WebFoam cells play an important role in the development of atherosclerosis. Current studies suggest that there are three sources of foam cells, including macrophages, VSMCs, and ECs (Chistiakov et al., 2024). Macrophage-derived foam cell. There are three processes of lipid metabolism in macrophages: cholesterol uptake, esterification, and efflux.

WebNational Center for Biotechnology Information WebAbstract. Macrophages play an important role in demyelination in multiple sclerosis (MS). Activated macrophages ingest myelin particles, thereby acquiring a foamy appearance. Foamy macrophages in MS lesions were described as being anti-inflammatory. Therefore, these cells might play a role in modulating the inflammatory state of an active lesion.

WebSep 14, 2024 · This overview is focusing on the role of macrophages in atherogenesis, which are at the same time a part of the inflammatory response, and also tightly linked to the foam cell formation, thus taking part in both crucial for atherogenesis processes.
WebJun 15, 1999 · Expression of lipoprotein lipase (LPL) by the macrophage has been proposed to promote foam cell formation and atherosclerosis, primarily on the basis of in vitro studies. LPL-deficient mice might provide a model for testing the role of LPL secretion by the macrophage in an in vivo system. Unfortunately, homozygous deficiency of LPL …
Foam cells, also called lipid-laden macrophages, are a type of cell that contain cholesterol. These can form a plaque that can lead to atherosclerosis and trigger heart attacks and stroke.
