心肌缺血再灌注损伤中的线粒体相关细胞器串扰

细胞器损伤是导致心肌缺血再灌注损伤的重要因素.这种损伤会导致线粒体及相关细胞器的功能改变.线粒体与其他细胞器的串扰同样影响心脏缺血再灌注损伤的发生发展,例如线粒体相关内质网膜使得线粒体和内质网"无缝连接",调节线粒体和内质网之间的细胞器和代谢物(包括离子、脂质和蛋白质)交换,从而影响心肌缺血再灌注损伤.然而,线粒体与相关细胞器串扰是触发心肌缺血再灌注损伤的关键因素,目前相关报道有限.因此,该文阐述了线粒体与内质网、溶酶体和细胞核串扰在心肌缺血再灌注损伤中的作用,旨在为靶向线粒体与其他细胞器的串扰治疗心肌缺血再灌注损伤的研究提供一定的理论依据.
Mitochondria-associated organelle crosstalk in myocardial ischemia/reperfusion injury
Damage to organelles plays a significant role in myocardial ischemia/reperfusion injury,which results in the dysfunction of mitochondria and other related organelles.The communication between mitochondria and other organ-elles can also affect the development of myocardial ischemia/reperfusion injury.For instance,the mitochondria-associated endoplasmic reticulum membrane provides a"seamless connection"and regulates the exchange of organelles and metabolites(such as ions,lipids and proteins)between the mitochondria and the endoplasmic reticulum,which subse-quently affects myocardial ischemia/reperfusion injury.However,there is a lack of studies regarding the interaction be-tween mitochondria and related organelles,which is a critical component in triggering myocardial ischemia/reperfusion inju-ry.Therefore,this article describes the role of mitochondrial crosstalk with endoplasmic reticulum,lysosomes and nuclei in myocardial ischemia/reperfusion injury,and aims to provide a theoretical basis for targeting mitochondrial crosstalk with other organelles in the treatment of myocardial ischemia/reperfusion injury.
