متن کاملRole of renal prostaglandins in the control of renin release.
CONTROL of renin release is multifactorial and complex. Stimuli for renin release act through three groups of mechanisms which include: two intrarenal receptors, the renal vascular baroreceptor in the afferent arterioles and the macula densa in the distal nephron; the renal sympathetic nerves and a renal /9-adrenergic receptor; and a group of humoral agents (Davis and Freeman, 1976; Keeton and ...
متن کاملRenal Baroreceptor Control of Acute Renin Release in Normotensive, Nephrogenic and Neurogenic Hypertensive Dogs.
• Normal kidneys have recently been shown to possess a pressure sensing mechanism that responds to small reductions in mean renal arterial perfusion pressure by increasing the rate of renin secretion.' This baroreceptor function of the kidney is operative within physiological ranges of pressure and thus may be a homeostatic mechanism participating in control of normal arterial pressure. The ter...
متن کاملBiomechanical coupling in renin-releasing cells.
The renin-angiotensin system is a major regulatory system controlling extracellular fluid volume and blood pressure. The rate-limiting enzyme in this hormonal cascade is renin, which is synthesized and secreted into the circulation by renal juxtaglomerular (JG) cells. The renal baroreceptor is a key physiologic regulator of renin secretion, whereby a change in renal perfusion pressure is sensed...
متن کاملThe prostaglandin system. A role in canine baroreceptor control of renin release.
We used the nonfiltering kidney model with contralateral nephrectomy to investigate the site where prostaglandins influence renin release. Adrenergic influences on renin release were excluded by renal denervation, bilateral adrenalectomy, and a continuous propranolol infusion. In this model, reduction of renal perfusion pressure by 50% increased renal venous renin activity from 3.10 ± 0.66 to 1...
