Effect of vasoactive intestinal polypeptide on the cyclic adenosine monophosphate generating system in rat kidney
Regulatory Peptides
|May 1, 1987
Abstract:
The effect of in vitro addition of vasoactive intestinal polypeptide (VIP) on the 3'-5'-cyclic adenosine monophosphate (cAMP) generating system in rat kidney glomeruli and cortical tubules was studied. VIP did not stimulate cAMP accumulation in glomeruli; but VIP did stimulate, specifically and in a dose-dependent manner, cAMP concentrations in tubular membranes with the addition of GTP. These results are consistent with the existence of a functionally active VIP receptor coupled to adenylate cyclase in rat kidney cortical tubules.
