1985-01-08 · A kappa-selective opioidergic pathway is involved in the reversal of a behavioural effect of adrenalectomy. Jefferys D, Boublik J, Funder JW. We have shown previously that adrenalectomized rats are immobile for only approximately 30% of a 5 min retest period, 24 h after an initial 15 min swimming exposure, compared with approximately 70% immobility for intact animals.

The opioid receptor was antagonized by a 2 mg/kg intraperitoneal naloxone injection at time point 15 and 1 16 Nov 2018 We investigated this issue using a within subject, pharmacological challenge design with the opioid receptor antagonist naloxone and fMRI. Our Multisensory competition is modulated by sensory pathway interactions with fronto-sensorimotor and default-mode network regions. J Neurosci 35(24):9064– 77. dose related antinociception in models of chemical and thermal nociception through mechanisms that involve an interaction with opioidergic pathway. An opioidergic agent (or drug) is a chemical which functions to directly modulate the opioid neuropeptide systems in the body or brain.
Abstract. Two experiments were conducted to determine whether dopaminergic or opioidergic pathways are modulated by thyroid gland secretions for seasonal suppre Abstract The endogenous opioid peptides (EOP) comprise a family of neurotransmitters which profoundly influence reproduction. A major component of their effects is modulation of gonadotrophin secretion via interactions with other neural pathways or systems impinging upon luteinising hormone releasing hormone (LHRH) neurones. Limited evidence also exists for direct effects of EOP at the Opioidergic system and N-methyl D-aspartate receptor (NMDA-R) hypofunction: Translational implications for the pathophysiology of psychosis and drug addiction - Volume 26 Issue S2.

Propofol inhibits intestinal peristalsis by increasing the PPT, but is less potent and effective compared to barbiturates or clonidine since it did not abolish peristaltic activity. The inhibitory effect of propofol seems not to be mediated through binding to GABA A receptors, but seems to involve enteric opioidergic pathways.

Here, we show that the opioidergic analgesia pathway is bifurcated in structure and function at the PAG. A knockout as well as a PAG-specific knockdown of phospholipase C β4
The Ontario Journal Opioidergic mechanisms in the human brain. Cerebral Cortex Participation of central opioidergic pathways has been suggested based on work in rats showing that running can alter opiate cerebrospinal fluid levels Opioidergic modulation of striatal circuits, implications in parkinson's disease into direct and indirect output pathways, striosomes and matrix compartments.
Conclusions and outlook. As described above, there is substantial evidence supporting a role for endogenous cholinergic modulation of pain as well as a basis for the therapeutic usage of cholinomimetics in pain relief.

However, whether this pathway is activated in visceral pain or if it involves subdiaphragmatic vagal afferents is unclear. The aim of the present study was to determine whether subdiaphragmatic vagal afferents mediate antinociception in response to a visceral stimulus and whether this involves an opioid pathway. circuit is bifurcated into two distinct pathways, each with an opposing effect on opioid analgesia at the PAG level: sup-pressing through the PAG-LC pathway while enhancing through the PAG-rostral ventromedial medulla pathway.
CONCLUSIONS: These results suggest that gabapentin produce antinociception partly via the activation nitridergic pathways and opioid system.

Conclusions: Exercise can simultaneously modulate the rsFC of the descending opioidergic pathway and reward/motivation system and blood inflammation markers. Elucidating the shared and unique mechanisms of different exercise modalities may facilitate the development of exercise-based interventions for chronic pain. This pathway probably involves opioid mechanisms. However, whether this pathway is activated in visceral pain or if it involves subdiaphragmatic vagal afferents is unclear. The aim of the present study was to determine whether subdiaphragmatic vagal afferents mediate antinociception in response to a visceral stimulus and whether this involves an opioid pathway. circuit is bifurcated into two distinct pathways, each with an opposing effect on opioid analgesia at the PAG level: sup-pressing through the PAG-LC pathway while enhancing through the PAG-rostral ventromedial medulla pathway. Thus, the yin-and-yang model is proposed for the opioidergic descend-ing analgesia.
