Secreting renin

WebRenal pericytes have key roles in homeostasis; for example, they can regulate blood pressure either directly by their contraction or indirectly by the secretion of renin by certain subpopulations. 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.
