The study of mitochondrial dysfunction has become increasingly pivotal in elucidating the pathophysiology of various cerebral pathologies, particularly neurodegenerative disorders. Mitochondria are essential for cellular energy metabolism, regulation of reactive oxygen species (ROS), calcium homeostasis, and the execution of apoptotic processes. Disruptions in mitochondrial function, driven by factors such as oxidative stress, excitotoxicity, and altered ion balance, lead to neuronal death and contribute to cognitive impairments in several brain diseases. Mitochondrial dysfunction can arise from genetic mutations, ischemic events, hypoxia, and other environmental factors. This article highlights the critical role of mitochondrial dysfunction in the progression of neurodegenerative diseases and discusses the need for targeted therapeutic strategies to attenuate cellular damage, restore mitochondrial function, and enhance neuroprotection.
线粒体功能障碍的研究在阐明各种脑部疾病,尤其是神经退行性疾病的病理生理学方面变得越来越关键。线粒体对于细胞能量代谢、活性氧(ROS)调节、钙稳态以及凋亡过程的执行至关重要。由氧化应激、兴奋性毒性和离子平衡改变等因素驱动的线粒体功能破坏会导致神经元死亡,并在几种脑部疾病中导致认知障碍。线粒体功能障碍可能由基因突变、缺血事件、缺氧和其他环境因素引起。本文强调了线粒体功能障碍在神经退行性疾病进展中的关键作用,并讨论了采取针对性治疗策略以减轻细胞损伤、恢复线粒体功能和增强神经保护作用的必要性。
