In various manifestations of cardiovascular disease, blockade of the renin–angiotensin system by angiotensin converting enzyme (ACE) inhibitors has been shown to prevent or delay disease progression effectively and improve prognosis in terms of mortality and morbidity. Angiotensin type 1-receptor (AT1-receptor) blockers, on the other hand, are used for more specific and efficacious blockade of ...
Angiotensin II (Ang II) type 1 (AT1) receptor is known to mediate a variety of physiological actions of Ang II including autophagy. However, the role of AT1 receptor in cardiomyocyte autophagy triggered by mechanical stress still remains elusive. The aim of this study was therefore to examine whether and how AT1 receptor participates in cardiomyocyte autophagy induced by mechanical stresses. A ...
The expression pattern of angiotensin (Ang) II type 2 receptor (AT2-R) in the remodeling process of human left ventricles (LVs) remains poorly defined. We analyzed its expression at protein, mRNA, and cellular levels using autopsy, biopsy, or operation LV samples from patients with failing hearts caused by acute (AMI) or old (OMI) myocardial infarction and idiopathic dilated cardiomyopathy (DCM...
BACKGROUND Accumulating evidence suggests that C-reactive protein (CRP), in addition to predicting vascular disease, may actively facilitate lesion formation by inciting endothelial cell activation. Given the central importance of angiotensin type 1 receptor (AT1-R) in the pathogenesis of atherosclerosis, we examined the effects of CRP on AT1-R expression and kinetics in vascular smooth muscle ...
Radford published an interesting clinical case report of rural patients taking angiotensin II type 1 (AT1) receptor antagonist – commonly also referred to as angiotensin receptor antagonists, AT1 receptor blockers, angiotensin receptor blockers or ARBs – who experienced a sudden loss of consciousness whilst exercising gently in the heat. The findings in this manuscript support, in a clinical se...
Intrarenal Perfusion and Angiotensin II Levels Regulate In Vivo Angiotensin II Type 1 Receptor Imaging in the Kidney To the Editor: In the recent issue of Hypertension, Dr Szabo’s group used novel positron-emission tomographic (PET) [C]KR31173 imaging to study the regulation of intrarenal angiotensin II type 1 (AT1) receptor binding in a swine model of renal artery stenosis in vivo.1 In this st...
background: angiotensin ii (ang ii) has an important role on cerebral microcirculation however, its direct roles in terms of ischemic brain edema need to be clarified. this study evaluated the role of central ang ii by using candesartan, as an at1 receptor blocker, in the brain edema formation and blood-brain barrier (bbb) disruption caused by ischemia/reperfusion (i/r) injuries in rat. methods...
The octapeptide angiotensin II (AngII) exerts a variety of cardiovascular effects through the activation of the AngII type 1 receptor (AT1), a G protein-coupled receptor. The AT1 receptor engages and activates several signaling pathways, including heterotrimeric G proteins Gq and G12, as well as the extracellular signal-regulated kinases (ERK) 1/2 pathway. Additionally, following stimulation, β...
Angiotensin II exerts a mitogenic effect in several in vitro models, but a direct effect on erythroid progenitors has not been documented. Angiotensin-converting enzyme inhibitors and losartan, an angiotensin II type 1 receptor (AT1) antagonist, ameliorate posttransplant erythrocytosis, without altering serum erythropoietin levels. We studied erythroid differentiation and the effect of angioten...
