses have included DCS were selected from July 2021 to December 2021. DCS patients were stratified according to whether they were follicular occlusion triad (FOT) or not. There were 169 patients with DCS included. All 169 patients were male, and the median patient age was 32 years. The most common comorbidities in this study were seborrheic dermatitis (10.65%). Over 1/3 of patients had elevated white blood cell (WBC) and neutrophil counts, and 12 of 18 patients had dyslipidemia. CD8+ T cell counts increased in 15 of 26 patients while CD4+ T/CD8+ T ratios were all normal. DCS mainly affects men in their thirties. More research about DCS is needed to clarify the clinical significance of laboratory tests.

Abstract
The function of germinal centers (GCs) is an important factor in the pathogenesis of immunoglobulin G4 (IgG4)-related disease, in which inflammatory and fibrotic processes are controlled by type 2 helper T (Th) cells and regulatory T cells. T follicular helper cells (Tfh), which are present in GCs, regulate GC development, and they consist of Tfh1, Tfh2, and Tfh17 subsets. This study examined the association of Th cell subsets in IgG4-RD and pathogenesis of the disease using whole-slide image analysis for immunohistochemistry. IgG4-related sclerosing sialadenitis (IgG4-SS, n = 19) was characterized by higher numbers of Tfh2 and Tfh17 cells than Tfh1 cells compared to the findings in patients with chronic sialadenitis (n = 18) or Sjögren syndrome (n = 17). The number of Tfh2 cells was significantly associated with all parameters of GC structures and the number of IgG4 + plasmacytes, whereas the number of Tfh1 cells was inversely associated with the aforementioned parameters. Concerning extrafollicular helper T (Teh) cells, among three groups, the Tfh2/Teh2 ratio was highest and the Tfh1/Teh1 ratio was lowest in the IgG4-SS group, which exhibited a characteristically regional distribution of Tfh and Teh subsets, especially higher numbers of Teh2 cells and lower numbers of Teh1 cells in the mantle areas surrounding GCs. Mantle Teh2 cells and central Tfh17 cells were significantly correlated with morphological abnormalities of GCs. Our results indicated that the peculiar regional distribution and altered balance of Tfh and Teh subsets are novel hallmarks of IgG4-SS that are associated with GC formation in IgG4-SS.

Abstract
Infiltration of immunosuppressive cells in the tumor microenvironment (TME) induced colorectal cancer (CRC) progression and its resistance to immunotherapy. Identification of tumor-specific factors to modulate inhibitory immunocyte infiltration would provide alternative and novel targets for CRC immunotherapy. Immunoglobulin-like transcript (ILT) 5 is a negative regulator of myeloid cell activation. However, its expression and functional role in solid tumors is still unknown. Using human CRC tissues and cell lines, we found that ILT5 was highly expressed in CRC cells compared with normal colorectal epithelial cells. Enriched ILT5 in tumor cells was correlated with advanced tumor stages and poor patient survival. Our subsequent in vitro and in vivo studies revealed that tumor-derived ILT5 inhibited the infiltration of T cells, especially that of CD8+ T cells in the TME, creating suppressive T-cell contexture. Furthermore, ILT5 directed M2-like polarization of tumor-associated macrophages (TAMs). Inhibition of tumor-derived ILT5 restored the immunosuppressive T-cell and TAM contexture, and restricted CRC progression. Our findings identified ILT5 expression in solid tumor cells for the first time and raised ILT5 as a potential immunotarget and prognostic predictor in CRC.

Abstract
The role of T cells in the control of SARS-CoV-2 infection has been underestimated in favor of neutralizing antibodies. However, cellular immunity is essential for long-term viral control and protection from disease severity. To understand T-cell immunity in the absence of antibody generation we focused on a group of SARS-CoV-2 Non-Seroconvertors (NSC) recovered from infection. We performed an immune comparative analysis of SARS-CoV-2 infected individuals stratified by the absence or presence of seroconversion and disease severity. We report high levels of total naïve and low effector CD8+ T cells in NSC. Moreover, reduced levels of T-cell activation monitored by PD-1 and activation-induced markers were observed in the context of functional SARS-CoV-2 T-cell responses. Longitudinal data indicate the stability of the NSC phenotype over three months of follow-up after infection. Together, these data characterized distinctive immunological traits in NSC including skewed cellular distribution, low activation and functional SARS-CoV-2 T-cell responses. This data highlights the value of T-cell immune monitoring in populations with low seroconversion rates in response to SARS-CoV-2 infection and vaccination.

Abstract
Transforming growth factor-β (TGF-β) is a multifunctional regulatory cytokine that maintains tolerance in the immune system by regulating the proliferation, differentiation and survival of lymphocytes. TGF-β blockade therapy for cancer has achieved some results but shows limited efficacy and side effects because these drugs are not selective and act on various types of cells throughout the body. We demonstrate here that dominant negative TGF-β receptor type II specifically targeting T cells decreases tumor load in tumor-bearing mice. In addition, the dominant negative TGF-β receptor type II promotes the proliferation and differentiation of T cells and increases the expression of T-bet, which in turn promotes the secretion of granzyme A, granzyme B, perforin and IFN-γ secreted by T cells, and enhances the cytotoxicity and anti-tumor effects of T cells. Moreover, we also found that dominant negative TGF-β receptor type II reduces the proportion of regulatory T cells (Tregs) in tumor tissue and spleen of tumor-bearing mice. Co-culture experiments with T cells and tumor cells revealed that dominant negative TGF-β receptor type II inhibited tumor cell proliferation and increased apoptosis. Our results indicate that specifically inhibiting TGF-β receptor type II in T cells increases anti-tumor immunity and has a strong therapeutic potential.

