FoxP 3+调节性T(Treg)细胞在实验性自身免疫性脑脊髓炎期间在中枢神经系统(CNS)中积累,并且已显示限制神经炎症的程度并促进临床恢复。最近的证据表明,Treg细胞失去FoxP 3的表达,并假设效应细胞的特性后,刺激与促炎细胞因子提出了问题,他们在发炎的中枢神经系统的稳定性。在本期欧洲免疫学杂志中,奥康纳等人[Eur. J. Immunol.2012. 42:1164-1173]显示CNS浸润性Treg细胞通过下调IL-6受体维持其抑制表型。这篇评论讨论了这一发现,特别是与多发性硬化症的治疗相关。
FoxP3+regulatory T (Treg) cells accumulate in the central nervous system (CNS) during experimental autoimmune encephalomyelitis and have been shown to limit the extent of neuroinflammation and to facilitate clinical recovery. The recent demonstration that Treg cells lose FoxP3 expression and assume effector cell characteristics upon stimulation with proinflammatory cytokines has raised questions about their stability in the inflamed CNS. In this issue of the European Journal of Immunology, O'Connor et al. [Eur. J. Immunol. 2012. 42: 1164–1173] show that CNS‐infiltrating Treg cells maintain their suppressor phenotype by downregulating the IL‐6 receptor. This commentary discusses the finding particularly with relevance to therapy of multiple sclerosis.
