Obesity is associated with decreased μ-opioid but unaltered dopamine D2 receptor availability in the brain.
Neurochemical pathways involved in pathological overeating and obesity are poorly understood. Although previous studies have shown increased μ-opioid receptor (MOR) and decreased dopamine D2 receptor (D2R) availability in addictive disorders, the role that these systems play in human obesity still remains unclear. We studied 13 morbidly obese women [mean body mass index (BMI), 42 kg/m(2)] and 1...
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 کاملLigand bias at the μ-opioid receptor.
Ligand bias refers to the ability of a drug at a receptor to activate selectively particular cell signalling pathways over others, in a way that cannot be explained by traditional models of receptor theory. For a physiologically and therapeutically important GPCR (G-protein-coupled receptor) such as the MOPr (μ-opioid receptor), the role of ligand bias is currently being explored, not only in o...
متن کاملReduced basal ganglia μ-opioid receptor availability in trigeminal neuropathic pain: A pilot study
BACKGROUND Although neuroimaging techniques have provided insights into the function of brain regions involved in Trigeminal Neuropathic Pain (TNP) in humans, there is little understanding of the molecular mechanisms affected during the course of this disorder. Understanding these processes is crucial to determine the systems involved in the development and persistence of TNP. FINDINGS In thi...
