Hypothalamic proopiomelanocortin (POMC) neurons release the endogenous opioid beta-endorphin and POMC neuron activity is inhibited by opioids, leading to the proposal that beta-endorphin acts to provide feedback inhibition. However, both intrinsic properties and synaptic inputs contribute to the regulation of

Chronic and/or sustained opioid treatment has been shown to result in development of sensitization of the adenylyl cyclase (AC) system or cAMP overshoot. In this study, we investigated the molecular mechanism responsible for sensitization of the AC system using CHO

Kappa-opioid receptor (KOR) agonists produce dysphoria and psychotomimesis in humans. KORs are enriched in the prefrontal cortex and other brain regions that regulate mood and cognitive function. Dysregulation of the dynorphin/KOR system has been implicated in the pathogenesis of schizophrenia

Opioid signaling in the CNS is critical for controlling cellular excitability, yet the conditions under which endogenous opioid peptides are released and the precise mechanisms by which they affect synaptic transmission remain poorly understood. The opioid peptide dynorphin is present

As reports on G protein-coupled receptor signal transduction mechanisms continue to emphasize potential differences in signaling due to relative receptor levels and cell type specificities, the need to study endogenously expressed receptors in appropriate model systems becomes increasingly important.
