Foam macrophage
WebSep 1, 2024 · However, when the macrophages swallow too much LDL, the balance of “input” and “output” of lipids in macrophages will be disrupted, which triggers the formation of foam cells (Fig. 1), thereby causing the buildup of plaque [7, 8]. Macrophages, as the key mediators of inflammatory response, affect the progression of atherosclerosis. WebSep 23, 2013 · Macrophage foam cells play a critical role in the occurrence and development of atherosclerosis. The generation of these cells is associated with imbalance of cholesterol influx, esterification and efflux. CD36 and scavenger receptor class A (SR-A) are mainly responsible for uptake of lipoprotein-derived cholesterol by macrophages.
