Abstract
Objective: To elucidate the role of the competitive endogenous RNA (ceRNA) network in immune infiltration of diabetic retinopathy (DR). Methods: We obtained differentially expressed (DE) circRNAs, miRNAs and mRNAs from the Gene Expression Omnibus database. Then, we identified immune infiltration by CIBERSORT and single-sample gene set enrichment analysis and discovered co-expression genes by weighted gene co-expression network analysis. Furthermore, STAT1-mediated Th1 differentiation was determined in DR cell models, DR patients and DR mouse models. Results: hsa_circ_0087100/hsa-miR-6743-5p/STAT1 was involved in immune infiltration of Th1 cells. Aberrant expression of the ceRNA network and STAT1-mediated Th1 differentiation was thus verified in vitro and in vivo. Conclusion: hsa_circ_0087100/hsa-miR-6743-5p/STAT1 may affect Th1 cell differentiation in DR.

The protease inhibitor E64d might attenuate the development of experimental anti-glomerular basement membrane disease through regulating the activation of Th1 cells.

Abstract
BACKGROUND Cathepsins have been recently identified as a regulator in the activation of Th1 and Th17 cells, which play an important role in the pathogenesis of anti-glomerular basement membrane (GBM) disease. Whether cathepsins contribute to the development of anti-GBM disease through regulating the activation of CD4+ T cell is still unclear. METHODS Rats with experimental anti-GBM disease was established by immunization with the nephritogenic T cell epitope α3127-148. E64d, a cysteine cathepsin inhibitor, was administered in vitro and vivo to evaluate the effect of cathepsins on regulating the activation of antigen specific T cells and the development of anti-GBM disease. RESULTS In rats with experimental anti-GBM diseases, E64d treatment not only reduced the levels of proteinuria, serum creatinine and anti-GBM antibody, but also ameliorated the kidney injury with less glomerular IgG deposition, a lower percentage of crescents and less infiltration of CD4+ T cells, CD8+ T cells and macrophages, as well as a lower percentage of splenic Th1 cells. In vitro, E64d treatment could significantly reduce the production of IFN-γ in the supernatant which might be produced by the activation of Th1 cells after being recalled with the autoantigen α3127-148. We also found the CD4+ T cells of rats with anti-GBM disease had an increased expression of cathepsin L (Cts-L), and the percentage of CD4+ T cells with extracellular expression of Cts-L was obviously higher, indicating it as a potential key regulator. CONCLUSIONS E64d might attenuate the development of anti-GBM disease by participating in the activation of Th1 cells, indicating it as a potential drug for anti-GBM disease in the future.

Abstract
The objective was to determine if antigen-specific tissue resident memory T (TRM) cells persist in respiratory tissues of adults immunized as children with whole cell pertussis (wP) or acellular pertussis (aP) vaccines. Mononuclear cells from tonsil or nasal tissue cells were cultured with Bordetella pertussis antigens and TRM cells quantified by flow cytometry. Adults immunized with wP vaccines as children had significantly more IL-17A and IFN-y-producing TRM cells that respond to B. pertussis antigens in respiratory tissues when compared with aP-primed donors. Our findings demonstrate that wP vaccines induce CD4 TRM cells that can persist in respiratory tissues for decades.

Abstract
Systemic lupus erythematosus (SLE) is an inflammatory disorder related to immunity dysfunction. The Th1 cell family including Th1 cells, transcription factor T-bet, and related cytokines IFNγ, TNFα, IL-2, IL-18, TGF-β, and IL-12 have been widely discussed in autoimmunity, such as SLE. In this review, we will comprehensively discuss the expression profile of the Th1 cell family in both SLE patients and animal models and clarify how the family members are involved in lupus development. Interestingly, T-bet-related age-associated B cells (ABCs) and low-dose IL-2 treatment in lupus were emergently discussed as well. Collection of the evidence will better understand the roles of the Th1 cell family in lupus pathogenesis, especially targeting IL-2 in lupus.

Abstract
OBJECTIVES The differentiation of CD4+ T cells is regulated by a complex and fine signaling pathway composed of many molecules during immune response, and the molecular mechanism for regulating T-bet expression is unclear. Mediator complex subunit 1 (Med1) can combine with a variety of co-factors to regulate gene transcription, promote cell proliferation and survival, and affect invariant natural killer T cell (iNKT) development. This study aims to investigate the effect of Med1 on T cell development and CD4+ T cell differentiation in immune response. METHODS Mice with T cell-specific knockout of Med1 gene (Med1F/FCD4cre+, KO) were constructed and verified. The percentage and number of CD4+ and CD8+ T cells in thymus, spleen, and lymph nodes of KO mice and control (Con) mice (Med1F/FCD4cre-) were detected by flow cytometry. After 8 days of infection with lymphocytic choriomeningitis virus (LCMV), the percentage and number of CD4+ T cells or antigen-specific (GP66+) CD4+ T cells, the percentage and number of Th1 cells (Ly6c+PSGL1+) in CD4+ T cells or antigen-specific CD4+ T cells were examined in the spleen of mice. Moreover, the fluorescence intensity of T-bet in CD4+ T cells or antigen-specific CD4+ T cells was analyzed. RESULTS Compared with the Con group, the percentage and number of CD4+ T cells and CD8+ T cells in the thymus, CD4+ T cells in the spleen and lymph nodes of the KO group showed no significant differences (all P>0.05), but the percentage and number of CD8+ T cells in the spleen and lymph nodes of the KO group were diminished significantly (all P<0.05). After 8 days of infection with LCMV, there was no significant difference in the percentage and number of CD4+ T cells or antigen-specific CD4+ T cells in the spleen between the KO group and the Con group (all P>0.05), while in comparison with the Con group, the percentage and number of Th1 cells in CD4+ T cells or antigen-specific CD4+ T cells, and the expression of T-bet in CD4+ T cells or antigen-specific CD4+ T cells were significantly reduced in the spleen of the KO group (all P<0.05). CONCLUSIONS Specific knockout of Med1 in T cells does not affect the development of CD4+ and CD8+ T cells in the thymus, but does affect the maintenance of peripheral CD8+ T cells. In the immune response, Med1 gene deletion affects the expression of transcription factor T-bet, which in turn to reduce Th1 cell differentiation.

Abstract
Lymphedema is a debilitating disease characterized by extremity edema, fibroadipose deposition, impaired lymphangiogenesis, and dysfunctional lymphatics, often with lymphatic injury secondary to the treatment of malignancies. Emerging evidence has shown that immune dysfunction regulated by T cells plays a pivotal role in development of lymphedema. Specifically, Th1, Th2, Treg, and Th17 cells have been identified as critical regulators of pathological changes in lymphedema. In this review, our aim is to provide an overview of the current understanding of the roles of CD4+ T cells, including Th1, Th2, Treg, and Th17 subsets, in the progression of lymphedema and to discuss associated therapies targeting T cell inflammation for management of lymphedema.

Abstract
OBJECTIVE To elucidate the effect of Jiaweidaochi powder on the Th1/Th2 ratio in rats with recurrent aphthous ulcers (RAU). DESIGN 40 Sprague-Dawley rats were included in this study, randomly divided into a control group, a model group, and three treatment groups (0.5 g/ ml, 1 g/ml, 2 g/ml Jiaweidaochi powder). The RAU model of rats was established by autoantigen injection. The effects of Jiaweidaochi powder on the expression of INFG, IL-4, TBX21, and GATA3 mRNA were detected by real-time PCR. The expression of IFN-γ, IL-4, and IFN-γ/IL-4 proteins in oral ulcer tissue and serum of rats were analyzed by Western blot and ELISA, respectively. The proportion of Th1 cells and Th2 cells in RAU rats was analyzed by flow cytometry. RESULTS Jiaweidaochi powder reduced the number, diameter, and duration of oral ulcers in RAU rats. Real-time PCR showed that middle and high-dose Jiaweidaochi powder decreased the expression of INFG TBX21 mRNA and increased the expression of IL-4 and GATA3 mRNA in the oral tissue of RAU rats. ELISA and western blot confirmed that the expression of IFN-γ protein was significantly decreased, and the level of IL-4 protein was increased both in oral tissue and serum of RAU rats treated with middle or high doses of Jiaweidaochi powder. Flow cytometry found that the Jiaweidaochi powder decreased the proportion of Th1 cells and increased the proportion of Th2 cells in RAU rats. CONCLUSION This study found that Jiaweidaochi powder promoted the balance of Th1/Th2 in RAU rats, contributing to the healing of RAU.

