Altered AT1 receptor regulation of ETB receptors in renal proximal tubule cells of spontaneously hypertensive rats.
The renin-angiotensin and endothelin systems regulate blood pressure, in part, by affecting renal tubular sodium transport. In rodents, ETB receptors decrease proximal tubular reabsorption, whereas AT1 receptors produce the opposite effect. We hypothesize that ETB and AT1 receptors interact at the receptor level, and that the interaction is altered in spontaneously hypertensive rats (SHRs). In ...
متن کاملBlood Pressure Responses of Conscious Normotensive and Spontaneously Hypertensive Rats
In conscious spontaneously hypertensive rats, intracerebroTentricular injection of captopril (2 rag/kg) resulted in a rapid hypotenshe response that lasted several hours. The same dose given by Intracerebroventricular injection had no significant effect on blood pressure (BP) of normotensive Wistar-Kyoto (WK) rats over 7 hours. There was no significant change in BP of conscious spontaneously hy...
متن کاملAcupuncture Attenuates Renal Sympathetic Activity and Blood Pressure via Beta-Adrenergic Receptors in Spontaneously Hypertensive Rats
The sympathetic nervous system, via epinephrine and norepinephrine, regulates β-adrenergic receptor (β-AR) expression, and renal sympathetic activation causes sustained increases in blood pressure by enhanced renin release. In this study, we aim to investigate the effect and underlying mechanism of acupuncture at Taichong (LR3) on renal sympathetic activity in spontaneously hypertensive rats. U...
متن کاملRenal function of conscious spontaneously hypertensive rats.
Renal clearance studies were performed in conscious 13-week-old spontaneously hypertensive rats (SHR) and normotensive Wistar-Kyoto rats (WKY) before and during volume expansion by intravenous infusion of isotonic saline. Mean arterial pressure and filtration fraction were greater in SHR, whereas fractional and absolute excretion of sodium and water, glomerular filtration rate, and renal plasma...
متن کاملVentrolateral medulla AT1 receptors support blood pressure in hypertensive rats.
Angiotensin within the central nervous system appears to be important for the maintenance of hypertension in spontaneously hypertensive rats. This study addresses the hypothesis that blockade of AT1 receptors in the rostral ventrolateral medulla would decrease blood pressure in spontaneously hypertensive rats and that this tonically active AT1-mediated input to the rostral ventrolateral medulla...
