Background: The vascular function of Angiotensin II-type-2 receptors in adults is controversial. We sought their location and function in mouse aortic rings at young and old mice. Materials and Methods: Male C57Bl mice (aged 4 and 14 months) were killed by CO2. The descending thoracic aorta was cleaned and dissected into rings. Aortic rings were mounted in Krebs’ solution at 37 °C an...

introduction: renin angiotensin system has an important role in blood pressure and renal functions. active angiotensin-converting enzyme 2 converts angiotensin i into angiotensin-(1-7) which is a vasodilator hormone and interacts with nitric oxide changes as well as other angiotensin ii receptors. in this study we evaluated the role of mas receptor antagonist (a779) and renal perfusion pressure...

Angiotensin converting enzyme-2 (ACE2) receptors mediate the entry into the cell of three strains of coronavirus: SARS-CoV, NL63 and SARS-CoV-2. ACE2 receptors are ubiquitous and widely expressed in the heart, vessels, gut, lung (particularly in type2 pneumocytes and macrophages), kidney, testisand brain. ACE2 is mostly bound to cell membranes and only scarcely present in the circulation in a s...
angiotensin-ii is a multifunctional hormone that regulates blood pressure, plasma volume, neuronal functions, electrolyte balance, thrust and various other vital mechanisms. it acts through its receptors at 1 and at 2 . the involvement of angiotensin-ii and its receptors in cognition is still ambiguous. therefore, the present study was designed to investigate the effect of angiotensin-ii (2 μg/...
Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...

Objective(s): Considering the lack of information, the effects of mild endurance exercise plus blood flow restriction (BFR) on electrocardiographic parameters, hypertrophy index, and expression of angiotensin II receptors type 1 (AT1R) and type 2 (AT2R) and apelin receptor (APJ) were assessed in hearts of old male rats.Materials and Methods: Animal were grouped as control (CTL), Sham (Sh), lowe...
Background: The renal sympathetic nerve activity (RSNA) is enhanced in renal failure. Paraventricular nucleus in hypothalamus is an important central site to regulate sympathetic activity. There are angiotensin II (Ang) II receptors in this nucleus. The aim of this study was to evaluate the effects of angiotensin II in hypothalamic paraventricular nucleus (PVN) on renal ischemia-reperfusion inj...
