title: Receptors and their classification: focus on angiotensin II and the AT2 receptor.
abstract: Angiotensin II mediates its effects through angiotensin receptors. The use of specific angiotensin receptor ligands and the cloning of these receptors allows their classification. So far, the AT1, AT2 and atypical angiotensin II receptors are recognised. The AT1 receptor is responsible for the classical effects of the renin-angiotensin system such as vasoconstriction, renal salt and water retention, central osmo-control and stimulation of cell growth. The function of the AT2 receptor is far from clear but this receptor appears to be important in fetal development, cell growth inhibition and differentiation processes. This review describes the angiotensin receptors and focuses on the possible functions of the AT2 receptor.
