线粒体是负责细胞能量产生的动态细胞器。此外,调节能量稳态,线粒体负责钙稳态、信号传递以及在损伤和病理情况下细胞存活的命运。越来越多的报道表明,线粒体在生理和病理条件下的神经病理学、神经变性和免疫激活中具有多种作用。线粒体功能障碍发生在脑损伤的初始阶段,涉及氧化应激、炎症、线粒体生物能学缺陷、生物发生、转运和自噬。因此,开发保护线粒体的靶向治疗方法可能会改善创伤性脑损伤(TBI)和脑内出血(ICH)后的功能结局。在这篇综述中,我们总结了与TBI和ICH相关的线粒体功能障碍,包括所涉及的机制,并讨论了治疗方法,特别强调过去和目前的临床试验。
Mitochondria are dynamic organelles responsible for cellular energy production. Besides, regulating energy homeostasis, mitochondria are responsible for calcium homeostasis, signal transmission, and the fate of cellular survival in case of injury and pathologies. Accumulating reports have suggested multiple roles of mitochondria in neuropathologies, neurodegeneration, and immune activation under physiological and pathological conditions. Mitochondrial dysfunction, which occurs at the initial phase of brain injury, involves oxidative stress, inflammation, deficits in mitochondrial bioenergetics, biogenesis, transport, and autophagy. Thus, development of targeted therapeutics to protect mitochondria may improve functional outcomes following traumatic brain injury (TBI) and intracerebral hemorrhages (ICH). In this review, we summarize mitochondrial dysfunction related to TBI and ICH, including the mechanisms involved, and discuss therapeutic approaches with special emphasis on past and current clinical trials.