Abstract
OBJECTIVE Multiple sclerosis (MS) is a progressing neurodegenerative disease marked by chronic central nervous system inflammation and degeneration.This study investigates gene expression profiles of T-box transcription factor TBX21 (T-bet), interferon-gamma (IFN-γ), and long non-coding RNA MEG3 in peripheral blood mononuclear cells (PBMCs) from treatment-naïve Relapsing-Remitting Multiple Sclerosis patients (RRMS), healthy controls, and RRMS patients on different Disease Modifying Therapies (DMTs). The aim is to understand the role of T-bet, IFN-γ, and MEG3 in MS pathogenesis and their potential as diagnostic and therapeutic targets. RESULTS Elevated T-bet expression is observed in treatment-naïve RRMS patients compared to healthy individuals. RRMS patients treated with Interferon beta-1alpha (IFNβ-1a) and fingolimod exhibit downregulated T-bet and MEG3 expression levels, respectively, with more pronounced effects in females. Healthy individuals show a moderate positive correlation between T-bet and MEG3 and between IFN-γ and T-bet. In RRMS patients treated with Glatiramer Acetate (GA), a strong positive correlation is observed between MEG3 and IFN-γ. Remarkably, RRMS patients treated with Dimethyl Fumarate (DMF) exhibit a significant positive correlation between T-bet and MEG3. These findings underscore the diagnostic potential of T-bet in RRMS, warranting further exploration of MEG3, T-bet, and IFN-γ interplay in RRMS patients.

Abstract
As a pleiotropic cytokine consisting of IL-12p35 and IL-12p40, Interleukin-12 (IL-12) features in inflammation regulation and anti-bacterial immunity. While IL-12 homologs have been identified in non-mammalian species, the precise mechanisms by which IL-12 contributes to early adaptive immune responses in vertebrates remain incompletely understood. Herein, an evolutionary conserved Oreochromis niloticus IL-12 (defined as OnIL-12) was identified by synteny characterization, structural comparisons and phylogenetic pattern of IL-12p35b and IL-12p40a. IL-12p35b and IL-12p40a exhibited widespread expression in lymphoid-related tissues of tilapia, while their mRNA expression in head-kidney demonstrated a significant increase after Edwardsiella piscicida infection. Compared with other lymphocytes, recombinant OnIL-12 (rOnIL-12) displayed stronger affinity binding to T cells. Although stimulation of lymphocytes with the p35b or p40a subunit resulted in a significant induction of IFN-γ expression, rOnIL-12 showed stronger potential to promote IFN-γ expression than these subunits. rOnIL-12 not only elevated the mRNA expression level Th1 cell-associated transcription factor T-bet in lymphocytes, but also increased the proportion of CD4-1+IFN-γ+ lymphocytes. Moreover, the mRNA and phosphorylation levels of STAT1, STAT3, STAT4 and STAT5 were enhanced by rOnIL-12. These findings will offer previous evidence for further exploration into the regulatory mechanisms of Th1 cellular immunity in early vertebrates.

BACKGROUND Orthotopic liver transplantation is the only option for patients with end-stage liver disease and hepatocellular carcinoma. Post-transplant immunosuppressive therapy is important to prevent graft failure. We investigated the effectiveness of tacrolimus (FK506) and their mechanisms for liver transplant immune tolerance in an outbred rat LT model. RESULTS To investigate the therapeutic effect of the FK506 on outbred rat LT model, FK506 and postoperative therapy were administered subcutaneously once or twice daily to transplanted rats. Histopathological and immunohistochemical analyses were conducted for all groups. The regulation of inflammatory cytokine signaling in the spleen was analyzed by flow cytometry. FK506 attenuated allograft rejection and increased survival in rat orthotopic liver transplantation models. The FK506-treated group had reduced serum levels of alanine aminotransferase, aspartate aminotransferase and alkaline phosphatase. Furthermore, FK506 decreased the expression of inflammatory cytokines and the activation of pathogenic Th1 and Th17 cells in the liver. CONCLUSIONS Taken together, we revealed that FK506 ameliorated strong allograft rejection in outbred liver transplantation model by anti-inflammatory effect and inhibitory peroperty of pathogenic T cells.

Abstract
Neoadjuvant chemoradiotherapy (NCRT) followed by surgery is recommended for locally advanced esophageal squamous cell carcinoma (ESCC) treatment. Patients who achieve a pathological complete response (pCR) have better survival. Our study aimed to discover immune-associated predictors of pCR in ESCC. Herein, we found that Th1-cell infiltration inferred from RNA sequencing was higher in the pCR group than in the non-pCR group. Multiplexed immunohistochemistry (mIHC) confirmed that Th1-, CD8+ T-, NK-, NKT-, and dendritic-cell infiltration was positively associated with pCR. The spatial relationships between Th1 cells and CD8+ T, NK, NKT, dendritic, or ESCC cells were significant pCR predictors. The active and desert subtypes were identified based on immune cell infiltration, and showed different pCR rates. In vitro experiments confirmed that Th1 cells inhibited the proliferation and improved the chemosensitivity and radiosensitivity of ESCC cells. Th1 cells upregulated interferon-gamma response signaling and antigen presentation pathways and downregulated lipid metabolism and MAPK pathways of ESCC cells. These findings highlight the important role of Th1 cells as the predictor of pCR and the regulator of chemosensitivity and radiosensitivity of ESCC, and suggest elevating Th1-infiltration as a strategy to improve NCRT response.

Abstract
BACKGROUND Conivaptan, a nonselective antagonist of vasopressin receptors V1a and V2, is the first drug of this class to be used for treating euvolemic and hypervolemic hyponatremia. Recently, increasing evidence supports the involvement of vasopressin in immune responses. AIMS In this study, we investigated the effect of conivaptan on the modulation of CD4+ T cell homeostasis and the progression of experimental colitis. METHODS The expression of the V1a receptor on CD4+ T cells was detected by immunofluorescence and western blot. The subset of isolated CD4+ T cells were examined after arginine vasopressin (AVP) incubation. CD4+ T cells were injected into DNBS-induced mice through the tail vein. The severity of colitis was evaluated according to weight, disease activity index (DAI), and morphological injury. Intracellular Ca2+ ([Ca2+]i) signaling in CD4+ T cells was measured using the Fluo-3 AM loading method. T-bet and IFN-γ mRNAs in the colon were detected by real-time polymerase chain reaction (qPCR). RESULTS We found that CD4+ T cells expressed the V1a receptor. Activation of the V1a receptor significantly promoted the differentiation of CD4+ T cells into T helper 1 (Th1) cells. This process was blocked by conivaptan treatment. However, the activation of the V1a receptor did not evoke an increase in [Ca2+]i in CD4+ T cells. Notably, conivaptan markedly alleviated body weight loss, pathological damage, and expression of T-bet and IFN-γ in the colon of DNBS-treated mice. CONCLUSIONS For the first time, we report that conivaptan attenuated colitis by inhibiting the differentiation of CD4+ T cells into Th1 cells. Mechanistically, the anti-inflammatory role of conivaptan is independent of [Ca2+]i.

