Brain and Pituitary Angiotensin

SAAVEDRA, JUAN M.·1992·Endocrine Reviews

Abstract

Angiotensin(ANG II) was discovered about 50 yr ago (1, 2), and a complete peripheral system for the formation and metabolism of ANG II was soon characterized. It was named the renin-angiotensin system, based on the rate-limiting enzyme, renin, and the active principle, ANG II (3). In the classical peripheral RAS system, a precursor molecule, angiotensinogen (AOGEN), originates in the liver and is cleaved to the essentially inactive decapeptide angiotensin I (ANG I) by an aspartyl protease, renin, synthesized and released to the circulation mainly by the juxtaglomerular cells of the kidney. ANG I is converted to ANG II, the effector peptide of this system, by the angiotensin-converting enzyme (ACE) (4). Circulating ANG II acts on high affinity ANG II receptors located in the vascular smooth muscle, zona glomerulosa of the adrenal gland, and kidney to produce vasoconstriction, aldosterone release, and sodium retention, respectively. Thus, the peripheral RAS is a hormonal system with important functions in the regulation of blood pressure and fluid homeostasis.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
