WebApr 24, 2024 · LDL-laden macrophages become foam cells that promote inflammation and further the development of atherosclerotic plaques. The plaques narrow the artery and can become unstable. Plaques that rupture can activate blood clotting and block blood flow to the brain or heart, resulting in a stroke or heart attack. WebMay 23, 2024 · A foam is a substance made by trapping air or gas bubbles inside a solid or liquid. Typically, the volume of gas is much larger than that of the liquid or solid, with thin films separating gas pockets. Another definition of foam is a bubbly liquid, particularly if the bubbles, or froth, are undesirable.

WebAtherosclerosis is an inflammatory disease initiated by endothelial activation, in which lipoprotein, cholesterol, extracellular matrix, and various types of immune and non-immune cells are accumulated and formed into plaques on the arterial wall suffering from disturbed flow, characterized by low and oscillating shear stress. Foam cells are a major cellular … WebFoam cells, typically classified as a type of macrophage, persist in plaques, promoting disease progression. While macrophage clearance of lipoproteins is likely to be beneficial at the outset of this immune response, there is little negative feedback of uptake and thus these cells become grossly engorged with lipids.
