Summary
Angiotensin (Ang) II exerts major influences on the heart and blood vessels via its effects on systemic hemodynamics and blood volume as well as structural effects. The major cardiovascular actions of Ang II have been reported to be mediated by the type 1 Ang II receptor or AT1 receptor. Recently, we have cloned a second receptor subtype known as AT2 receptor. The existence and differential expression of two different subtypes of Ang II receptors in the human myocardium and the reciprocal expression of AT1 and AT2 receptor in myocardial infarction and cardiac failure suggest pathophysiological importance of these receptors in cardiovascular disease and remodeling. Moreover, documented evidences suggest that the cellular composition of the heart and blood vessels is determined by the balance between apoptotic cell death (programmed cell death) and cell survival, and the unbalanced cell death plays a critical role in the pathogenesis of cardiovascular diseases and remodeling. Our successful clonings of AT2 receptor cDNAs have provided a unique opportunity to study the biology and function of this receptor. Indeed, in our previous experiments, we have demonstrated that AT2 receptor activates tyrosine phosphatase(s) and inhibits mitogen-activated protein kinase (MAPK) activation, thereby exerting the proapoptotic and antigrowth effects in several cells including cardiomyocytes and vascular smooth muscle cells. These antagonistic actions may contribute to the pathogenesis of cardiovascular diseases and remodeling.
