Abstract
Breast cancer resistance to chemotherapy necessitates novel combination therapeutic approaches. Linc-RoR is a long intergenic noncoding RNA that regulates stem cell differentiation and promotes metastasis and invasion in breast cancer. Herein, we report a dual delivery system employing polyamidoamine dendrimers to co-administer the natural compound curcumin and linc-RoR siRNA for breast cancer treatment. Polyamidoamine dendrimers efficiently encapsulated curcumin and formed complexes with linc-RoR siRNA at an optimal N/P ratio. In MCF-7 breast cancer cells, the dendriplexes were effectively internalized and the combination treatment synergistically enhanced cytotoxicity, arresting the cell cycle at the G1 phase and inducing apoptosis. Linc-RoR gene expression was also significantly downregulated. Individual treatments showed lower efficacy, indicating synergism between components. Mechanistic studies are warranted to define the molecular underpinnings of this synergistic interaction. Our findings suggest dual delivery of linc-RoR siRNA and curcumin via dendrimers merits further exploration as a personalized therapeutic approach for overcoming breast cancer resistance.

Abstract
Natural killer (NK) cells are crucial components of innate immunity, known for their potent tumor surveillance abilities. Chimeric antigen receptors (CARs) have shown promise in cancer targeting, but optimizing CAR designs for NK cell functionality remains challenging. CAR-NK cells have gained attention for their potential to reduce side effects and enable scalable production in cancer immunotherapy. This study aimed to enhance NK cell anti-tumor activity by incorporating PD1-synthetic Notch (synNotch) receptors. A chimeric receptor was designed using UniProt database sequences, and 3D structure models were generated for optimization. Lentiviral transduction was used to introduce PD1-Syn receptors into NK cells. The expression of PD1-Syn receptors on NK cell surfaces was assessed. Engineered NK cells were co-cultured with PDL1+ breast cancer cells to evaluate their cytotoxic activity and ability to produce interleukin-12 (IL-12) and interferon-gamma (IFNγ) upon interaction with the target cells. This study successfully expressed the PD1-Syn receptors on NK cells. CAR-NK cells secreted IL-12 and exhibited target-dependent IFNγ production when engaging PDL1+ cells. Their cytotoxic activity was significantly enhanced in a target-dependent manner. This study demonstrates the potential of synNotch receptor-engineered NK cells in enhancing anti-tumor responses, especially in breast cancer cases with high PDL1 expression.

Abstract
Psoriasis (PS) is characterized by hyperplasia of epidermis and infiltration of immune cells in the dermis. A negligible susceptibility of hypodermic permeation for local anti-inflammatory remedies is one of the major causes of medication failures. Although curcumin (CUR) has indicated effectiveness in treatment of inflammation, its successful permeation through the stratum corneum is yet a challenging issue. Therefore, niosome (NIO) nanoparticles were used as curcumin carriers to enhance its delivery and anti-inflammatory effects. Curcumin-niosome (CUR-NIO) formulations were constructed by the thin-film-hydration (TFH) technique and were added to hyaluronic acid and Marine-collagen gel-based formulation. Five mild-to-moderate PS patients (18-60 years) with PASI scores < 30 with symmetrical and similar lesions were included in the study. The prepared formulation (CUR 15 µM) was topically administered for 4 weeks on the skin lesions, in comparison to the placebo. Clinical skin manifestations were monitored and skin punches were obtained for further gene expression analyses. There was a significant reduction in redness, scaling, and an apparent improvement in CUR-NIO-treated group in comparison to the placebo-treated counterpart. The gene expression analyses resulted in significantly downregulation of IL17, IL23, IL22, and TNFα, S100A7, S100A12, and Ki67 in CUR-NIO-treated lesions. Consequently, CUR-NIO could provide therapeutic approaches for the patients with mild-to-moderate PS by suppressing the IL17/IL23 immunopathogenic axis.

Abstract
AIMS The purpose of this study was to investigate the effect of fermented milk supernatants of autochthonous lactic acid bacteria, including Lactobacillus helveticus KMCH1 (ON561781), Lactococcus lactis KMCM3 (ON561782), and Lactiplantibacillus plantarum KMJC4 (ON615217), on human colon cancer (HT-29) and normal mouse fibroblast (L929) cells in vitro. METHODS AND RESULTS Proteolytic activity, 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium bromide test, evaluation of apoptosis induction, and cell cycle arrest by flow cytometry were the assays performed in this study. The measurement of proteolytic activity of three types of fermented milk supernatant using an orthophthalaldehyde reagent showed that the fermented milk supernatant of L. helveticus KMCH1 included the highest proteolysis. Three types of fermented milk supernatant showed anticancer effects on HT-29 cell in a time- and concentration-based manner (at a concentration of 16 mg ml-1 for 72 h of incubation), while the effect of three types of supernatant on inhibition of L929 cell was 3%-10%. Besides, three types of supernatant inhibited HT-29 cell proliferation by inducing apoptosis and cell cycle arrest in the S phase. CONCLUSIONS Autochthonous lactic acid bacteria strains were able to produce bioactive peptides with anticancer effects in fermented milk. Inhibition of HT-29 cell proliferation was dependent on peptide concentration.

