Possible presence of V1 vasopressin receptor in toad urinary bladder.
The V1 vasopressin receptor antagonist, d(CH2)5Try(Me)AVP, enhanced the vasopressin-stimulated osmotic water flow in the toad bladder and inhibited the vasopressin-induced prostaglandin E2 production at 1 x 10(-9) M. It is well known that prostaglandin E2 inhibits the vasopressin-induced water flow in the toad bladder. These results indicate that the V1 vasopressin receptor is possibly present in the toad urinary bladder.