Abstract
Background: Recent studies have reported a wide spectrum of ocular surface injuries in the context of autoimmune reactions in Graves' orbitopathy (GO). Increased expression of inflammatory mediators in tears of GO patients suggests that the lacrimal glands could be a target for immune responses. However, the immunophenotype for GO lacrimal microenvironment is not known. This study aimed to elucidate the pathological changes of GO lacrimal glands. Methods: In this case-control study, lacrimal glands were surgically collected from GO patients who underwent orbital decompression surgery and control subjects who underwent other ocular-related surgery. Bulk RNA-sequencing, flow cytometry with dimensional reduction, and immunohistochemical and multiplexed stainings were conducted. Western blotting and multipathway assays were performed in CD34+ fibroblasts derived from lacrimal and orbital tissues. Results: Increased expression of cytokines and chemokines accompanied by a variety of immune cell infiltrations mainly involving T cells, B cells, and monocytes was found in GO lacrimal glands. An in-depth investigation into T cell subsets revealed interferon (IFN)-γ-producing T helper (Th)1 and interleukin (IL)-17A-producing Th17 cell-dominated autoimmunity in the active GO lacrimal microenvironment. Both fibrosis and adipogenesis were observed in GO lacrimal tissue remodeling. IL-17A, not IFN-γ, stimulated transforming growth factor-β-initiated myofibroblast differentiation as well as 15-deoxy-Δ12,14-prostaglandin J2-initiated adipocyte differentiation in CD34+ lacrimal fibroblasts (LFs) and orbital fibroblasts (OFs), respectively. IL-17A activated many fibrotic and adipogenic-related signaling pathways in CD34+ LFs and OFs. A novel anti-IL-17A monoclonal antibody SHR-1314 could reverse the promoting effect of IL-17A on fibrosis and adipogenesis in CD34+ LFs and OFs. Conclusions: Our findings provide evidence for the infiltration of different lymphocytes into GO lacrimal microenvironment, where Th1 and Th17 cells characterize the onset of active lacrimal inflammation and contribute to tissue remodeling. These findings may have potential future therapeutic implications regarding the utility of anti-IL-17A therapy, which should be studied in future research.

Abstract
BACKGROUND Insulitis is defined by the presence of immune cells infiltrating in the pancreatic islets that might progress into the complete β-cell loss. The immunomodulatory properties of bone marrow-derived mesenchymal stem cells (BM-MSCs) have attracted much attention. This study aimed to evaluate the possible immunomodulatory effects of rat BM-MSCs and MSCs-derived insulin-producing cells (IPCs) in a mouse model of pancreatic insulitis. METHODS Insulitis was induced in BALB/c mice using five consecutive doses of streptozotocin. MSCs or IPCs were directly injected into the pancreas of mice and their effects on the expression of Th subsets-related genes were evaluated. RESULTS Both BM-MSCs and IPCs significantly reduced the expression of pancreatic Th1-related IFN-γ (P < 0.001 and P < 0.05, respectively) and T-bet genes (both P < 0.001). Moreover, the expression of IL-10 gene was significantly increased in IPC-treated compared to BM-MSC- or PBS-treated mice (P < 0.001 both comparisons). CONCLUSIONS BM-MSCs and IPCs could successfully suppress pathologic Th1 immune responses in the mouse model of insulitis. However, the marked increase in IL-10 gene expression by IPCs compared to BM-MSCs suggests that their simultaneous use at the initial phase of autoimmune diabetes might be a better option to reduce inflammation but these results need to be verified by further experiments.

Abstract
Investigation of cancer as a cell-level disease has led to the development of cancer cell-directed therapies including cytotoxic T lymphocyte (CTL)-based immunotherapy; yet, many patients are refractory to these modalities of cancer treatment and acquired resistance frequently occurs. Of note, cancer environment controls the manifestation of cancerous cell phenotype. Helper T (Th) cells orchestrate immune defense responses targeting cancer cells as well as the tumor microenvironment. Recent studies have shown that in addition to interferon (IFN)-γ-producing Th1 cells, interleukin (IL)-4-producing Th2 cells function as potent anticancer effectors in part by promoting tumor stroma reconfiguration and tumor tissue repair. Such Th cell-mediated tissue-level immunity may be harnessed for novel modalities of cancer environment immunotherapy.

Abstract
OX40 is one of the co-stimulatory molecules expressed on T cells, and it is engaged by OX40L, primarily expressed on professional antigen-presenting cells such as dendritic cells. The OX40L-OX40 axis is involved in the sustained activation and expansion of effector T and effector memory T cells, but it is not active in naïve and resting memory T cells. Ligation of OX40 by OX40L accelerates both T helper 1 (Th1) and T helper 2 (Th2) effector cell differentiation. Recent therapeutic success in clinical trials highlights the importance of the OX40L-OX40 axis as a promising target for the treatment of atopic dermatitis.

Abstract
Background Acute liver injury (ALI) is a severe liver disease. Chitinase 3-like-1 (CHI3L1), a protein belonging to the glycosyl hydrolase family 18, is involved in many diseases, such as inflammatory diseases, bacterial infections, and various malignant tumors; however, the function of CHI3L1 in ALI remains unclear. The objective of this study was to evaluate the protective functions of CHI3L1 against thioacetamide (TAA)-induced ALI in mice and explore its potential mechanisms. Methods Data from 20 patients with ALI and 10 healthy subjects was collected. Serum CHI3L1, serum aspartate transaminase (AST), and serum alanine aminotransferase (ALT) were measured. To establish ALI mouse models, thioacetamide was intraperitoneally injected into groups of the CHI3L1-knockout (CHI3L1-KO) and wild-type (WT) mice (80 and 150 mg/kg). Recombinant CHI3L1 protein (rCHI3L1) (5 µg/kg), IFN-γ (500 ng), and WP1033 (an inhibitor of P-STAT3, 0.2 mL) were injected before TAA treatment, after which the effects were estimated. Splenic CD4+CD62L+ naive T cells were isolated from CHI3L1-KO mice and stimulated to differentiate into regulatory T (Treg) cells, T-helper 1 (Th1) cells, T-helper 2 (Th2) cells, and T-helper 17 (Th17) cells. Results Increased serum CHI3L1 levels were seen both in healthy subjects and post-therapy patients compared with ALI patients. CHI3L1 levels were negatively correlated with serum ALT and AST levels in ALI patients. CHI3L1-KO group showed higher serum ALT and AST levels than the WT group following TAA treatment, while tail vein injection of rCHI3L1 reduced liver tissue injury and improved Treg cell differentiation in vivo. In vitro experiment showed that knockout of CHI3L1 improved IFN-γ+ Th1 cell differentiation. Furthermore, intraperitoneal administration of IFN-γ produced more severe hepatocellular necrosis compared with rCHI3L1 injection alone. Mechanism study showed that T-box expressed in T cells (T-bet), and signal transducer and activator of transcription 3 (STAT3), play a critical role in adversely mediating the effect of CHI3L1, which is consistent with the finding that treatment with WP1033 down-regulated the differentiation of the Th1 cells in vitro and reduced severity of liver injury in vivo. Conclusions CHI3L1 reduced the production of IFN-γ and inhibited Th1 cell differentiation through the STAT3 signaling pathway, which could be a potential therapeutic strategy for treating ALI.

Abstract
Helicobacter pylori infection induces CD4+ T differentiation cells into IFN-γ-producing Th1 cells. However, the details of mechanism underlying this process remain unclear. Notch signal pathway has been reported to regulate the differentiation of CD4+ T cells into Th1 subtype in many Th1-mediated inflammatory disorders but not yet in H. pylori infection. In the present study, the mRNA expression pattern of CD4+ T cells in H. pylori-infected patients differed from that of healthy control using Human Signal Transduction Pathway Finder RT2 Profiler PCR Array, and this alteration was associated with Notch signal pathway, as analyzed by Bioinformation. Quantitative real-time PCR showed that the mRNA expression of Notch1 and its target gene Hes-1 in CD4+ T cells of H. pylori-infected individuals increased compared with the healthy controls. In addition, the mRNA expression of Th1 master transcription factor T-bet and Th1 signature cytokine IFN-γ was both upregulated in H. pylori-infected individuals and positively correlated with Notch1 expression. The increased protein level of Notch1 and IFN-γ were also observed in H. pylori-infected individuals confirmed by flow cytometry and ELISA. In vitro, inhibition of Notch signaling decreased the mRNA expression of Notch1, Hes-1, T-bet, and IFN-γ, and reduced the protein levels of Notch1 and IFN-γ and the secretion of IFN-γ in CD4+ T cells stimulated by H. pylori. Collectively, this is the first evidence that Notch1 is upregulated and involved in the differentiation of Th1 cells during H. pylori infection, which will facilitate exploiting Notch1 as a therapeutic target for the control of H. pylori infection.

