摘要: 心脏缺血再灌注(ischemia-reperfusion,I/R)损伤是心脏疾病中常见并发症,其发生机制复杂且尚未完全阐明。线粒体质量控制(mitochondrial quality control,MQC)是维持心肌细胞正常功能和适应能力的关键过程。MQC系统参与调节线粒体生物合成、线粒体动力学以及自噬环节,保护心肌细胞免受I/R损伤的影响。目前,MQC成为心脏I/R损伤的新型靶向治疗策略。本文通过概述MQC与心脏I/R损伤之间的联系及近期研究机制进展,旨在提供新的思路和研究方向,为心脏疾病的治疗和预防提供理论依据。Abstract: Cardiac ischemia-reperfusion(I/R) injury is a prevalent complication of cardiac diseases, mechanism of which remains intricate and incompletely understood. Mitochondrial quality control(MQC) is a key process in maintaining the normal function and adaptability of cardiomyocytes. The MQC system orchestrates mitochondrial biosynthesis, dynamics, and autophagy, affording protection against I/R injury. At present, MQC has become a new targeted treatment strategy for cardiac I/R injury. By summarizing the relationship between MQC and cardiac I/R injury and the recent research mechanism, this paper aims to provide new ideas and research directions, and provide theoretical basis for the treatment and prevention of heart diseases.
