Administered i.p. to mice, the selective kappa receptor agonists U-50488H and spiradoline (U-62066) were more potent on the tail-flick than on the hot-plate analgesic assay. Both were more potent after i.s. rather than i.c. administration, a result consistent with earlier

Increased signaling by G(i)-coupled receptors has been implicated in dilated cardiomyopathy. To investigate the mechanisms, we used transgenic mice that develop dilated cardiomyopathy after conditional expression of a cardiac-targeted G(i)-coupled receptor (Ro1). Activation of G(i) signaling by the Ro1 agonist

The physiological regulation of G protein-coupled receptors, through desensitization and internalization, modulates the length of the receptor signal and may influence the development of tolerance and dependence in response to chronic drug treatment. To explore the importance of receptor regulation

How can we treat patients with reduced morphine doses without loosing the pain killing effect or morphine antinociceptive effects (MAE)? To address this question, we hypothesized that serotonin (5-HT2) receptor antagonism could enhance MAE mediated by kappa-opioid receptors. We pretreated