Abstract
Psoriasis is a debilitating chronic skin disease with a worldwide prevalence. Its main features include well-marked silvery scales on the skin of hands and feet and back which arise due to hyperproliferation of keratinocytes and infiltration of immune cells in the skin. Multiple interactions exist between adaptive immune cells such as T cells and innate immune cells such as neutrophils and macrophages which are key players in the pathogenesis of psoriasis. Interleukin-2-inducible T-cell kinase (ITK) plays a key role in Th17 cell development through control of several transcription factors. ITK has been shown to control NFATc1, NFkB and STAT3 in CD4+ T cells. Effect of ITK inhibitor in imiquimod (IMQ)-induced psoriasiform inflammation remains to be explored. In the current examination, role of ITK signaling and its inhibition blockade were evaluated on NFATc1, NFkB and STAT3, IL-17A, TNF-α, IFN-γ, Foxp3, IL-10 in CD4+ T cells in IMQ model. Our data display that ITK signaling is involved in IMQ-induced psoriatic inflammation as paralleled by enhancement of p-ITK, NFATc1, p-NFkB and p-STAT3 in CD4+ T cells. It was associated with enhancement of Th17/Th1 cells and neutrophilic inflammation in the skin. Preventive treatment with ITK inhibitor led to a reduction in Th17/Th1 cells and enhancement of Treg cells. Overall, this study suggests that ITK signaling is an important modulator of transcription factor signaling in CD4+ T cells which is associated with Th17/Th1 cells and psoriasiform inflammation in mice. ITK signaling blockade could be a therapeutic target for the treatment of psoriatic inflammation.

Abstract
During pregnancy, various immune effectors and molecules participating in the immune-microenvironment establish specific maternal tolerance toward the semi-allogeneic fetus. Activated maternal immune effectors by the trophoblast antigens, such as T helper (Th), T cytotoxic (Tc), T regulatory (Treg), and B cells, are involved in the regulation of adaptive immunity. Recognition of active signal through the T cell receptors stimulate the differentiation of naive CD3+CD4+ T cells into specific T cell subsets, such as Th1, Th2, Th9, Th17, Th22, and follicular Th cells (Tfh). Each of these subsets has a significant and distinct role in human pregnancy. Th1 immunity, characterized by immune-inflammatory responses, becomes dominant during the peri-implantation period, and the “controlled” Th1 immunity benefits the invading trophoblasts rather than harm. Quickly after the placental implantation, the early inflammatory Th1 immunity is shifted to the Th2 anti-inflammatory immune responses. The predominant Th2 immunity, which overrules the Th1 immunity at the placental implantation site, protects a fetus by balancing Th1 immunity and accommodate fetal and placental development. Moreover, Treg and Th9 cells regulate local inflammatory immune responses, potentially detrimental to the fetus. Th17 cells induce protective immunity against extracellular microbes during pregnancy. However, excessive Th17 immunity may induce uncontrolled neutrophil infiltration at the maternal-fetal interface. Other Th cell subsets such as Tfh cells, also contribute to pregnancy by setting up favorable humoral immunity during pregnancy. However, dysregulation of Th cell immunity during pregnancy may result in obstetrical complications, such as recurrent pregnancy losses (RPL) and preeclampsia (PE). With this review, we intend to deliver a comprehensive overview of CD4+ Th cell subsets, including Th1, Th2, Th9, Th17, Th22, and Tfh cells, in human pregnancy by reviewing their roles in normal and pathological pregnancies.

Abstract
Multiple sclerosis (MS) is a chronic autoimmune disease characterized by inflammatory infiltration and demyelination in the central nervous system (CNS). Among the factors involved in the immunological mechanisms of MS, T helper 1 (Th1) cells and T helper 17 (Th17) cells play a critical role. Compound 21, a novel phloroglucinol derivative, significantly protected myelin from damage in our previous study. However, it remains unclear whether this compound affects MS. In this study, the experimental autoimmune encephalomyelitis (EAE) rat model was established to mimic the pathological process of MS and evaluate the neuroprotective effect of Compound 21. The results illustrated that Compound 21 treatment notably attenuates neurological deficits, immune infiltration, and demyelination in EAE rats. Our mechanistic investigation revealed that Compound 21 treatment reduces the population of Th1/Th17 cells and inhibits their infiltration into the CNS. Furthermore, we found that the inhibition of Th1/Th17 cell infiltration is related to the direct suppression of Th1/Th17 cell differentiation and the inhibition of proinflammatory microglial cells. Collectively, these results confirm that Compound 21 suppresses infiltrated Th1/Th17 cells to alleviate demyelination in EAE rats, suggesting its potential role as a novel candidate for MS treatment.

Abstract
Immune thrombocytopenia (ITP) is an autoimmune disorder characterized by low platelet counts due to enhanced platelet clearance and compromised production. Traditionally, ITP was regarded a B cell mediated disorder as anti-platelet antibodies are detected in most patients. The very nature of self-antigens, evident processes of isotype switching and the affinity maturation of anti-platelet antibodies indicate that B cells in order to mount anti-platelet immune response require assistance of auto-reactive CD4+ T cells. For a long time, ITP pathogenesis has been exclusively reviewed through the prism of the disturbed balance between Th1 and Th2 subsets of CD4+ T cells, however, more recently new subsets of these cells have been described including Th17, Th9, Th22, T follicular helper and regulatory T cells. In this paper, we review the current understanding of the role and immunological mechanisms by which CD4+ T cells contribute to the pathogenesis of ITP.

Abstract
PURPOSE A small molecular compound, aminooxy-acetic acid (AOA), has been shown to modulate experimental autoimmune encephalomyelitis (EAE). The current study was designed to investigate whether AOA has a similar effect on the development of experimental autoimmune uveitis (EAU) and to further explore underlying mechanisms of this drug. METHODS EAU was induced in C57BL/6J mice by immunization with interphotoreceptor retinoid-binding protein peptide 651-670 (IRBP 651-670). AOA (500μg or 750μg) or vehicle was administered by intraperitoneal injection from day 10 to 14 after EAU induction. The severity was assessed by clinical and histological scores. The integrity of the blood retinal barrier was detected with Evans Blue. Frequencies of splenic Th1, Th17 and Foxp3+ Treg cells were examined by flow cytometry. The production of cytokines was tested by ELISA. The mRNA expression of IL-17, IFN-γ and IL-10 was detected by RT-PCR. The expression of p-Stat1 and NF-κB was detected by Western Blotting. RESULTS AOA was found to markedly inhibit the severity of EAU, as determined by clinical and histopathological examinations. AOA can relieve the leakage of blood retinal barrier (BRB). Functional studies found a decreased frequency of Th1 and Th17 cells and an increased frequency of Treg cells in EAU mice as compared with controls. Further studies showed that AOA not only downregulated the production of the proinflammatory cytokines including IFN-γ and IL-17 but also upregulated the expression of an anti-inflammatory cytokine such as IL-10, which might be caused by inhibiting the expressions of p-Stat1 and NF-κB. CONCLUSION This study shows that AOA inhibits the severity and development of EAU by modulating the balance between regulatory and pathogenic lymphocyte subsets.

Abstract
Acquired Factor VIII inhibitor is a rare acquired clotting disorder which has been seen in the setting of particular medications, autoimmune disease, and malignancy. Reports of this disorder in patients receiving immunomodulatory therapies for multiple sclerosis are rare. We present a case of a 48 year-old woman with likely development of acquired Factor VIII inhibitor in the setting of interferon beta monotherapy for multiple sclerosis, and discuss the pathogenesis of this disorder which involves shifts in helper T cell populations and increased production of immunoglobulins.

