    摘要:

    线粒体动力学是指线粒体通过分裂和融合维持线粒体网络的动态平衡并为细胞提供能量。 在各种因素影响下,线粒体极易发生损伤,尤其是分裂异常导致其功能障碍与神经退行性疾病发生发展密切相关,而动力相关蛋白 1( dynamin-related protein1,Drp1) 是介导线粒体分裂的最关键蛋白。 研究表明,Drp1 在阿尔茨海默病 (Aizheimer’s disease,AD)中表达增加介导的线粒体碎片化与 AD 病理相互影响,加速了疾病进程。 本文通过对近几年关于 Drp1 蛋白结构、活性调控及其与 AD 相关的实验结论分析综合,为进一步明确 Drp1 与线粒体分裂和 AD 病理的关系、开发新的靶向线粒体动力学蛋白相关药物提供借鉴。

    Abstract:

    Mitochondrial dynamics refers to maintenance of the mitochondrial network and the provision of energy for cells during division and fusion. Mitochondria can be easily damaged by various factors, especially abnormal mitosis, which plays an important role in the occurrence and development of neurodegenerative diseases. Drp1 ( dynamin-related protein 1) is a crucial protein in mitochondrial division. Increased levels of Drp1 in Alzheimer’s disease (AD) mediate the interaction between mitochondrial fragmentation and AD pathology and accelerate the disease process. Here, we review the current understanding of Drp1 protein structure, activity regulation and its relationship with AD to clarify the relationship between Drp1, mitochondria and AD pathology. We also discuss the development of new drugs targeting mitochondrial kinetic proteins.
