先天性淋巴样细胞(inate lymphoid cells,ILC)是一类异质性的免疫细胞家族,在机体抗感染、伤口愈合和组织修复等免疫过程中发挥重要作用。这些细胞是否参与脂质依赖性免疫仍然未被探索。在这里,我们发现来自各种组织的小鼠ILC表达脂质呈递分子CD 1d,其中第3组ILC(ILC 3)显示出最高的表达水平。在ILC 3家族中,天然细胞毒性触发受体(NCR)− CCR 6+细胞显示出最高水平的CD 1d。ILC上CD 1d的表达在功能上是相关的,因为ILC 3可以在体外和体内获得脂质,并将脂质加载到CD 1d上,以介导对恒定自然杀伤T(iNKT)细胞的T细胞受体的呈递。相反,体外CD 1d的参与和体内脂质抗原的施用诱导ILC 3活化和IL-22的产生。综上所述,我们的数据揭示了ILC在CD 1d介导的免疫中以前未被认识到的作用,它可以调节组织稳态和炎症反应。
Innate lymphoid cells (ILCs) are a heterogeneous family of immune cells that play a critical role in a variety of immune processes including host defence against infection, wound healing and tissue repair. Whether these cells are involved in lipid‐dependent immunity remains unexplored. Here we show that murine ILCs from a variety of tissues express the lipid‐presenting molecule CD1d, with group 3 ILCs (ILC3s) showing the highest level of expression. Within the ILC3 family, natural cytotoxicity triggering receptor (NCR)− CCR6+ cells displayed the highest levels of CD1d. Expression of CD1d on ILCs is functionally relevant as ILC3s can acquire lipids in vitro and in vivo and load lipids on CD1d to mediate presentation to the T‐cell receptor of invariant natural killer T (iNKT) cells. Conversely, engagement of CD1d in vitro and administration of lipid antigen in vivo induce ILC3 activation and production of IL‐22. Taken together, our data expose a previously unappreciated role for ILCs in CD1d‐mediated immunity, which can modulate tissue homeostasis and inflammatory responses.
