高迁移率族蛋白B1与肝缺血再灌注损伤的关系

Association between high-mobility group box B1 and hepatic ischemia-reperfusion injury

高迁移率族蛋白B1(HMGB1)是一种广泛分布于真核细胞中的DNA结合蛋白。当组织损伤时,HMGB1作为内源性危险信号激活机体免疫系统,介导无菌炎症反应。目前已发现其在肝脏缺血再灌注损伤中发挥关键作用。归纳了近年HMGB1在肝缺血再灌注中如何发挥促炎作用以及以HMGB1为靶点治疗肝缺血再灌注损伤的研究进展。

High-mobility group box B1 (HMGB1) is a DNA-binding protein widely distributed in eukaryotic cells. When tissue damage occurs, HMGB1 acts as an endogenous risk signal to activate the body’s immune system and mediate aseptic inflammatory response. Current research findings have shown that HMGB1 plays a key role in hepatic ischemia-reperfusion injury. This article summarizes the recent research advances in the proinflammatory role of HMGB1 in hepatic ischemia-reperfusion and HMGB1 as a target for the treatment of hepatic ischemia-reperfusion injury.
