Chronic cerebral ischemia (CCI), a condition that can result in headaches, dizziness, cognitive decline, and stroke, is caused by a sustained decrease in cerebral blood flow. Statistics show that 70% of patients with CCI are aged > 80 years and approximately 30% are 45-50 years. The incidence of CCI tends to be lower, and treatment for CCI is urgent. Studies have confirmed that CCI can activate the corresponding mechanisms that lead to mitochondrial dysfunction, which, in turn, can induce mitophagy to maintain mitochondrial homeostasis. Simultaneously, mitochondrial dysfunction can aggravate the insufficient energy supply to cells and various diseases caused by CCI. Regulation of mitophagy has become a promising therapeutic target for the treatment of CCI. This article reviews the latest progress in the important role of mitophagy in CCI and discusses the induction pathways of mitophagy in CCI, including ATP synthesis disorder, oxidative stress injury, induction of reactive oxygen species, and Ca homeostasis disorder, as well as the role of drugs in CCI by regulating mitophagy.
慢性脑缺血(CCI)是一种可导致头痛、头晕、认知功能下降和中风的病症,由脑血流量持续减少引起。统计数据显示,70%的CCI患者年龄大于80岁,约30%为45 - 50岁。CCI的发病率往往较低,但其治疗迫在眉睫。研究证实,CCI可激活导致线粒体功能障碍的相应机制,进而诱导线粒体自噬以维持线粒体稳态。同时,线粒体功能障碍会加剧细胞能量供应不足以及由CCI引发的各种疾病。线粒体自噬的调节已成为治疗CCI的一个有前景的治疗靶点。本文综述了线粒体自噬在CCI中的重要作用的最新进展,并探讨了CCI中线粒体自噬的诱导途径,包括ATP合成障碍、氧化应激损伤、活性氧的诱导以及钙稳态紊乱,以及药物通过调节线粒体自噬在CCI中的作用。
