虽然控制调节性T细胞(表达Foxp 3的调节性T细胞,分泌IL-10的Tr 1细胞)和Th 17细胞在啮齿类动物的生理途径已经确定,控制这些分化途径在人类的因素还没有很好地理解。在这项研究中,我们表明,IL-27促进IL-10分泌Tr 1细胞的分化,同时抑制Th 17的产生和与Th 17功能相关的分子。此外,IL-27抑制树突状细胞上的IL-17极化细胞因子,这反过来减少T细胞的IL-17分泌。我们的研究结果表明,IL-27通过促进IL-10分泌Tr 1细胞和抑制Th 17细胞在人T细胞中起着关键作用,从而提供了一种双重调节机制来控制自身免疫和组织炎症。
Although the physiologic pathways that control regulatory T cells (Foxp3-expressing regulatory T cells, IL-10-secreting Tr1 cells) and Th17 cells in rodents have been defined, the factors that control these differentiation pathways in humans are not well understood. In this study, we show that IL-27 promotes the differentiation of IL-10-secreting Tr1 cells while inhibiting Th17 generation and molecules associated with Th17 function. Furthermore, IL-27 inhibits IL-17-polarizing cytokines on dendritic cells, which in turn decrease IL-17 secretion from T cells. Our results demonstrate that IL-27 plays a key role in human T cells by promoting IL-10-secreting Tr1 cells and inhibiting Th17 cells and thus provides a dual regulatory mechanism to control autoimmunity and tissue inflammation.