Abstract
BACKGROUND Natural killer (NK) cells, as professional cytotoxic cells, play a key role against cancer in the early and metastatic stages. Their functional defects are highly associated with the initiation or progression of breast cancer (BC). Here, we investigated the phenotypic characterization of NK cells in 26 newly diagnosed BC patients in comparison to 12 healthy counterparts. METHODS Expression of CXCR3 and PD-1, and also NKG2D, and TGF-βRII were studied on CD56dim and CD56bright NK cells from fresh peripheral blood (PB) samples using flow cytometry. The plasma levels of IFN-γ and soluble MIC-A levels were also assessed by ELISA. RESULTS Both CD56dim and CD56bright NK subtypes showed lower CXCR3 and NKG2D expression in BC patients than healthy subjects. Furthermore, patients' CD56bright NK cells significantly showed higher expression levels of TGF-βRII and PD-1. Interestingly, increased concentration of MIC-A level in plasma of BC patients was associated with the higher TGF-βRII and PD-1 expression in all NK cells, while the plasma level of IFN-γ was associated with the lower TGF-βRII expression on CD56bright NK cells in these patients. CONCLUSION Our results demonstrated phenotypically suppressed-NK cells, especially in the CD56bright subset of BC patients. It specifies their potential incompetence and outlines decrement of their anti-tumor activity, which could be interrelated with the tumor pathogenesis, TME immunosuppression, and so disease progression. The induction of compensatory mechanisms revives NK cells function and could be used in combination with the conventional treatments as a putative therapeutic approach for targeted immunotherapy.

Abstract
BACKGROUND Type 2 Diabetes mellitus (T2DM) is one of the most common endocrine diseases that weakens the immune system. Candida albicans, is part of the natural oral flora and increases in cases of compromised immune systems. The exact cause of the increased prevalence of candidiasis in patients with T2DM is still unclear. The study aimed to correlate serum interleukin 10 (IL-10) and interferon-gamma cytokines (IFN-γ) with oral candidiasis in T2DM. METHODS In this case-control study, 81 patients with T2DM and 41 non-diabetic individuals aged 30 to 70 years participated. Demographic information, a Blood sample (for blood glucose and cytokine tests), and an oral cotton swab sample from each individual were obtained. The samples were then incubated in a Sabroud dextrose agar medium. Colony growth was calculated and the type of yeast species in individuals with oral candidiasis was identified by culture in CHROMagar Candida medium. IL-10 and IFN-γ were measured by ELISA kit and the data were analyzed using SPSS-18. RESULTS An overall of 122 participants comprised 73.77% females and 26.22% males. An increase in interleukin-10 by 40% and a decrease in IFN-γ by 6% can increase oral candidiasis prevalence among diabetic patients. Candida albicans was the most prevalent Candida species (spp.) in the diabetic and non-diabetic groups. The presence of oral candidiasis was not associated with HbA1c or FBS levels in both groups. CONCLUSION In the diabetic population, an increase in IL-10 or a decrease in IFN-γ may be associated with an increased risk of oral candidiasis.

Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) as the most prominent type of esophageal cancer (EC) in developing countries encompasses a substantial contribution of cancer-related mortalities and morbidities. Cytotoxic T lymphocytes (CTLs) are the major subset of effector T cells against cancer. However, the microRNAs involved in the development and regulation of CTLs could be disrupted in cancers such as EC. METHODS Here, we evaluated the population of IL-10, TGF-β, IFN-γ, and IL-17a-producing CD3+CD8+ T cells, their association with the circulating levels of miR-21 and miR-29b, and their diagnostic and/or prognostic (after 160 weeks of follow-up) utilities in 34 ESCC patients (12 newly diagnosed: ND, 24 under-treatment: UT) and 34 matched healthy donors. RESULTS The population of IL-10 and TGF-β-producing CTLs (CD8+ Tregs) were considerably expanded, in addition to the overexpression of miR-21 in both groups (ND and UT) of ESCC patients, while the frequency of Tc17 and CD8+ Treg cells increased only in UT patients. The expression means of TGF-β and IL-10 in CTLs were considered to be excellent biomarkers (1 ≥ area under the curve: AUC ≥0.9) in distinguishing ESCC patients and associated subgroups from healthy subjects. Moreover, the lower expressions of TGF-β, IL-17a, IL-10, and IFN-γ in CTLs were associated with ESCC better prognosis. CONCLUSIONS The association between the impaired function of CD3+ CD8+ T cell subsets and miR-21 expression could be introduced as novel therapeutic targets and powerful diagnostic and prognostic markers for ESCC.

