How does irritation or injury of endothelial cells lead to lowered LDL levels?
What will be an ideal response?
Irritation or injury stimulates the inflammatory response and calls the white blood cells to action, the leukocytes. Leukocytes called monocytes are attracted to vascular adhesion molecules on the endothelial cells and penetrate the vascular wall. Once inside, these monocytes transform into macrophages that eat modified LDL (low density lipoprotein), otherwise known as "bad cholesterol."
