[Unexpected properties of angiotensin mediated by the AT2 receptor: possible therapeutic implications]
Abstract:
The renin-angiotensin-aldosterone system plays an important role in the regulation of electrolyte balance, body fluid volume and blood pressure. As yet, angiotensin II has been ascribed actions mediated by first type of receptors (AT1) such as increased blood pressure, antinatriuretic effect, cell proliferation. Since several years studies have been conducted on the role of second type receptor (AT2) through which angiotensin manifests its effects opposing those resulting from stimulation of type 1 receptor. They include: release of bradykinin and nitric oxide, vasodilation, natriuretic and antiproliferative effects. Blockade of the function of this receptor causes excessive reaction induced by action exerted on AT1 receptor.
