Abstract
Understanding the intricate dynamics between adoptively transferred immune cells and the brain tumor immune microenvironment (TIME) is crucial for the development of effective T cell-based immunotherapies. In this study, we investigated the influence of the TIME and chimeric antigen receptor (CAR) design on the anti-glioma activity of B7-H3-specific CAR T-cells. Using an immunocompetent glioma model, we evaluated a panel of seven fully murine B7-H3 CARs with variations in transmembrane, costimulatory, and activation domains. We then investigated changes in the TIME following CAR T-cell therapy using high-dimensional flow cytometry and single-cell RNA sequencing. Our results show that five out of six B7-H3 CARs with single costimulatory domains demonstrated robust functionality in vitro. However, these CARs had significantly varied levels of antitumor activity in vivo. To enhance therapeutic effectiveness and persistence, we incorporated 41BB and CD28 costimulation through transgenic expression of 41BBL on CD28-based CAR T-cells. This CAR design was associated with significantly improved anti-glioma efficacy in vitro but did not result in similar improvements in vivo. Analysis of the TIME revealed that CAR T-cell therapy influenced the composition of the TIME, with the recruitment and activation of distinct macrophage and endogenous T-cell subsets crucial for successful antitumor responses. Indeed, complete brain macrophage depletion using a CSF1R inhibitor abrogated CAR T-cell antitumor activity. In sum, our study highlights the critical role of CAR design and its modulation of the TIME in mediating the efficacy of adoptive immunotherapy for high-grade glioma. SIGNIFICANCE CAR T-cell immunotherapies hold great potential for treating brain cancers; however, they are hindered by a challenging immune environment that dampens their effectiveness. In this study, we show that the CAR design influences the makeup of the immune environment in brain tumors, underscoring the need to target specific immune components to improve CAR T-cell performance, and highlighting the significance of using models with functional immune systems to optimize this therapy.

Abstract
Lack of targetable antigens is a key limitation for developing successful T cell-based immunotherapies. Members of the unfolded protein response (UPR) represent ideal immunotherapy targets because the UPR regulates the ability of cancer cells to resist cell death, sustain proliferation, and metastasize. Glucose-regulated protein 78 (GRP78) is a key UPR regulator that is overexpressed and translocated to the cell surface of a wide variety of cancers in response to elevated endoplasmic reticulum (ER) stress. We show that GRP78 is highly expressed on the cell surface of multiple solid and brain tumors, making cell surface GRP78 a promising chimeric antigen receptor (CAR) T cell target. We demonstrate that GRP78-CAR T cells can recognize and kill GRP78+ brain and solid tumors in vitro and in vivo. Additionally, our findings demonstrate that GRP78 is upregulated on CAR T cells upon T cell activation; however, this expression is tumor-cell-line specific and results in heterogeneous GRP78-CAR T cell therapeutic response.

Abstract
Metastasis is the principal cause of cancer death, yet we lack an understanding of metastatic cell states, their relationship to primary tumor states, and the mechanisms by which they transition. In a cohort of biospecimen trios from same-patient normal colon, primary and metastatic colorectal cancer, we show that while primary tumors largely adopt LGR5 + intestinal stem-like states, metastases display progressive plasticity. Loss of intestinal cell states is accompanied by reprogramming into a highly conserved fetal progenitor state, followed by non-canonical differentiation into divergent squamous and neuroendocrine-like states, which is exacerbated by chemotherapy and associated with poor patient survival. Using matched patient-derived organoids, we demonstrate that metastatic cancer cells exhibit greater cell-autonomous multilineage differentiation potential in response to microenvironment cues than their intestinal lineage-restricted primary tumor counterparts. We identify PROX1 as a stabilizer of intestinal lineage in the fetal progenitor state, whose downregulation licenses non-canonical reprogramming.

Abstract
Understanding interactions between adoptively transferred immune cells and the tumor immune microenvironment (TIME) is critical for developing successful T-cell based immunotherapies. Here we investigated the impact of the TIME and chimeric antigen receptor (CAR) design on anti-glioma activity of B7-H3-specific CAR T-cells. We show that five out of six B7-H3 CARs with varying transmembrane, co-stimulatory, and activation domains, exhibit robust functionality in vitro. However, in an immunocompetent glioma model, these CAR T-cells demonstrated significantly varied levels of anti-tumor activity. We used single-cell RNA sequencing to examine the brain TIME after CAR T-cell therapy. We show that the TIME composition was influenced by CAR T-cell treatment. We also found that successful anti-tumor responses were supported by the presence and activity of macrophages and endogenous T-cells. Together, our study demonstrates that efficacy of CAR T-cell therapy in high-grade glioma is dependent on CAR structural design and its capacity to modulate the TIME.

Abstract
Objective: To analyze the allocation of human resources for chronic disease prevention and control of district/county-level centers for disease control and prevention(CDC) in China in 2020. Methods: Survey subjects were from National Chronic Noncommunicable Disease and Risk Factor Surveillance Sites and National Demonstration Areas for Chronic Noncommunicable Disease Prevention and Control (demonstration areas). A survey examining the allocation of human resources for chronic disease prevention and control at district/county-level CDC was conducted in December 2021 through the National Demonstration Areas Management Information System. The number and rate of allocation of human resources for chronic disease prevention and control in district/county-level CDC were analyzed and the Wilcoxon rank sum test was used to compare the difference between demonstration and non-demonstration areas and between urban and rural areas. The Kruskal-Wallis H test was used to compare the difference in east, central and west regions. The Gini coefficient and Theil index were used to evaluate the balance of human resource for chronic disease prevention and control. Results: A total of 678 districts/counties were investigated, and 664 districts/counties responded effectively, with an effective response rate of 97.9%. The establishment rate of district/county-level CDC was 98.34% (653/664), and the establishment rate of chronic disease prevention and control departments of district/county-level CDC was 96.02% (627/653). In 627 district/county-level CDC with departments for chronic disease prevention and control, the median number of full-time technical personnel for chronic disease prevention and control was 4, the median number of full-time technical personnel in demonstration areas (4 persons) was higher than in non-demonstration areas (3 persons), highest in the east region (5 persons) than in the middle region (4 persons) and the west region (4 persons), higher in urban areas (4 persons) than in rural areas (4 persons) (all P values<0.05). The allocation rate was 0.71 people/100 000, which was higher in demonstration areas (0.73 people/100 000) than in non-demonstration areas (0.67 people/100 000), highest in the west region (0.82 people/100 000) than in the middle region (0.71 people/100 000) and east region (0.67 people/100 000), higher in rural areas (0.77 people/100 000) than in urban areas (0.68 people/100 000) (all P values<0.05). The Gini coefficient for the allocation by population size was 0.352 9. The total Theil index for demonstration and non-demonstration areas, different regions, and urban-rural areas were 0.067 8, 0.076 3, and 0.000 2, with the intra-group contribution of 97.35%, 99.52%, and 98.80%, respectively. Conclusion: In 2020, the allocation of human resources for chronic disease prevention and control in district/county-level CDC is relatively balanced. The variation in the allocation of human resources for chronic disease prevention and control exist between demonstration and non-demonstration areas, urban and rural areas, and across regions.

