摘　要：

脑缺血再灌注损伤的发生机制十分复杂，伴随着钙超载以及ROS 生成爆发导致线粒体形态和功能异常。线粒体动力学( 融合、分裂) 是维持线粒体正常形态和功能的关键，该过程主要由线粒体融合蛋白和分裂蛋白调控。线粒体融合/ 分裂失衡与脑缺血再灌注损伤的发生发展密切相关，研究表明Ca2+ 超载和ROS 通过影响线粒体动力学蛋白而调控线粒体融合和分裂，决定神经元的存亡。该文就脑缺血再灌损伤中涉及的线粒体动力学相关分子及相关机制的研究作一综述，为临床上减轻脑损伤疾病提供新的思路。

Abstract:

Cerebral ischemia/reperfusion injury occurs by complex mechanisms, with calcium overload and bursts of ROS production leading to abnormal mitochondrial morphology and function. Mitochondrial dynamics (fusion, fission) are critical for maintaining normal mitochondrial morphology and function, and the process is mainly regulated by mitochondrial fusion and fission proteins. Mitochondrial fusion/fission imbalance is closely related to the development of cerebral ischemia/reperfusion injury, and studies have shown that Ca2+ overload and ROS regulate mitochondrial fusion and fission by affecting mitochondrial kinetic proteins, which determine neuronal survival. This paper presents a review of studies involving molecules related to mitochondrial dynamics and related mechanisms in cerebral ischemia/reperfusion injury to provide new ideas for clinical mitigation of brain injury diseases.
