摘要:

cGAS-STING在心脏、肝脏、脑、肾脏等器官的缺血再灌注损伤中发挥着重要的作用,但其在脑缺血再灌注损伤中的作用及机制尚缺乏系统的综述。此次综述首先概述了cGAS-STING通路的组成,然后分析其在脑缺血再灌注损伤中自噬、铁死亡、细胞焦亡、钙稳态失调、炎症反应、破坏血脑屏障、小胶质细胞转化以及补体系统方面的作用。进而分析了cGAS-STING通路抑制剂在脑缺血再灌注损伤治疗的价值。最终得出,cGAS-STING通路可通过多种机制调控脑缺血再灌注损伤,抑制cGAS-STING通路可能有助于脑缺血再灌注损伤的治疗。

Abstract: The cGAS–STING pathway plays an important role in ischemia-reperfusion injury in the heart, liver, brain, and kidney, but its role and mechanisms in cerebral ischemia-reperfusion injury have not been systematically reviewed. Here, we outline the components of the cGAS–STING pathway and then analyze its role in autophagy, ferroptosis, cellular pyroptosis, disequilibrium of calcium homeostasis, inflammatory responses, disruption of the blood–brain barrier, microglia transformation, and complement system activation following cerebral ischemia-reperfusion injury. We further analyze the value of cGAS– STING pathway inhibitors in the treatment of cerebral ischemia-reperfusion injury and conclude that the pathway can regulate cerebral ischemia-reperfusion injury through multiple mechanisms. Inhibition of the cGAS–STING pathway may be helpful in the treatment of cerebral ischemia-reperfusion injury.

Key words: calcium homeostasis, cellular autophagy, cerebral ischemia-reperfusion injury, cGAS–STING pathway, ferroptosis, gut–brain–microbiota axis, inflammatory, light chain 3, microglial cells, Syntaxin-17 protein
