Abstract
Increased understanding of the contribution of angiotensin peptides to the physiologic control of arterial pressure and cardiovascular regulation has been made possible with the introduction of agents that either inhibit the activity of angiotensins forming enzymes or block the action of the peptides at their specific receptor subtypes. This review highlights some of the lessons that have been learned from the study of the actions of angiotensin-(1-7) and its interrelationship with other vasodilator mechanisms that modulate the control systems that determine blood pressure and tissue perfusion. The studies suggest that the reninangiotensin system acts as a humoral mechanism for blood pressure control through the generation of several distinct forms of angiotensin peptides that may bind to diverse receptor subtypes.
