Presence and Location of CatSper 1-4, Opioid (μ, δ and κ) and CD44 Receptors in SPERMATOZOA from AOUDAD, IBERIAN IBEX and Mouflon. [PDF]

open access: yesVet Med Sci
Despite the apparent progress in reproductive technologies in wild ruminant species, healthy live births have been limited. Acquiring a sound knowledge of the molecular basis of most functional aspects of spermatozoa will improve the effectiveness of ...

Biased, Bitopic, Opioid–Adrenergic Tethered Compounds May Improve Specificity, Lower Dosage and Enhance Agonist or Antagonist Function with Reduced Risk of Tolerance and Addiction

open access: yesPharmaceuticals, 2022
This paper proposes the design of combination opioid–adrenergic tethered compounds to enhance efficacy and specificity, lower dosage, increase duration of activity, decrease side effects, and reduce risk of developing tolerance and/or addiction ...

Opioid Receptor-Mediated Regulation of Neurotransmission in the Brain

open access: yesFrontiers in Molecular Neuroscience, 2022
Opioids mediate their effects via opioid receptors: mu, delta, and kappa. At the neuronal level, opioid receptors are generally inhibitory, presynaptically reducing neurotransmitter release and postsynaptically hyperpolarizing neurons.

Computational Methods for Understanding the Selectivity and Signal Transduction Mechanism of Aminomethyl Tetrahydronaphthalene to Opioid Receptors

open access: yesMolecules, 2022
Opioid receptors are members of the group of G protein-couple receptors, which have been proven to be effective targets for treating severe pain. The interactions between the opioid receptors and corresponding ligands and the receptor’s activation by ...

Bidirectional Regulation of Opioid and Chemokine Function

open access: yesFrontiers in Immunology, 2020
The opioid family of GPCRs consists of the classical opioid receptors, designated μ-, κ-, and δ-opioid receptors, and the orphanin-FQ receptor, and these proteins are expressed on both neuronal and hematopoietic cells.

Cocaine modulates the expression of opioid receptors and miR-let-7d in zebrafish embryos. [PDF]

open access: yesPLoS ONE, 2012
Prenatal exposure to cocaine, in mammals, has been shown to interfere with the expression of opioid receptors, which can have repercussions in its activity.

Estradiol and Mu opioid-mediated reward: The role of estrogen receptors in opioid use

open access: yesAddiction Neuroscience, 2023
Opioid use and opioid use disorder are characterized by sex and gender differences, and some of these differences may be mediated by differences in the hormonal milieu within and across individuals.

Nucleus Tractus Solitarius Neurons Activated by Hypercapnia and Hypoxia Lack Mu Opioid Receptor Expression

open access: yesFrontiers in Molecular Neuroscience, 2022
Impaired chemoreflex responses are a central feature of opioid-induced respiratory depression, however, the mechanism through which mu opioid receptor agonists lead to diminished chemoreflexes is not fully understood.
