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

The selective kappa-opioid receptor agonist spiradoline mesylate (U62,066E), an arylacetamide, was synthesized with the intention of creating an analgesic that, while still retaining its analgesic properties, would be devoid of the, mainly mu receptor mediated, side effects such as physical

Both enkephalin and dynorphin containing fibers are in close proximity to neurons in the nucleus ambiguus, including cardiac vagal neurons. Microinjection of Delta and kappa agonists into the nucleus ambiguus have been shown to evoke decreases in heart rate. Yet

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

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
