Classical DCs associated with protection against atherosclerosis

Atherosclerosis, commonly referred to as "hardening of the arteries," is a major risk factor for heart attack and stroke. The cause of atherosclerosis is not well understood but, for some time, chronic inflammatory immune responses have been implicated in driving disease pathology. Now, a new study, published online on November 10th by Cell Press from the journal Immunity, identifies a type of immune cell that is not associated with promoting disease, but with protection against atherosclerosis.
