Cardiac function is determined by the dynamic equilibrium of various cell types and the extracellular matrix that composes the heart. Cardiovascular diseases (CVDs), especially atherosclerosis and myocardial infarction, are often accompanied by cell death and acute/chronic inflammatory reactions. Caspase‐dependent pyroptosis is characterized by the activation of pathways leading to the activation of NOD‐like receptors, especially the NLRP3 inflammasome and its downstream effector inflammatory factors interleukin (IL)‐1β and IL‐18. Many studies in the past decade have investigated the role of pyroptosis in CVDs. The findings of these studies have led to the development of therapeutic approaches based on the regulation of pyroptosis, and some of these approaches are in clinical trials. This review summarizes the molecular mechanisms, regulation and cellular effects of pyroptosis briefly and then discusses the current pyroptosis studies in CVD research.
P62 is a multidomain protein that contains different kinds of protein–protein interaction domains, including an N-terminal PB1 domain, a ZZ-type zinc finger domain, a nuclear localization signal (NLS), an export motif (NES), the LC3-interacting region (LIR), the KEAP1-interacting region (KIR), and a C-terminal Ub-associated domain (UBA). p62 is involved in the degradation of protein aggregates and cytoplasmic bodies via selective autophagy through its PB1, LIR, and UBA domains to maintain homeostasis in the cell. Moreover, NES, NLS, KIR, and ZZ domains have been found to be linked to ubiquitinated protein degradation by autophagy. Therefore, understanding the functional domains of p62 is important. In this review, we attempt to expound the mechanism of connection between p62 and selective autophagy to illustrate how the domains of p62 regulate selective autophagy, and to provide a new direction and perspective on selective autophagy research.
