Abstract

In addition to thymus-derived or natural T regulatory (nT(reg)) cells, a second subset of induced T regulatory (iT(reg)) cells arises de novo from conventional CD4(+) T cells in the periphery. The function of iT(reg) cells in tolerance was examined in a CD45RB(high)CD4(+) T cell transfer model of colitis. In situ-generated iT(reg) cells were similar to nT(reg) cells in their capacity to suppress T cell proliferation in vitro and their absence in vivo accelerated bowel disease. Treatment with nT(reg) cells resolved the colitis, but only when iT(reg) cells were also present. Although iT(reg) cells required Foxp3 for suppressive activity and phenotypic stability, their gene expression profile was distinct from the established nT(reg) "genetic signature," indicative of developmental and possibly mechanistic differences. These results identified a functional role for iT(reg) cells in vivo and demonstrated that both iT(reg) and nT(reg) cells can act in concert to maintain tolerance.

摘要

除了胸腺来源的或天然的调节性T细胞(nT(reg)细胞)外,诱导性调节性T细胞(iT(reg)细胞)的第二个亚群在外周由传统的CD4(+) T细胞重新产生。在结肠炎的CD45RB(high)CD4(+) T细胞转移模型中检测了iT(reg)细胞在耐受性方面的功能。原位产生的iT(reg)细胞在体外抑制T细胞增殖的能力方面与nT(reg)细胞相似,并且它们在体内的缺失会加速肠道疾病。用nT(reg)细胞治疗可缓解结肠炎,但只有当iT(reg)细胞也存在时才行。虽然iT(reg)细胞的抑制活性和表型稳定性需要Foxp3,但它们的基因表达谱与已确定的nT(reg)“基因特征”不同,这表明存在发育差异以及可能的机制差异。这些结果确定了iT(reg)细胞在体内的功能作用,并证明iT(reg)细胞和nT(reg)细胞都可以协同作用以维持耐受性。
