Summary: Methotrexate (MTX) is a common treatment for rheumatoid arthritis (RA) but its precise mechanisms of action remain unclear. In this study, DNA microarray analyses of CD4+ T cells in RA patients revealed that TP63, specifically its isoform TAp63, was downregulated after MTX treatment. TAp63 was highly expressed in Th17 cells and suppressed by MTX in vitro. Knockdown of TAp63 in mouse Th17 cells improved arthritis symptoms. Furthermore, TAp63 knockdown in CD4+ T cells promoted Foxp3 expression and enhanced the suppressive function of induced Treg cells. In summary, TAp63 suppresses Foxp3 expression and worsens autoimmune arthritis.

Summary: The study identified a novel regulatory T-cell population expressing CD103, which is programmed to prevent excessive type 2 inflammation and maintain homeostasis in the respiratory tract. This has important therapeutic implications for allergic and autoimmune disorders.

Summary: The transcription factor FOXP3 is crucial for the development and function of CD4(+)FOXP3(+) regulatory T (Treg) cells. Alterations in the expression of FOXP3 isoforms are associated with inflammatory disease progression. This study investigates the effects of a specific FOXP3 mutation on Treg cell subsets. The findings suggest that the full-length FOXP3 isoform is important for maintaining Treg cell lineage stability but not essential for Treg cell activation.

Summary: This study investigated the role of CD39 expression in Treg cell subsets in COVID-19 immunopathogenesis and found that CD39(+) Tregs increased with disease severity in adult patients, while they decreased in an age-dependent manner in juvenile patients.

Summary: Co-culturing human iTregs with MSCs enhances the stability of FOXP3 expression and suppressive function, with a key mechanism being MSC mt transfer via tunneling nanotubules. Mitochondrial metabolic function drives MSC mt transfer to proliferating iTregs, stabilizing FOXP3 expression and promoting suppressive function in inflammatory conditions.

Summary: Regulatory T (T reg) cells are vital in maintaining tolerance and preventing fatal autoimmunity. This study reveals the importance of Tet enzymes and DNA demethylation in promoting Treg cell differentiation in the thymus. Tet3 is specifically involved in the development of CD4 single-positive thymocytes and plays a critical role in TCR-dependent IL-2 production, which is essential for chromatin remodeling and the upregulation of FoxP3.

Summary: This study found that acute and chronic HIV infection are associated with an increase in total, effector memory, and terminally differentiated FoxP3(+) CD8 T-cells. Early antiretroviral therapy (ART) only normalized the frequencies of total FoxP3(+) CD8 T-cells. The study also observed increased immune activation, senescence, and PD-1 expression in FoxP3(+) CD8 T-cells during acute and chronic infection, which were not normalized by early ART.

Summary: The study suggests that T cell anergy induction plays a crucial role in maintaining the balance of self-immunity. Disruption in peripherally-induced Tregs formation or exposure to selective self-peptides can result in an accumulation of anergic cells. Additionally, microbial antigens can induce anergy and promote the conversion of naive T cells to regulatory T cells.

Summary: Regulatory T cells (Tregs) orchestrate antitumor immune responses, with TGF-beta promoting Treg generation through NF-kappa B/p300 and SMAD signaling pathways. GO-Y030 inhibits Treg generation and stability by blocking these pathways, resulting in potent anticancer effects in vivo tumor models.
