Foam cell formation process
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 … WebA foam is produced by trapping millions of tiny gas bubbles in a liquid (whipped egg white) or a solid (marshmallow). Whisking water and air produces hundreds of bubbles but they soon ‘pop’, leaving only water …

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. WebOct 29, 2024 · The formation of foam cells occurs when macrophages engulf an excess of many types of LDL, including oxidized LDL (OxLDL) and minimally modified LDL (mmLDL), which result in the death of the...
WebJan 9, 2024 · In the present study, we investigated whether LPC can induce foam cell formation through an analysis of LD biogenesis and determined whether the cell signaling involved in this process is mediated by the inflammasome activation pathway in human endothelial cells and monocytes. Our results showed that LPC induced foam cell … 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 ...
WebThe formation and accumulation of foam cells is a critical process of intimal lipid deposition during atherosclerosis (Maguire et al., 2024), which plays an important role in all stages of atherosclerotic lesion development, from the initial lesion to the advanced plaque.
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.
