Amyotrophic lateral sclerosis (ALS) is a devastating neurodegenerative disease characterized by the progressive loss of motor neurons, for which current treatment options are limited. Recent studies have shed light on the role of mitochondria in ALS pathogenesis, making them an attractive therapeutic intervention target. This review contains a very comprehensive critical description of the involvement of mitochondria and mitochondria-mediated mechanisms in ALS. The review covers several key areas related to mitochondria in ALS, including impaired mitochondrial function, mitochondrial bioenergetics, reactive oxygen species, metabolic processes and energy metabolism, mitochondrial dynamics, turnover, autophagy and mitophagy, impaired mitochondrial transport, and apoptosis. This review also highlights preclinical and clinical studies that have investigated various mitochondria-targeted therapies for ALS treatment. These include strategies to improve mitochondrial function, such as the use of dichloroacetate, ketogenic and high-fat diets, acetyl-carnitine, and mitochondria-targeted antioxidants. Additionally, antiapoptotic agents, like the mPTP-targeting agents minocycline and rasagiline, are discussed. The paper aims to contribute to the identification of effective mitochondria-targeted therapies for ALS treatment by synthesizing the current understanding of the role of mitochondria in ALS pathogenesis and reviewing potential convergent therapeutic interventions. The complex interplay between mitochondria and the pathogenic mechanisms of ALS holds promise for the development of novel treatment strategies to combat this devastating disease.
肌萎缩侧索硬化症(ALS)是一种破坏性的神经退行性疾病,其特征是运动神经元的进行性丧失,目前的治疗选择有限。最近的研究揭示了线粒体在 ALS 发病机制中的作用,使它们成为有吸引力的治疗干预靶点。这篇综述对线粒体及其介导的机制在 ALS 中的作用进行了非常全面的批判性描述。该综述涵盖了与 ALS 中线粒体相关的几个关键领域,包括线粒体功能障碍、线粒体生物能学、活性氧、代谢过程和能量代谢、线粒体动力学、周转率、自噬和线粒体自噬、线粒体转运受损以及细胞凋亡。该综述还强调了研究各种针对 ALS 治疗的线粒体靶向疗法的临床前和临床研究。这些策略包括改善线粒体功能的方法,如使用二氯乙酸、生酮和高脂肪饮食、乙酰肉碱和线粒体靶向抗氧化剂。此外,还讨论了抗细胞凋亡剂,如靶向 mPTP 的米诺环素和雷沙吉兰。本文旨在通过综合当前对线粒体在 ALS 发病机制中的作用的认识,并综述潜在的集中治疗干预措施,为确定有效的线粒体靶向治疗 ALS 提供参考。线粒体与 ALS 致病机制之间的复杂相互作用为开发治疗这种毁灭性疾病的新治疗策略提供了希望。