Abstract
Colorectal cancer (CRC) is the third most common malignancy. Its development and progression is associated with natural immunosuppression related, among others, to myeloid derived suppressor cells (MDSCs). Overall, 54 patients in different stage of CRC, before any treatment were recruited into the study. The analysis included flow cytometry evaluation of blood MDSCs subsets, correlation their level with the tumor stage and T cell subsets. In the case of 11 patients, MDSCs level was evaluated before and 3 days after surgery, and these patients were monitored for cancer recurrence over 5 years. The results showed that frequency of circulating MDSCs subsets is increased significantly in CRC patients, with highest level detected in most advanced tumor stages. Moreover, only monocytic MDSCs (Mo-MDSCs) positively correlate with regulatory Treg, and negatively with tumor Her2/neu specific CD8+ T cells. Circulating MDSCs, in contrast to tumor resident (mostly Mo-MDSCs), are negative for PD-L1 expression. Additionally, after surgery the blood level of Mo-MDSCs increases significantly, and this is associated with tumor recurrence during a 5-year follow-up. In conclusion, Mo-MDSCs are pivotal players in CRC-related immunosuppression and may be associated with the risk of tumor recurrence after surgery.

Abstract
Blood was collected from the New York State Department of Health (NYSDOH) employees to assess variances in leukocyte numbers in January, May, and September throughout a year and over many years. Women and men of ages 20 to 80 volunteered to donate for this program. Most of the blood came from healthy individuals, and many remained healthy throughout the years of their blood donations. The major objective was to determine the extent that blood leukocyte numbers change so that transient vs more lingering changes may be helpful in assessing health status. Since some donors remained in the program for 14 years, age influences over time could be determined. Within a short period of 2-3 years, the flow cytometric immunophenotypic profile of blood lymphocyte is relatively stable with a CV% of < 20%. However, as humans age, the blood CD3+ T cell, CD8+ T cell, B cell, NKT cell, and CD4-/CD8- double-negative T cell (DN-T cell) subsets declined in cell numbers/μL, but the double-positive CD4+/CD8+ T cells (DP-T cells) increased in numbers. The extent and chronology of a variance, e.g., a subset exceeding its 75th or 90th percentile, might be indicative of a transient or chronic physiological or psychosocial stress affecting health or a developing pathology; however, because of the wide ranges of cell numbers/μL for each subset among individuals reported as healthy, everyone's immunity and health must be carefully evaluated. A CD4 to CD8 ratio (4/8R) of < 1 has been used to define an immunodeficiency such as HIV-induced AIDS, but a high 4/8R is less well associated with health status. A high 4/8R or granulocyte to lymphocyte ratio (GLR) might be an indicator of a stress, infection, or immune-related pathology. Sporadic and longitudinal increases of GLRs are reported. The results suggest that there are some age and sex differences in leukocyte numbers; stress influences on the blood profile of leukocytes likely exist. However, some values exceeding 2 standard deviations from means do not necessarily predict a health concern, whereas a longitudinal increase or decline might be indicative of a need for further evaluations.

Abstract
This study evaluated the in vitro modulatory effect of vitamin D (VD) on T cells, by determining the expression of STATs and the transcription factors of each CD4+ T cell subsets. Twenty women with preeclampsia (PE) and 20 normotensive pregnant women were studied. Peripheral blood mononuclear cells were cultured with or without VD to analyse the STATs and transcription factors by flow cytometry, and cytokines production by ELISA. The plasma levels of VD were lower in the PE group. Treatment of cells with VD decreased STAT1/STAT4/T-bet, STAT3/RORγt, and increased STAT6/GATA-3 and STAT5/FoxP3 in preeclamptic women. Treatment with VD also decreased the levels of inflammatory cytokines and increased IL-10 and TGF-β. This hormone exerts immunomodulatory effects on the STAT signalling pathway, shifting the inflammatory profiles, Th1/Th17 cells to Th2/Treg profiles, and it can be suggested as a promising strategy to regulate the systemic inflammatory response in PE.

Abstract
T helper cells, especially Th1 and Th17 cells, were reported to play a pivotal role in the pathogenesis of inflammatory bowel disease (IBD). However, the underlying factors regulating T cell functions in IBD progression remain to be fully elucidated. Here, we revealed that IL-17RD/Sef exacerbates DSS-induced colitis by regulating the balance of T cell subsets and their secretion of associated cytokines. We also observed that IL-17RD/Sef promotes colitis-associated tumorigenesis and negatively correlates with survival in both mouse and colorectal cancer patients. Our results suggested that IL-17RD/Sef functions as a regulator of T cell subsets to promote the inflammatory responses in the pathogenesis of IBD and colitis-associated colon cancer.

