白细胞介素-15 (Interleukin-15, IL-15)是一种重要的IL-2相关细胞因子,其在Th17细胞生物学中的作用尚未完全阐明。在这里,我们发现外源性IL-15减少了Th17培养中IL-17A的产生。使用抗体中和IL-15导致Th17培养中IL-17A的产生增加。与体外培养的WT细胞相比,Il15 - / -和Il15r - / - T细胞培养的上清液中IL-17A产生的频率更高,IL-17A的含量也更高。IL-15下调IL-17A的产生,独立于ROR-γt、Foxp3和IFN-γ的表达。Th17和APC细胞均产生IL-15,诱导CD4 T细胞中il - 17位点的抑制因子STAT5结合。此外,在髓鞘少突胶质细胞糖蛋白(MOG)诱导的EAE模型中,与WT对照组相比,Il15−/−小鼠表现出加重的炎症,与CD4+ T细胞产生的IL-17A增加相关。外源性IL-15给药和IL-17A中和降低了IL-15−/−小鼠EAE的严重程度。综上所述,这些数据表明IL-15在微调IL-17A的产生和Th17介导的炎症中具有负调控作用。
Interleukin-15 (IL-15) is an important IL-2 related cytokine, whose role in Th17 cell biology has not been fully elucidated. Here we show that exogenous IL-15 decreased IL-17A production in Th17 cultures. Neutralizing IL-15 using an antibody led to increases in IL-17A production in Th17 cultures. Both Il15−/− and Il15r−/− T cell cultures displayed higher frequency of IL-17A producers and higher amounts of IL-17A in the supernatants, compared to WT cells in vitro. IL-15 downmodulated IL-17A production, independently of ROR-γt, Foxp3 and IFN-γ expression. Both Th17 and APC cells produced IL-15, which induced binding of STAT5, an apparent repressor to the Il17 locus in CD4 T cells. Also, in a model of myelin oligodendrocyte glycoprotein (MOG) induced EAE, Il15−/− mice displayed exacerbated inflammation, correlating with increased IL-17A production by their CD4+ T cells, compared to WT controls. Exogenous IL-15 administration and IL-17A neutralization reduced the severity of EAE in Il15−/− mice. Taken together, these data indicate that IL-15 has a negative regulatory role in fine-tuning IL-17A production and Th17 mediated inflammation.