Abstract
We and others have demonstrated that B7-H3 CAR T-cells have potent antitumor responses in xenograft models for brain tumors; however, these models do not recapitulate the immunosuppressive tumor microenvironment (TME) in patients with high-grade glioma. To evaluate the safety and efficacy of antigen-specific CAR T-cells, we adapted the immune-competent GL261 glioma model which recapitulates human disease and host immune barriers. We generated a library of B7-H3 CARs with different transmembrane (CD8, CD28), costimulatory (CD28, 4-1BB), and activation (ζ, mutζ) domains. We then compared their cytolytic activity, expansion, and anti-tumor activity. Results show that B7-H3 CARs with CD28 transmembrane and costimulatory domains have superior efficacy compared to CARs with CD8 and 4-1BB domains. Additionally, CARs with mutated ζ activation domain have better overall persistence. However, providing costimulation signals through CD28 or 4-1BB alone does not induce superior anti-glioma efficacy of B7-H3 CAR T-cells in vivo. Thus, we next investigated whether incorporating 4-1BB signaling into CD28-based CARs using in trans design enhances the therapeutic efficacy of B7-H3 CAR T-cells. We found that in repeat stimulation assays, surface expression of 4-1BBL enhanced expansion of B7H3 CAR T-cells at least 300-folds more than T-cells with CD28 or 4-1BB costimulatory domains alone. Additionally, 4-1BBL expression significantly enhanced the sequential killing capacity compared to CD28- or 41BB-based B7-H3 CAR T-cells. High dimensional flow cytometry analysis of GL261 tumors post CAR T-cell injection revealed unique immune clusters including dendritic cells and lymphoid predominant populations in mice treated with 4-1BBL expressing CARs. Thus, expression of 4-1BBL on CD28-based CARs reshaped the TME and enhanced persistence and anti-glioma efficacy of B7-H3 CAR T-cells. Studies examining transcriptional and epigenetic programs, and TME/CAR T-cell interactions are in progress. Results will define pathways that dictate CAR T-cell performance and will identify unique mechanisms for further improvements utilizing other members of TNF-superfamily.

Abstract
BackgroundCT-P13 is an approved biosimilar to EU-approved and US-licensed Infliximab (INX) for the indications of rheumatoid arthritis (RA), adult and paediatric Crohn’s disease, adult and paediatric ulcerative colitis, ankylosing spondylitis, psoriatic arthritis and psoriasis.ObjectivesThe purpose of this study was to demonstrate equivalence of efficacy and compare PK and safety profiles of CT-P13 and China-approved INX.MethodsIn this randomized, double blinded, multicenter, parallel-group, phase III study, patients with active RA who had been responding inadequately to methotrexate for at least 3 months, were randomized to receive either CT-P13 or China-approved INX. Patients were treated with doses of 3 mg/kg at Weeks 0, 2, 6, then every 8 weeks up to Week 54. Prior to dosing at Week 30, patients randomized to China-approved INX underwent a second randomization either to continue China-approved INX or to switch to CT-P13 at Week 30. Results of patients who underwent transition to CT-P13 were included in the China-approved INX group. The primary efficacy endpoint was change in DAS28 (CRP) from baseline to Week 14, which was analyzed using an analysis of covariance. Equivalence was determined if the 90% CI for the estimate of treatment difference was entirely contained within the predefined equivalence margin of -0.6 to 0.6.Results270 patients were randomly assigned to 2 treatment groups in a 1:1 ratio (136 and 134 patients in the CT-P13 and China-approved INX groups, respectively) and 184 patients completed the study. The least square mean change (standard error) of DAS28 (CRP) from baseline to Week 14, -1.566 [0.1419] and -1.547 [0.1491], was similar between the CT-P13 and China-approved INX groups, respectively. The 90% CI for the estimate of treatment difference (-0.29, 0.25) was contained within the predefined equivalence margin, which demonstrated therapeutic equivalence between the groups. The mean actual values for DAS28 (CRP) decreased from baseline to Week 54 and were similar between the groups (Figure 1). Additional efficacy endpoints, including ACR responses (ACR20 at Week 14; 60.6%, 54.8% and at Week 54; 65.1%, 60.6% in the CT-P13 and China-approved INX groups, respectively), EULAR responses, CDAI, and SDAI, were similar between the groups, even after switching at Week 30. During the study, mean serum INX concentrations were similar between the groups. Between Weeks 14 and 22, mean (percent coefficient of variation) AUCτ were 11156333.615 (44.796) ng·h/mL and 11462884.280 (51.057) ng·h/mL, and Cmax,ss were 66577.2 (31.4) ng/mL and 66356.1 (21.0) ng/mL in the CT-P13 and China-approved INX groups, respectively, which were similar between the groups. Most treatment-emergent AEs were grade 1 or 2 in intensity. One malignancy was reported in the CT-P13 group and no deaths were reported. The proportions of patients with anti-drug antibodies were similar between the groups, even after switching at Week 30. The overall safety profile of CT-P13 was comparable to that of China-approved INX and no new safety issues were observed (Table 1).Table 1.Summary of Safety ResultsNumber of patients (%)CT-P13 (N=136)China-approved Infliximab (N=133)Treatment-emergent AEsTotal115 (84.6%)107 (80.5%)Related97 (71.3%)86 (64.7%)Treatment-emergent serious AEsTotal17 (12.5%)12 (9.0%)Related10 (7.4%)6 (4.5%)Infusion related reaction/ hypersensitivity/anaphylactic reactionsTotal(=Related)20 (14.7%)19 (14.3%)InfectionsTotal45 (33.1%)43 (32.3%)Related36 (26.5%)40 (30.1%)Note: Summary is presented for the safety population who received at least 1 dose (full or partial) of study drug.ConclusionThe study demonstrated that efficacy of CT-P13 is equivalent to that of China-approved INX.