Abstract
As the most important innate immune component cancers invader, natural killer (NK) cells have a magnificent role in antitumor immunity without any prior sensitization. Different subsets of NK cells have distinct responses during tumor cell exposure, according to their phenotypes and environments. Their function is induced mainly by the activity of both inhibitory and activating receptors against cancerous cells. Since the immunosuppression in the tumor microenvironment of breast cancer patients has directly deteriorated the phenotype and disturbed the function of NK cells, recruiting compensatory mechanisms indicate promising outcomes for immunotherapeutic approaches. These evidences accentuate the importance of NK cell distinct features in protection against breast tumors. In this review, we discuss the several mechanisms involved in NK cells suppression which consequently promote tumor progression and disease recurrence in patients with breast cancer.

Abstract
Defect in T lymphocyte homeostasis could implicate initiation and development of rheumatoid arthritis (RA). Since PD-1 plays a key role in the regulation of T lymphocytes, its expression pattern in various CD8+ T cell subsets could be so effective in RA pathogenesis. Here, we investigated the expression of PD-1 and CXCR3 on CD8+CD28- T cells in association with the IFN-γ levels in patients with RA. A total of 42 RA patients, including 10 newly-diagnosed (ND) and 32 relapsed (RL) cases and also 20 healthy donors were enrolled. Phenotypic characterization of CD8+ T cells derived from peripheral blood (PB) and synovial fluid (SF) was performed by flow cytometry. The plasma and SF IFN-γ levels were also assessed by ELISA. The frequency of CD8+CD28- T cells showed no significant differences between patients and controls while its higher levels were observed in PB, versus SF of RL patients. Relapsed patients also showed higher CXCR3 and especially PD-1 expression on their CD8+CD28- T cells. The IFN-γ concentration was elevated in SF of ND patients while its plasma level was significantly lower in RL subgroup than controls. Although PD-1 could induce immune suppression in effector T cells, it is upregulated during inflammation and its overexpression on CD8+CD28- T cells within inflammatory synovium is associated with severity of disease in our cohort of RA patients.

Abstract
Several studies have been conducted to find suitable combinations of drugs to increase the efficacy of chemotherapy and reduce the resistance of tumor cells to treatment. Lipopolysaccharide (LPS), as a ligand for Toll-like receptor 4 (TLR-4), can modify immune responses in different cancers. Although multiple studies have been performed in this area, the effect of LPS on tumor cells remains controversial. In the present study, the cytotoxic effects of 5-fluorouracil (5-FU), with or without LPS, were evaluated in human breast cancer cell line (MCF-7) on apoptosis and gene expression in downstream signaling pathways. MCF-7 was obtained from the Pasteur Institute of Iran. The effects of LPS and 5-FU on cytotoxicity, apoptosis, and gene expression in NF-κB, ERK, and AKT signaling pathways were evaluated by MTT assay, Annexin V/propidium iodide (PI) apoptosis assay, and qRT-PCR, respectively. Our findings showed that LPS alone did not significantly affect cytotoxicity or apoptosis, compared to the control cells (untreated cells), while combined with 5-FU, it caused a significant increase in the apoptosis of cancer cells and decreased cell viability. It was also concluded that LPS in combination with 5-FU increased TLR-4 expression and down-regulated gene expression in NF-κB, ERK, and AKT pathways (p=0.001). Although the role of LPS in tumor inhibition or progression remains controversial, our findings suggest that LPS can be considered a novel complementary approach intranslational oncology research of breast cancer therapy.

