Exploring the role of mu opioid receptor (OPRM1) and CYP2B6 gene variations for methadone pharmacogenomics. Can these variations be used to advance toxicological interpretation post-mortem?. [PDF]
Methadone is increasingly involved in drug overdose cases and the molecular actions of the drug in vivo are largely unknown requiring elucidation. This study set out to examine the relationship between methadone toxicity and CYP2B6 and mu (μ) opioid ...

Ligand-Specific Regulation of the Endogenous Mu-Opioid Receptor by Chronic Treatment with Mu-Opioid Peptide Agonist [PDF]
, 2013 Since the discovery of the endomorphins (EM), the postulated endogenous peptide agonists of the mu-opioid receptors, several analogues have been synthesized to improve their binding and pharmacological profiles.

Opioids and Their Receptors [PDF]
, 2020 The interest in opioids such as morphine, the prototypical opioid ligand, has been maintained through the years. The identification of endogenous opioids and their receptors (mu, delta, kappa, and nociceptin), molecular cloning, and the elucidation of ...

Opioid mediated activity and expression of mu and delta opioid receptors in isolated human term non-laboring myometrium [PDF]
, 2013 The existence of opioid receptors in mammalian myometrial tissue is now widely accepted. Previously enkephalin degrading enzymes have been shown to be elevated in pregnant rat uterus and a met-enkephalin analogue has been shown to alter spontaneous ...

Inhibition of activity of GABA transporter GAT1 by δ-opioid receptor [PDF]
, 2012 Analgesia is a well-documented effect of acupuncture. A critical role in pain sensation plays the nervous system, including the GABAergic system and opioid receptor (OR) activation.

Clinical opioids differentially induce co-internalization of μ- and δ-opioid receptors
Molecular Pain, 2018 Opioid receptors play an important role in mediating the spinal analgesia. The μ-opioid receptor is the major target of opioid drugs widely used in clinics.
