The renin-angiotensin system has a central role in the regulation of blood pressure and water balance. It is also a main target in the treatment of hypertension. Angiotensin II has 2 major receptors, the type 1 (AT1R) and the type 2 receptor (AT2R), both coupled to G proteins. Adverse vascular remodeling observed in cardiovascular diseases is attributed to AT1R, and a large number of relatively...
BACKGROUND We have previously shown that angiotensin II type 2 receptor (AT(2)R) stimulation causes endothelium-dependent vasodilation that does not desensitize after chronic angiotensin II type 1 receptor (AT1R) blockade, suggesting a role for AT2R in antihypertensive treatment. METHODS AND RESULTS We recorded mean arterial pressure (MAP) and investigated AT2R by Western blot analysis, immun...
Angiotensin II (Ang II) is the most dominant effector component of renin-angiotensin system (RAS) that generally acts through binding to two main classes G protein–coupled receptors, namely Ang subtype 1 receptor (AT1R) and angiotensin 2 (AT2R). Despite some controversial reports, activation AT2R antagonizes effects on AT1R. Studying signaling, function, its specific ligands in cell culture or ...
During normal pregnancy the renin-angiotensin system is activated, yet pregnant women are resistant to the pressor effects of angiotensin II. Our aim was to determine the role of the angiotensin type 2 receptor (AT2R) in the regulation of arterial pressure, natriuresis, and immune cell infiltration during pregnancy. Mean arterial pressure was measured via telemetry, and flow cytometry was used ...
The role of the angiotensin II type 2 receptor (AT2R) in cardiovascular physiology remains elusive. We have developed an in vivo lentiviral vector-mediated gene transfer system to study the physiological functions of the AT2R. Our objectives in this study were to determine whether the AT2R influences cardiac hypertrophy and myocardial and perivascular fibrosis in a nongenetic rat model of hyper...
INTRODUCTION The rennin-angiotensin system (RAS) plays a central role in the regulation of sodium metabolism, vascular tone, blood pressure, renal hemodynamics, and vascular modeling and is activated by hyperglycemiaObjectives: In the present study the influence of AT2R -1332 G:A polymorphism on the risk of T2DM and its complications in a population from Western Iran has been investigated. PA...
BACKGROUND Vasoconstrictive, proliferative and oxidative effects of angiotensin II (Ang II) are mediated by Ang II type 1 (AT1) receptors. The effects of Ang II via the Ang II type 2 (AT2) receptor subtype (AT2R) are less well defined. Growing evidence shows the existence of cross-talk between the Ang II receptor subtypes, which is revealed by AT1R blockade. Hence, under certain conditions, AT2...
This study aims to understand the special expression patterns of angiotensin-II receptor (AT1R and AT2R) in nodose ganglia and nucleus of tractus solitary of baroreflex afferent pathway and their contribution in sex difference of neurocontrol of blood pressure regulation. In this regard, action potentials were recorded in baroreceptor neurons (BRNs) using whole-cell patch techniques; mRNA and p...
