摘要: 线粒体是细胞内重要的细胞器之一,调控多种细胞内信号通路,然而环境应激会导致线粒体堆积并产生大量错误折叠或未折叠蛋白,造成线粒体功能紊乱。目前研究发现多种由线粒体到细胞核的信号传导通路能够缓解线粒体应激反应,维持线粒体的正常功能状态。本综述就酿酒酵母中的逆行反应,哺乳动物细胞和线虫中的线粒体未折叠蛋白的分子机制及线粒体未折叠蛋白反应与线粒体自噬、天然免疫的相互关系进行重点介绍。

关键词: 线粒体; 逆行反应; 未折叠蛋白反应; 线粒体自噬

Abstract: Mitochondria,as one of important intracellular organelles,regulates many intracellular signaling pathways,but environmental stress can cause accumulation of large amounts of misfolded or unfolded proteins,resulting in mitochondrial dysfunction.Current studies have revealed that a variety forms of signaling pathway from mitochondria to nucleus which can alleviate mitochondrial stress reaction and maintain mitochondrial homeostasis.In this paper,we will lay emphasis on that the molecular mechanisms of retrograde reactions in Saccharomyces cerevisiae,mitochondrial unfolded protein response in mammalian cells and C.elegans,and the interaction between mitochondrial unfolded protein response and mitophagy,innate immunity.

Key words: mitochondria; retrograde response; unfolded protein response; mitophagy
