WebProrenin/renin secretion is under the control of Ang II through a negative feedback loop. Thus, the magnitude of compensatory prorenin/renin secretion appears dependent on the degree of RAAS activation through the Ang I–Ang II arm.

WebWhat is abnormal renin secretion? A hypotensive response, or lack of it, to angiotensin-converting enzyme inhibitor is similarly informative. Because the normal kidney exposed to high arterial pressure and normal salt intake will reduce its renin secretion to near zero, any renin secretion in a hypertensive setting can be considered abnormal.

Web16 Apr 2024 · In vitro studies have suggested the expression of Ang II-AT1 receptors by juxtaglomerular cells. 33,34 In addition, Ang II has been repeatedly shown to rapidly inhibit renin secretion from isolated perfused kidneys 35 – 37 or kidney slices. 6,38 The combination of these in vivo and in vitro findings has led to the concept that renin … WebIn primary hyperaldosteronism, aldosterone secretion is inappropriately high for the level of body salt and blood volume regardless of the renin level in the blood (which is usually suppressed). Secondary hyperaldosteronism occurs when the kidney produces too much renin. This is often seen in patients with chronic low blood volume such as in ...

Renin's primary function is therefore to eventually cause an increase in blood pressure, leading to restoration of perfusion pressure in the kidneys. Renin is secreted from juxtaglomerular kidney cells, which sense changes in renal perfusion pressure, via stretch receptors in the vascular walls.
