Efferocytosis is considered the key to eliminate apoptotic cells (ACs) under physiological and pathological conditions in vivo, mainly through different types of macrophages to achieve this process. Especially, tissue-resident macrophages (TRMs) are very significant for inflammation regression and maintenance of homeostasis in vivo. Abnormal efferocytosis will lead to the accumulation of ACs and the release of a variety of pro-inflammatory factors, which mediates the occurrence of many inflammatory diseases, including atherosclerosis (AS). AS is a chronic inflammatory vascular disease with the participation of the immune system. Defective efferocytosis will accelerate the progress of AS to a certain extent. Therefore, it is of great significance to understand the mechanism of efferocytosis and realize the prevention and treatment of AS through efferocytosis. In this review, we will briefly describe the specific process of efferocytosis, deeply discuss the possible molecular mechanism of impaired efferocytosis promoting the development of AS, and summarize the ways to prevent and treat AS through efferocytosis intervention therapy.