Abstract
Dysregulation of helper T (Th) cell subsets has been contributed to the initiation and propagation of esophageal squamous cell carcinoma (ESCC). Different microRNAs (miRNAs) have been reported to control the development and functions of tumor-associated immune cells in ESCC. Here, we aimed to assess the IL-10, TGF-β, IFN-γ, and IL-17a-producing CD3+CD8- T cells in association whit miR-21, miR-29b, miR-106a, and miR-155 expression in ESCC patients. A total of 34 ESCC patients including 12 newly diagnosed (ND) and 22 under-treatment (UT) cases and also 34 age-matched healthy donors were enrolled. Flow cytometric characterization of stimulated T cells was performed by staining of the cells with fluorescent conjugated specific anti-human CD3 and CD8 cell surface markers as well as IL-17a, IFN-γ, IL-10, and TGF-β intracytoplasmic cytokines. Circulating RNA was extracted from the plasma, and qRT-PCR was used to evaluate the expression of microRNAs. TGF-β plasma levels were also assessed by ELISA. Results showed that the frequency of Th cells was significantly reduced in patients. A significant increase in Treg as well as Th17 cells population in both patient subgroups was observed. ND patients showed elevated level of Th1 cells and IL-10. However the mean expression of IFN-γ was significantly decreased in Th cells. We also detected higher level of miR-21 in the ESCC patients which was significantly correlated with different subsets of Th cells. Our findings revealed that immune response related to the Th cells is highly impaired in ESCC patients. Association between miR-21 and Th subsets could be correlated with the impairment of anti-tumor immunity and ESCC pathogenesis, which could be potentially used as an important target for immunotherapeutic approaches.

Abstract
BACKGROUND & OBJECTIVE Systemic lupus erythematosus (SLE) is an autoimmune disease with chronic inflammatory immune response. Current therapies mostly rely on glucocorticoids which are accompanied by side-effects and mostly fail to achieve a favorable remission. Th17 subpopulation of T cells is increased in exacerbated SLE as IL-17 cytokine is overexpressed. However, IL-17 is reported to be resistant to glucocorticoids in various disorders. Here, we evaluated the plasma level of IL-17 among newly diagnosed and under-treatment SLE patients to understand the effect of glucocorticoids on Th17 response. METHODS A total of 40 female SLE patients and 20 age- and sex- matched normal subjects were enrolled. IL-17 plasma level was evaluated using ELISA cytokine assay and analyzed with previously obtained IL-10, IFN-γ, and GILZ levels. RESULTS Our findings revealed that IL-17 was overexpressed among under-treatment SLE patients. There was a significant correlation between IL-17 and IFN-γ and significant reverse correlations between IL-17, IL-10, and GILZ levels. IL-17 was not significantly correlated with the disease activity. CONCLUSION According to the role of IL-17 in tissue injury and the fact that glucocorticoids are not successful in preventing organ damages in SLE, the overexpressed IL-17 in response to therapies could be introduced as an underlying reason.

Abstract
Macrophages are versatile phagocytic cells in immune system with immunoregulatory functions. However, the removal of apoptotic cells by macrophages is disturbed in systemic lupus erythematosus (SLE). Aryl hydrocarbon receptor (AhR) is a ligand-activated cytoplasmic receptor and transcription factor with diverse effects on immune response. Indole-3-carbinol (I3C) is an AhR agonist which has been implicated as a beneficial factor in regulating inflammation and cytokine expression in murine models of SLE. However, the molecular mechanisms are not thoroughly studied. Here, we aimed to investigate the ex vivo effects of I3C on polarization of monocyte-derived macrophages (MDMs) in SLE patients and the expression of regulatory cytokines upon AhR activation. MDMs from 15 newly diagnosed SLE patients and 10 normal subjects were induced by Jurkat apoptotic bodies (JABs) and treated with I3C. I3C enhanced the nuclear accumulation of AhR among MDMs of SLE patients and altered the expression of AhR target genes including CYP1A1, IL1- β, IDO-1 and MRC-1. The imbalanced expression of pro- and anti- inflammatory cytokines (IL-10, IL-12, TGFβ1, TNFα, IL-23, IL-6 and IFN-γ) was compensated in response to I3C. AhR activation was also associated with the overexpression of M2 markers (CD163) and downregulation of M1 markers (CD86). Thus, macrophages are activated alternatively in response to I3C. The obtained data indicate that I3C-mediated AhR activation possess immunoregulatory effects on macrophages of SLE patients by exerting an obvious downregulation in the expression of pro-inflammatory and overexpression of anti-inflammatory cytokines. Therefore, AhR could be targeted and further investigated as a choice of anti-inflammatory therapies for autoimmune disorders such as SLE.