Abstract
Chimeric antigen receptor (CAR) T cell therapy is revolutionizing cancer immunotherapy for patients with B cell malignancies and is now being developed for solid tumors and chronic viral infections. Although clinical trials have demonstrated the curative potential of CAR T cell therapy, a substantial and well-established limitation is the heightened contraction and transient persistence of CAR T cells during prolonged antigen exposure. The underlying mechanism(s) for this dysfunctional state, often termed CAR T cell exhaustion, remains poorly defined. Here, we report that exhaustion of human CAR T cells occurs through an epigenetic repression of the T cell’s multipotent developmental potential. Deletion of the de novo DNA methyltransferase 3 alpha (DNMT3A) in T cells expressing first- or second-generation CARs universally preserved the cells’ ability to proliferate and mount an antitumor response during prolonged tumor exposure. The increased functionality of the exhaustion-resistant DNMT3A knockout CAR T cells was coupled to an up-regulation of interleukin-10, and genome-wide DNA methylation profiling defined an atlas of genes targeted for epigenetic silencing. This atlas provides a molecular definition of CAR T cell exhaustion, which includes many transcriptional regulators that limit the “stemness” of immune cells, including CD28, CCR7, TCF7, and LEF1. Last, we demonstrate that this epigenetically regulated multipotency program is firmly coupled to the clinical outcome of prior CAR T cell therapies. These data document the critical role epigenetic mechanisms play in limiting the fate potential of human T cells and provide a road map for leveraging this information for improving CAR T cell efficacy.

Abstract
OBJECTIVE The aim of the study was to analyze spatiotemporal changes of CT manifestations in patients with COVID-19 pneumonia. PATIENTS AND METHODS In this retrospective review, 110 patients with confirmed COVID-19 by RT-PCR form February 16, 2020, to March 28, 2020 were included. A total of 449 CT scans were reviewed. We analyze the type and distribution of lung abnormalities, and CT general assessment and lesion area statistics were performed. Patients were divided into mild, moderate, and severe disease based on Chinese guidelines: mild (patients with minimal symptoms, CT scans showed no pneumonia or a small area of pneumonia infection), moderate (different extent of clinical manifestations and CT scans showed multiple pneumonia infections in both lungs), severe disease (respiratory distress, CT scans lesion area exceeds 50%, and the lesion contains consolidation). The proportion of patients with mild, moderate and severe diseases was counted. RESULTS The CT score and the area involved reached a peak (median 10) on illness days 7-12, and then, continued to be at a high level. The main abnormal pattern after symptoms appeared GGO (36/94 [36%] to 40/65 [62%] in different periods). The proportion of mixed reached its peak on illness days 13-18 (36/93 [39%]). Pure GGO was the most common subtype of GGO (24 of 60 CT scans [40%] to 23 of 33 CT scans [70%]) after symptoms onset. The ratio of GGO with irregular lines and interfaces peaked on illness days 7-12 (6/34 [18%]). The lesions are mainly distributed on both sides and under the pleura. 76/84 (90%) of discharged patients had residual lesions on the final CT scans. 4 confirmed patients' CT scans did not show lesions (on illness days 1-24 days). There were 47 mild cases (42.7%), 46 moderate cases (41.8%), and 7 severe cases (6.3%). CONCLUSIONS The degree of lung abnormality on the CT of the patients reached the peak on the 7th to 12th days of the disease. CT performance changes with time have a certain regularity, which may indicate the progress and recovery of the disease. 90% of patients still observed residual lung abnormalities in CT images at the time of discharge. There were 4 confirmed cases where the CT images did not show the lesion; hence, CT cannot be used as a basis for judging COVID-19 as a single tool.

Abstract
BACKGROUND Immunotherapy with chimeric antigen receptor (CAR) T cells is actively being explored for pediatric brain tumors in preclinical models and early phase clinical studies. At present, it is unclear which CAR target antigens are consistently expressed across different pediatric brain tumor types. In addition, the extent of HLA class I expression is unknown, which is critical for tumor recognition by conventional αβTCR T cells. METHODS We profiled 49 low- and high-grade pediatric brain tumor patient-derived orthotopic xenografts (PDOX) by flow analysis for the expression of 5 CAR targets (B7-H3, GD2, IL-13Rα2, EphA2, and HER2), and HLA class I. In addition, we generated B7-H3-CAR T cells and evaluated their antitumor activity in vitro and in vivo. RESULTS We established an expression hierarchy for the analyzed antigens (B7-H3 = GD2 >> IL-13Rα2 > HER2 = EphA2) and demonstrated that antigen expression is heterogenous. All high-grade gliomas expressed HLA class I, but only 57.1% of other tumor subtypes had detectable expression. We then selected B7-H3 as a target for CAR T-cell therapy. B7-H3-CAR T cells recognized tumor cells in an antigen-dependent fashion. Local or systemic administration of B7-H3-CAR T cells induced tumor regression in PDOX and immunocompetent murine glioma models resulting in a significant survival advantage. CONCLUSIONS Our study highlights the importance of studying target antigen and HLA class I expression in PDOX samples for the future design of immunotherapies. In addition, our results support active preclinical and clinical exploration of B7-H3-targeted CAR T-cell therapies for a broad spectrum of pediatric brain tumors.

