Calcium 88-95 arginine vasopressin Rattus norvegicus 4-15 1838582-2 1991 We determined the effect of arginine vasopressin (AVP) on the intracellular free calcium concentration [Ca2+]i in endothelial cells of isolated hippocampal microvessels of rats, using the fura-2 fluorescence technique. Calcium 81-88 arginine vasopressin Rattus norvegicus 37-48 1838582-3 1991 AVP administration caused a rapid and transient rise of cytosolic free calcium which was absent after extracellular calcium was removed, and could be blocked with the vasopressin V1 receptor antagonist, d(CH2)5 Tyr(Me)AVP. Calcium 71-78 arginine vasopressin Rattus norvegicus 167-178 1838582-3 1991 AVP administration caused a rapid and transient rise of cytosolic free calcium which was absent after extracellular calcium was removed, and could be blocked with the vasopressin V1 receptor antagonist, d(CH2)5 Tyr(Me)AVP. Calcium 116-123 arginine vasopressin Rattus norvegicus 167-178 1838582-5 1991 Our results, therefore, demonstrate the presence of a calcium-signalling, i.e. V1 vasopressin receptor at the blood-brain barrier in the hippocampus of the rat.
