Rubsicolins are naturally occurring G-protein-biased delta opioid receptor peptides
bioRxiv, 2018 The impact that β-arrestin proteins have on G-protein-coupled receptor trafficking, signaling and physiological behavior has gained much appreciation over the past decade.

Stress-Dependent Impairment Of Passive-Avoidance Memory By Propranolol Or Naloxone [PDF]
, 2011 Previous work has shown that the effect of opioid-receptor blockade on memory modulation is critically dependent upon the intensity of stress. The current study determined the effect of adrenergic-receptor blockade on memory modulation under varied ...

The unsolved case of “bone-impairing analgesics”. The endocrine effects of opioids on bone metabolism [PDF]
, 2015 The current literature describes the possible risks for bone fracture in chronic analgesics users. There are three main hypotheses that could explain the increased risk of fracture associated with central analgesics, such as opioids: 1) the increased ...

Molecular Perspectives for mu/delta Opioid Receptor Heteromers as Distinct, Functional Receptors
Cells, 2014 Opioid receptors are the sites of action for morphine and the other opioid drugs. Abundant evidence now demonstrates that different opioid receptor types can physically associate to form heteromers.

High-affinity naloxone binding to filamin a prevents mu opioid receptor-Gs coupling underlying opioid tolerance and dependence. [PDF]
PLoS ONE, 2008 Ultra-low-dose opioid antagonists enhance opioid analgesia and reduce analgesic tolerance and dependence by preventing a G protein coupling switch (Gi/o to Gs) by the mu opioid receptor (MOR), although the binding site of such ultra-low-dose opioid ...

The novel mu-opioid antagonist, GSK1521498, reduces ethanol consumption in C57BL/6J mice. [PDF]
, 2015 RATIONALE Using the drinking-in-the-dark (DID) model, we compared the effects of a novel mu-opioid receptor antagonist, GSK1521498, with naltrexone, a licensed treatment of alcohol dependence, on ethanol consumption in mice.

Pharmacological Profiles of Oligomerized μ-Opioid Receptors
Cells, 2013 Opioids are widely prescribed pain relievers with multiple side effects and potential complications. They produce analgesia via G-protein-protein coupled receptors: μ-, δ-, κ-opioid and opioid receptor-like 1 receptors.

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.
