摘要:

【摘要】 脓毒症早期,中性粒细胞过度迁移、自噬活性增强引发全身炎症反应;而在晚期,中性粒细胞迁移能力下降、自噬活性减退,导致机体免疫抑制。对于脓毒症而言任何一个免疫机制环节都是不可或缺的,目前临床通过针对一个或数个免疫靶点干预脓毒症免疫抑制剂状态。文章综述了脓毒症发生时,中性粒细胞发生凋亡延迟、迁移趋化失调、释放胞外诱捕网等特有生物学行为使机体从全身炎症反应状态转变为免疫抑制状态的免疫机制。文章拟讨论近年对中性粒细胞在脓毒症发病机制中相关研究进展,对改善脓毒症后期强烈免疫抑制和免疫增强治疗提供参考。

Abstract:

【Abstract】 In the early stage of sepsis, excessive migration of neutrophils and enhanced autophagy activity lead to systemic inflammation. In the later stage, neutrophil migration and autophagy activity decrease, leading to immunosuppression. For sepsis, any immune mechanism link is indispensable. The clinical intervention of sepsis immunosuppressive state currently targets one or several immune targets. This article reviewed the immune mechanism of neutrophils' specific biological behaviors, such as delayed apoptosis, dysregulated migration and chemotaxis, and release of extracellular traps, to change the body from a systemic inflammatory response state to an immunosuppressive state during sepsis. This review intends to discuss the recent research advances on neutrophils in the pathogenesis of sepsis and provide reference for improving potent immunosuppression and immunoenhancing therapy in the late stage of sepsis.
