Antioxidative, Antinitrative, and Vasculoprotective Effects of a Peroxisome Proliferator–Activated Receptor-γ Agonist in Hypercholesterolemia

Abstract

The PPARgamma agonist rosiglitazone exerted a significant vascular protective effect in hypercholesterolemic rabbits, most likely by attenuation of oxidative and nitrative stresses. The endothelial protective effects of PPARgamma agonists may reduce leukocyte accumulation in vascular walls and contribute to their antiatherosclerotic effect.
