Foam cell formation process
WebFoam cell formation is thought to be induced by Low Density Lipoproteins (LDL), including oxidized LDL (OxLDL) or minimally modified LDL (mmLDL). Understanding the molecular mechanisms involved in OxLDL- and mmLDL-induced foam cell formation is of fundamental importance for atherosclerosis and cardiovascular disease. WebSep 1, 2024 · The formation of foam cells is a complex process affected by various factors. Based on the current cognition, the main causes of foam cells generation are the excessive influx of modified LDL and the accumulation of cholesterol esters (CE) in intimal macrophages [22]. Circulating LDL is the major source of lipids that accumulates in the ...