Abstract
BACKGROUND We and others have identified B7-H3 (CD276) as a promising target for CAR-based immunotherapies for pediatric brain tumors. So far, B7-H3-CAR T cells have only been studied in xenograft models for brain tumors, which do not recapitulate the immunosuppressive tumor microenvironment (TME). To overcome this obstacle, we decided to adapt the immune-competent GL261 murine glioma model which mimics human disease and host immune barriers. METHODS To evaluate the safety and efficacy of antigen-specific CAR T cells, murine B7-H3-CAR T cells were generated using retroviral particles encoding 2nd generation B7-H3-specific CD28.z CAR. Expansion, persistence, and anti-tumor activity were evaluated in vitro and in vivo. Components of the brain TME were then evaluated using flow cytometry and immunostaining. RESULTS B7-H3-CAR T cells only killed B7-H3+ tumor cells, secreted significant levels of IFNγ and IL-2 in an antigen-dependent manner and expanded an average of 33-fold in repeat stimulation assay with B7-H3+ tumor cells in contrast to control CAR T cells. In vivo, intratumoral injection of B7-H3-CAR T cells into orthotopic GL261 glioma induced complete regression in 60% of treated mice. Preliminary studies show numerous infiltration of suppressive tumor-associated macrophages within the tumor and its periphery. CONCLUSIONS In summary, we successfully generated murine B7-H3-CAR T cells and have demonstrated that these cells have potent anti-tumor activity in the immune-competent GL261 glioma model. However, it is likely that the tumor-associated macrophages are mediating immunosuppressive effects on B7-H3-CAR T cells. Therefore, studies focusing on TME/CAR T cell interactions are in progress.

Abstract
Tacrolimus (Tac) is an effective anti-rejection agent in kidney transplantation, but its off-target effects make withdrawal desirable. Although studies indicate that Tac can be safely withdrawn in a subset of kidney transplant recipients, immune mechanisms that underlie successful vs unsuccessful Tac removal are unknown. We performed microarray analyses of peripheral blood mononuclear cells (PBMC) RNA from subjects enrolled in the Clinical Trials in Organ Transplantation-09 study in which we randomized stable kidney transplant recipients to Tac withdrawal or maintenance of standard immunosuppression beginning 6 months after transplant. Eight of 14 subjects attempted but failed withdrawal, while six developed stable graft function for ≥2 years on mycophenolate mofetil plus prednisone. Whereas failed withdrawal upregulated immune activation genes, successful Tac withdrawal was associated with a downregulatory and proapoptotic gene program enriched within T cells. Functional analyses suggested stronger donor-reactive immunity in subjects who failed withdrawal without evidence of regulatory T cell dysfunction. Together, our data from a small, but unique, patient cohort support the conclusion that successful Tac withdrawal is not simply due to absence of donor-reactive immunity but rather is associated with an active immunological process.

Abstract
BACKGROUND
We and others have identified B7-H3 (CD276) as a promising target for CAR T-cell-based immunotherapies for pediatric brain tumors. So far, B7-H3-CAR T cells have only been studied in xenograft models for brain tumors, which do not recapitulate the immunosuppressive tumor microenvironment (TME). To overcome this obstacle, we decided to adapt the immune competent GL261 murine glioma model which mimics human disease and host immune barriers.
METHODS
To evaluate their safety and efficacy, murine B7-H3-CAR T-cells were generated using retroviral particles encoding a 2nd generation B7-H3-CAR with a CD28.z signaling domain. Expansion, persistence, and anti-tumor activity were evaluated in vitro and in vivo. Components of the brain TME were then evaluated using flow cytometry and immunostaining.
RESULTS
B7-H3-CAR T cells only killed B7-H3+ tumor cells, secreted significant levels of IFNγ and IL-2 in an antigen-dependent manner and expanded an average of 85-fold in repeat stimulation assay with B7-H3+ tumor cells in contrast to control CAR T-cells. In vivo, intratumoral (2x106) or systemic (3x106) injection of syngeneic B7-H3-CAR T-cells into mice with orthotopic GL261 glioma induced complete regression in 60% of treated mice resulting in a significant survival advantage. Mice showed no evidence of acute or long-term toxicities related to CAR T-cell infusions. We confirmed this encouraging safety profile by systemic administration of a high dose (1x107) B7-H3-CAR T-cells and performing histological analyses of all major organs on day 14 post T-cell injection, which showed no notable signs of injury or on-target/off-tumor toxicities.
CONCLUSIONS
We successfully generated syngeneic B7-H3-CAR T-cells and have demonstrated that these cells have potent anti-tumor activity in the immune competent GL261 glioma model via local or systemic delivery without apparent toxicities. Our study paves the way for future testing of B7-H3-CAR T-cells in early phase clinical studies.

Abstract
Chimeric antigen receptor (CAR) T-cell therapy is revolutionizing cancer immunotherapy for patients with B cell malignancies. While clinical trials have demonstrated the curative potential of this approach, a significant and well-established limitation is the heightened contraction and transient persistence that CAR T-cells experience during prolonged antigen exposure. Building upon our prior observation that deleting the de novo DNA methyltransferase 3a (Dnmt3a) prevents T cell exhaustion in the prototypical model of LCMV-induced T cell exhaustion, we assessed the role of DNMT3A programming in the dysfunction of human CAR T-cells. Deletion of DNMT3A in multiple human CAR T-cell systems resulted in a striking preservation of the CAR T-cell’s ability to proliferate and mount an effector response during chronic antigen exposure. Whole genome methylation profiling of DNMT3A KO CAR T-cells established an atlas of epigenetically regulated genes targeted during CAR T-cell dysfunction. Cross-reference of our published murine exhaustion methylation profiles with our newly identified human CAR T-cell methylation atlas revealed conservation of epigenetically regulated exhaustion-associated genes. Using a novel epigenetic-based bioinformatic tool that predicts human T-cell differentiation we further documented the preserved developmental plasticity of the DNMT3A KO CAR T-cells. Lastly, analysis of publicly available RNAseq expression data from CD19-CAR T-cell products prior to infusion into CLL patients demonstrated that DNMT3A programming is significantly coupled to clinical outcome. Collectively our results demonstrate that de novo DNA methylation programming is a key factor limiting T-cell based immunotherapy.