Abstract
The anti-inflammatory role of macrophages in apoptotic cells (ACs) clearance is involved in Systemic Lupus Erythematosus (SLE) pathogenesis. The efferocytic capability of macrophages is altered by M1/M2 polarization. Histone deacetylase inhibitors (HDACi) are proposed to enhance the expansion of M2 macrophages. Sodium valproate (VPA) is an HDACi with different anti-inflammatory properties. Here, we aimed to investigate the effects of HDACi by VPA on the polarization of monocyte-derived macrophages (MDMs) and regulating the expression of anti-inflammatory cytokines in SLE. We studied the ex vivo alterations of MDMs among 15 newly diagnosed SLE patients and 10 normal subjects followed by ACs and VPA treatments. M1/M2 polarization was assessed by expression of CD86/CD163, IL1-β, IDO-1, and MRC-1 among treated and non-treated MDMs. We also evaluated the production of IL-10, IL-12, TGF-β1, and TNF-α cytokines in the cell culture supernatants. CD163 was overexpressed upon VPA treatment, while CD86 showed no significant change. IL1-β and IDO-1 genes were significantly downregulated, and the mRNA expression of MRC-1 was increased among VPA-treated MDMs of SLE patients. The anti-inflammatory cytokines (IL-10 and TGF-β1) were overproduced while TNF-α level was decreased in response to VPA. The population of classically activated macrophages was more prevalent among SLE patients and efferocytosis was defected. VPA could successfully enhance the anti-inflammatory immune response through alternative activation of MDMs in SLE patients.

Abstract
The Th17, Th1 and dual Th17/Th1 cells are important players in rheumatoid arthritis (RA) disease. To assess their roles, the frequency and impact of these cells were investigated in patients with different disease activity. In 14 new cases and 41 established RA patients in comparison with 22 healthy controls, the percentages of Th17, Th1 and dual Th17/Th1 cells were determined by flow-cytometry and their correlations were investigated with disease activity score (DAS28). Moreover, serum levels of IL-6 and IL-17 as inducer and functional cytokines for Th17 were investigated. Finally, serum levels of anti citrullinated protein antibody (ACPA) and rheumatoid factor (RF) were assessed. Percentage of Th17 cells in RA patients were increased in comparison with healthy controls (p<0.01). In correlation with this finding, IL-17 and IL-6 cytokines in RA patients also increased (p<0.01). The Th1 cells in RA patients were less than healthy group (p<0.05) and showed negative correlation with disease activity (r=-0.328, p<0.01). Dual Th17/Th1 cell only in new cases of RA were more than healthy control groups (p<0.01). The Th1/Th17 ratio in RA patients is statistically different with healthy control group (p<0.01) and it has negative correlation with disease activity (r=-264, p<0.05). The levels of ACPA and RF were increased with disease progression. Decreasing of Th1/Th17 ratio in RA patient suggested a new paradigm in the field of autoimmune disease and indicated that imbalance or plasticity between these subsets can be important in progress, diagnosis and therapy of RA disease.

Abstract
Macrophages have recently gained attention in systemic lupus erythematosus (SLE) pathogenesis for their role in the anti-inflammatory clearance of apoptotic cells. The M1/M2 polarization of macrophages improves efferocytic capability. Peroxisome proliferator-activated receptor γ is proposed to function in the expansion of the M2 subpopulation. Pioglitazone is a peroxisome proliferator-activated receptor γ agonist with a variety of anti-inflammatory effects. In this paper, we investigated the ex vivo alterations of monocyte-derived macrophages of 15 newly diagnosed SLE patients and 10 normal subjects triggered by apoptotic cells among SLE patients following pioglitazone treatment. The phagocytosis capacity of macrophages and M1/M2 polarization (CD86/CD163) was evaluated. The supernatants were also analyzed for the expression of interleukin (IL)-10, IL-12, transforming growth factor β1 and TNF-α. The mRNA expression of IL-1β and mannose receptor C-type 1 were also quantified among treated and non-treated monocyte-derived macrophages. We found that efferocytosis is defective among monocyte-derived macrophages of SLE patients and might be a major underlying mechanism involved in the sustained inflammation. Pioglitazone could enhance alternative activation of monocyte-derived macrophages and consequently immunomodulation in these patients.

Abstract
Systemic lupus erythematosus (SLE) is an autoimmune disorder in which cytokine balance is disturbed. Glucocorticoids (GCs) are shown to balance immune response by transcriptional regulation of glucocorticoid receptor target genes such as Glucocorticoid-induced leucine zipper (GILZ) which has been introduced as an endogenous anti-inflammatory mediator. In the present study, we assessed the expression of GILZ in association with interferon-γ (IFN-γ), interleukine-10 (IL-10), and B lymphocyte stimulator (BLyS) plasma levels in SLE patients. A total of 40 female patients (18 under treatment and 22 newly diagnosed) were recruited in this study. Real-time RT PCR was conducted to quantify the mRNA expression of GILZ. The plasma levels of IFN-γ, IL-10, and BLyS were evaluated using ELISA method. GILZ was overexpressed among under treatment SLE patients. The mRNA expression of GILZ was significantly correlated with Systemic Lupus Erythematosus Disease Activity Index (SLEDAI) score. IFN-γ and BLyS were downregulated in response to therapies with negative correlations to GILZ. Moreover, IL-10 was upregulated among treated patients. The levels of IFN-γ and BLyS were correlated with the severity of disease, while IL-10 was negatively correlated with SLEDAI score. GILZ could be introduced as one of the acting molecules in mediating the regulatory effects of GCs on producing pro- and anti-inflammatory cytokines in SLE.

