Angiotensin Type 1 Receptor Blockers in Heart Failure.

Current Drug Targets, 2020
Homeostasis in the cardiovascular system is maintained by physiological functions of the Renin Angiotensin Aldosterone System (RAAS). In pathophysiological conditions, over activation of RAAS leads to an increase in the concentration of Angiotensin II ...

Angiotensin II Type 1 Receptor Autoantibodies in Postural Tachycardia Syndrome

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundBoth the adrenergic and renin‐angiotensin systems contribute to orthostatic circulatory homeostasis, which is impaired in postural orthostatic tachycardia syndrome (POTS).

Renal Angiotensin Type 2 Receptors Mediate Natriuresis Via Angiotensin III in the Angiotensin II Type 1 Receptor–Blocked Rat [PDF]

Hypertension, 2006
Whereas angiotensin (Ang) II is the major effector peptide of the renin–angiotensin system, its metabolite, des-aspartyl1-Ang II (Ang III), may also have biologic activity. We investigated the effects of renal interstitial (RI) administration of candesartan (CAND), a specific Ang II type 1 receptor (AT1) blocker, with and without coinfusion of PD ...

Decoding Angiotensin Receptors: TOMAHAQ‐Based Detection and Quantification of Angiotensin Type‐1 and Type‐2 Receptors

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.

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

Angiotensin-(1–1) Suppresses Hepatocellular Carcinoma Growth and Angiogenesis via Complex Interactions of Angiotensin II Type 1 Receptor, Angiotensin II Type 2 Receptor and Mas Receptor

Molecular Medicine, 2015
We recently confirmed that angiotensin II (Ang II) type 1 receptor (AT1R) was overexpressed in hepatocellular carcinoma tissue using a murine hepatoma model. Angiotensin(Ang)-(1-7) has been found beneficial in ameliorating lung cancer and prostate cancer.

Angiotensin type 2 receptor actions contribute to angiotensin type 1 receptor blocker effects on kidney fibrosis.

American Journal of Physiology-Renal Physiology, 2010
Angiotensin type 1 (AT1) receptor blocker (ARB) ameliorates progression of chronic kidney disease. Whether this protection is due solely to blockade of AT1, or whether diversion of angiotensin II from the AT1to the available AT2receptor, thus potentially enhancing AT2receptor effects, is not known.

Telmisartan reduces systemic inflammation and alters the renin-angiotensin system in mild COVID-19 [PDF]

Scientific Reports
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes COVID-19, a respiratory viral infection that disrupts renin angiotensin system (RAS) peptide metabolism by downregulating angiotensin converting enzyme-II (ACE2), leading to accumulation

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.
