Aldosterone secretion and action

Research output: Chapter in Book/Report/Conference proceedingChapter (Book)Otherpeer-review


Aldosterone activates the mineralocorticoid receptor (MR), a member of the nuclear receptor superfamily. Aldosterone synthesis/secretion is primarily regulated by angiotensin II nd potassium as part of two parallel feedback loops. The MR is unique, being the receptor for two physiologic ligands: aldosterone and cortisol. Aldosterone selectivity of the MR in epithelial tissues is conferred by 11 hydroxysteroid dehydrogenase type II. Activation of the MR in nonepithelial tissue is associated with a proinflammatory, profibrotic response connected with the adverse cardiovascular outcome, seen with aldosterone excess.
