T helper cell 17 (Th17) is a distinct subset of T lymphocytes characterized by the predominant secretion of interleukin-17 (IL-17). The differentiation process of Th17 cells is orchestrated by a combination of transforming growth factor-β (TGFβ), interleukin-1 (IL-1), and interleukin-6 (IL-6). Which cytokines are potential inhibitors of Th17 cell development?
