线粒体功能障碍是各种神经退行性疾病的显著特征。对线粒体的显着动态性质的更深入理解,其特征是裂变和融合的微妙平衡,有助于丰富最近一波新的研究,证明神经退行性疾病中的线粒体动力学异常。本文综述了阿尔茨海默病、帕金森病、肌萎缩侧索硬化症和亨廷顿舞蹈病的线粒体功能障碍和异常线粒体动力学,并讨论了这些异常线粒体动力学如何导致线粒体和神经元功能障碍。我们认为,异常的线粒体动力学是一个关键的共同途径,介导或放大线粒体功能障碍和神经元功能障碍的过程中的神经变性。
Mitochondrial dysfunction is a prominent feature of various neurodegenerative diseases. A deeper understanding of the remarkably dynamic nature of mitochondria, characterized by a delicate balance of fission and fusion, has helped to fertilize a recent wave of new studies demonstrating abnormal mitochondrial dynamics in neurodegenerative diseases. This review highlights mitochondrial dysfunction and abnormal mitochondrial dynamics in Alzheimer disease, Parkinson disease, amyotrophic lateral sclerosis, and Huntington disease and discusses how these abnormal mitochondrial dynamics may contribute to mitochondrial and neuronal dysfunction. We propose that abnormal mitochondrial dynamics represents a key common pathway that mediates or amplifies mitochondrial dysfunction and neuronal dysfunction during the course of neurodegeneration.