Abstract
The effects of maternal vitamin D status on offspring's Th1/Th2 cell function and the related mechanisms have not been reported. In this study, we established the rat model of vitamin D deficiency during pregnancy. 48 female Sprague-Dawley rats (8 weeks old) were randomly assigned to three groups (n = 16/group): control group (fed with standard AIN-93 G diet until parturition), vitamin D deficiency group (VDD group, fed with vitamin D deficient diet until parturition) and vitamin D supplementation group (VDS group, fed with vitamin D deficient diet prior to mating and with standard AIN-93 G diet during pregnancy). At 4 weeks of age, the ratio of T helper type 1/ T helper type 2 (Th1/Th2) cells and the levels of Th1/Th2 cytokines (IFN-γ, IL-4, IL-5, IL-6, IL-10 and IL-13) in offspring rats were determined by Flow Cytometry and Meso Scale Discovery, respectively. Furthermore, DNA methyltransferase (DNMT) activity as well as the methylation levels of IFN-γ and IL-4 genes were measured. As a result, rats in the VDD group showed a significant decrease in Th1/Th2 ratio and IFN-γ level and an increase in IL-4 level. Additionally, up-regulated DNMT activity and increased methylation rate of IFN-γ gene was shown in VDD offspring rats. Supplementation with vitamin D during pregnancy reversed the above abnormalities. In conclusion, maternal vitamin D deficiency affected the function of Th1/Th2 cells and methylation of IFN-γ gene in offspring rats. Meanwhile, maternal vitamin D deficiency had the potential to regulate DNMT activity, which may determine the status of methylation.

Abstract
A flavonoid Astragalin (kaempferol-3-O-β-d-glucopyranoside, Ast) has several biological activities including anti-oxidant, anti-HIV, and anti-allergic effects. Nonetheless, its insolubility in hydrophilic solvents imposes restrictions on its therapeutic applications. In this study, we investigated the effects of water-soluble astragalin-galactoside (kaempferol-3-O-β-d-isomaltotrioside, Ast-Gal) on murine bone marrow-derived dendritic cell (DC) maturation and T helper (Th) cell-mediated immune responses. Ast-Gal significantly increased maturation and activation of DCs through the upregulation of surface markers, such as cluster of differentiation (CD)80, CD86, and Major histocompatibility complex (MHC) II in a dose-dependent manner, while Ast had little effects. Additionally, Ast-Gal-treated DCs markedly secreted immune-stimulating cytokines such as interleukin (IL)-1β, IL-6, and IL-12. Importantly, Ast-Gal strongly increased expression of IL-12, a polarizing cytokine of Th1 cells. In a co-culture system of DCs and CD4+ T cells, Ast-Gal-treated DCs preferentially differentiates naïve CD4+ T cells into Th1 cells. The addition of neutralizing IL-12 monoclonal antibody (mAb) to cultures of Ast-Gal-treated DCs and CD4+ T cells significantly decreased interferon (IFN)-γ production, thereby indicating that Ast-Gal-stimulated DCs enhance the Th1 response through IL-12 production by DCs. Injection with Ast-Gal-treated DCs in mice increased IFN-γ-secreting Th1 cell population. Collectively, these findings indicate that hydrophilically modified astragalin can enhance Th1-mediated immune responses via DCs and point to a possible application of water-soluble astragalin-galactoside as an immune adjuvant.

Abstract
OBJECTIVE The objective of this study is to investigate the role of cathepsin H (CatH), a lysosomal cysteine protease, in the development of experimental autoimmune encephalomyelitis (EAE), an animal model of multiple sclerosis. METHODS EAE was induced in CatH-deficient mice (CatH-/-) and wild-type littermates (+/+) using myelin oligodendrocyte glycoprotein (MOG) 35-55. The effects of CatH deficiency were determined by clinical scoring, mRNA expression levels of Tbx21, Rorc and FoxP3, protein levels of poly(I:C)-induced toll-like receptor 3 (TLR3) and phosphorylation of IRF3, and secretion of interferon-β (IFN-β) by splenocytes. RESULTS AND CONCLUSIONS CatH-/- showed a significantly earlier disease onset of EAE and increased Th1 cell differentiation in splenocytes. Splenocytes prepared from immunized CatH-/- showed a significant decrease in poly(I:C)-induced increased TLR3 expression, interferon regulatory factor 3 (IRF3) phospholylation and IFN-β secretion. Therefore, CatH deficiency impaired TLR3-mediated activation of IRF3 and consequent secretion of IFN-β from dendritic cells, leading to the enhancement of Th1 cell differentiation and consequent early disease onset of EAE.

Abstract
AIM To characterize the roles of VvhA in host's acquired immune response to Vibrio vulnificus infection. MATERIALS & METHODS The recombinant VvhA fusion protein was used to immunize mice and the anti-VvhA polyclonal antibody was produced in vivo for prophylactic and therapeutic efficacy assay. The roles of VvhA in T helper (Th) cells differentiation were analyzed by vvhA-deleted mutant during the early phase of infection, while the ratio of Th2 and T follicular helper (Tfh) cells were examined in VvhA immunization. RESULTS Anti-VvhA antibody exhibited neutralization activity against V. vulnificus. Wild-type strain induced higher level of Th1 cells than the mutant, and the concentrations of IgG2a and IFN-γ were increased during the early phase of infection. The spontaneous development of Tfh was observed in immunized model, and the serum IL-21 was increased. CONCLUSION V. vulnificus VvhA elicited cellular and humoral immune responses by Th1 and Tfh cells to provide protection against VvhA.

Abstract
BACKGROUND Chronic hepatitis B (CHB) is one of the major infectious diseases in which CD4+ T helper (Th) cells play a crucial role. Th9 cells are a distinct subset of CD4+ Th cells with important physiological functions. OBJECTIVE The study aimed to assess the potential involvement of Th9 cells in the inadequate immune response leading to chronic HBV infection. PATIENTS AND METHODS Peripheral blood samples were collected from 22 CHB patients and 16 healthy controls (HC). The frequencies of circulating Th9, Tc9, Th1, and Tc1 cells were determined by flow cytometry. Serum levels of IL-9 and IL-10 were analyzed by ELISA. Serum biochemical indices of liver function were measured using an automated analyzers. Serum HBV DNA loads were analyzed by real-time PCR. The potential association of the frequency of Th9, Tc9, Th1 or Tc1 cells with clinical parameters was assessed. RESULTS The frequency of circulating Th9 cells was significantly lower in CHB patients than those in HC. However, no significant differences in the frequency of Tc9, Th1 or Tc1 cells were observed between the two groups. The percentages of Th9 cells, but not Tc9 cells, were negatively correlated with HBV DNA loads, whereas the percentages of Tc1 cells were positively correlated with viral loads in CHB patients. Moreover, there was a positive correlation between serum levels of IL-9 and IL-10 and HBV DNA loads in patients with chronic HBV infection. CONCLUSION The depletion of Th9 cells is associated with the development of chronic HBV infection.

Abstract
Cytokine-mediated immunity plays a dominant role in the pathogenesis of various immune diseases, including asthma. The recent identification of the family interleukin (IL)-1-related cytokine IL-18 now contributes to our understanding of the fine-tuning of cellular immunity. IL-18 can act as a cofactor for Th2 cell development and IgE production and also plays an important role in the differentiation of Th1 cells. Recent work identified an IL-18 association with the pathogenesis of asthma, wherein increased IL-18 expression was found in the serum of patients. Furthermore, IL-18 polymorphisms with susceptibility to asthma were reported, suggesting that IL-18 may be therapeutically relevant to asthma. In this review, we discuss the role of IL-18 in the pathogenesis of asthma and its therapeutic potential based on current research.

