2014-06-01 · The renin-angiotensin-aldosterone system (RAAS) maintains blood pressure through its effects on the kidney to regulate sodium and water balance and on peripheral blood vessels to increase systemic vascular resistance. 7 In 1963, 10 years after the discovery of aldosterone, investigators infused radioactive aldosterone into rats and demonstrated that, in addition to its localization to the kidney, it was also taken up and metabolized by the lungs, heart, and aorta.


14 mars 2020 — Covid och kärl / A2receptorn: Coronavirus disease 2019 may be driven by an overactivation of the renin-angiotensin-aldosterone system – 

The renin angiotensin-aldosterone system (RAAS) is among the most vital physiological programs in our physique. Its important perform is the regulation of blood stress . This system performs a elementary function within the regulation of blood quantity and systemic vascular resistance. All of this influences cardiac output and blood stress.

We begin with the kidney. (1) High-fructose (20%) intake during pregnancy and lactation induces hypertension in consecutive generations of adult offspring; (2) hypertension accompanies renin-angiotensin-aldosterone system activation, fibrosis, inflammation, and oxidative stress in multiple successive generations of offspring; and (3) mRNA expression of the vasodilatory regulating Mas gene and antioxidant-encoding Sod1 Previous studies suggested that exposure to traumatic events during childhood and adulthood and post-traumatic stress disorder (PTSD) are associated with a dysregulation of different neuroendocrine systems. However, the activity of the renin–angiotensin–aldosterone-system (RAAS) in relation to trauma/PTSD has been largely neglected. 2021-04-10 · The renin-angiotensin-aldosterone system (RAAS) is central to the pathogenesis of heart failure.

The renin-angiotensin-aldosterone system (RAAS) plays an important role in cardiovascular homeostasis and its dysfunction relates to negative health consequences. Acute psychosocial stress seems to activate the RAAS in humans, but stress kinetics and interrelations of RAAS parameters compared with a nonstress control group remain inconclusive.
