Sentence Arginine vasopressin interacts with the vasopressin type 1a receptor (V1aR) to initiate physiological effects such as vasoconstriction of blood vessels and glycogenolysis.

MedLine Reference 12724283:0
Sentence The arginine vasopressin (AVP) type 1a receptor (V1a) is well known to mediate vasoconstriction.

Sentence Together, our data suggest that proinflammatory cytokines downregulate V1A receptor expression during sepsis, causing an attenuation of the V1A receptor-mediated vasoconstriction.

Sentence V1a, unlike V2a, is recognized to initiate vasoconstriction upon binding of its ligand vasopressin (anti-diuretic hormone, ADH).

Sentence Oxytocin-evoked renal vasoconstriction was abolished by SR 49059, a selective vasopressin V1A receptor antagonist (10 nM), but not by d(CH2)5[Tyr(Me)2,Thr4,Orn8,Tyr-(NH2)9] vasotocin, an oxytocin receptor antagonist (10 nM).

Sentence A theoretical problem could arise because the circulating AVP, which can no longer bind to the V 2 receptor, is available to bind to the V 1A receptor, which mediates vasoconstriction.

Sentence Another major action of AVP is vasoconstriction, which is mediated by V1aR in vascular smooth muscle cells.

Sentence Activation of the V 1a receptor has been shown to cause peripheral vasoconstriction (Riegger and Leibau, 1982 ; Manning et al., 1993 ; Bichet, 1994 , Burrell et al., 1994 ).

Sentence In the presence of SR 49059 (1 mg/kg i.v.), a vasopressin V1A receptor antagonist that completely abolished the vasopressin-induced renal vasoconstriction, desmopressin again failed to induce vasodilation.

Sentence Therefore, the magnitude of the BP increase seen after in vivo administration of AVP actually represents a summation of V1a receptor-mediated vasoconstriction and V2 receptor/NO-mediated vasodilatation.
