Behavioral meaningful opioidergic stimulation activates kappa receptor gene expression
(Associação Brasileira de Divulgação Científica, 2012)
The periaqueductal gray (PAG) has been reported to be a location for opioid regulation of pain and a potential site for behavioral selection in females. Opioid-mediated behavioral and physiological responses differ according ...
Blockade of central kappa-opioid receptors inhibits the antidipsogenic effect of interleukin-1β
(Brasil, 2009)
The objective of the present study was to investigate the role of brain kappa-opioid receptors (KOR) in the antidipsogenic effect promoted by third ventricle injections of interleukin-1β (IL-1β). Wistar male rats were ...
Peripheral effect of a kappa opioid receptor antagonist on nociception evoked by formalin injected in TMJ of pregnant rats
(Pergamon-elsevier Science LtdOxfordInglaterra, 2005)
Plasticity of Opioid Receptors in the Female Periaqueductal Gray: Multiparity-Induced Increase in the Activity of Genes Encoding for Mu and Kappa Receptors and a Post-Translational Decrease in Delta Receptor Expression
(HUMANA PRESS INC, 2011)
The periaqueductal gray (PAG) has been reported as a potential site for opioid regulation of behavioral selection. Opioid-mediated behavioral and physiological responses differ between nulliparous and multiparous females. ...
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 ...
Crosstalk Between Kappa Opioid and Dopamine Systems in Compulsive Behaviors
(Frontiers Media, 2020)
The strength of goal-oriented behaviors is regulated by midbrain dopamine neurons. Dysfunctions of dopaminergic circuits are observed in drug addiction and obsessive-compulsive disorder. Compulsive behavior is a feature ...
