Significance G protein-coupled receptors are considered to function principally at the cell surface. We present evidence that the δ-opioid receptor (DOPr) signals from endosomes to cause a sustained inhibition of pain. Opioids from the inflamed human and

On the G-protein-coupled receptor heteromers and their allosteric receptor-receptor interactions in the central nervous system: focus on their role in pain modulation [PDF]
The modulatory role of allosteric receptor-receptor interactions in the pain pathways of the Central Nervous System and the peripheral nociceptors has become of increasing interest.

Opioid addiction and overdose are at record levels in the United States. This is driven, in part, by their widespread prescription for the treatment of pain, which also increased opportunity for diversion by sensation-seeking users.

Inhibition of activity of GABA transporter GAT1 by δ-opioid receptor [PDF]
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.

Ingested bovine amniotic fluid enhances morphine antinociception in rats [PDF]
Ingestion by rats of rat placenta or amniotic fluid enhances opioid-mediated, or partly opioid-mediated, antinociception produced by morphine injection, vaginal or cervical stimulation, late pregnancy, and foot shock.

Dopamine-D1 and δ-opioid receptors co-exist in rat striatal neurons [PDF]
Cocaine’s enhancement of dopaminergic neurotransmission in the mesolimbic pathway plays a critical role in the initial reinforcing properties of this drug. However, other neurotransmitter systems are also integral to the addiction process.

Divergent modulation of nociception by glutamatergic and GABAergic neuronal subpopulations in the periaqueductal gray [PDF]
The ventrolateral periaqueductal gray (vlPAG) constitutes a major descending pain modulatory system and is a crucial site for opioid-induced analgesia. A number of previous studies have demonstrated that glutamate and GABA play critical opposing roles in

The Special Issue on Stress and Addiction is concerned with interrelationships between environmental stimuli such as stress and endogenous opioid systems that lead to addiction and other behaviors.

Interactions of the opioid and cannabinoid systems in reward: Insights from knockout studies
The opioid system consists of three receptors, mu, delta, and kappa, which are activated by endogenous opioid peptides (enkephalins, endorphins and dynorphins). The endogenous cannabinoid system comprises lipid neuromodulators (endocannabinoids), enzymes

Many signal transduction systems have an apparent redundancy built into them, where multiple physiological agonists activate the same receptors. Whether this is true redundancy, or whether this provides an as-yet unrecognized specificity in downstream ...