Abstract
Purpose Immune checkpoint blockade (ICB) therapy shows little or no clinical benefit in most colorectal cancer (CRC) patients, due to the immunosuppressive T cell contexture in the tumor microenvironment (TME). Immunoglobulin-like transcript (ILT) 4 is an immunosuppressive molecule in myeloid cells. ILT4 is enriched in solid tumor cells, facilitating their proliferation, invasion, and metastasis. However, the regulatory role of ILT4 in T cell immunity of CRC is still undetermined. Here, we aimed to explore how tumor cell-derived ILT4 orchestrates T cell infiltration, subset distribution, and function in CRC. Methods A total of 145 paraffin-embedded cancer tissues and the corresponding clinicopathological information were collected from CRC patients. Immunohistochemical (IHC) staining and public database analyses determined the correlation of ILT4 expression with different T cell subset densities, IFN-γ levels, and patient outcomes. Paired Ig-like receptor B (PIR-B, ILT4 mouse ortholog)-overexpressing/-downregulated MC38 cells were subcutaneously injected into C57BL/6 mice as a CRC transplantation model. The frequencies, subsets, and IFN-γ levels of T cells in mouse blood and spleens were determined using flow cytometry and immunohistochemistry, respectively. Results High ILT4 expression in CRC cells was associated with decreased T cell infiltration, disease progression, and poor patient survival. T cell subset analyses indicated that ILT4-high patients showed reduced CD8+ T cell but elevated FOXP3+ regulatory T (Treg) cell frequencies in the TME. High ILT4 levels predicted lower IFN-γ production by tumor-infiltrating lymphocytes (TILs), especially by CD8+T cells in human CRC tissues. Moreover, PIR-B overexpression accelerated MC38 growth in mice, decreased CD3+/CD8+/IFN-γ+ T cell densities, and elevated Treg infiltration in the TME, blood, and spleens. PIR-B knockdown had the opposite effects. Conclusion ILT4 in CRC cells induced immunosuppressive T cell subset infiltration and impaired IFN-γ production in TILs, suggesting that ILT4 might be a potential immunotherapeutic target and prognostic biomarker.

Abstract
OBJECTIVES CD4+CD8+ double-positive (DP) T cells are expanded in the peripheral blood of a subset of patients with rheumatoid arthritis (RA). This study examines the clinical significance of DP T cells in RA. METHODS In 70 RA patients, DP T cells were measured by flow cytometry. Clinical data were obtained, and hand and feet radiographs were scored according to the Sharp/van der Heijde (SvdH) method. The association between DP T cell frequency and erosive joint destruction was analyzed by correlation and multiple logistic regression analysis. RESULTS Nineteen RA patients (27.1%) displayed increased DP T cell frequencies, which correlated with age (r = 0.288, p= 0.016). Expansion of DP T cells was associated with the occurrence of erosions (94,7% vs 43,1%, p< 0.001), with a higher SvdH joint damage score (24.5 vs 6, p= 0.008) and with more frequent use of biologic or targeted-synthetic DMARDs (68.4% vs 38%, p= 0.02). In patients with non-erosive disease, DP T cell frequencies correlated with the joint space narrowing score (n = 28, r = 0.44, p= 0.02). Logistic regression revealed DP T cells to be associated with erosive disease (OR 1.90, p< 0.05). CONCLUSION Expansion of DP T cells is associated with joint damage and frequent escalation of therapy, possibly suggesting a contribution to more severe RA.

Abstract
Numerous studies have investigated the beneficial effects of Lactobacillus johnsonii strain BS15 on mice and broilers. This study aimed to understand the growth-promoting effects of BS15 on piglets. We determined the effects of L. johnsonii BS15 and a commercial probiotic strain, Bacillus subtilis JS01. Seventy-two suckling piglets (1 ± 2-day-old) were divided into three groups and fed with diets supplemented with 1 × 106 colony-forming units (cfu) BS15 per gram of feed (BS15 group); 1 × 106 cfu JS01 per gram of feed (JS01 group); or de Man, Rogosa, and Sharpe liquid medium (control group) 35 days. Compared with JS01, BS15 significantly improved the daily weight gain and diarrhea index of the piglets. The BS15 group had higher fecal sIgA levels, whereas the JS01 group had high fecal sIgA levels only after 35 days of treatment. Additionally, BS15 altered T cell subsets in peripheral blood by significantly increasing the CD3+CD4+ T cell percentage and CD3+CD4+/CD3+CD8+ ratio and decreasing the CD3+CD8+ T cell percentage. Moreover, BS15 exerted better beneficial effects on fecal microbiota than JS01. Specifically, the BS15 group had markedly increased Clostridium, Peptococcus, and Lactobacillus populations on days 7 and 21 of treatment and reduced Escherichia coli populations on day 35 of treatment. These findings indicated that BS15 can be applied as a probiotic that promotes growth performance and controls diarrhea in piglets.