Abstract
Background This study explored the details of the immune response after autologous hematopoietic stem cell transplantation (AHSCT) treatment in type 1 diabetes mellitus. Methods Peripheral blood mononuclear cells (PBMCs) from 18 patients with type 1 diabetes mellitus were taken at baseline and 12 months after AHSCT or insulin-only therapy. The lymphocyte proliferation, mRNA expression and secretion of pro-inflammatory and anti-inflammatory cytokines belonging to T-helper type 1 (Th1), T-helper type 17 (Th17) and regulatory T (Treg) cells in PBMC culture supernatants were assessed. Results Compared with patients receiving insulin-only treatment, the patients receiving AHSCT treatment showed better residual C-peptide secretion, lower anti-GAD titers and less exogenous insulin dosages after 12 months of follow-up. AHSCT treatment was associated with significantly reduced Th1 and Th17 cell proportions as well as decreased IFN-γ, IL-2, IL-12p40 and IL-17A levels in the PBMC culture supernatants (all P < 0.05). Although there was no significant Treg cell expansion after AHSCT treatment, we observed increased IL-10, TGF-β and Foxp3 mRNA expression and increased TGF-β levels. However, we found no significant changes in the T-cell subpopulations after insulin treatment, except for higher IL-12p40 mRNA expression and a lower proportion of Treg cells. Conclusions AHSCT treatment was associated with decreased expansion and function of Th1 and Th17 cells, which may explain the better therapeutic effect of AHSCT compared with the traditional intensive insulin therapy.

Abstract
BACKGROUND Th17/Treg imbalance and the levels of related cytokines are essential in the pathogenesis of autoimmune and infectious diseases. The aim of the current study was to assess the Treg/Th17 balance and the levels of related cytokines associated with various degrees of liver injury in patients with chronic hepatitis B virus (HBV) infection. METHODS The proportions of peripheral Th17, Treg and Th1 cells in 7 patients classified as asymptomatic hepatitis B virus carriers (AsCs), 38 patients with low or moderate grade chronic hepatitis B (CHB-LM), 20 patients with chronic severe hepatitis B (CSHB), and 10 healthy controls (HCs) were determined by flow cytometry. The levels of related cytokines and the mRNA expression levels of transcription factors were measured using Enzyme-linked immunosorbent assay (ELISA) and real-time quantitative PCR (RT-PCR), respectively. RESULTS The Th17 cell frequency and the mRNA expression levels of RORc were increased in the CSHB group. The Treg cell frequency was increased and Th1 cell frequency and the mRNA expression levels of T-bet were decreased in chronic HBV infection. The levels of IL-21 were increased in the CSHB group and were positively correlated with AST, TB and DB in patients with chronic HBV infection. The Th17/Treg ratio was increased in the CSHB group and was positively correlated with liver injury in chronic HBV infection. CONCLUSIONS Th17/Treg imbalance and increased IL-21 are associated with liver injury in patients with chronic HBV infection. Restoring the Th17/Treg balance may be a novel immunotherapy for patients with CSHB.

Abstract
To investigate the effect of morphine on T helper lymphocyte differentiation and PI3K/AKT pathway mechanism, CD4+ lymphocytes were treated by phorbol-myristate-acetate (25 ng/ml) (PMA) plus ionomycin (1 μg/ml) in the presence of various concentrations of morphine (25, 50, 100, 200 ng/ml) for 4 h. Th1 and Th2 subsets, supernatant cytokines, and PI3K, AKT, and protein kinase C-theta (PKC-θ) levels were detected. The Th1 cell percentage, Th1-derived cytokines, and ratio of Th1/Th2 decreased in the presence of morphine in a concentration-dependent manner. However, Th2 cell percentage kept stable after morphine treatment. The phosphorylation of PI3K and AKT decreased, but the phosphorylation of PKC-θ did not change in the presence of morphine. The decreased percentage of Th1 cells and ratio of Th1/Th2 was recovered by naloxone concentration-dependently. Morphine can inhibit the differentiation of Th1 lymphocytes and decrease the ratio of Th1/Th2 via the pathway of PI3K/AKT. The effect can be inhibited by naloxone.

Abstract
The inducible T-cell co-stimulator (ICOS) belongs to the B7-CD28 immunoglobulin superfamily, which is currently the subject of intense study due to great successes gained in treatment of different malignancies by disrupting their family members. However, the role of ICOS played in colorectal cancer (CRC) remains poorly understood. A tissue microarray (n = 310) was stained with the ICOS specific antibody and ICOS expression is decreased in patients with either lymphatic or distant metastasis and inversely associated with CEA level and TNM stage of CRC patients. Importantly, high ICOS expression is significantly correlated with overall survival (OS) of CRC patients (n = 230, p < 0.001), and ICOS expression is also proved to be an independent prognostic factor by multivariate analysis. Surgical excised CRC specimens (n = 26) were enzymatically digested to get the tumor-infiltrating leukocytes and ICOS is mainly expressed on CD4(+) T cells and its ligand ICOSL is detected on macrophages and tumor cells. ICOS expression level is associated with increased cytotoxic T lymphocyte antigen (CTLA)-4 (p < 0.001) and programmed death (PD-1) (p = 0.005) expression on T cells and more infiltrated CD8(+) T cells (p < 0.001). Interestingly, ICOS(+)CD4(+) cells isolated from tumor tissues have high T-bet and interferon (IFN)γ expression, the characteristics of Th1 cells, compared to ICOS(-)CD4(+) cells. In addition, the correlation between the percentage of ICOS(+)CD4(+) T cells in tumor tissue and peripheral blood was detected. Conclusively, expression of ICOS is associated with improved survival in CRC and percentage of ICOS(+)CD4(+) cells acting as Th1 cells in either primary tumor tissue or peripheral blood may be a clinical biomarker for good prognosis of CRC patients.

Abstract
BACKGROUND Radix Saposhnikovia (RS), called "Fangfeng" in China, is commonly used in Chinese medicinal formulae to treat allergic and inflammatory diseases. However, the underlying mechanisms of RS in ameliorating allergy remain unknown. PURPOSE To study the effects of RS extract on allergic contact dermatitis (ACD) in a mouse model and to investigate the underlying mechanisms in vivo and ex vivo. METHODS ACD was induced by sensitizing the mice and treating an ear auricle with 1-chloro-2,4-dinitrobenzene (DNCB). RS extract was administered during the sensitization and/or elicitation phase. Ear swelling was noted and lymphocytic infiltration was investigated with hematoxylin and eosin staining. The cytokines in the sera and the supernatants of lymphocyte cultures were determined with enzyme-linked immunosorbent assays. Lymphocyte proliferation was assessed with a 3-(4,5)-dimethylthiazol-2-y1)-2,5-diphenyltetrazolium bromide (MTT) assay. The maturation of dendritic cells (DCs) and the differentiation of T cells were examined with flow cytometry. The mRNA expression of T-bet, GATA-3, and forkhead box p3 (Foxp3) was evaluated with real-time PCR. RESULTS RS extract (1.3 or 2.6 g/kg) markedly reduced the ear swelling and the intense cellular infiltration of inflammatory cells in the ear tissue. The ratio of interferon γ (IFN-γ)/interleukin 4 (IL-4) was reduced in the sera of the DNCB-sensitized mice and the lymphocyte culture supernatants after treatment with the extract. Further study of the initial stage of ACD revealed that RS extract prevented the differentiation of naïve T cells into Th1 cells, reduced the proportion of CD3(+)CD4(+) (Th) cells, and suppressed the secretion of IFN-γ and the expression of T-bet mRNA in lymphocytes. The RS extract also reduced the proportion of DCs in the sensitized mouse lymphocytes and the expression of CD40(+)CD86(+) cells in the DCs. CONCLUSION RS extract is effective in treating ACD because it regulates the development of DCs and DC-activated Th1 differentiation.

Abstract
BACKGROUND Psoriasis is a T-cell-mediated chronic inflammatory dermatosis. Th1, Th17 and Th22 cells are suggested to contribute to the pathogenesis of psoriasis. OBJECTIVE To determine whether treatment with the anti-tumor-necrosis-factor antagonist, adalimumab, induces significant modulation of the Th1, Th17 and Th22 pathways, and correlates cellular activity with clinical response. METHODS This study included 21 patients with moderate-to-severe psoriasis who were treated with adalimumab, and 10 healthy control subjects. Blood samples were collected at baseline and at week 12. Flow cytometry was used to analyze the frequency of circulating Th1, Th17 and Th22 cells. Real-time polymerase chain reaction was used to analyze the expression of T-bet (Th1-related), retinoid-acid receptor-related orphan receptor gamma t (RORγt, Th17-related) and aryl hydrocarbon receptor (AHR, Th22-related). An enzyme-linked immunosorbent assay was used to analyze the serum levels of IFN-γ, IL-17, IL-22, IL-6 and tumor necrosis factor-α (TNF-α). RESULTS At baseline, the frequencies of Th1, Th17 and Th22 cells were higher in psoriasis patients compared to the healthy controls. The expression of transcription factors T-bet, RORγt and AHR, and the serum levels of IFN-γ, IL-17, IL-22, IL-6 and TNF-α were higher in psoriasis patients compared to the healthy controls. After adalimumab therapy, there was a significant decline in the frequencies of Th1, Th17 and Th22 cells, and a concomitant decrease in the levels of their associated transcription factors and cytokines. CONCLUSION The results suggest that the anti-tumor-necrosis-factor antagonist, adalimumab, disrupts the Th1, Th17 and Th22 pathways, resulting in clinical improvement of psoriasis.