Abstract
Budd-Chiari syndrome (BCS) is a rare disease characterized by obstruction of hepatic venous outflow tract with diversified etiologies. Sea-blue histiocytosis (SBH) is a kind of storage diseases defined by the deposition of abundant sea-blue histiocytes in various organs and can lead to hepatosplenomegaly, cirrhosis, or even liver failure. The association between BCS and SBH has never been reported before. Here, we report a patient with BCS presenting with hepatosplenomegaly, portal hypertension, and pancytopenia who was later confirmed to also have SBH.

Abstract
Paired soil and plant samples collected from the main commercial growing areas for onions (Allium cepa), lettuce (Lactuca sativa) and spinach (Spinacia olearacea) in New Zealand were used to assess the influence of plant and soil factors on cadmium (Cd) uptake in these crops. Differences in Cd concentration between eight lettuce sub-types were not consistent across sites, nor were differences in Cd concentrations in three crisphead cultivars assessed at two sites. Similarly, differences in Cd concentrations between four onion cultivars were inconsistent across sites. Mean lettuce Cd concentrations in eight lettuce varieties (range 0.005-0.034 mg∙kg-1 (fresh weight, FW) were markedly lower than those in baby leaf and bunching spinach, (range 0.005-0.19 mg∙kg-1 FW). Significant regional variation was observed in Cd concentrations in one onion cultivar (mean range 0.007-0.05 mg∙kg-1 FW). Soil Cd concentration, pH and region were statistically significant predictors of onion Cd concentration, explaining low (38% for soil Cd and pH) to moderate (50% for all three parameters) percentage of the variation. Soil Cd concentration and exchangeable magnesium or total carbon were statistically significant predictors of Cd concentration in baby leaf and bunching spinach, respectively, explaining a moderate percentage (49% and 42%) of the variation in Cd concentration. Increasing pH and soil carbon may assist in minimising Cd uptake in onion and bunching spinach, respectively. The low to moderate proportion of explained variation is partly attributable to the narrow range in some measured soil properties and indicates factors other than those assessed are influencing plant uptake. This highlights a challenge in using these relationships to develop risk-based soil guideline values to support compliance with food standards. Similarly, the inconsistency in Cd concentrations in different cultivars across sites highlights the need for multi-site assessments to confirm the low Cd accumulation status of different cultivars.

Abstract
Objective: To explore the regulatory mechanism of E2F1 transcription factor on M2 macrophages in full-thickness skin defect wounds of mice. Methods: E2F1 gene knockout heterozygotes C57BL/6 mice and wild-type C57BL/6 mice were introduced and self-reproduced. Two weeks after birth, E2F1 gene knockout homozygotes mice and wild-type mice were identified by polymerase chain reaction (PCR). Twelve identified 6-8 weeks old male E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were selected respectively according to the random number table and set as E2F1 gene knockout group and wild-type group. A full-thickness skin defect wound was made on the back of each mouse. On post injury day (PID) 2 and 7, 6 mice in each group were selected according to the random number table and sacrificed, and the wound tissue was excised. The expression of CD68 and CD206 double positive M2 macrophages was observed by immunofluorescence method, and the percentage of CD206 positive cells was calculated. The protein expression of CD206 was detected by Western blotting. The mRNA expression of arginase 1 was detected by real-time fluorescent quantitative reverse transcription PCR (RT-PCR). Wound tissue specimens of the two groups on PID 7 were obtained, and the protein and mRNA expressions of peroxisome proliferator-activated receptor gamma (PPAR-γ) were detected by Western blotting and real-time fluorescent quantitative RT-PCR respectively. The above-mentioned experiments were repeated four times. Three specimens of wound tissue of mice in wild-type group on PID 7 were obtained to detect the relationship between E2F1 and PPAR-γ by co-immunoprecipitation and Western blotting, and this experiment was repeated two times. Data were processed with unpaired t test. Results: The size of PCR products of E2F1 gene knockout homozygotes C57BL/6 mice and wild-type C57BL/6 mice were 227 and 172 bp respectively, which were the same as those of the designed DNA fragments. On PID 2 and 7, the number of CD68 and CD206 double positive M2 macrophages in the wound tissue of mice in E2F1 gene knockout group was more than that of wild-type group, and the percentages of CD206 positive cells in the wound tissue of mice in E2F1 gene knockout group were (0.234±0.032)% and (0.584±0.023)% respectively, which were significantly higher than (0.129±0.017)% and (0.282±0.071)% of wild-type group (t=3.29, 3.54, P<0.05). On PID 2 and 7, the protein expression of CD206 in the wound tissue of mice in E2F1 gene knockout group were 1.00±0.23 and 1.63±0.26 respectively, which were significantly higher than 0.43±0.06 and 0.97±0.08 of wild-type group (t=2.41, 2.45, P<0.05). On PID 2 and 7, the mRNA expressions of arginase 1 in the wound tissue of mice in E2F1 gene knockout group were 0.482±0.105 and 0.195±0.031 respectively, which were significantly higher than 0.163±0.026 and 0.108±0.017 of wild-type group (t=3.04, 2.86, P<0.05). On PID 7, the protein and mRNA expressions of PPAR-γ in the wound tissue of mice in E2F1 gene knockout group were 0.61±0.12 and 0.51±0.13 respectively, which were significantly higher than 0.20±0.04 and 0.20±0.04 of wild-type group (t=3.36, 2.86, P<0.05). On PID 7, detection of the wound tissue of mice in wild-type group showed that PPAR-γ had unidirectional effect on E2F1. Conclusions: E2F1 transcription factor affects the polarization of M2 macrophages by inhibiting the expression of PPAR-γ, thereby inhibiting the healing process of full-thickness skin defect wounds in mice.

