Oligomerization of opioid receptors

Methods, 2002
Opioid receptors belong to the family of G-protein-coupled receptors characterized by their seven transmembrane domains. The activation of these receptors by agonists such as morphine and endogenous opioid peptides leads to the activation of inhibitory G-proteins followed by a decrease in the levels of intracellular cAMP.

Biased Agonism of Endogenous Opioid Peptides at the μ-Opioid Receptor

Molecular Pharmacology, 2015
Biased agonism is having a major impact on modern drug discovery, and describes the ability of distinct G protein–coupled receptor (GPCR) ligands to activate different cell signaling pathways, and to result in different physiologic outcomes.

Opioid Receptors and their Ligands

Current Topics in Medicinal Chemistry, 2004
This review gives a historical perspective, summarizing approximately 25 years of research on opioids. The "typical" opioid peptides produced in the brain, "atypical" opioids encrypted in milk protein or hemoglobin sequences, and extremely potent and selective opioids of amphibian origin are described.

Opioid receptors and opioid pharmacodynamics

2005
Abstract Opioids have a long and rich pharmacology. They are widely used throughout medicine and have been invaluable. However, they come with problems, including side effects such as constipation, respiratory depression and sedation, as well as the potential of abuse.

Opioid peptide receptor studies. 4. Antisense oligodeoxynucleotide to the delta opioid receptor delineates opioid receptor subtypes

Regulatory Peptides, 1995
Prior work in our laboratory has identified putative subtypes of delta (delta cx-1, delta cx-2, delta ncx-1, delta ncx-2) and kappa 2 (kappa 2a and kappa 2b) receptors. Previous studies showed that chronic (three day) i.c.v. administration of antisense oligodeoxynucleotide to the cloned delta opioid receptor selectively decreased [3H][D-Ala2,D-Leu5 ...

Opioid Receptor Regulation

NeuroMolecular Medicine, 2004
Opioid receptors are regulated by multiple mechanisms, which are believed to contribute to the physiological plasticity of the endogenous opioid system in response to natural neuropeptides, as well as clinically relevant opiate drugs. Considerable progress has been made in elucidating molecular and cellular mechanisms of opioid receptor regulation. The

Regulations of opioid dependence by opioid receptor types

Pharmacology & Therapeutics, 2001
Three major types of opioid receptors, designated mu, delta, and kappa, are widely expressed in the CNS. Development of selective receptor ligands and recent cloning of each receptor have contributed greatly to our increasing knowledge of the neuropharmacological profile of each opioid receptor type.

Opioid Receptor Assays

Current Protocols in Pharmacology, 1998
AbstractOpioid receptors mediate the pharmacologic actions of morphine‐like analgesics, a class of drugs that are important clinical agents which are also widely abused socially as a result of their euphorogenic and addictive properties. Cloning of the opioid receptors has confirmed the original postulate that there are only three classes of opioid ...

Opioid receptors and pain

Pharmaceutisch Weekblad Scientific Edition, 1990
A receptor site is considered to be a transducing factor for effect of the natural ligand. Endorphins and the drugs that mimic their effects (the opiates) are important for analgesia, and consequently the receptor sites involved in actions of opioid drugs are to be considered as relevant to the transmission of pain.
