Blockade of Central Angiotensin II AT1 Receptor Protects the Brain from Ischemia/Reperfusion Injury in Normotensive Rats
Background: Stroke is the third leading cause of invalidism and death in industrialized countries. There are conflicting reports about the effects of Angiotensin II on ischemia-reperfusion brain injuries and most data have come from chronic hypertensive rats. In this study, hypotensive and non-hypotensive doses of candesartan were used to investigate the effects of angiotensin II AT1 receptor b...
متن کاملAngiotensin II type 1 receptor blockade prevents alcoholic cardiomyopathy.
BACKGROUND Activation of the renin-angiotensin system (RAS) may contribute to the development of alcoholic cardiomyopathy. We evaluated the effect of angiotensin II (Ang II) type 1 receptor (AT1) blockade on the development of alcoholic cardiomyopathy. METHODS AND RESULTS We serially evaluated left ventricular (LV) and cardiomyocyte function and the RAS over 6 months in 3 groups of instrument...
متن کاملNeural and hypotensive effects of angiotensin II receptor blockade.
Angiotensin II participates in the neural regulation of the heart and circulation at both central and peripheral sites. To explore the role of endogenous angiotensin II in blood pressure regulation, we conducted a randomized double-blind crossover trial in nine young healthy men (aged 33+/-3 [mean+/-SE] years) studied in the absence of salt restriction, comparing the effect of 1 week treatment ...
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 کاملAngiotensin II type 2 receptor expression after vascular injury: differing effects of angiotensin-converting enzyme inhibition and angiotensin receptor blockade.
It has been suggested that the effects of angiotensin II type 1 receptor (AT1R) blockers are in part because of angiotensin II type 2 receptor (AT2R) signaling. Interactions between the AT2R and kinins modulate cardiovascular function. Because AT2R expression increases after vascular injury, we hypothesized that the effects on vascular remodeling of the AT1R blocker valsartan and the ACE inhibi...
