Stat3 signaling is essential for the induction of RORγt and subsequent Th17 cell differentiation. However, downstream targets expression remain largely unknown. We show here that a novel isoform Sox5, named Sox5t, induced in cells Stat3-dependent manner. In vivo, T cell-specific Sox5-deficient mice exhibit impaired differentiation are resistant to experimental autoimmune encephalomyelitis delayed-type hypersensitivity. Retrovirus-mediated Sox5 together with c-Maf induces even Stat3-deficient...

Abstract The lungs serve as the primary organ for respiration, facilitating vital exchange of gases with bloodstream. Given their perpetual exposure to external particulates and pathogens, they possess intricate protective barriers. Cellular adhesion in is robustly maintained through tight junctions, adherens desmosomes. Furthermore, pulmonary system features a mucociliary clearance mechanism that synthesizes mucus transports it outside. This enriched chemical barriers like antimicrobial...

Abstract Objectives IgG4-related disease (IgG4-RD) is a systemic autoimmune with an unknown etiology, affecting single/multiple organ(s). Pathological findings include the infiltration of IgG4-producing plasma cells, obliterative phlebitis, and storiform fibrosis. Although immunological studies have shed light on dysregulation lymphocytes in IgG4-RD pathogenesis, role non-immune cells remains unclear. This study aimed to investigate demographics characteristics explore potential biomarkers...

Abstract Group 2 innate lymphoid cells (ILC2s) are a subset of lymphocytes that produce type cytokines, including IL-4, IL-5, and IL-13. GATA3 is critical transcription factor for ILC2 development at multiple stages. However, when how induced to the levels required remains unclear. Herein, we identify ILC2-specific GATA3-related tandem super-enhancers (G3SE) induce high in ILC2-committed precursors. G3SE-deficient mice exhibit deficiency bone marrow, lung, liver, small intestine with minimal...

Immune homeostasis in the intestine is tightly controlled by FOXP3+ regulatory T cells (Tregs), defects of which are linked to development chronic conditions, such as inflammatory bowel disease (IBD). As a mechanism immune evasion, several species intestinal parasites boost Treg activity.

Methotrexate (MTX) is a standard, first-line therapy for rheumatoid arthritis (RA); however, its precise mechanisms of action other than antifolate activity are largely unknown. We performed DNA microarray analyses CD4+ T cells in patients with RA before and after MTX treatment found that TP63 was the most significantly downregulated gene treatment. TAp63, an isoform TP63, highly expressed human IL-17–producing Th (Th17) suppressed by vitro. Murine TAp63 at high levels lower thymus-derived...

The transcriptional regulator Foxp3 is critical Treg development and function, controlling expression genes important Tregs through interactions with binding partners. We previously reported KAP1 as a partner FOXP3 human Tregs, but mechanisms by which affects function were unclear. In this study, we analyzed mice Treg-specific deletion found that they develop spontaneous autoimmune...
