凝血调节蛋白是一种内皮膜蛋白,可将凝血酶(T)从促凝蛋白酶转化为抗凝酶。我们发现TM的n端也可以结合和中和死亡介质HMGB1。T-TM络合物降解与TM结合的HMGB1,形成des-HMGB1。HMGB1在止血、先天免疫和损伤部位修复中起触发因子作用。然而,系统性HMGB1在DIC、休克和MOF中起中介作用。因此TM和HMGB1形成了一个自卫系统。
英文摘要
An endothelial membrane protein, Thrombomodulin(TM) converts thrombin(T) from a procoagulant protease to an anticoagulant. We found that N-terminus of TM also can bind and neutralize death mediator HMGB1. T-TM complex degrades the HMGB1 bound to TM forming des-HMGB1. HMGB1 acts as triggering factor for hemostasis, innate immune and repair at injury sites. However systemic HMGB1 acts as a mediator for DIC, shock and MOF. Thus TM and HMGB1 is form a self-defense system.