Abstract
In vitro produced β-like cells can provide promising cell therapy for curing the epidemic of diabetes. In this context, we aimed to investigate the effects of different concentrations of γ-aminobutyric acid (GABA) on the differentiation of rat pancreatic ductal epithelial-like stem cells (PDESCs) into β-like cells. The PDESC line cells were cultured in the basal media (DMEM/F12 + 10% FBS + 1% penicillinstreptomycin) supplemented with 0 μM, 5 μM, 50 μM, 500 μM, and 5 mM of GABA for 28 days to induce their differentiation. The differentiated cells were detected by cell morphology, dithizone (DTZ) staining, immunofluorescence staining, real-time polymerase chain reaction (qPCR), and glucose-stimulated insulin secretion (GSIS) assay to validate their identity. At the end of 28 days, compared with the control group, enrichment of induced cells was high among the 5 μM, 50 μM, 500 μM, and 5 mM GABA induction groups. The formation of islet-like cell clusters (ICCs) began at 14 days, and the cell clusters showed a growth trend with the culture time. The induced ICCs were positive for DTZ staining, while the control group showed negative results for DTZ staining and the differentiated cells were also positive for β-cell-specific markers (Ins1 and Pdx1). GSIS assay of 50 μM induction group cells at 28 days showed significantly higher levels of C-peptide and insulin secretion than the control, 5 μM, 500 μM, and 5 mM GABA-treated groups (P < 0.01). At the same time, the 50 μM induction group cells also showed significantly higher levels of Ins1, Pdx1 and Nkx6.1 mRNA as compared to the 5 μM, 500 μM and 5 mM GABA groups (P < 0.01). Thus, the addition of GABA to the basal medium effectively induced differentiation of adult rat PDESCs into insulin-secreting β-like cells, and 50 μM was the most effective concentration for the induction.

Abstract
BACKGROUND Preserving the donor's gallbladder during living donor liver transplantation (LDLT) is a better method for liver transplantation surgery, but not enough is known about gallbladder complications after the operation. METHODS We retrospectively investigated postsurgical donor gallbladder complications in clinical LDLT with gallbladder preservation. The feasibility of retaining the gallbladder during liver graft procurement is discussed. Ninety-one donors with retained gallbladder after LDLT with the hepatic left lateral sectionectomy (from June 2013 to October 2015) were retrospectively analyzed. Donors were followed for 12.6 to 40.7 months after surgery (median 26.1 months). Sonography was used to evaluate gallbladder characteristics before and after surgery. RESULTS Gallbladder function had recovered to almost normal 1 month after transplantation. Four donors (4.40%) experienced gallbladder enlargement that resolved after 3 days. Thickening of the gallbladder wall in 31 donors (34.07%) was restored within 2 to 75 days. Biliary sludge appeared in 9 donors (9.89%); 6 of them recovered within 3 to 34 days. Three (3.30%) and 1 donor (1.10%) suffered gallstone and gallbladder polyps, respectively, which persisted until the last follow-up. CONCLUSION The rate of postoperative complications of the gallbladder in donors was relative low. Preserving the gallbladder in liver transplantation donors during liver graft procurement is feasible and safe.

Abstract
BACKGROUND Chronic hepatitis B virus (HBV) infection remains incurable. Although HBsAg-specific chimeric antigen receptor (HBsAg-CAR) T cells have been generated, they have not been tested in animal models with authentic HBV infection. METHODS We generated a novel CAR targeting HBsAg and evaluated its ability to recognize HBV+ cell lines and HBsAg particles in vitro. In vivo, we tested whether human HBsAg-CAR T cells would have efficacy against HBV-infected hepatocytes in human liver chimeric mice. RESULTS HBsAg-CAR T cells recognized HBV-positive cell lines and HBsAg particles in vitro as judged by cytokine production. However, HBsAg-CAR T cells did not kill HBV-positive cell lines in cytotoxicity assays. Adoptive transfer of HBsAg-CAR T cells into HBV-infected humanized mice resulted in accumulation within the liver and a significant decrease in plasma HBsAg and HBV-DNA levels compared with control mice. Notably, the fraction of HBV core-positive hepatocytes among total human hepatocytes was greatly reduced after HBsAg-CAR T cell treatment, pointing to noncytopathic viral clearance. In agreement, changes in surrogate human plasma albumin levels were not significantly different between treatment and control groups. CONCLUSIONS HBsAg-CAR T cells have anti-HBV activity in an authentic preclinical HBV infection model. Our results warrant further preclinical exploration of HBsAg-CAR T cells as immunotherapy for HBV.

Abstract
Importance Glioblastoma is an incurable tumor, and the therapeutic options for patients are limited. Objective To determine whether the systemic administration of HER2-specific chimeric antigen receptor (CAR)-modified virus-specific T cells (VSTs) is safe and whether these cells have antiglioblastoma activity. Design, Setting, and Participants In this open-label phase 1 dose-escalation study conducted at Baylor College of Medicine, Houston Methodist Hospital, and Texas Children's Hospital, patients with progressive HER2-positive glioblastoma were enrolled between July 25, 2011, and April 21, 2014. The duration of follow-up was 10 weeks to 29 months (median, 8 months). Interventions Monotherapy with autologous VSTs specific for cytomegalovirus, Epstein-Barr virus, or adenovirus and genetically modified to express HER2-CARs with a CD28.ζ-signaling endodomain (HER2-CAR VSTs). Main Outcomes and Measures Primary end points were feasibility and safety. The key secondary end points were T-cell persistence and their antiglioblastoma activity. Results A total of 17 patients (8 females and 9 males; 10 patients ≥18 years [median age, 60 years; range, 30-69 years] and 7 patients <18 years [median age, 14 years; range, 10-17 years]) with progressive HER2-positive glioblastoma received 1 or more infusions of autologous HER2-CAR VSTs (1 × 106/m2 to 1 × 108/m2) without prior lymphodepletion. Infusions were well tolerated, with no dose-limiting toxic effects. HER2-CAR VSTs were detected in the peripheral blood for up to 12 months after the infusion by quantitative real-time polymerase chain reaction. Of 16 evaluable patients (9 adults and 7 children), 1 had a partial response for more than 9 months, 7 had stable disease for 8 weeks to 29 months, and 8 progressed after T-cell infusion. Three patients with stable disease are alive without any evidence of progression during 24 to 29 months of follow-up. For the entire study cohort, median overall survival was 11.1 months (95% CI, 4.1-27.2 months) from the first T-cell infusion and 24.5 months (95% CI, 17.2-34.6 months) from diagnosis. Conclusions and Relevance Infusion of autologous HER2-CAR VSTs is safe and can be associated with clinical benefit for patients with progressive glioblastoma. Further evaluation of HER2-CAR VSTs in a phase 2b study is warranted as a single agent or in combination with other immunomodulatory approaches for glioblastoma.

