The Role of Aldosterone in Vascular Permeability in Diabetes.

ABSTRACT: More than 30% of diabetic patients develop dermatopathies linked to inflammation and increased vascular permeability. Considering the role of the renin-angiotensin-aldosterone system (RAAS) in diabetic complications, this study examined whether aldosterone (ALDO) and the mineralocorticoid receptor (MR) contribute to diabetes-related skin microangiopathy. Vascular permeability was measured in normoglycemic rats and insulin-dependent (streptozotocin-induced) diabetic rats. The expression of MR, 11β-hydroxysteroid dehydrogenase type 2 (HSD11β2), vascular endothelial growth factor (VEGF), von Willebrand factor (vWF), and the tight junction protein ZO-1 was determined by PCR and immunohistochemistry. Diabetic rats received the MR antagonist eplerenone (EPL, 100 mg/kg) for 10 days. Additionally,