Abstract
AbstractBackground:Indoleamine 2, 3-dioxygenase (IDO) is a tryptophan catabolizing enzyme which is involved in immune regulation and autoimmune disorders such as systemic lupus erythematosus (SLE). Interferon-γ (IFN-γ) is an inflammatory cytokine which is the major inducer of IDO expression. Here, we evaluated the level of IFN-γ and IDO among SLE patients in correlation with the severity of SLE.Methods:Fifty-three SLE patients and 35 age matched healthy donors were enrolled in this study. Systemic lupus erythematosus disease activity index (SLEDAI) was used to calculate the disease activity. Real-time RT-PCR and ELISA were used to evaluate the gene expression of IDO and IFN-γ plasma concentration, respectively.Results:We showed that IDO-1, IDO-2 and IFN-γ were overexpressed among SLE patients significantly (p<0.0001). There were significant positive correlations between IFN-γ with the expression of IDO-1 (r=0.722, p<0.0001) and IDO-2 (r=0.682, p<0.0001). There were also positive correlations between SLEDAI scores with IDO-1 (r=0.675, p<0.0001), IDO-2 (r=0.727, p<0.0001) and IFN-γ (r=0.907, p<0.0001).Conclusions:IDO expression and IFN-γ level could be introduced as helpful biomarkers for the determination of disease severity in SLE patients.

Abstract
Hepatitis B virus (HBV) is an etiological agent of viral hepatitis, which may lead to cirrhosis, and hepatocellular carcinoma. Current treatment strategies have not shown promising effect to date but various complications such as, drug toxicity-resistance have been reported. Study on newly discovered compounds, with minimal side effects, as specific HBV inhibitors is a fundamental subject introducing new biologic drugs. Here, we aimed to, by prediction, estimate interactions of HBF-0259 as a non-toxic anti-HBV compound on inhibiting the HBV through either interaction with the viral entry or HBsAg secreting factors using In Silico procedure. Molecular docking was performed by Hex 8.0.0 software to predict the interaction energy (Etot) between HBF-0259 and known cellular factors involved in HBV entry and HBsAg secreting factors. Hex 8.0.0 also employed to create protein-protein complexes. These interactions were then used to analyze the binding site of HBF-0259 within the assumed receptors by MGLTools software. Finally, the amino acid sequences involved in this interaction were aligned for any conservancy. Here, we showed that HBF-0259 Etot with CypA (-545.41 kcal/mol) and SCCA1 (499.68 kcal/mol), involved in HBsAg secretion and HBV integration, respectively, was higher than other interactions. Furthermore, HBF-0259 predicted interaction energy was even higher than those of CypA inhibitors. In addition, we claim that preS1 and/or preS2 regions within HBsAg are not suitable targets for HBF-0259. HBF-0259 has higher interaction energy with CypA and SCCA1, even more than other known receptors, co-receptors, viral ligands, and secretory factors. HBF-0259 could be introduced as potent anti-viral compound in which CypA and or SCCA1, as previously shown, are involved.

Abstract
OBJECTIVES T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignant tumor. Administration of chemical compounds influencing apoptosis and T cell development has been discussed as promising novel therapeutic strategies. Valproic acid (VPA) as a recently emerged anti-neoplastic histone deacetylase (HDAC) inhibitor and pioglitazone (PGZ) as a high-affinity peroxisome proliferator-activated receptor-gamma (PPARγ) agonist have been shown to induce apoptosis and cell cycle arrest in different studies. Here, we aimed to investigate the underlying molecular mechanisms involved in anti-proliferative effects of these compounds on human Jurkat cells. MATERIALS AND METHODS Treated cells were evaluated for cell cycle progression and apoptosis using flowcytometry and MTT viability assay. Real-time RT-PCR was carried out to measure the alterations in key genes associated with cell death and cell cycle arrest. RESULTS Our findings illustrated that both VPA and PGZ can inhibit Jurkat E6.1 cells in vitro after 24 hr; however, PGZ 400 μM presents the most anti-proliferative effect. Interestingly, treated cells have been arrested in G2/M with deregulated cell division cycle 25A (Cdc25A) phosphatase and cyclin-dependent kinase inhibitor 1B (CDKN1B or p27) expression. Expression of cyclin D1 gene was inhibited when DNA synthesis entry was declined. Cell cycle deregulation in PGZ and VPA-exposed cells generated an increase in the proportion of aneuploid cell population, which has not reported before. CONCLUSION These findings define that anti-proliferative effects of PGZ and VPA on Jurkat cell line are mediated by cell cycle deregulation. Thus, we suggest PGZ and VPA may relieve potential therapeutic application against apoptosis-resistant malignancies.

