急性病毒性脑炎需要迅速消除病原体,而不会对旁观者组织造成重大损害。在这里,我们证明了IL-10,一种强大的抗炎细胞因子,是在冠状病毒感染小鼠大脑中CD8 T细胞感染的高峰期瞬间产生的。IL-10+CD8和IL-10−CD8T细胞在急性疾病期间相互转换,可能与最近的抗原暴露有关。值得注意的是,IL-10+CD8T细胞比IL-10-−CD8T细胞具有更高的活性和杀伤活性,表达更高水平的促炎细胞因子和趋化因子以及细胞毒蛋白。尽管这些细胞是高度促炎的,但这些细胞表达的IL-10是有功能的。此外,CD8T细胞产生的IL-10降低了冠状病毒诱导的急性脑炎小鼠的疾病严重程度,表明了一种将免疫病理变化降至最低的自我调节机制。
Acute viral encephalitis requires rapid pathogen elimination without significant bystander tissue damage. Here, we show that IL-10, a potent anti-inflammatory cytokine, is produced transiently at the peak of infection by CD8 T cells in the brains of coronavirus-infected mice. IL-10+CD8 and IL-10−CD8 T cells interconvert during acute disease, possibly based on recent antigen exposure. Strikingly, IL-10+CD8 T cells were more highly activated and cytolytic than IL-10−CD8 T cells, expressing higher levels of proinflammatory cytokines and chemokines, as well as cytotoxic proteins. Even though these cells are highly proinflammatory, IL-10 expressed by these cells was functional. Further, IL-10 produced by CD8 T cells diminished disease severity in mice with coronavirus-induced acute encephalitis, suggesting a self-regulatory mechanism that minimizes immunopathological changes.
