摘　　要：肝衰竭是常见的严重肝病综合征,病死率高。肠道屏障作为一个整体,其功能和结构的完整性与肝衰竭发生发展密切相关。环鸟苷酸-腺苷酸合酶(cGAS)-干扰素基因刺激因子(STING)信号通路通过识别病原体入侵及宿主自身细胞损伤产生的DNA,诱导Ⅰ型干扰素的产生,参与先天免疫反应。大量研究表明,cGAS-STING通路的激活对肠道屏障的细胞结构、黏膜成分及共生菌群均能产生影响。本文概述了cGAS-STING信号通路与肝衰竭肠道屏障损伤之间的关系,希望为临床肝衰竭的治疗提供新思路。Liver failure is a common severe syndrome of liver diseases with high mortality.The function and structural integrity of the intestinal barrier as an entity are closely associated with the development and progression of liver failure.The cGAS-STING signaling pathway can participate in innate immune response by recognizing DNA produced by pathogen invasion and host cell damage and inducing the production of type I interferon.Numerous studies have shown that activation of the cGAS-STING pathway can significantly impact the cellular structure,mucosal components,and commensal bacteria of the intestinal barrier.This article reviews the interplay between the cGAS-STING signaling pathway and intestinal barrier disruption in liver failure,in order to provide novel insights for the clinical management of liver failure.
