摘要:

线粒体的功能异常在脑出血患者的继发性脑损伤中扮演着十分重要的作用,在受损的线粒体中,细胞内Ca2+超载、ATP减少和活性氧积累是加剧脑出血继发脑损伤的主要因素,而线粒体自噬是清除受损线粒体,调控线粒体功能异常的重要途经。脑出血后,细胞或组织中的活性氧会通过PINK1/Parkin、FUNDC1、OPTN/核因子E2相关因子2(Nrf2)等途径启动线粒体自噬,防止进一步的脑部氧化损伤。因此,以线粒体自噬为靶点,研究其功能以及去除炎症反应的机制,对脑出血后的继发性脑损伤治疗有着重要意义。文章总结了脑出血、线粒体功能异常、线粒体自噬以及三者之间的关系。介绍了脑出血的损伤形成机制;脑出血后线粒体功能异常,活性氧的堆积和炎症反应,相关通道的开放和自噬的产生以及线粒体动力学;随后介绍了在脑出血后线粒体自噬调控减少线粒体损伤和功能异常的机制。最后总结了在脑出血中可以调控促进线粒体自噬的药物。虽然目前只发现了少量调节脑出血中线粒体自噬的药物,其中大部分处于临床前阶段,需要进一步研究,但从长远来看,线粒体自噬仍是脑出血非常有效和有前景的治疗标靶。

Abstract: Intracerebral hemorrhage is a life-threatening condition with a high fatality rate and severe sequelae. However, there is currently no treatment available for intracerebral hemorrhage, unlike for other stroke subtypes. Recent studies have indicated that mitochondrial dysfunction and mitophagy likely relate to the pathophysiology of intracerebral hemorrhage. Mitophagy, or selective autophagy of mitochondria, is an essential pathway to preserve mitochondrial homeostasis by clearing up damaged mitochondria. Mitophagy markedly contributes to the reduction of secondary brain injury caused by mitochondrial dysfunction after intracerebral hemorrhage. This review provides an overview of the mitochondrial dysfunction that occurs after intracerebral hemorrhage and the underlying mechanisms regarding how mitophagy regulates it, and discusses the new direction of therapeutic strategies targeting mitophagy for intracerebral hemorrhage, aiming to determine the close connection between mitophagy and intracerebral hemorrhage and identify new therapies to modulate mitophagy after intracerebral hemorrhage. In conclusion, although only a small number of drugs modulating mitophagy in intracerebral hemorrhage have been found thus far, most of which are in the preclinical stage and require further investigation, mitophagy is still a very valid and promising therapeutic target for intracerebral hemorrhage in the long run.
