Transforming growth factor-β1 in regulatory T cell biology.

ABSTRACT: Transforming growth factor-β1 (TGF-β1) is inextricably linked to regulatory T cell (T_reg) biology. However, precisely untangling the role for TGF-β1 in T_reg differentiation and function is complicated by the pleiotropic and context-dependent activity of this cytokine and the multifaceted biology of T_regs. Among CD4⁺ T cells, T_regs are the major producers of latent TGF-β1 and are uniquely able to activate this cytokine via expression of cell surface docking receptor glycoprotein A repetitions predominant (GARP) and αv integrins. Although a preponderance of evidence indicates no essential roles for T_reg-derived TGF-β1 in T_reg immunosuppression, TGF-β1 signaling is crucial for T_reg development in the thymu
