氧化应激-线粒体功能异常与视网膜神经节细胞凋亡的关系

Oxidative stress-mitochondrial dysfunction and the relationship with retinal ganglion cell apoptosis

线粒体既是细胞内能量转换器,又是决定细胞存活及凋亡的重要因素。线粒体损伤、功能失调与多种神经元退行性变疾病发生发展均密切相关。青光眼为视神经病变的一种,近年来研究发现,线粒体的氧化应激在青光眼的发病及视网膜神经节细胞损害过程中尤其重要。本文对氧化应激-线粒体功能异常与视网膜神经节细胞凋亡关系的最新研究进展作以综述。

Mitochondria play an important role in energy （ ATP ） production through oxidative phosphorylation pathway and the regulation of cell death by apoptosis. Mitochondrial dysfunction has been implicated in the pathophysiology of a number of neurodegenerative diseases. Glaucoma as a neurodegenerative disorder, mitochondrial oxidative stress in the pathogenesis of glaucoma and the damage of RGCs has received close attention in recent years. ln this article, we reviewed the current evidences and recent advances in the relationship between mitochondrial oxidative stress and the RGCs apoptosis.
