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. In this review, we provide current opinions concerning the classification, developmental and functional characterizations of Treg subsets. A particular emphasis will be focused on the therapeutic role of TGF-β-induced CD4+Foxp3+ cells (iTregs) in established autoimmune disease. Moreover, the similarity and disparity of iTregs and naturally occurring, thymus-derived CD4+CD25+Foxp3+ regulatory T cells (nTregs) have also be discussed. While the proinflammatory cytokine IL-6 can convert nTregs to IL-17-producing cells, iTregs induced by TGF-β are resistant to the effects of this cytokine. Understanding this difference may play a key role in determining how Tregs can be used in the treatment of established autoimmune diseases.
