摘要

Necroptosis is a programmed form of cell death that has gained significant attention in the field of cardiovascular research due to its involvement in myocardial infarction (MI) and myocardial ischaemia-reperfusion (I/R) injury. Unlike apoptosis, necroptosis elicits a pro-inflammatory response, contributing to myocardial injury, fibrosis, and adverse remodelling. This review aims to provide an overview of the molecular mechanisms underlying necroptosis, with a particular focus on its role in myocardial I/R injury. Key regulatory proteins such as Receptor-interacting protein kinase 3 (RIPK3) and Mixed lineage kinase domain-like protein (MLKL) are central to the necroptotic process, mediating cell death and inflammation. The review discusses the potential of targeting necroptosis as a therapeutic strategy for managing cardiovascular diseases, particularly post-MI. The RIPK3-CaMKII-mitochondrial permeability transition pore (mPTP) pathway is identified as a critical signalling axis in necroptosis and its inhibition may offer protective benefits in myocardial injury. The review also considers the role of natural and chemical inhibitors and other genes in necroptosis regulation. Overall, targeting necroptosis represents a promising avenue for therapeutic intervention to mitigate cardiac injury, promote recovery, and improve long-term patient outcomes in cardiovascular diseases.