Abstract
Dendritic cells (DCs) are recognized as key regulators of the immune system. Active DC immunization protocols are quickly obtaining interest as an alternative therapeutic approach in acute myeloid leukemia patients. Despite apparent progress in DC-based immunotherapy, some discrepancies were reported in generating potent DCs and their source. In addition to monocytes, DCs can be differentiated from leukemic blasts of acute myeloid leukemia (AML) patients (AML-DC) possessing the ability of stimulating anti-leukemic immune response. In this study, we differentiated peripheral blood blasts of 16 out of 20 AML patients in vitro in the presence of GM-CSF and IL-4 into immature AML-DC. Then, DCs matured using different combinations of Toll-like receptor (TLR) ligands to obtain functional DCs as demonstrated by cell morphology, immunophenotype, and functional activity. Autologous cytotoxic T cell induction of matured DCs was evaluated in four patients and compared with immature counterparts. Our results showed that although the TLR3 agonist (Poly I:C) has a synergistic effect on the TLR4 agonist (lipopolysaccharide, LPS), the addition of the TLR7/8 agonist (R848) is necessary to reinforce the effect of LPS or LPS + POLY(I:C) to produce efficient DCs with the higher level of IL-12 (30 to 90 times). Such DCs activate allogeneic T cells and effectively prime autologous cytotoxic T cells in vitro. In contrast, FSL-1 as a TLR2/6 agonist has a negative effect on LPS + Poly(I:C) and LPS + R848 to produce IL-12. Thus, DCs prepared using a maturation mixture including a TLR7/8 agonist may be used as a potential tool for DC-based immunotherapy purposes in leukemic patients.

Abstract
Infection of human B cells with Epstein-Barr virus (EBV) induces polyclonal activation in almost all infected cells, but a small proportion of infected cells are transformed to immortalized lymphoblastoid cell lines. Since B cells are activated also by CD40 ligand (CD40L) and Toll-like receptor (TLR) agonists via a similar signaling pathway, it is likely that costimulation through these molecules could result in synergistic enhancement of the transformation efficiency of EBV. In this study, the stimulatory effect of TLR7/8 (R848), TLR9 (CpG) agonists and/or CD40L on transformation efficiency of EBV in normal human B cells was assessed using the limiting dilution assay. Costimulation of peripheral blood mononuclear cells (PBMCs) with CpG and R848, but not CD40L, increased significantly the frequency of EBV transformed B cells (p < 0.001). Neither synergistic nor additive effects were observed between TLR agonists and CD40L and also TLR7/8 and TLR9 agonists. Costimulation with R848, CpG and CD40L enhanced the proliferative response of B cells infected with EBV. This effect was more evident when enriched B cells were employed, compared to PBMCs. The promoting effect of TLR agonists stimulation, implies that EBV may take advantage of the genes induced by the TLR stimulation pathway for viral latency and oncogenesis.

Abstract
Little is known regarding the immunobiology of regulatory T (Treg) cells in hematopoietic malignancies, particularly in chronic lymphocytic leukemia (CLL). In the present study, we showed that the frequencies of CD8(+) and CD4(+) Treg cells were significantly increased in progressive as compared with indolent CLL patients and normal subjects. Enriched CD4(+) Treg cells induced a similar level of inhibition in polyclonally activated B cells and effector T cells from CLL patients and normal subjects. Our results suggest that the increase in circulating Treg cells may result in downregulation of tumor-specific immune response, leading to tumor expansion and disease progression.

Abstract
Little is known about the immunobiology of interleukin-17 (IL-17)-producing T cells and regulatory T cells (Treg) in chronic lymphocytic leukemia (CLL). In this study, the frequencies of Th17, Tc17, and CD39(+) Treg cells were enumerated in peripheral T cells isolated from 40 CLL patients and 15 normal subjects by flow cytometry. Our results showed a lower frequency of Th17 and Tc17 cells in progressive (0.99 ± 0.12 % of total CD3(+)CD4(+) cells; 0.44 ± 0.09 % of total CD8(+) cells) compared to indolent patients (1.57 ± 0.24 %, p = 0.042; 0.82 ± 0.2 %, p = 0.09) and normal subjects (1.78 ± 0.2 %, p = 0.003; 0.71 ± 0.09 %, p = 0.04). Decrease in IL-17-producing T cells was associated with CD39(+) Treg cells expansion. Variation of IL-17-producing cells and Treg cells in indolent and progressive patients was neither associated to the expression levels of Th1- and Th2-specific transcription factors T-bet and GATA-3 nor to the frequencies of IFN-γ and IL-4-producing CD4(+) T cells in a selected number of samples. Additionally, suppressive potential of CD4(+) Treg was similar in CLL patients and normal subjects. Our data indicate that progression of CLL is associated with downregulation of IL-17-producing T cells and expansion of Treg cells, implying contribution of these subsets of T cells in the progression of CLL.

