Foxp3+T regulatory cell (Treg) subsets play a crucial role in the maintenance of immune homeostasis against self-antigen. The lack or dysfunction of these cells is responsible for the pathogenesis and development of many autoimmune diseases. Therefore, manipulation of these cells may provide a novel therapeutic approach to treat autoimmune diseases and prevent allograft rejection during organ transplantation. In the article, we will provide current opinions concerning the classification, developmental and functional characterizations of Treg subsets. A particular emphasis will be focused on transforming cell growth factor beta (TGF-beta) and its role in the differentiation and development of induced regulatory T cells (iTregs) in the periphery. Moreover, the similarity and disparity of iTregs and naturally occurring, thymus-derived CD4+CD25+Foxp3+ regulatory T cells (nTregs) will also be discussed. While proinflammatory cytokine IL-6 can convert nTregs to IL-17-producing cells, peripheral Tregs induced by TGF-beta are resistant to this cytokine. This difference may affect the role of each in the adaptive immune response.
