1 In vivo, epinephrine and the vasopressin analog DDAVP increase vWf plasma levels, although they are thought not to induce vWf release from endothelial cells in vitro. Epinephrine von Willebrand factor Homo sapiens
2 Epinephrine (together with IBMX) caused a small, dose-dependent increase in vWf release, maximal at 10(-6) M (+50%), and also potentiated the response to thrombin. Epinephrine von Willebrand factor Homo sapiens
3 We found a close correlation between cellular cAMP content and vWf release after stimulation with epinephrine and forskolin. Epinephrine von Willebrand factor Homo sapiens
4 These results demonstrate that cAMP-dependent signaling events are involved in the control of exocytosis from endothelial cells (an effect not mediated by an increase in [Ca2+]i) and provide an explanation for epinephrine-induced vWf release. Epinephrine von Willebrand factor Homo sapiens
