چکیده

Ang II is the major effector of the Renin–Angiotensin–Aldosterone System (RAAS). This system consists mainly of a 2-step enzymatic cascade catalyzed by renin and Angiotensin-Converting Enzyme (ACE), generating Ang II [1], the effect of Ang II is mediated by Ang II receptors. Two isoforms of Ang II receptor have been identified: type 1 receptor (AT1R) and type 2 receptor (AT2R). In general, it is accepted that cardiovascular effects of Ang II such as vasoconstriction, regulation of fluid and drinking behavior are ascribed to AT1R. Besides, AT1R is involved in the progression of cardiovascular diseases including hypertension, atherosclerosis, cardiac hypertrophy and heart failure [2,3].

Role of Angiotensin II in Reactive Oxygen Species Production and Modulatory Role of Nitric Oxide (NO) in Vessel Responses to AngII in Acute Joint Inflammation in the Rabbit

Introduction: It has been approved that in most tissues NO production increases during acute inflammation and Angiotensin II has a role in production of reactive oxygen species (ROS). As regulation of joint blood flow (JBF) is important in this situation, this study was performed to investigate the interaction of local Ang II and ROS production and the modulatory role of NO on regulation of JBF...

The Brain Renin-Angiotensin System and Mitochondrial Function: Influence on Blood Pressure and Baroreflex in Transgenic Rat Strains

Mitochondrial dysfunction is implicated in many cardiovascular diseases, including hypertension, and may be associated with an overactive renin-angiotensin system (RAS). Angiotensin (Ang) II, a potent vasoconstrictor hormone of the RAS, also impairs baroreflex and mitochondrial function. Most deleterious cardiovascular actions of Ang II are thought to be mediated by NADPH-oxidase- (NOX-) derive...

Inflammation and vascular hypertrophy induced by angiotensin II: role of NADPH oxidase-derived reactive oxygen species independently of blood pressure elevation?

Evidence from the last few years has suggested that increased oxidative stress plays a pathophysiological role in cardiovascular disease, including atherosclerosis, hypertension, and heart failure.1,2 At the same time, emerging data have implicated inflammation as a process involved in the initiation and progression of atherosclerosis, but it is also present in hypertension, diabetes mellitus, ...

Integrative Physiology Transcriptional Upregulation of Brain-Derived Neurotrophic Factor in Rostral Ventrolateral Medulla by Angiotensin II Significance in Superoxide Homeostasis and Neural Regulation of Arterial Pressure

Rationale: Oxidative stress in rostral ventrolateral medulla (RVLM), where sympathetic premotor neurons for the maintenance of neurogenic vasomotor tone are located, contributes to neural mechanisms of hypertension. Emerging evidence suggests that brain-derived neurotrophic factor (BDNF) manifests " nontrophic " actions. Objective: We assessed the hypothesis that BDNF plays an active role in ox...

TMEM16A Contributes to Endothelial Dysfunction by Facilitating Nox2 NADPH Oxidase-Derived Reactive Oxygen Species Generation in Hypertension.

Ca2+-activated Cl- channels play a crucial role in various physiological processes. However, the role of TMEM16A in vascular endothelial dysfunction during hypertension is unclear. In this study, we investigated the specific involvement of TMEM16A in regulating endothelial function and blood pressure and the underlying mechanism. Reverse transcription-polymerase chain reaction, Western blotting...