Abstract
Fingolimod is a new immunosuppressive agent approved by Food and Drug Administration (FDA) for treating multiple sclerosis (MS). It acts as a functional antagonist to downregulate the S1P1 receptor, which is known to signal through the Akt-mTOR pathway. We investigated the mechanism of fingolimod action in the classical animal model of MS: experimental autoimmune encephalomyelitis (EAE). Fingolimod treatment significantly reduced clinical scores and histopathology in this model, even when treatment was begun after the onset of pathology. The Akt-mTOR signaling pathway was shown to be activated in the EAE model, by measuring the abundance of downstream activation markers, pAkt and ps6k. And this pathway was inhibited when EAE mice were treated with fingolimod. Mice with EAE exhibited an increased frequency of Th1 cells in the spleen, with concomitant increases in the mRNA levels of Tbet and Ifng and increased IFN-γ production by activated splenocytes; the frequency of Treg cells, as well as mRNA levels of Foxp3 and Tgfb, was reduced, as was TGF-β production by activated splenocytes. After treatment with fingolimod, these parameters were reversed, suggesting that fingolimod treatment inhibits the Akt-mTOR axis in EAE, which affects the differentiation and function of Th1 and Treg cells. These results provide an insight into the mechanism of action of fingolimod treatment and may provide new ideas for treating EAE and MS.

Abstract
Infection with viral or bacterial pathogens has been linked with the development of multiple sclerosis (MS), while infection with helminth parasites has been associated protection against MS and other autoimmune diseases. Here we have used a murine model of MS, experimental autoimmune encephalomyelitis (EAE), to examine the effect of infection with the respiratory pathogen Bordetella pertussis infection on development of CNS inflammation. The data demonstrate that infection of mice with B. pertussis significantly attenuates the clinical course of EAE induced by active immunization or cell transfer. This was reflected in a significant reduction in VLA-4 and LFA-1 expression on T cells and infiltration of IL-17(+), IFN-γ(+) and IFN-γ(+)IL-17(+) CD4 T cells into the CNS. Infection with B. pertussis induced IL-10 production from dendritic cells in vitro and enhanced the frequency of IL-10-producing CD25(-)Foxp3(+/-) CD4(+) T cells in vivo. Furthermore, the suppressive effects of B. pertussis infection on EAE were lost in IL-10(-/-) mice. Our findings demonstrate that a bacterial infection of the respiratory tract can attenuate EAE by promoting production of the anti-inflammatory cytokine IL-10 that may suppress licensing of autoaggressive T cells in the lungs, thereby preventing their migration into the CNS.

Abstract
Signal transducer and activator of transcription (STAT) family molecules play essential roles during the differentiation of helper T cells from naïve precursors. Although the role of STAT3 in driving Th17 cell polarization has been well established, its role on Th2 responses to allergens remains incompletely understood. By employing T cell-specific STAT3 deficient mice, we demonstrate that STAT3 in T cells plays diverse role on Th2 cells depending on their locations in an animal model of allergic asthma. In the bronchial lymph nodes, STAT3-deficient T cells produced significantly reduced levels of Th2 cytokines. The frequencies of Th2 cells among CD4(+) T cells in the lung were comparable between STAT3-sufficient and STAT3-deficient T cells. By contrast, STAT3-deficient T cells in the airway exhibited significantly enhanced production of Th2 cell cytokines compared to STAT3-sufficient T cells. Interestingly, a major population of IL-4/5 producers among STAT3-deficient T cells in the airway co-produced IFNγ. The frequency of Th17 cells was significantly diminished whereas that of Th1 cells was increased in all the lung-associated tissues. Our results demonstrate the dynamic and opposing roles of STAT3 during the development of Th2 cells from bronchial lymph nodes to the airway and propose the need of careful consideration on STAT3-targeting approaches for the treatment of lung diseases.

Abstract
During infection, the release of damage-associated molecular patterns, so-called "alarmins," orchestrates the immune response. The alarmin IL-33 plays a role in a wide range of pathologies. Upon release, IL-33 signals through its receptor ST2, which reportedly is expressed only on CD4(+) T cells of the Th2 and regulatory subsets. Here we show that Th1 effector cells also express ST2 upon differentiation in vitro and in vivo during lymphocytic choriomeningitis virus (LCMV) infection. The expression of ST2 on Th1 cells was transient, in contrast to constitutive ST2 expression on Th2 cells, and marked highly activated effector cells. ST2 expression on virus-specific Th1 cells depended on the Th1-associated transcription factors T-bet and STAT4. ST2 deficiency resulted in a T-cell-intrinsic impairment of LCMV-specific Th1 effector responses in both mixed bone marrow-chimeric mice and adoptive cell transfer experiments. ST2-deficient virus-specific CD4(+) T cells showed impaired expansion, Th1 effector differentiation, and antiviral cytokine production. Consequently, these cells mediated little virus-induced immunopathology. Thus, IL-33 acts as a critical and direct cofactor to drive antiviral Th1 effector cell activation, with implications for vaccination strategies and immunotherapeutic approaches.

Abstract
T cell Ig and mucin domain-containing molecule-3 (Tim-3) is a negative regulator preferentially expressed on Th1 cells. Allergic asthma is a clinical syndrome well characterized by Th1/Th2 imbalance. To investigate the role of Tim-3 in the pathogenesis of asthma and its relationship with Th1/Th2 imbalance, a total of 40 patients with allergic asthma and 40 healthy controls were enrolled. Expression of Tim-3 and Th1/Th2 imbalance as well as the relationship between them was analyzed by flow cytometry and real-time PCR. Peripheral blood mononuclear cells (PBMCs) were cultured in vitro and anti-Tim-3 was used to block Tim-3 signaling; Th1/Th2 cytokines in the culture supernatant were detected by enzyme linked immunosorbent assay (ELISA). CD4(+) T cells and B cells were sorted and co-cultured in vitro, and anti-Tim-3 was used to block Tim-3 signaling; Total IgG/IgE in the culture supernatant was detected by ELISA. The mRNA level of T-bet and IFN-γ were significantly decreased in allergic asthma patients, while GATA-3 and IL-4 were significantly increased. Expression of Tim-3 on CD4(+) T cells was much higher in allergic asthma patients and it was negatively correlated with T-bet/GATA-3 ratio or IFN-γ/IL-4 ratio. Blocking of Tim-3 significantly increased Th1 cytokines (TNF-α and IFN-γ) and decreased Th2 cytokines (IL-4, IL-5, IL-13) in the culture supernatant of PBMCs. Blocking of Tim-3 dramatically reduced the production of IgG and IgE in the co-culture supernatant of CD4(+) T cells and B cells. In conclusion, Tim-3 was up-regulated in allergic asthma patients and related with the Th1/Th2 imbalance. Blocking of Tim-3 may be of therapeutic benefit by enhancing the Th1 cytokines response, down-regulating the Th2 cytokines response, and reducing IgG/IgE production.

