Foxp3+T调节细胞(Treg)亚群在维持自身抗原免疫动态平衡中起着至关重要的作用。这些细胞的缺乏或功能障碍是许多自身免疫性疾病的发生和发展的原因。因此,操纵这些细胞可能为治疗自身免疫性疾病提供一种新的治疗方法。本文就Treg亚群的分类、发育和功能特征等方面的研究进展作一综述。将特别强调转化生长因子-β诱导的CD4+Foxp3+细胞(ITregs)在已建立的自身免疫性疾病中的治疗作用。此外,iTregs和自然产生的胸腺来源的CD4+CD25+Foxp3+调节性T细胞(NTregs)的相似性和差异性也被讨论过。促炎细胞因子IL-6可以将nTregs转化为产生IL-17的细胞,而由转化生长因子-β诱导的iTregs对这种细胞因子的作用具有抵抗力。了解这种差异可能在确定Treg如何用于已建立的自身免疫性疾病的治疗中发挥关键作用。
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.
