Macrophage Cyclooxygenase-2 Protects Against Development of Diabetic Nephropathy

Diabetic nephropathy (DN) is characterized by increased macrophage infiltration, and proinflammatory “M1” macrophages contribute to development of DN. Previous studies by us and others have reported that macrophage cyclooxygenase-2 (COX-2) plays a role in polarization and maintenance of a macrophage tissue reparative “M2” phenotype. We examined the effects of macrophage COX-2 on development of DN in type I diabetes.