Abstract
Zerumbone is a sesquiterpene compound isolated from the rhizome of wild ginger, Zingiber zerumbet Smith. The rhizomes of the plant are used as a spice and traditional medicine. Zerumbone was shown to possess anticarcinogenic, anti-inflammatory, and antioxidant properties. However, the antiallergic activity and the underlying mechanism of zerumbone have not been reported. Herein, we investigated the immunomodulatory effects of zerumbone on antigen-presenting dendritic cells (DCs) in vitro and its potential therapeutic effects against ovalbumin (OVA)-induced T helper 2 (Th2)-mediated asthma in mice. In the presence of zerumbone, lipopolysaccharide-activated bone marrow-derived DCs enhanced T cell proliferation and Th1 cell polarization in an allogeneic mixed lymphocyte reaction. In animal experiments, mice were sensitized and challenged with OVA, and were orally treated with different doses of zerumbone after sensitization. Circulating titers of OVA-specific antibodies, airway hyperresponsiveness to methacholine, histological changes in lung tissues, the cell composition and cytokine levels in bronchoalveolar lavage fluid, and cytokine profiles of spleen cells were assessed. Compared to OVA-induced hallmarks of asthma, oral administration of zerumbone induced lower OVA-specific immunoglobulin E (IgE) and higher IgG2a antibody production, attenuated airway hyperresponsiveness, prevented eosinophilic pulmonary infiltration, and ameliorated mucus hypersecretion. Zerumbone treatment also reduced the production of eotaxin, keratinocyte-derived chemokine (KC), interleukin (IL)-4, IL-5, IL-10, and IL-13, and promoted Th1 cytokine interferon (IFN)-γ production in asthmatic mice. Taken together, these results suggest that zerumbone exhibits an antiallergic effect via modulation of Th1/Th2 cytokines in an asthmatic mouse model.

Abstract
Immune regulation plays important but as-yet-unclear roles in the development of preeclampsia. This study explored potential contributions to immune regulation by dendritic cells (DCs) derived from peripheral blood of preeclampsia patients on the differentiation of Th1 and Th17 cells. Pregnant women with preeclampsia (n = 73) and healthy pregnant women (n = 80) were included in the study. Peripheral blood samples were collected from each participant, and DCs were derived from peripheral blood mononuclear cells in vitro. The phenotypes of DCs, identified by CD14, CD80, CD83, and CD86 expression, were detected by flow cytometry, and secretion of interleukin-23 (IL-23) into the culture medium by DCs was measured by ELISA. CD4 + T cells were separated by the magnetic beads and subjected to flow cytometry to determine their ability to differentiate to Th1 or Th17 cells. Compared with DCs derived from healthy pregnant women, DCs derived from preeclampsia patients expressed higher levels of CD83, CD80, and CD86 (P < 0.05). Additionally, secretion of IL-23 was higher in DCs derived from the preeclampsia group than from the control group (P < 0.001). DCs derived from preeclampsia patients also had a stronger ability to promote the differentiation of CD4 + T cells into Th1/Th17 cells when cultured with different cytokines (P < 0.01). Thus, altered phenotypes and functions of DCs may promote the abnormal balance of Th1 and Th17 in the development of preeclampsia.

Abstract
Salmonella has been a model pathogen for examining CD4 T cell activation and effector functions for many years due to the strength of the Th1 cell response observed during Salmonella infections, the relative ease of use of Salmonella, the availability of Salmonella-specific T cell reagents, and the well-characterized nature of the model system, the pathogen, and the immune response elicited. Herein, we discuss the use of Salmonella as a model pathogen to explore the complex interaction of T cells with their inflammatory environment. In particular, we address the issue of bystander activation of naïve T cells and non-cognate stimulation of activated and memory T cells. Further, we compare and contrast our current knowledge of these non-cognate responses in CD8 versus CD4 T cells. Finally, we make a case for Salmonella as a particularly appropriate model pathogen in the study of non-cognate CD4 T cell responses based on the strength of the Th1 response during infection, the requirement for CD4 T cells in bacterial clearance, and the well-characterized inflammatory response to conserved molecular patterns induced by Salmonella infection.

Abstract
Bordetella pertussis is a Gram-negative bacterium that causes the severe and sometimes lethal respiratory disease whooping cough in infants and children. There has been a recent resurgence in the number of cases of pertussis in several countries with high vaccine coverage. This has been linked with waning or ineffective immunity induced by current acellular pertussis vaccines. These acellular pertussis vaccines are formulated with alum as the adjuvant, which promotes strong antibody responses but is less effective at inducing Th1-type responses crucial for effective bacterial clearance. Studies in animal models have demonstrated that replacing alum with alternative adjuvants, such as toll-like receptor agonists, can promote more robust cell-mediated immunity and confer a high level of protection against infection following respiratory challenge.

Abstract
Protein fermentation by intestinal bacteria generates various compounds that are not synthesized by their hosts. An example is p-cresol, which is produced from tyrosine. Patients with chronic kidney disease (CKD) accumulate high concentrations of intestinal bacteria-derived p-cresyl sulfate (pCS), which is the major metabolite of p-cresol, in their blood, and this accumulation contributes to certain CKD-associated disorders. Immune dysfunction is a CKD-associated disorder that frequently contributes to infectious diseases among CKD patients. Although some studies imply pCS as an etiological factor, the relation between pCS and immune systems is poorly understood. In the present study, we investigated the immunological effects of pCS derived from intestinal bacteria in mice. For this purpose, we fed mice a tyrosine-rich diet that causes the accumulation of pCS in their blood. The mice were shown to exhibit decreased Th1-driven 2, 4-dinitrofluorobenzene-induced contact hypersensitivity response. The concentration of pCS in blood was negatively correlated with the degree of the contact hypersensitivity response. In contrast, the T cell-dependent antibody response was not influenced by the accumulated pCS. We also examined the in vitro cytokine responses by T cells in the presence of pCS. The production of IFN-γ was suppressed by pCS. Further, pCS decreased the percentage of IFN-γ-producing Th1 cells. Our results suggest that intestinal bacteria-derived pCS suppressesTh1-type cellular immune responses.

Abstract
PURPOSE Autoimmune inflammation of the retina causes vision loss in the majority of affected individuals. Th1 or Th17 cells initiate the disease on trafficking from the circulation into the eye across the retinal vascular endothelium. We investigated the ability of human Th1- and Th17-polarized cells to cross a simulated human retinal endothelium, and examined the role of IgG superfamily members in this process. METHODS Th1- and Th17-polarized cell populations were generated from human peripheral blood CD4(+) T cells, using two Th1- and Th17-polarizing protocols. Transendothelial migration assays were performed over 18 hours in Boyden chambers, after seeding the transwell membrane with human retinal endothelial cells. In some assays intercellular adhesion molecule 1 (ICAM-1), vascular cell adhesion molecule 1 (VCAM-1), or activated leukocyte cell adhesion molecule (ALCAM) blocking antibody, or isotype- and concentration-matched control antibody, was added to the upper chambers. RESULTS Th1- and Th17-polarized cells migrated equally efficiently across the human retinal endothelial monolayer. The percentage of IL-17(+) IFN-γ(-) Th17-polarized cells was reduced following migration. Blocking ICAM-1, but not VCAM-1 or ALCAM, significantly reduced migration of Th1- and Th17-polarized cells for a majority of human donors. CONCLUSIONS Taken in the context of other literature on transendothelial migration, our results illustrate the importance of investigating the specific tissue and vascular endothelium when considering helper T cell migration in autoimmune inflammation. Our findings further indicate that while generalizations about involvement of specific adhesion molecules in uveitis and other autoimmune disease may be possible, these may not apply to individual patients universally. The observations are relevant to the use of adhesion blockade for therapeutic purposes.

Abstract
Any therapeutic vaccination approach against HIV-1 must induce CTL and Th1 cells. But, therapeutic vaccination is more than that. For extensive application of a therapeutic vaccine several questions need to be solved in advance to achieve a global impact. In this commentary some of them are addressed. We analyze the epidemiology, sociology, economy and immunopathology related to the HIV/AIDS disease. Also, important technical issues and real possibilities to overcome at least some of the major limitation of the antiretroviral treatments in the pursuit of an effective vaccine are considered. From the integration of previous analyses some conclusions are drawn. Because it is just a commentary some arguments are not unveiled into their full extension. At the end, we discuss some issues in relation to the development of the vaccine candidate TERAVAC-HIV-1 as a case study.
