【摘要】 线粒体形态和功能的异常与多种疾病的发生密切相关。线粒体通过不断的分裂和融合,维持线粒体网络的动态平衡,该过程称为线粒体动力学,是维持线粒体形态、分布和数量,保证细胞稳态的重要基础。此外,机体还通过线粒体自噬过程降解胞内功能异常的线粒体,维持线粒体稳态。线粒体动力学与线粒体自噬二者之间可相互调控,共同维持线粒体质量平衡。探讨线粒体动力学和线粒体自噬的调控机制对揭示多种疾病发生的分子机制、开发新的靶向线粒体动力学蛋白或线粒体自噬调控蛋白的药物具有重要意义。本文从线粒体动力学与线粒体自噬出发,对线粒体动力学调控机制、线粒体自噬及其发生机制以及二者的相互作用关系、线粒体动力学及线粒体自噬与人类相关疾病等方面作一综述。更多还原

【Abstract】 The abnormality of mitochondrial morphology and function is closely related to the pathogenesis of many diseases. Mitochondrial fusion-fission dynamics are critical to maintain normal morphology, distribution and quantity of mitochondria, and ensure the normal activity of cells. In addition, mitochondrial autophagy(mitophagy) plays an important role in maintaining mitochondrial quality by degrading aging or damaged mitochondria. Many previous studies showed that mitochondrial dynamics and mitophagy can regulate each other to sustain mitochondrial network homeostasis. Clarifying regulatory mechanisms of mitochondrial dynamics and mitophagy is of great significance for revealing the molecular mechanism of various diseases and for the development of new drugs targeting mitochondrial dynamics proteins or mitophagy regulatory proteins. This review focuses on the role of mitochondrial dynamics and mitophagy in mitochondrial quality control, regulatory mechanism, the interplay between those two processes, and their roles in human-related diseases.更多还原