Abstract
Background This study aimed to establish machine learning models for preoperative prediction of the pathological types of acute appendicitis. Methods Based on histopathology, 136 patients with acute appendicitis were included and divided into three types: acute simple appendicitis (SA, n=8), acute purulent appendicitis (PA, n=104), and acute gangrenous or perforated appendicitis (GPA, n=24). Patients with SA/PA and PA/GPA were divided into training (70%) and testing (30%) sets. Statistically significant features (P<0.05) for pathology prediction were selected by univariate analysis. According to clinical and laboratory data, machine learning logistic regression (LR) models were built. Area under receiver operating characteristic curve (AUC) was used for model assessment. Results Nausea and vomiting, abdominal pain time, neutrophils (NE), CD4+ T cell, helper T cell, B lymphocyte, natural killer (NK) cell counts, and CD4+/CD8+ ratio were selected features for the SA/PA group (P<0.05). Nausea and vomiting, abdominal pain time, the highest temperature, CD8+ T cell, procalcitonin (PCT), and C-reactive protein (CRP) were selected features for the PA/GPA group (P<0.05). By using LR models, the blood markers can distinguish SA and PA (training AUC =0.904, testing AUC =0.910). To introduce additional clinical features, the AUC for the testing set increased to 0.926. In the PA/GPA prediction model, AUC with blood biomarkers was 0.834 for the training and 0.821 for the testing set. Combining with clinical features, the AUC for the testing set increased to 0.854. Conclusions Peripheral blood biomarkers can predict the pathological type of SA from PA and GPA. Introducing clinical symptoms could further improve the prediction performance.

Abstract
In agreement with other fungal infections, immunoprotection in pulmonary paracoccidioidomycosis (PCM) is mediated by Th1/Th17 cells whereas disease progression by prevalent Th2/Th9 immunity. Treg cells play a dual role, suppressing immunity but also controlling excessive tissue inflammation. Our recent studies have demonstrated that the enzyme indoleamine 2,3 dioxygenase (IDO) and the transcription factor aryl hydrocarbon receptor (AhR) play an important role in the immunoregulation of PCM. To further evaluate the immunomodulatory activity of AhR in this fungal infection, Paracoccidioides brasiliensis infected mice were treated with two different AhR agonists, L-Kynurenin (L-Kyn) or 6-formylindole [3,2-b] carbazole (FICZ), and one AhR specific antagonist (CH223191). The disease severity and immune response of treated and untreated mice were assessed 96 hours and 2 weeks after infection. Some similar effects on host response were shared by FICZ and L-Kyn, such as the reduced fungal loads, decreased numbers of CD11c+ lung myeloid cells expressing activation markers (IA, CD40, CD80, CD86), and early increased expression of IDO and AhR. In contrast, the AhR antagonist CH223191 induced increased fungal loads, increased number of pulmonary CD11c+ leukocytes expressing activation markers, and a reduction in AhR and IDO production. While FICZ treatment promoted large increases in ILC3, L-Kyn and CH223191 significantly reduced this cell population. Each of these AhR ligands induced a characteristic adaptive immunity. The large expansion of FICZ-induced myeloid, lymphoid, and plasmacytoid dendritic cells (DCs) led to the increased expansion of all CD4+ T cell subpopulations (Th1, Th2, Th17, Th22, and Treg), but with a clear predominance of Th17 and Th22 subsets. On the other hand, L-Kyn, that preferentially activated plasmacytoid DCs, reduced Th1/Th22 development but caused a robust expansion of Treg cells. The AhR antagonist CH223191 induced a preferential expansion of myeloid DCs, reduced the number of Th1, Th22, and Treg cells, but increased Th17 differentiation. In conclusion, the present study showed that the pathogen loads and the immune response in pulmonary PCM can be modulated by AhR ligands. However, further studies are needed to define the possible use of these compounds as adjuvant therapy for this fungal infection.

Abstract
OBJECTIVE To explore the effect of acupuncture combined with Shenqi Yigan Decoction on liver function and T cell subsets in patients with Hepatitis B virus-induced liver fibrosis. METHODS All of the 90 patients with HBV-induced liver fibrosis were divided into two groups with the control group (n=45) treated with the conventional treatment, and the observation group (n=45) treated with acupuncture and Shenqi Yigan decoction based on the observation group. The seroconversion rate of hepatitis Be antigen (HBeAg), the liver function, the serum indexes of liver fibrosis of hyaluronic acid (HA), laminin (LN), type III procollagen (PC III), type IV collagen (IV-C), the T cell subsets and the inflammatory factors were compared between the two groups. RESULTS After 2 and 4 months of treatment, the HBeAg seroconversion rate of patients in the observation group was higher than that of the control group, but the difference was not significant (P>0.05). And the HBeAg seroconversion rate of patients in the observation group was significantly higher than that of the control group after 6 months treatment (P<0.05). After treatment, the serum levels of the liver function index of aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin (Tbil), the liver fibrosis index of HA, LN, PC III, and the inflammatory factor of type IV collagen (IV-C), C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) in the two groups were lower than those before treatment, in addition, the levels of there index were lower in the observation group (all P<0.05). After treatment, the proportion of CD3+, CD4+ T lymphocyte subsets and CD4+/CD8+ in peripheral blood of the two groups were increased, and the proportion of CD8+ was decreased. The change range of the observation group was larger than that of the observation group (all P<0.01). The proportion of patients with liver fibrosis grade F1 in the observation group after treatment was significantly higher than that before treatment, and the proportion of patients with liver fibrosis grade F2 to F3 was significantly lower than that before treatment. There was a significant difference in liver fibrosis grade between the two groups after treatment (P<0.05). CONCLUSION The combined treatment of acupuncture and Shenqi Yigan decoction can significantly improve the liver function of patients with HBV-induced liver fibrosis, delay the progress of liver fibrosis, improve the cellular immune function and reduce the inflammatory reaction.

