WebFoam cells are white blood cells that consume invaders to try to get rid of them. In this case, they consume cholesterol and thus appear foamy. Continued foam cell activity causes further damage to your endothelium. Plaque growth. Dead foam cells and other debris continue building up. So, the fatty streak turns into a larger piece of plaque. 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 …
