Respuesta :
When cells in the artery take up LDL cholesterol (bad cholesterol) in an uncontrolled fashion, they become foam cells.
What is LDL cholesterol?
It is often called as the bad cholesterol because it collects in the walls of our blood vessels, raising the chances of health problems like a heart attack or stroke. Low-density lipoprotein is a tiny blob made up of an outer rim of lipoprotein with a cholesterol center.
What are foam cells?
These are formed through lipid accumulation that exceeds the homeostatic capacity of macrophages triggers lipid droplet formation, which results in the foamy appearance of these macrophages.
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 macrophages once they become oversaturated with LDLs.
Mostly smooth muscle cells (SMCs) are the abundant cells in human atherosclerotic lesions and are suggested to contribute at least 50% of atheroma foam cells.
Hence with the accumulation of LDL cholesterol the cells of the artery wall divide in an uncontrollable fashion, they become foam cells
