The Role of Renin-Angiotensin-Aldosterone System in the Heart and Lung: Focus on COVID-19.

Front Pharmacol 2021 20;12:667254. Epub 2021 Apr 20.

Campania Regional Centre for Pharmacovigilance and Pharmacoepidemiology, Naples, Italy.

The renin-angiotensin-aldosterone system (RAAS) firstly considered as a cardiovascular circulating hormonal system, it is now accepted as a local tissue system that works synergistically or independently with the circulating one. Evidence states that tissue RAAS locally generates mediators with regulatory homeostatic functions, thus contributing, at some extent, to organ dysfunction or disease. Specifically, RAAS can be divided into the traditional RAAS pathway (or classic RAAS) mediated by angiotensin II (AII), and the non-classic RAAS pathway mediated by angiotensin 1-7. Read More
