脑缺血灌注损伤主要指缺血脑组织恢复血液灌注后,脑组织损伤加重的病理现象。涉及缺血再灌注损伤后的相关细胞分子通路十分广泛,如 NF-κB 通路、酸敏感离子通路、超极化激活环核苷酸门控阳离子通路、丝裂原激活蛋白激酶通路、基质金属蛋白酶通路和水通道蛋白通路等,其主要参与再灌注损伤机制包括基于炎症、凋亡相关通路调节机制;基于钙离子作用相关通路调节机制;基于细胞凋亡通路调节机制以及脑水肿变化的通路机制。本文拟总结主要参与脑缺血再灌注损伤后的细胞分子通路及其作用机制,为进一步了解再灌注损伤机制提供参考。
腦缺血灌註損傷主要指缺血腦組織恢複血液灌註後,腦組織損傷加重的病理現象。涉及缺血再灌註損傷後的相關細胞分子通路十分廣汎,如 NF-κB 通路、痠敏感離子通路、超極化激活環覈苷痠門控暘離子通路、絲裂原激活蛋白激酶通路、基質金屬蛋白酶通路和水通道蛋白通路等,其主要參與再灌註損傷機製包括基于炎癥、凋亡相關通路調節機製;基于鈣離子作用相關通路調節機製;基于細胞凋亡通路調節機製以及腦水腫變化的通路機製。本文擬總結主要參與腦缺血再灌註損傷後的細胞分子通路及其作用機製,為進一步瞭解再灌註損傷機製提供參攷。

Cerebral-ischemia reperfusion injury refers to cerebral tissue exacerbation injury after blood perfusion is restored in ischemic area. The related cellular pathways involved in ischemia reperfusion are varied, such as NF-κB signal pathway, acid sensing ion channels, hyperpolarization-activated cyclic-nucleotide-gated, MAPKs signal pathway, Matrix metalloproteinases and AQP4. The main mechanism that participates in reperfusion injury involves the cellular pathway based on inflammation reaction and apoptosis, pathway based on calcium interaction, pathway based on cell apoptosis and the one based on brain edema. This article is intended to summarize the changes of cellular signal pathways and their mechanisms in ischemia reperfusion injury, thus shedding light on the injury mechanism after cerebral ischemia reperfusion.
