abstract：:11beta-hydroxysteroid dehydrogenases (11betaHSDs) catalyze interconversion of 11-hydroxy-glucocorticoids with inactive 11-keto metabolites. In blood vessel walls, loss of 11betaHSD1 is thought to reduce local glucocorticoid concentrations, reducing the progression of atheroma and enhancing angiogenesis. Conversely, on...