Abstract
Leukemic cells from AML patients can be differentiated to dendritic cells (DCs). Such DCs have potential for immunotherapy of patients. Blasts from 15 AML patients were differentiated into DCs and matured by different TLR agonists. We could generate AML-DCs from 73% of patients mostly with M4 or M5 subtypes. The DC recoveries ranged from 28% to 50%. The results showed that concomitant use of TLR4 and TLR7/8 agonists induced proficient DCs. Therefore, a combination of TLR4 and 7/8 agonists can be considered as an appropriate maturation cocktail for AML-DC production in order to use in the immunotherapy of AML patients.

Abstract
BACKGROUND Dysregulation of WNT signaling has been reported in many malignancies. OBJECTIVE This study was conducted to investigate the expression pattern of 14 members of the WNT gene family in different immunophenotypic subtypes of ALL. METHODS Semi-quantitative RT-PCR was performed on samples from 71 ALL patients and 36 age-matched healthy individuals. The ALL patients were categorized into B-ALL (76%), T-ALL (22.6%) and mixed lineage (1.4%) and the B-ALL cases were further classified into pro-B, pre-BI, pre-BII and immature/mature-B based on immuno-phenotypic results. RESULTS Among the WNT genes, WNT-7B (p=0.026), WNT-9A (p=0.020) and WNT-16B (p=0.023) were significantly over-expressed, whereas WNT-2B (p=0.033), WNT-5A (p=0.016), WNT-7A (p<0.0001) and WNT-10A (p<0.0001) were down-regulated in B-ALL. Among the T-ALL subtype, however, significant down-regulation of WNT-2B, WNT-5B, WNT-7A, WNT-10A and WNT-11 was evident. Comparison between B-ALL subtypes showed significant over-expression of WNT-7B, WNT-9A and WNT-5B in certain subtypes. CONCLUSION Our results suggest contribution of the WNT genes in leukemogenesis of ALL.

Abstract
Recent studies have demonstrated expression of Fc receptor-like (FCRL) molecules, a newly identified family with preferential B-cell lineage expression, in some chronic B-cell leukemias with possible implication for classification and/or targeted immunotherapy. In this study, the expression pattern of FCRL1-5 genes was studied in 73 Iranian ALL patients and 35 normal subjects using semi-quantitative RT-PCR method. FCRL protein expression was also investigated by flow cytometry. Our results indicate significant down-regulation of all FCRL genes in ALL compared to normal subjects. Although, FCRL mRNA expression was almost exclusively confined to normal isolated B-cells compared to T-cells, but these genes were similarly expressed in B-ALL, T-ALL and different B-ALL immunophenotypic subtypes. Surface protein expression of FCRL1, 2, 4, and 5 molecules in 10 ALL and 5 normal samples confirmed the PCR results. Expression profile of FCRL molecules in different subtypes of ALL argues against their potential implication as suitable targets for classification and/or immunotherapy of ALL.

Abstract
BACKGROUND Wnt molecules play a key role in growth, proliferation and development of some embryonic and adult organs as well as hematopoietic stem cells. Wnt signaling pathways are aberrantly activated in many tumor types, including solid tumors and hematologic malignancies. OBJECTIVE To investigate the expression profile of a large number of Wnt genes in leukemic cells from Iranian patients with acute myeloblastic leukemia. METHODS RT-PCR method was used to determine the Wnt genes expression in bone marrow (BM) and/or peripheral blood (PB) samples from 16 patients with AML and PB samples of 36 normal subjects. RESULTS Among 14 Wnt molecules included in this study, Wnt-7A and Wnt-10A were significantly down-regulated (p = 0.002 and p < 0.0001, respectively) and Wnt-3 was significantly over-expressed (p < 0.02) in AML patients compared to normal subjects. No significant association was found between Wnt expression and FAB classification of the patients. CONCLUSION Our results demonstrated for the first time aberrant expression of Wnt-7A, Wnt-10A and Wnt-3 genes in Iranian AML patients. This may be of relevance to the tumorigenesis process in this malignancy.