Abstract
Successful adoptive T-cell immunotherapy of solid tumors will require improved expansion and cytotoxicity of tumor-directed T cells within tumors. Providing recombinant or transgenic cytokines may produce the desired benefits but is associated with significant toxicities, constraining clinical use. To circumvent this limitation, we constructed a constitutively signaling cytokine receptor, C7R, which potently triggers the IL7 signaling axis but is unresponsive to extracellular cytokine. This strategy augments modified T-cell function following antigen exposure, but avoids stimulating bystander lymphocytes. Coexpressing the C7R with a tumor-directed chimeric antigen receptor (CAR) increased T-cell proliferation, survival, and antitumor activity during repeated exposure to tumor cells, without T-cell dysfunction or autonomous T-cell growth. Furthermore, C7R-coexpressing CAR T cells were active against metastatic neuroblastoma and orthotopic glioblastoma xenograft models even at cell doses that had been ineffective without C7R support. C7R may thus be able to enhance antigen-specific T-cell therapies against cancer.Significance: The constitutively signaling C7R system developed here delivers potent IL7 stimulation to CAR T cells, increasing their persistence and antitumor activity against multiple preclinical tumor models, supporting its clinical development.

Abstract
BACKGROUND/OBJECTIVES To gain further insight into the role of adipocyte mitochondria in systemic lipid metabolism, inflammation and insulin sensitivity in humans and to provide a better understanding of the mechanisms of action of the peroxisome proliferator-activated receptor gamma agonist pioglitazone. SUBJECTS/METHODS Mitochondrial DNA (mtDNA) copy number, mitochondrial distribution, mitochondrial and overall cellular protein abundances as well as intrinsic mitochondrial function of subcutaneous adipocytes were assessed by real-time quantitative PCR, MitoTracker staining, global proteomics analyses and NADH cytochrome c reductase activity in insulin-sensitive, normal-glucose-tolerant (NGT) individuals and age, gender, adiposity-matched insulin-resistant individuals with abnormal glucose tolerant (AGT) before and after 3 months of pioglitazone treatment. RESULTS mtDNA copy number/adipocyte and mtDNA copy number/adipocyte volume were ~55% and ~4-fold lower in AGT than in NGT, respectively, and correlated positively with the M-value of euglycemic clamps and high-density lipoprotein, and negatively with fasting plasma triglyceride, tumor necrosis factor-α and interleukin-6 levels in the entire cohort. mtDNA copy number/adipocyte volume also correlated positively with plasma adiponectin. Pioglitazone, which improved insulin sensitivity, plasma lipids and inflammation, increased the mitochondrial copy number, and led to a redistribution of mitochondria from a punctate to a more reticular pattern as observed in NGT. This was accompanied by disproportionately increased abundances of mitochondrial proteins, including those involved in fat oxidation and triglyceride synthesis. Pioglitazone also increased the abundance of collagen VI and decreased the abundance of cytoskeletal proteins. NADH cytochrome c reductase activity of isolated adipocyte mitochondria was similar in AGT and NGT and unaltered by pioglitazone. CONCLUSIONS Adipocyte mitochondria are deficient in insulin-resistant individuals and correlate with systemic lipid metabolism, inflammation and insulin sensitivity. Pioglitazone induces mitochondrial biogenesis and reorganization as well as the synthesis of mitochondrial proteins including those critical for lipid metabolism. It also alters extracellular matrix and cytoskeletal proteins. The intrinsic function of adipocyte mitochondria appears unaffected in insulin resistance and by pioglitazone.International Journal of Obesity advance online publication, 31 October 2017; doi:10.1038/ijo.2017.192.

Abstract
Glioblastoma (GBM) is the most aggressive primary brain tumor in adults and is virtually incurable with conventional therapies. Immunotherapy with T cells expressing GBM-specific chimeric antigen receptors (CAR) is an attractive approach to improve outcomes. Although CAR T cells targeting GBM antigens, such as IL13 receptor subunit α2 (IL13Rα2), HER2, and EGFR variant III (EGFRvIII), have had antitumor activity in preclinical models, early-phase clinical testing has demonstrated limited antiglioma activity. Transgenic expression of IL15 is an appealing strategy to enhance CAR T-cell effector function. We tested this approach in our IL13Rα2-positive glioma model in which limited IL13Rα2-CAR T-cell persistence results in recurrence of antigen-positive gliomas. T cells were genetically modified with retroviral vectors encoding IL13Rα2-CARs or IL15 (IL13Rα2-CAR.IL15 T cells). IL13Rα2-CAR.IL15 T cells recognized glioma cells in an antigen-dependent fashion, had greater proliferative capacity, and produced more cytokines after repeated stimulations in comparison with IL13Rα2-CAR T cells. No autonomous IL13Rα2-CAR.IL15 T-cell proliferation was observed; however, IL15 expression increased IL13Rα2-CAR T-cell viability in the absence of exogenous cytokines or antigen. In vivo, IL13Rα2-CAR.IL15 T cells persisted longer and had greater antiglioma activity than IL13Rα2-CAR T cells, resulting in a survival advantage. Gliomas recurring after 40 days after T-cell injection had downregulated IL13Rα2 expression, indicating that antigen loss variants occur in the setting of improved T-cell persistence. Thus, CAR T cells for GBM should not only be genetically modified to improve their proliferation and persistence, but also to target multiple antigens.Summary: Glioblastoma responds imperfectly to immunotherapy. Transgenic expression of IL15 in T cells expressing CARs improved their proliferative capacity, persistence, and cytokine production. The emergence of antigen loss variants highlights the need to target multiple tumor antigens. Cancer Immunol Res; 5(7); 571-81. ©2017 AACR.

