Increases in renal sympathetic nerve activity regulate the functions of the nephron, the vasculature, and the renin-containing juxtaglomerular granular cells. Because increased activity of the renin-angiotensin system can also influence nephron and vascular function, it is important to understand the interactions between the renal sympathetic nerves and the renin-angiotensin system in the contr...

Knowledge of the structure, function and distribution of the components of the renin-angiotensin-aldosterone system (RAS) and the integrated physiological role of this hormonal system is rapidly increasing, although many questions remain unanswered. The primary structure and localisation of RAS such as renin, prorenin, angiotensinogen, angiotensin-converting enzyme (ACE) and the angiotensins ha...

The renin-angiotensin system plays a central role in the pathogenesis of cardiovascular disease. At the molecular and cellular levels, angiotensin II, the main effector peptide of the system, stimulates key components of atherosclerosis. Trials in animals and humans indicate that blocking renin-angiotensin system pathways decreases atherosclerotic plaque progression and ischemic events. This re...

Dietary salt intake is a major determinant of the activation state of renin-angiotensin-aldosterone system. Given the important role of the renin-angiotensin-aldosterone system in plaque accumulation, we investigated its role in the development of atherogenesis associated with sodium intake in apolipoprotein E knockout mice. Six-weeks of a low-salt diet (containing 0.03% sodium) resulted in a 4...

Angiotensinogen, angiotensin-converting enzyme, and renin constitute the components of the renin-angiotensin system. The mammalian renal proximal tubule contains angiotensinogen, angiotensin-converting enzyme, and angiotensin receptors. Previous immunohistochemical studies describing the presence of renin in the proximal tubule could not distinguish synthesized renin from renin trapped from the...

The “classical” renin-angiotensin system is known to maintain blood pressure and body fluids. However, increased understanding of its individual components and their structures and regulatory mechanisms, and the convergence and crosstalk with related pathways has resulted in the appreciation of a much more complex system. Research has shown that the renin-angiotensin system is implicated in a w...

The renin-angiotensin system has long been recognized as an important regulator of systemic blood pressure and renal electrolyte homeostasis, and local renin-angiotensin systems have also been implicated in pathological changes of organ structure and function by modulation of gene expression, growth, fibrosis, and inflammatory response. Recently, substantial data have been accumulated in suppor...

Literature data on the role of renin-angiotensin-aldosterone system in pathogenesis arterial hypertension and angiotensin-converting enzyme inhibitors treatment have been given.The is central element controlling body's water-salt balance blood pressure. The main effector link renin-angiotensin angiotensin II, which causes vasospasm, activates heart contraction, inhibits production bradykinin, p...

In recent years, the renin-angiotensin-aldosterone system has been shown to be crucial not only in blood pressure haemostasis but also in the evolution of atherosclerosis, which ultimately determines morbidity and mortality. The angiotensin-converting enzyme inhibitors and, recently, the angiotensin receptor blockers (with their low adverse-effect profile) have added a new dimension to the drug...
