Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2023 Background The renin‐angiotensin system plays a crucial role in human physiology, and its main hormone, angiotensin, activates 2 G‐protein–coupled receptors, the angiotensin type‐1 and type‐2 receptors, in almost every organ.

Advances in the allostery of angiotensin II type 1 receptor
Cell & Bioscience, 2023 Angiotensin II type 1 receptor (AT1R) is a promising therapeutic target for cardiovascular diseases. Compared with orthosteric ligands, allosteric modulators attract considerable attention for drug development due to their unique advantages of high ...

Upregulation of NADH/NADPH oxidase 4 by angiotensin II induces podocyte apoptosis [PDF]
Kidney Research and Clinical Practice, 2023 Background Angiotensin II induces glomerular and podocyte injury via systemic and local vasoconstrictive or non-hemodynamic effects including oxidative stress. The release of reactive oxygen species (ROS) from podocytes may participate in the development

Angiotensin-[1-12] interacts with angiotensin type I receptors [PDF]
Neuropharmacology, 2014 Angiotensin-(1-12) [Ang-(1-12)], a newer member of angiotensin peptides, is proposed to be converted enzymatically to angiotensin I (Ang I) and to angiotensin II (Ang II); the latter being the bioactive peptide. We studied the Ang-(1-12) and Ang II responses in COS-7 cells or CHO cells transfected with 5 μg AT1R by monitoring [Ca(2+)]i using the Fluo-4.

Angiotensin Type 2 Receptor-Mediated Hypotension in Angiotensin Type-1 Receptor-Blocked Rats [PDF]
Hypertension, 2001 The type-2 (AT 2 ) angiotensin (Ang) II receptor has been characterized as potentially counterregulatory to the actions of Ang II at its type-1 (AT 1 ) receptor. We investigated the effects of Ang II and CGP-42112A (CGP), a selective peptide AT

Does activation of the protective Renin-Angiotensin System have therapeutic potential in COVID-19?
Molecular Medicine, 2020 Infection of lung cells by the corona virus results in a loss of the balance between, on the one hand, angiotensin II-mediated stimulation of the angiotensin II type 1 receptor and, on the other hand, stimulation of the angiotensin II type 2 receptor and/

The angiotensin II type 1 receptor and receptor-associated proteins [PDF]
Cell Research, 2001 The mechanisms of regulation, activation and signal transduction of the angiotensin II (Ang II) type 1 (AT1) receptor have been studied extensively in the decade after its cloning. The AT1 receptor is a major component of the renin-angiotensin system (RAS). It mediates the classical biological actions of Ang II.

Divergent Spatiotemporal Interaction of Angiotensin Receptor Blocking Drugs with Angiotensin Type 1 Receptor [PDF]
Journal of Chemical Information and Modeling, 2017 Crystal structures of the human angiotensin II type 1 receptor (AT1R) complex with the antihypertensive agent ZD7155 (PDB id: 4YAY ) and the blood pressure medication Benicar (PDB id: 4ZUD ) showed that binding poses of both antagonists are similar. This finding implies that clinically used angiotensin receptor blocking (ARB) drugs may interact in a ...

Angiotensin II Type 2 Receptor Antagonizes Angiotensin II Type 1 Receptor–Mediated Cardiomyocyte Autophagy [PDF]
Hypertension, 2009 Autophagy has emerged as an important process in the pathogenesis of cardiovascular diseases, but the proximal triggers for autophagy are unknown. Angiotensin II plays a central role in the pathogenesis of cardiac hypertrophy and heart failure. In this study, we used angiotensin II type 1 (AT 1 ) and type 2 (AT

Angiotensin II Type 1 Receptor Blockers [PDF]
Circulation, 2001 In the 1970s, a series of observations demonstrated that angiotensin II has deleterious effects on the heart and kidney and that patients with high levels of plasma renin activity are at a higher risk of developing stroke or myocardial infarction than those with low plasma renin activity.1 2 Thereafter, the development of pharmacological probes that ...
