Opioid peptides, opioid receptors and mechanism of down regulation.
Biogenesis of various endogenous opioid peptides, anatomical distribution and the characteristics of multiple receptors with which they interact provides an opportunity for understanding the role of opioid systems and mechanism of opioid tolerance. Cellular and anatomical distribution of opioid receptor and their function is important for identification of neuronal systems and local network inv...
متن کاملStructural and functional interactions between six-transmembrane μ-opioid receptors and β2-adrenoreceptors modulate opioid signaling
The primary molecular target for clinically used opioids is the μ-opioid receptor (MOR). Besides the major seven-transmembrane (7TM) receptors, the MOR gene codes for alternatively spliced six-transmembrane (6TM) isoforms, the biological and clinical significance of which remains unclear. Here, we show that the otherwise exclusively intracellular localized 6TM-MOR translocates to the plasma mem...
متن کاملP80: Investigation of Interactions between Glucocorticoid and Opioid Receptors on Anxiety Modulation in Mice
Recent studies have shown that glucocorticoids may have modulatory effect on anxiety reactions. This effect may occur with opioid system interference. According to that, the purpose of this research is to assess the effect of dexamethasone as glucocorticoid agonist and its interaction with opioidergic system on the anxiety modulatory effect in plus maze model in mice. Male white mice with mediu...
متن کاملOpioid Receptors of the Central Amygdala and Morphine-Induced Antinociception
The amygdala is a forebrain region, which is known as a modulator of pain sensation. The amygdala, particularly the central nucleus, has high concentrations of enkephalins relative to dynorphins and has high concentrations of opioid receptors. We here studied the role of central nuclei of amygdala in morphine antinociception. Methods: In this study, we used 130 male Wistar rats (200- 250g). Bil...
متن کاملFunctional interaction between opioid and cannabinoid receptors in drug self-administration.
The present study was designed to explore the relationship between the cannabinoid and opioid receptors in animal models of opioid-induced reinforcement. The acute administration of SR141716A, a selective central cannabinoid CB1 receptor antagonist, blocked heroin self-administration in rats, as well as morphine-induced place preference and morphine self-administration in mice. Morphine-depende...
