研究概述

Research Description

线粒体是负责能量供应的细胞器，也是细胞凋亡的关键执行者和炎症反应的重要参与者。线粒体功能紊乱和损伤积累是衰老和衰老相关疾病发生的重要诱因之一。我们实验室专注于理解线粒体质量控制和稳态维持机制，以及这些机制在退行性疾病和衰老中的作用。我们利用酵母,细胞,小鼠等模型,整合遗传,生化,化学生物学等手段,研究以下重要问题: 1. 线粒体质量控制体系,包括蛋白质质量控制和线粒体自噬,的分子机理及其生物学功能。2.线粒体疾病,尤其是呼吸链损伤相关神经退行性疾病,的致病机理及治疗靶点开发。3.线粒体损伤与慢性炎症和退行性病变的相互关系。

Mitochondrion is the powerhouse of the cell and a key player in apoptosis and inflammation. Mitochondrial dysfunction is a driving force of aging and aging-related degenerative diseases. We exploit yeast, cultured cell, and mouse models to uncover mechanisms surveying mitochondrial quality and maintaining mitochondrial homeostasis. We focus on the following questions: 1. mitochondrial quality control mechanisms, including protein quality control and mitophagy; 2. the pathological mechanisms and therapeutic targets for mitochondrial diseases; 3. the relationship between mitochondrial damage, chronic inflammation, and degenerative diseases.
