WebAug 7, 2024 · Macrophages serve as the main source of foam cells after they penetrate the endothelial barrier and accumulate in the arterial intima media in response to the pro-inflammatory activation of endothelial cells (ECs) [ 1 ]. A small part of foam cells originates from ECs and vascular smooth muscle cells (VSMCs). WebFoam cells are a rich source of proinflammatory mediators and there is strong evidence that support a central role for inflammation in all phases of the atherosclerotic process which includes the activation of numerous different cell types and chemoattractant agents such as proinflammatory cytokines, macrophages, and T lymphocytes as well as mast …