Abstract
Kaposi's sarcoma (KS) is a malignancy of vascular origin. It is caused by the Kaposi's sarcoma-associated herpes virus (KSHV). Immune dysregulation is a key feature in the development and progression of KS. The main aim of this study was to determine and compare circulating CD4+ and CD8+T cell subsets including their expression of CD40 ligand (CD40L) and programmed cell death protein 1 (PD1), natural killer (NK) cells, and NK T cells between individuals with active HIV-associated KS versus those in remission. We found that the proportion of CD4+T cells was significantly higher in individuals in remission compared to those with active KS (26.3% vs 13.9%; p = 0.01). We also observed that the proportion of CD4+T cells and central memory CD4+T cells expressing CD40L was significantly higher in individuals with active KS versus those in remission, (10.6% vs 5.4%; p = 0.03) and (14.8% vs 5.9%; p = 0.01) respectively. There was no significant difference in proportion of CD4+ and CD8+ naïve, central memory, effector memory, and terminal effector cells between the two groups. In addition, there was no difference in expression of PD1 on the T cell subsets between the two groups. Furthermore, the proportion of NK cells and NK T cells were not differential between individuals with active disease versus those in remission. CD40L expression is higher in individuals with active HIV-associated KS compared to those in remission. The proportion of CD4+T cells is higher in individuals in remission compared to those with active HIV-associated KS.

Abstract
AIM To characterize immune suppression in lymphoma, thymocyte selection-associated high mobility group box protein (TOX) expression and co-expression with programmed cell death receptor-1 (PD-1), T cell immunoglobulin mucin-domain-containing-3 (Tim-3), and CD244 in CD3+, CD4+, CD8+, and regulatory T (Treg) cells from patients with lymphomas were analyzed. METHODS TOX expression and co-expression with PD-1, Tim-3, and CD244 in CD3+, CD4+, Treg, and CD8+ T cells were analyzed by multi-color fluorescent flow cytometry using peripheral blood (PB) from 13 newly diagnosed, untreated lymphoma patients, and 11 healthy individuals. RESULTS An increased percentage of TOX+ CD3+, CD4+, and CD8+ T cells was found in PB from patients with B cell non-Hodgkin's lymphoma (B-NHL) in comparison with healthy controls. Moreover, TOX+PD-1+ and TOX+Tim-3+ double-positive T cells increased among the CD3+, CD4+, and CD8+T cell populations in the B-NHL group. There was apparent heterogeneity in TOX expression and co-expression with PD-1, Tim-3, and CD244 in CD3+, CD4+, and CD8+ T cells in different lymphoma patients. In addition, the percentage of CD4+CD25+FoxP3+ T cells (Treg) among the CD3+ and CD4+ T cells significantly increased, and the number of TOX+ and TOX+PD-1+ Treg cells also significantly increased in the B-NHL group. CONCLUSIONS Higher expression of TOX concurrent with PD-1, Tim-3, and CD244 in T cells from patients with B-NHL may contribute to T cell exhaustion and impair their special anti-tumor T cell activity. TOX may be considered a potential target for reversing T cell exhaustion and improving T cell function in hematological malignancies.

Abstract
Through considerable effort in research and clinical studies, the immune system has been identified as a participant in the onset and progression of brain injury after ischaemic stroke. Due to the involvement of all types of immune cells, the roles of the immune system in stroke pathology and associated effects are complicated. Past research concentrated on the functions of monocytes and neutrophils in the pathogenesis of ischaemic stroke and tried to demonstrate the mechanisms of tissue injury and protection involving these immune cells. Within the past several years, an increasing number of studies have elucidated the vital functions of T cells in the innate and adaptive immune responses in both the acute and chronic phases of ischaemic stroke. Recently, the phenotypes of T cells with proinflammatory or anti-inflammatory function have been demonstrated in detail. T cells with distinctive phenotypes can also influence cerebral inflammation through various pathways, such as regulating the immune response, interacting with brain-resident immune cells and modulating neurogenesis and angiogenesis during different phases following stroke. In view of the limited treatment options available following stroke other than tissue plasminogen activator therapy, understanding the function of immune responses, especially T cell responses, in the post-stroke recovery period can provide a new therapeutic direction. Here, we discuss the different functions and temporal evolution of T cells with different phenotypes during the acute and chronic phases of ischaemic stroke. We suggest that modulating the balance between the proinflammatory and anti-inflammatory functions of T cells with distinct phenotypes may become a potential therapeutic approach that reduces the mortality and improves the functional outcomes and prognosis of patients suffering from ischaemic stroke.

Abstract
Adoptive T cell therapy (ACT) holds great promise for cancer treatment. One approach, which has regained wide interest in recent years, employs antitumor T cells isolated from tumor lesions ("tumor-infiltrating lymphocytes" or TIL). It is now appreciated that a considerable proportion of anti-melanoma TIL recognize new HLA-binding peptides resulting from somatic mutations, which occurred during tumor progression. The clinical efficacy of TIL can potentially be improved via their genetic modification, designed to enhance their survival, homing capacity, resistance to suppression, tumor killing ability and additional properties of clinical relevance. Successful implementation of such gene-based strategies critically depends on efficient and reproducible protocols for gene delivery into clinical TIL preparations. Here we describe an optimized protocol for the retroviral transduction of TIL. As the experimental system we employed anti-melanoma TIL cultures prepared from four patients, recombinant retrovirus encoding an anti-CD19 chimeric antigen receptor (CAR) as a model gene of interest and CD19+ and CD19- human cell lines serving as target cells. Transduction on day 7 of the rapid expansion protocol (REP) resulted in 69 ± 8% CAR positive TIL. Transduced, but not untransduced TIL, from the four patients responded robustly to CD19+, but not CD19- cell lines, as judged by substantial secretion of IFN-γ following co-culture. In light of the rekindled interest in antitumor TIL, this protocol can be incorporated into a broad range of gene-based approaches for improving the in-vivo survival and functionality of TIL in the clinical setting.

