Organelle damage is a significant contributor to myocardial ischemia/reperfusion (I/R) injury. This damage often leads to disruption of endoplasmic reticulum protein regulatory programs and dysfunction of mitochondrial energy metabolism. Mitochondria and endoplasmic reticulum are seamlessly connected through the mitochondrial-associated endoplasmic reticulum membrane (MAM), which serves as a crucial site for the exchange of organelles and metabolites. However, there is a lack of reports regarding the communication of information and metabolites between mitochondria and related organelles, which is a crucial factor in triggering myocardial I/R damage. To address this research gap, this review described the role of crosstalk between mitochondria and the correlative organelles such as endoplasmic reticulum, lysosomal and nuclei involved in reperfusion injury of the heart. In summary, this review aims to provide a comprehensive understanding of the crosstalk between organelles in myocardial I/R injury, with the ultimate goal of facilitating the development of targeted therapies based on this knowledge.
细胞器损伤是心肌缺血/再灌注(I/R)损伤的重要原因。这种损伤通常会导致内质网蛋白调节程序的中断和线粒体能量代谢的功能障碍。线粒体和内质网通过线粒体相关内质网膜(MAM)无缝连接,MAM 是细胞器和代谢物交换的关键部位。然而,关于线粒体和相关细胞器之间信息和代谢物的交流仍缺乏报道,这是触发心肌 I/R 损伤的关键因素。为了解决这一研究空白,本综述描述了线粒体与内质网、溶酶体和核等相关细胞器之间的相互作用在心脏再灌注损伤中的作用。总之,本综述旨在全面了解心肌 I/R 损伤中细胞器之间的相互作用,以期基于这一知识开发靶向治疗方法。
