Abstract

The renal pressure-natriuresis mechanism is the dominant controller of body fluid balance and long-term arterial pressure. In recent years, it has become clear that the balance of reactive oxygen and nitrogen species within the renal medullary region is a key determinant of the set point of the renal pressure-natriuresis curve. The development of renal medullary oxidative stress causes dysfunction of the pressure-natriuresis mechanism and contributes to the development of hypertension in numerous disease models. The purpose of this review is to point out the known mechanisms within the renal medulla through which reactive oxygen and nitrogen species modulate the pressure-natriuresis response and to update the reader on recent advances in this field.

Using in vivo microdialysis techniques, Jin et al. demonstrate that increasing renal perfusion pressure stimulates renal medullary NO and H 2 O 2 . Importantly, NO stimulation was not affected by renal decapsulation and inhibition of the renal natriuretic response, suggesting that the increased production of NO may be a primary event in the renal pressure-natriuresis cascade.

Hypertension 2009, 54(6):1278–1283. Lieb et al. demonstrate that cyclic guanosine 3′5′-monophosphate is produced in response to increases in RIHP and also acts to increase RIHP through an unknown mechanism. By activating a positive feedback loop, cyclic guanosine 3′5′-monophosphate may allow the kidney to rapidly reduce sodium and water reabsorption when renal perfusion pressure is elevated.