Abstract
BACKGROUND T lymphocyte are a strong indicator of treatment immune response. This study was aimed to determine the utility of T lymphocyte subsets, cytokines and inflammatory biomarkers in predicting the immunological benefits of Ganoderma spore powder (G. lucidum) in post-operative patients with breast and lung cancer. METHODS We prospectively evaluated 120 breast and lung cancer patients with or without G. lucidum. T lymphocyte subsets with relative cytokines were detected using flow cytometry and PCR and assessed by Spearman correlation analysis. The relationships between albumin-to-globulin ratio (AGR) and neutrophil-to-lymphocyte ratio (NLR) with G. lucidum treatment and prognosis were analyzed using Kaplan-Meier and Cox regression methods. RESULTS The prevalence of CD3 + CD4 + , CD3 + HLADR- types was higher in G. lucidum group compared to control, whilst CD4 + CD25 + Treg, CD3 + HLADR + cell types was lower. IL-12 levels were significantly higher during the treatment period which negatively impacted levels of IL-10. Other immunosuppressive factors such as COX2 and TGF-β1 had lower prevalence in treated patients. Correlation analysis showed a positive relationship between IL-10 and CD28. IL-2 was positively related to TGF-β1, whilst it was negatively related to CD3. Kaplan-Meier analysis suggested that low AGR/high NLR was related to poor progression free survival (PFS) and overall survival (OS). A combination of high AGR and low NLR may predicted treatment benefits associated with PFS and OS. CONCLUSIONS Our findings show that T lymphocyte subsets combined with relevant cytokines and AGR/NLR inflammatory predictors may help to identify patients most likely to benefit from the immunological enhancements from G. lucidum treatment.

Abstract
Tumor metastases to regional lymph nodes are associated with worse outcome for patients with resected non-small cell lung cancer (NSCLC), but there is a wide variation in survival. We hypothesized that infiltration of tumor-involved lymph nodes with activated effector T cells would impact subsequent outcome. A total of 54 lymph nodes (27 N+ and 15 N- collected from 12 patients with Stage IIB (T2N1M0) and 12 N- lymph nodes collected from 10 patients with Stage IIA (T2N0M0) who underwent lymphadenectomy during surgical management of their NSCLC) were analyzed for effector T cells expressing activation markers PD-1 and TIM-3 using the Opal-multiple immunofluorescence assay. The frequency of CD3+CD8+ (P=0.0001), CD3+CD8+TIM-3+ (P<0.0001), and CD3+CD8+TIM-3+Ki-67+ (P<0.0001) T cells was greater in lymph nodes of IIA patients compared with IIB patients; however the frequency of CD3+CD8+PD-1+ (P=0.0086), CD3+CD8+TIM-3+ (P=0.0129), CD3+CD8+PD-1+Ki-67+ (P<0.0001) and CD3+CD8+TIM-3+Ki-67+ (P=0.0001) T cells was greater among the tumor involved (N+) nodes of N1 patients compared with the tumor-uninvolved (N-) nodes. The frequency of intranodal CD3+CD8+, CD3+CD8+PD-1+ and CD3+CD8+PD-1+Ki-67+ T cells in N+ nodes was associated with prolonged progression-free (PFS) and overall survival (OS). These data suggest that CD3+CD8+TIM-3+ T cells may suppress tumor spread to regional lymph nodes but once tumor cells metastasize to lymph nodes, CD3+/CD8+/PD-1+/Ki67+ T cells localizing to N+ nodes may prevent further tumor spread, resulting in prolonged survival.

Abstract
Sjogren´s syndrome (SS) is an autoimmune disease whose pathogenesis is characterized by an exacerbated T cell infiltration in exocrine glands, markedly associated to the inflammatory and detrimental features as well as the disease progression. Several helper T cell subsets sequentially converge at different stages of the ailment, becoming involved in specific pathologic roles. Initially, their activated phenotype endows them with high migratory properties and increased pro-inflammatory cytokine secretion in target tissues. Later, the accumulation of immunomodulatory T cells-derived factors, such as IL-17, IFN-γ, or IL-21, preserve the inflammatory environment. These effects favor strong B cell activation, instigating an extrafollicular antibody response in ectopic lymphoid structures mediated by T follicular helper cells (Tfh) and leading to disease progression. Additionally, the memory effector phenotype of CD8+ T cells present in SS patients suggests that the presence of auto-antigen restricted CD8+ T cells might trigger time-dependent and specific immune responses. Regarding the protective roles of traditional regulatory T cells (Treg), uncertain evidence shows decrease or invariable numbers of circulating and infiltrating cells. Nevertheless, an emerging Treg subset named follicular regulatory T cells (Tfr) seems to play a critical protective role owing to their deficiency that enhances SS development. In this review, the authors summarize the current knowledge of T cells subsets contribution to the SS immunopathology, focusing on the cellular and biomolecular properties allowing them to infiltrate and to harm target tissues, and that simultaneously make them key therapeutic targets for SS treatment.

