Renin: An enzyme produced by specialised juxtaglomerular cells that catalyses the conversion of angiotensinogen to angiotensin I, initiating a cascade that regulates blood pressure and fluid balance.

The renin-angiotensin-aldosterone system primarily comprises three vital biomolecules: renin, angiotensin II, and aldosterone. These biomolecules exert their effects on the kidney, lungs, vascular ...

The levels of aldosterone, such as catecholamines, renin, and angiotensin II, are associated with a higher mortality rate in heart failure patients.

Kurdi, Amanj, Tanja Mueller, and Natalie Weir. 2022. “An Umbrella Review and Meta‐Analysis of Renin–Angiotensin System Drugs Use and COVID ‐19 Outcomes.” ...

Discontinuing or reducing renin-angiotensin-aldosterone system inhibitor treatment may have negative outcomes for patients with hyperkalemia, but it is a common practice in many clinics, according ...

"Dual blockade of the renin-angiotensin system may offer additional renal and cardiovascular protection in [type 1] diabetic patients with diabetic nephropathy," the authors write, while ...

SARS-CoV-2, the coronavirus that causes Covid-19, enters human cells by binding of its viral spike protein to the membrane-bound form of the monocarboxypeptidase angiotensin-converting enzyme 2 ...

The angiotensin receptor–neprilysin inhibitor sacubitril–valsartan simultaneously blocks the renin–angiotensin system and inhibits the breakdown of several vasoactive peptides. 7 In patients ...

But they do affect the renin-angiotensin system, which regulates blood pressure, the circulatory system, and other functions in the body. ACE2 is a critical component in this system because it ...
