mu/delta Cooperativity and opposing kappa-opioid effects in nucleus accumbens-mediated antinociception in the rat
(Blackwell Publishing LtdOxfordInglaterra, 2002)
Activation of μ opioid receptors in the LPBN facilitates sodium intake in rats
(2015)
Important inhibitory mechanisms for the control of water and sodium intake are present in the lateral parabrachial nucleus (LPBN). Opioid receptors are expressed by LPBN neurons and injections of endorphin (nonspecific ...
Pharmacologic evidence for the involvement of central and peripheral opioid receptors in the cardioprotective effects of fentanyl
(Lippincott, Williams & Wilkins, 2020)
Antinociception induced by acute oral administration of sweet substance in young and adult rodents: The role of endogenous opioid peptides chemical mediators and mu(1)-opioid receptors
(PERGAMON-ELSEVIER SCIENCE LTDOXFORD, 2012)
The present work aimed to investigate the effects of acute sucrose treatment on the perception of painful stimuli. Specifically, we sought to determine the involvement of the endogenous opioid peptide-mediated system as ...
Participação dos receptores opióides mu e kappa da substância cinzenta periaquedutal na febre induzida por estresse de contenção
(Universidade Federal de São CarlosUFSCarPrograma Interinstitucional de Pós-Graduação em Ciências Fisiológicas - PIPGCFCâmpus São Carlos, 2016-07-15)
The endogenous opioids are involved in analgesia, thermoregulation and physiological responses to various stressful stimuli such as infection, psychological stress and hypoxia. The mu and kappa receptors in the hypothalamus ...
Racemic salsolinol and its enantiomers act as agonists of the µ-opioid receptor by activating the Gi protein-adenylate cyclase pathway
(Frontiers Media S.A., 2017)
© 2017 Berríos-Cárcamo, Quintanilla, Herrera-Marschitz, Vasiliou, Zapata-Torres and Rivera-Meza. Background: Several studies have shown that the ethanol-derived metabolite salsolinol (SAL) can activate the mesolimbic system, ...
Differential effects of exercise on brain opioid receptor binding and activation in rats
(Wiley-Blackwell, 2015-01-01)
Physical exercise stimulates the release of endogenous opioid peptides supposed to be responsible for changes in mood, anxiety, and performance. Exercise alters sensitivity to these effects that modify the efficacy at the ...
