Fragment crystallizable γ receptors (FcγRs) are receptors for immunoglobulin G (IgG). Most of them are expressed on the surface of immune cells, and exert relevant biological functions by binding to the Fc region of IgG to form immune complexes. FcγRs are classified into activating and inhibitory types, which exert similar or opposite functions in different cells. In cardiovascular disease research, multiple studies have found that FcγRs expressed on immune and innate cells participate in the occurrence and development of cardiovascular-related diseases such as myocardial infarction, atherosclerosis, and hypertension by activating cell signaling and stimulating the secretion of different cytokines. This article reviews the classification and functions of FcγRs, as well as the research progress on FcγRs in cardiovascular diseases, with the aim of providing new ideas and methods for the prevention and treatment of cardiovascular diseases.
