Q

How is an Atheroma formed?

A

Endothelial lining injury
Lipid insudation
Cytokines release attracts monocytes
Lipid oxidation
Macrophages phagocytose LDLs
Platelet derived growth factor release causes smooth muscle proliferation
Smooth muscle cells migrate to endothelial cells
Macrophages become foam cells
Foam cells secrete cytokines which attract more inflammatory cells
Collagen and proteoglycan produced
