Key result
Stimulation of renal mechanoreceptors and chemoreceptors failed to elicit a renorenal reflex response in spontaneously hypertensive rats compared to normotensive rats, indicating impaired reflexes.
Why the study?
Are renorenal reflexes impaired in spontaneously hypertensive rats compared to normotensive rats?
Are renorenal reflexes impaired in spontaneously hypertensive rats compared to normotensive rats?
Renorenal reflexes are impaired in spontaneously hypertensive rats, likely due to a peripheral defect at the level of the renal sensory receptors.

Impaired renorenal reflexes in hypertensive rat models are hypothesis-generating; leaves open peripheral sensory defects in human hypertension pathogenesis.
Kopp et al. (1987) studied Hypertension. Stimulation of renal mechanoreceptors and chemoreceptors vs. Normotensive Wistar-Kyoto rats (WKY) was evaluated on Renorenal reflex response (ipsilateral afferent and contralateral efferent renal nerve activity, contralateral diuresis and natriuresis). Stimulation of renal mechanoreceptors and chemoreceptors failed to elicit a renorenal reflex response in spontaneously hypertensive rats compared to normotensive rats, indicating impaired reflexes.
