Functional Dissociation of μ Opioid Receptor Signaling and Endocytosis Implications for the Biology of Opiate Tolerance and Addiction
Opiate analgesia, tolerance, and addiction are mediated by drug-induced activation of the mu opioid receptor. A fundamental question in addiction biology is why exogenous opiate drugs have a high liability for inducing tolerance and addiction while native ligands do not. Studies indicate that highly addictive opiate drugs such as morphine are deficient in their ability to induce the desensitiza...
متن کاملEvidence of morphine like substance and μ-opioid receptor expression in Toxacara canis (Nematoda: Ascaridae)
Toxocara canis (Nematoda: Ascaridae) is an intestinal nematode parasite of dogs, which can also cause disease in humans. Transmission to humans usually occurs because of direct contact with T. canis eggs present in soil contaminated with the feces of infected dogs. This nematode has extraordinary abilities to survive for many years in different tissues of vertebrates, and deve...
متن کاملReplacement of Serine363 and Serine375 Codons by Alanine in Rat μ-Opioid Receptor cDNA
The aim of this study was to use site directed mutagenesis technique to construct a vector in which serine363 and serine375 residues of the COOH-terminal portion of the μ-opioid receptor (MOR) were substituted by alanine. These constructs are essential in studying G-protein coupled receptor kinase-mediated MOR desensiti-zation. The nested PCR carried out for conversio...
متن کاملLabel-free monitoring of μ-opioid receptor-mediated signaling.
In this study, we used a combination of traditional signaling investigation approaches, bioluminescence resonance energy transfer (BRET) biosensors, and the label-free approach surface plasmon resonance (SPR) spectroscopy to monitor the signaling cascades of the μ-opioid receptor (MOP). In human embryonic kidney cells stably expressing a Flag-tagged version of human MOP, we compared the signals...
متن کاملFunctional Characteristics of the Naked Mole Rat μ-Opioid Receptor
While humans and most animals respond to µ-opioid receptor (MOR) agonists with analgesia and decreased aggression, in the naked mole rat (NMR) opioids induce hyperalgesia and severe aggression. Single nucleotide polymorphisms in the human mu-opioid receptor gene (OPRM1) can underlie altered behavioral responses to opioids. Therefore, we hypothesized that the primary structure of the NMR MOR may...