Abstract
10508 Background: Outcome for patients with advanced sarcoma is extremely poor and treatment options are limited. Encouragingly, in our phase 1 dose-escalation trial (Ahmed et al, JCO 2015), systemic administration of up to 1x108/m2 autologous HER2-CAR T cells in patient with HER2+ sarcoma was safe. While T cells did not expand, 4/19 evaluable patients are alive 37-61 months post infusion without evidence of disease. The goal of this study was to evaluate if lympohodepleting chemotherapy can safely induce the expansion of HER2-CAR T cells. Methods: In a phase 1 clinical study, NCT00902044, we administered 1x108/m2 autologous HER2-CAR (with a CD28.zeta signaling domain) T cells to patients with refractory/metastatic HER2+ sarcoma after lymphodepletion. Results: Six patients with refractory/metastatic HER2+ sarcoma (4 osteosarcoma, 1 rhabdomyosarcoma, 1 synovial sarcoma) with a median age of 16 (range: 4 to 55) received up to 3 infusions of 1x108 cells/m2 CAR T cells after lymphodepletion with either fludarabine (Flu; n = 3) or Flu and cyclophosphamide (Flu/Cy; n = 3). Flu and Flu/Cy induced lymphopenia with an absolute lymphocyte count (ALC) of < 100/ml at the day of the T-cell infusion. Only Flu/Cy induced neutropenia (absolute neutrophil count [ANC] < 500/ml) for up to 14 days. 4/6 patients developed grade 1-2 cytokine release syndrome (CRS) within 24 hours of CAR T-cell infusion that resolved completely with supportive care within 3 days of onset. T cells expanded in 5/6 patients (median 89-fold (range: 41 to 2,893) with a median peak expansion on day 7 (range: 5 to 28). CAR T cells could be detected by qPCR in 6/6 patients at 6 weeks post infusion. One patient with rhabdomyosarcoma metastatic to the bone marrow had a complete responses (CR), 2 had stable disease (SD), and 3 had progressive disease (PD). Two patients are alive with a median overall survival of 14.2 months. Conclusions: Infusion of autologous HER2-CAR T cells after lymphodepletion is safe, and can be associated with objective clinical benefit in patients with advanced HER2+ sarcoma. These findings warrant further evaluation in a phase 2b study as a single agent or in combination with other approaches. Clinical trial information: NCT00902044.

Abstract
Peste des petits ruminants (PPR) is an infectious disease caused by peste des petits ruminants virus (PPRV). While PPR mainly affects domestic goats and sheep, it also affects wild ungulates such as ibex, blue sheep, and gazelle, although there are few reports regarding PPRV infection in wild animals. Between January 2015 and February 2015, it was found for the first time that wild ibexes died from PPRV infection in Bazhou, Xinjiang, China, where a total of 38 ibexes (including young and adult ibexes) were found to have died abnormally from PPR-related issues. First, we tested for the presence of the F gene of PPRV by RT-PCR. Then, we compared the sequence of the isolated F gene from the ibex strain, termed PPRV Xinjiang/Ibex/2015, with those previously identified from small domestic ruminants from local areas near where the reported isolate was collected as well as those from other regions. The current sequence was phylogenetically classified as a lineage IV virus, and shared a high level of sequence identity (99.7%) with a previously described Xinjiang PPRV isolate.

Abstract
OBJECTIVE To analyze the expression of leucine-rich and immunoglobulin-like domain gene1 (LRIG1) in pituitary tumor and its clinical significance. PATIENTS AND METHODS Patients were divided into two groups: hypophysoma group (n = 80) and normal group (normal brain tissue, n = 30). The immune tissue chemical streptavidin avidin-peroxidase was applied to detect the expression of LRIG1 of both groups and to analyze its relationship with the patients' prognosis. RESULTS The positive expression rate of LRIG1 in normal brain tissues was significantly higher than that in pituitary adenomas (100% vs. 53.8%) (p < 0.05). The positive expression rate of LRIG1 in pituitary tumors was not significantly related to age and gender, the difference was not statistically significant (p > 0.05). The positive expression rate of LRIGl in non-invasive pituitary adenomas was higher than that in invasive pituitary tumors (68.4% vs. 21.7%), the difference was statistically significant (p < 0.05). Cox multivariate survival analysis showed that LRIG1 can be used as an independent factor for prognosis evaluation. Meier survival analysis showed that the LRIG1 and pituitary tumor types were significantly associated with the prognosis of patients (p < 0.05). CONCLUSIONS LRIG1 was involved in the occurrence and development of pituitary tumor, the expression of LRIG1 can be used as an indicator for prognosis evaluation, and low expression indicated a poor prognosis.

Abstract
In this paper, a two-step AC electrochemical etching process was investigated for the fabrication of platinum probes with controllable aspect ratio from 10 to 30, and tip apex radius less than 300 nm. Experiment results show that the shape of the obtained probes is quite sensitive to the etching time of the first step and the voltage applied in the second step. A graphite crucible was used as the counter electrode during etching. It is proved that the shape of the counter electrode also play a key role for realizing high-aspect-ratio probes. The method presented here provides a simple way in the fabrication of micro-tool for the construction of high-aspect-ratio microstructures, especially for the 3D electrochemical micromachining.

Abstract
The aim of this study was to investigate the role of infiltrating macrophages in renal allograft fibrosis. Forty-six protocol renal allograft biopsies obtained 1 year after transplantation were stained with Sirius red to quantify fibrosis and double stained with CD68 and CD206 to identify the proportion of alternatively activated (M2) macrophages. Biopsies were analyzed for gene expression by microarray, which was correlated with macrophage infiltration and the severity of fibrosis. The number of infiltrating CD68+ cells strongly correlated with the percentage of interstitial fibrosis (r = 0.73, p < 0.0001). Macrophage infiltration at 1 year correlated with renal dysfunction at 1, 12 and 36 months posttransplant (estimated GFR low vs. high: 1 month 78 ± 26 vs. 54 ± 19 mL/min, p < 0.01; 12 months 87 ± 29 vs. 64 ± 19 mL/min, p < 0.05; 36 months 88 ± 33 vs. 60 ± 24 mL/min, p < 0.05). Ninety-two percent of infiltrating macrophages exhibited an M2 phenotype with CD68+ CD206+ dual staining. Gene microarrays demonstrated an alloimmune response with up-regulation of interferon-γ-response genes despite the lack of rejection or inflammatory infiltrate. Consistent with this was the presence of CXCL10 in proximal tubular cells at 3 months. This suggests that M2 macrophage proliferation, or infiltration, was associated with subclinical alloimmune inflammation, tubular injury and progression of fibrosis.
