| Outline of Final Research Achievements |
Kawasaki disease (KD) is a pediatric systemic vasculitis. Despite the clinically transient nature of active inflammation in childhood albeit rare complications, KD has recently suggested to increased the incidence of ischemic heart disease in young adulthood. However, little is known about the pathogenesis of the post-inflammatory remodeling of the coronary arteries in chronic KD. In the present study, we performed histological analysis of coronary arteries in a KD-like vasculitis of rabbits. We found that post-inflammatory remodeling of coronary arteries is associated with predominant accumulation of proteoglycans in the lesion by proliferation of activated vascular smooth muscle cells, which may lead to progression to coronary arteriosclerosis.