Abstract
T cells responding to acute infections generally provide two key functions to protect the host: (1) active contribution to pathogen elimination and (2) providing long‐lived cells that are poised to rapidly respond to renewed infection, thus ensuring long‐lasting protection against the particular pathogen. Extensive work has established an astonishing amount of additional diversity among T cells actively contributing to pathogen elimination, as well as among resting, long‐lived antigen‐experienced T cells. This led to the description of a variety of functionally distinct T cell ‘subsets’. Understanding how this heterogeneity develops among T cells responding to the same antigen is currently an active area of research, since knowledge of such mechanisms may have implications for the development of vaccines and immunotherapy. The number of naïve T cells specific to a given antigen span a great range. Considering this, one mechanistic angle focusses on how individual naïve T cells contribute to the development of the distinct T cell subsets. In this review, we highlight the current technologies that enable one to address the contributions of individual naïve T cells to different T cell subsets, with a focus on CD8 T cell subsets generated in the context of acute infections. Moreover, we discuss the requirements of new technologies to further our understanding of the mechanisms that help generate long‐lasting immunity.

Abstract
Background: The protective or pathogenic role of T lymphocytes during the acute phase of dengue virus (DENV) infection has not been fully understood despite its importance in immunity and vaccine development. Objectives: This study aimed to clarify the kinetics of T lymphocyte subsets during the clinical course of acute dengue patients. Study design: In this hospital-based cohort study, 59 eligible Vietnamese dengue patients were recruited and admitted. They were investigated and monitored for T cell subsets and a panel of clinical and laboratory parameters every day until discharged and at post-discharge from the hospital. Results: We described for the first time the kinetics of T cell response during the clinical course of DENV infection. Severe cases showed significantly lower levels of effector CD8+ T cells compared to mild cases at day −1 (p = 0.017) and day 0 (p = 0.033) of defervescence. After defervescence, these cell counts in severe cases increased rapidly to equalize with the levels of mild cases. Our results also showed a decline in total CD4+ T, Th1, Th1/17 cells during febrile phase of dengue patients compared to normal controls or convalescent phase. On the other hand, Th2 cells increased during DENV infection until convalescent phase. Cytokines such as interferon-γ, IL-12p70, IL-5, IL-23, IL-17A showed tendency to decrease on day 0 and 1 compared with convalescence and only IL-5 showed significance indicating the production during acute phase was not systemic. Conclusion: With a rigorous study design, we uncovered the kinetics of T cells in natural DENV infection. Decreased number of effector CD8+ T cells in the early phase of infection and subsequent increment after defervescence day probably associated with the T cell migration in DENV infection.

Abstract
BACKGROUND Ataxia-telangiectasia (AT) is a rare genetic condition, caused by biallelic deleterious variants in the ATM gene, and has variable immunological abnormalities. This study aimed to examine immunologic parameters reflecting cell development, activation, proliferation, and class switch recombination (CSR) and determine their relationship to the clinical phenotype in AT patients. METHODS In this study, 40 patients with a confirmed diagnosis of AT from the Iranian immunodeficiency registry center and 28 age-sex matched healthy controls were enrolled. We compared peripheral B and T cell subsets and T cell proliferation response to CD3/CD28 stimulation in AT patients with and without CSR defects using flow cytometry. RESULTS A significant decrease in naïve, transitional, switched memory, and IgM only memory B cells, along with a sharp increase in the marginal zone-like and CD21low B cells was observed in the patients. We also found CD4+ and CD8+ naïve, central memory, and terminally differentiated effector memory CD4+ (TEMRA) T cells were decreased. CD4+ and CD8+ effector memory, CD8+ TEMRA, and CD4+ regulatory T cells were significantly elevated in our patients. CD4+ T cell proliferation was markedly impaired compared to the healthy controls. Moreover, immunological investigations of 15 AT patients with CSR defect revealed a significant reduction in the marginal zone, switched memory, and more intense defects in IgM only memory B cells, CD4+ naïve and central memory T cells. CONCLUSION The present study revealed that patients with AT have a broad spectrum of cellular and humoral deficiencies. Therefore, a detailed evaluation of T and B cell subsets increases understanding of the disease in patients and the risk of infection.

