Endothelial Vasodilator Angiotensin Receptors are Changing in Mice with Ageing

Research in Molecular Medicine, 2014
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.

Hypertension regulating angiotensin peptides in the pathobiology of cardiovascular disease

Clinical and Experimental Hypertension, 2018
Renin angiotensin system (RAS) is an endogenous hormone system involved in the control of blood pressure and fluid volume. Dysregulation of RAS has a pathological role in causing cardiovascular diseases through hypertension.

New Approaches to Blockade of the Renin–Angiotensin–Aldosterone System: Chymase as an Important Target to Prevent Organ Damage

Journal of Pharmacological Sciences, 2010
Chymase plays a crucial role in angiotensin II formation in various tissues. Angiotensin II induces gene expression of transforming growth factor (TGF)-β and matrix metalloproteinase (MMP)-9 precursors, and chymase can convert precursors of TGF-β and MMP-

Role of lipoxygenase products in the effects of angiotensin II in the isolated aorta and perfused heart of the rat

Mediators of Inflammation, 1995
The objective of this study was to determine whether arachidonate metabolites are involved in the vasoconstrictive effects of angiotensin II in rats. In the isolated perfused heart, dexamethasone (4 mg/kg) significantly suppressed the maximal decreases ...

Upregulation of angiotensin-(1-7) formation in human podocytes - enzyme activity assay upon fluid flow shear stress.

PLoS ONE
The renin-angiotensin system is known for its role in renal physiology by regulating renal hemodynamics and natriuresis. Overactivation of this system exerts pathological effects in the kidney, primarily mediated by its main effector peptide angiotensin ...

AT1 Receptor Mediated Hypertensive Response to Ang II in the Nucleus Tractus Solitarii of Normotensive Rats Involves NO Dependent Local GABA Release

Frontiers in Pharmacology, 2019
AimIt is well-established that angiotensin II exerts a dampening effect on the baroreflex within the nucleus tractus solitarii (NTS), the principal brainstem site for termination of baroreceptor afferents and which is densely populated with gamma ...

Impaired angiotensin II signaling in septic shock

Annals of Intensive Care
Recent years have seen a resurgence of interest for the renin–angiotensin–aldosterone system in critically ill patients. Emerging data suggest that this vital homeostatic system, which plays a crucial role in maintaining systemic and renal hemodynamics ...

Beneficial Effect of Mas Receptor Deficiency on Vascular Cognitive Impairment in the Presence of Angiotensin II Type 2 Receptor

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2018
BackgroundThe classical renin‐angiotensin system is known as the angiotensin (Ang)‐converting enzyme/Ang II/Ang type 1 receptor axis, which induces various organ damage including cognitive decline.

Angiotensin-(1–7) suppresses pyroptosis in cerebral endothelium to decrease blood–brain barrier permeability and cognitive impairments in sepsis

Journal of International Medical Research
Objective This study aimed to explore the influence of the angiotensin-(1–7)/Mas receptor and angiotensin II/angiotensin II type 1 receptor pathways on pyroptosis during sepsis and their subsequent effects on cognitive function.

Angiotensin II Directly Increases Endothelial Calcium and Nitric Oxide in Kidney and Brain Microvessels In Vivo With Reduced Efficacy in Hypertension

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease
Background The vasoconstrictor effects of angiotensin II via type 1 angiotensin II receptors in vascular smooth muscle cells are well established, but the direct effects of angiotensin II on vascular endothelial cells (VECs) in vivo and the mechanisms ...
