Angiotensin II receptor-induced cardiac remodeling in mice without angiotensin II.
Cell surface receptors and their ligands cooperatively regulate physiological processes. The receptor activity is regulated positively when agonists bind and negatively when antagonists displace the agonists. Complete absence of a hormone should abrogate physiological and pathogenic functions regulated by the cognate receptor. However, awareness of the constitutive activity, the ability of nati...

متن کاملEffect of angiotensin II type 1 receptor blockade on cardiac remodeling in angiotensin II type 2 receptor null mice.
To clarify the possible involvement of uninhibited angiotensin II (Ang II) type 2 (AT(2)) receptor stimulation in the effects of an Ang II type 1 (AT(1)) receptor blocker, valsartan, we examined the cardiovascular remodeling induced by aortic banding with the use of wild-type (Agtr2+) and AT(2) receptor null (Agtr2-) mice. Aortic banding caused cardiac hypertrophy in Agtr2+ and Agtr2- mice to a...
متن کاملLocal angiotensin II aggravates cardiac remodeling in hypertension.
Angiotensin II (ANG II) contributes to hypertension, cardiac hypertrophy, fibrosis, and dysfunction; however, it is difficult to separate the cardiac effect of ANG II from its hemodynamic action in vivo. To overcome the limitations, we used transgenic mice with cardiac-specific expression of a transgene fusion protein that releases ANG II from cardiomyocytes (Tg-ANG II) and treated them with de...
متن کاملAngiotensin II induces inflammation leading to cardiac remodeling.
Hypertension, especially for elevated renin-angiotensin II (Ang II), induces cardiac fibrosis and remodeling. Ang II, acting via its receptors, causes both hemodynamic and nonhemodynamic effects. These effects trigger a series of inflammatory responses. Recent studies have demonstrated that hypertension stimulates infiltration of leukocytes into heart, and interaction among macrophages, T cells...
