Foam cell formation process
WebMacrophage foam cell formation represents one of the earliest stages of lesion development, ... Extracellular matrix glycoproteins within the intima contribute to this process by retaining apoB-containing lipoproteins and by modulating the activity of enzymes, including secretory phospholipase A2 group (PLA2G2A), PLA2G5, PLA2G7 … WebAtherosclerosis (AS) is a common cardiovascular disease and remains the leading cause of death in the world. It is generally believed that the deposition of foam cells in the arterial wall is the main cause of AS. Moreover, promoting cholesterol efflux and enhancing the ability of reverse cholesterol transport (RCT) can effectively inhibit the formation of …

WebApr 13, 2024 · Since the formation of foam cells is a hallmark in the initial stage of atherosclerosis, tremendous efforts have been made to unveil the regulatory pathways and mechanisms associated with the process. Foam cells are the incorporative effects of lipid uptake, lipid efflux, and cholesterol esterification. WebApr 13, 2024 · Foam cells undergo diverse pathways of programmed cell death including apoptosis, autophagy, necroptosis, and pyroptosis, contributing to the necrotic cores of …
WebJul 26, 2024 · Furthermore, dyslipidaemia causes inflammatory responses and foam cell formation. Mechanistic target of rapamycin (mTOR) signalling is a key regulator of diverse cellular processes, including cell metabolism and cell fate. mTOR complex 1 (mTORC1) is involved in lipid metabolism and immune responses in the body. WebFormation. Several conditions are needed to produce foam: there must be mechanical work, surface active components (surfactants) that reduce the surface tension, and the …
Foam cells are formed when circulating monocyte-derived cells are recruited to the atherosclerotic lesion site or fat deposits in the blood vessel walls. Recruitment is facilitated by the molecules P-selectin and E-selectin , intercellular adhesion molecule 1 ( ICAM-1 ) and vascular cell adhesion … See more 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. Foam cells are fat … See more Foam cell formation is triggered by a number of factors including the uncontrolled uptake of modified low density lipoproteins (LDL), the upregulation of cholesterol esterification and the impairment of mechanisms associated with cholesterol … See more Foam cell degradation or more specifically the breakdown of esterified cholesterols, is facilitated by a number of efflux receptors and pathways. Esterified cholesterol from cytoplasmic liquid … See more Foam cells may form around leaked silicone from breast implants. Lipid-laden alveolar macrophages, also known as pulmonary foam cells, are seen in bronchoalveolar lavage specimens in some respiratory diseases. See more Low-density lipoprotein (LDL) cholesterol (LDL-C — also known as “bad” cholesterol) and particularly modified forms of LDL cholesterol such as oxidized, glycated, or acetylated LDL, is contained by a foam cell - a marker of atherosclerosis. … See more Foamy macrophages are also found in diseases caused by pathogens that persist in the body, such as Chlamydia, Toxoplasma, or Mycobacterium tuberculosis See more 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.
