GRKs as Key Modulators of Opioid Receptor Function
Understanding the link between agonist-induced phosphorylation of the mu-opioid receptor (MOR) and the associated physiological effects is critical for the development of novel analgesic drugs and is particularly important for understanding the ...

Molecular Aspects of Opioid Receptors and Opioid Receptor Painkillers
The unpleasant sensation of pain is experienced by all human beings at a given point in life. When pain gets severe and/or chronic it requires medical treatment. For over a thousand years, opioid agonists have been employed therapeutically to treat pain, with the first reports of such use involving the alkaloid morphine dated to the second century B.C.(

Caenorhabditis elegans as a model system to identify therapeutics for alcohol use disorders [PDF]
Alcohol use disorders (AUDs) cause serious problems in society and few effective treatments are available. Caenorhabditis elegans (C. elegans) is an excellent invertebrate model to study the neurobiological basis of human behavior with a conserved, fully

Measuring ligand efficacy at the mu-opioid receptor using a conformational biosensor. [PDF]
The intrinsic efficacy of orthosteric ligands acting at G-protein-coupled receptors (GPCRs) reflects their ability to stabilize active receptor states (R*) and is a major determinant of their physiological effects.

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

The novel mu-opioid antagonist, GSK1521498, reduces ethanol consumption in C57BL/6J mice. [PDF]
RATIONALE Using the drinking-in-the-dark (DID) model, we compared the effects of a novel mu-opioid receptor antagonist, GSK1521498, with naltrexone, a licensed treatment of alcohol dependence, on ethanol consumption in mice.
