Failure to bridle inflammation spurs atherosclerosis

When a person develops a sore or a boil, it erupts, drawing to it immune system cells that fight the infection. Then it resolves and flattens into the skin, often leaving behind a mark or a scar. A similar scenario plays out in the blood vessels. However, when there is a defect in the resolutio...