Abstract
BACKGROUND The dysfunction of the intestinal mucosal barrier plays an important role in the progression of severe acute pancreatitis (SAP), and immunosuppression and immune imbalance can lead to or exacerbate intestinal barrier dysfunction in this process. However, the relationship between various immune function factors and intestinal barrier function has not been characterized.
AIM To explore the relationship between intestinal mucosal barrier function and TLR9 and T cell subsets in patients with SAP.
METHODS The clinical data of 52 patients with SAP diagnosed at our hospital were prospectively selected from January 2018 to January 2020. Plasma endotoxin and D-lactic acid levels, and urine lactulose/mannose (L/M) were detected on the first, second, third, and seventh days. Data on TLR9 levels, inflammation indicators [white blood cells (WBCs), C-reactive protein (CRP), and procalcitonin (PCT)], and T cell subsets (CD3+, CD4+, and CD8+ T cell percentages) were collected. A healthy control group was also included to compare their TLR9 levels with those of SAP patients. The correlation between the intestinal mucosal barrier function and the expression levels of TLR9 and T cell subsets in SAP patients was analyzed.
RESULTS According to DNA analysis of peripheral blood bacteria, the positive rate of bacteria in the 52 patients was 82.69%, including 87 DNA bands and 17 bacteria. Escherichia coli and Bacillus coagulans accounted for the highest proportions (38.89% and 33.33%, respectively). The measurement of WBCs, CRP, and PCT in patients showed that WBC and CRP decreased with time, while PCT increased on the 1st to 3rd days, and decreased on the 7th day (P < 0.05). Serum TLR9 level was higher in SAP patients than in the healthy group, and it rose within 2-3 d after treatment, and decreased after 3 d. Endotoxin, L/M value, and D-lactic acid can well reflect the damage of the intestinal mucosa of patients. The degree of barrier damage after 3 d was lower than the measured value at 2 d. TLR9 was positively correlated with endotoxin (r = 0.792), L/M value (r = 0.668), and D-lactic acid (r = 0.535, P < 0.05). In SAP patients, the expression levels of T cell subgroups were different. The levels of CD3+ and CD4+ T cells showed an upward trend over time. CD8+ T cells declined slightly on the 2nd to 3rd days, and rose slightly after 3 d, showing a downward trend overall. There was a correlation between endotoxin and CD3+ (r = 0.680), CD4+ (r = 0.612), and CD8+ T cells (r = 0.595). The L/M value was significantly correlated with CD3+ (r = 0.680, r = 0.585), CD4+ (r = 0.570), and CD8+ T cells (r = 0.534). D-lactic acid was also significantly correlated with CD3+ (r = 0.515), CD4+ (r = 0.586), and CD8+ T cells (r = 0.510).
CONCLUSION Serum level of TLR9 of SAP patients can reflect the changes in their conditions. The increase in serum TLR9 level indicates the degree of damage to the intestinal mucosal barrier of the patients, and there is a positive correlation between them, suggesting that serum level of TLR9 can be used as a indicator for clinical judgment of the injury of the intestinal mucosal barrier in SAP patients. The correlation between mucosal injury and T cell subsets is significant, which indicates that the suppression of T cell subsets is a protective immune index for SAP patients.

Abstract
BACKGROUND AND AIMS Vedolizumab [VDZ] is a monoclonal antibody directed against the α4β7 integrin heterodimer, approved for patients with inflammatory bowel diseases [IBD]. This study aimed at identifying immunological variables associated with response to vedolizumab in patients with ulcerative colitis [UC] and Crohn's disease [CD]. METHODS This is a phase IV explorative prospective interventional trial. IBD patients received open-label VDZ at Weeks 0, 2, 6, and 14. Patients with a clinical response at Week 14 were maintained with VDZ up to Week 54. At Weeks 0 and 14, their peripheral blood was obtained and endoscopy with biopsies was performed. The Week 14 clinical response and remission, Week 54 clinical remission, and Week 14 endoscopic response were evaluated as endpoints of the study. The expression of surface markers, chemokine receptors, and α4β7 heterodimer in peripheral blood and lamina propria lymphocytes was assessed by flow cytometry. A panel of soluble mediators was assessed in sera at baseline and at Week 14 by 45-plex. RESULTS A total of 38 IBD patients [20 UC, 18 CD] were included in the study. At Week 14, the clinical response and remission rates were 87% and 66%, respectively. Higher baseline levels of circulating memory Th1 cells were strongly associated with clinical response at Week 14 [p = 0.0001], whereas reduced baseline levels of lamina propria memory Th17 and Th1/17 cells were associated with endoscopic response. Immunological clusters were found to be independently associated with vedolizumab outcomes at multivariable analysis. A panel of soluble markers, including IL17A, TNF, CXCL1, CCL19 for CD and G-CSF and IL7 for UC, associated with vedolizumab-induced Week 54 clinical remission. CONCLUSIONS The results of this exploratory study uncovered a panel of circulating and mucosal immunological variables associated with response to treatment with vedolizumab.

Abstract
Objective The pathogenesis of chronic obstructive pulmonary disease (COPD) remains elusive. Here, we assessed the correlation between CD8+ T cell frequencies and autophagy in COPD patients. Methods Subjects were divided into three groups (n = 30 patients/group): (1) COPD patients in the stable phase; (2) smokers with normal lung function; and (3) non-smokers with normal lung function. Flow cytometry was used to enumerate CD8+ T cell subsets (CD8+, CD8+ effector, and CD8+ memory T cells) and quantitate T-cell apoptosis. RT-PCR and western blotting were used to measure levels of LC3 and p62. Results Frequencies of CD8+ T cell subsets and expression of p62 and LC3 II/I were significantly higher in COPD patients compared with the other two groups, while the rate of apoptosis was lower. In COPD patients, LC3 II/I and p62 expression were positively correlated with CD8+ T cell subset frequencies. Moreover, a significant correlation was observed between LC3 II/I and p62 expression and T cell subset frequencies. Conclusion Autophagy level is positively correlated with the frequencies of CD8+ T cells, suggesting that autophagy might be involved in COPD pathogenesis.
