Xylazine is an agonist at kappa opioid receptors and exhibits sex-specific responses to opioid antagonism

Addiction Neuroscience
Xylazine is in the unregulated drug supply at increasing rates, usually combined with fentanyl, necessitating understanding of its pharmacology. Despite commentary from politicians, and public health officials, it is unknown how xylazine impacts naloxone

Epigenetic mechanisms and therapeutic innovations in chronic pain‐associated neuropsychiatric co‐morbidities

British Journal of Pharmacology, EarlyView.
Abstract Chronic pain, marked by nociceptive sensitization and maladaptive neuroplasticity, affects 30% of the global population with escalating socioeconomic burdens. Epidemiological data show a 2‐3‐fold increase in neuropsychiatric co‐morbidities among individuals with chronic pain, where epigenetic dysregulation serves as a key mechanism linking ...

Down-regulation of serotonergic genes expression in the raphe nuclei of midbrain under chronic social defeat stress in male mice [PDF]

, 2011
Background: There is ample experimental evidence supporting the hypothesis that the brain serotonergic system is involved in the control of chronic social defeat stress (CSDS), depression and anxiety.

Novel therapeutic targets for chronic visceral pain in gastrointestinal disorders

British Journal of Pharmacology, EarlyView.
Chronic visceral pain imposes a major clinical challenge in gastroenterology and beyond, profoundly impacting patients' quality of life. However, limited understanding of its complex, multifaceted pathophysiology, encompassing both peripheral and central mechanisms, continues to impede the development of effective management strategies.

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.

Opioids in breast cancer: Between analgesia and modulation of tumour progression

British Journal of Pharmacology, EarlyView.
Preclinical investigations consistently demonstrate that activation of μ‐opioid receptors and δ‐opioid receptors promote proliferation, migration, angiogenesis, epithelial‐mesenchymal transition, acquisition of cancer stem cell phenotypes, and chemoresistance.

Dopaminergic, glutamatergic but not opioidergic mechanisms mediate induction of FOS-like protein by cocaethylene [PDF]

, 1997
Cocaethylene is a psychoactive metabolite formed\ud during the combined consumption of cocaine and ethanol. As\ud this metabolite has many properties in common with cocaine, it is conceivable that cocaethylene administration may induce the activity of ...

Cebranopadol, a Mixed Opioid Agonist, Reduces Cocaine Self-administration through Nociceptin Opioid and Mu Opioid Receptors [PDF]

, 2017
Cocaine addiction is a widespread psychiatric condition still waiting for approved efficacious medications. Previous studies suggested that simultaneous activation of nociceptin opioid (NOP) and mu opioid (MOP) receptors could be a successful strategy to

Delta-opioid receptor analgesia is independent of microglial activation in a rat model of neuropathic pain.

PLoS ONE, 2014
The analgesic effect of delta-opioid receptor (DOR) ligands in neuropathic pain is not diminished in contrast to other opioid receptor ligands, which lose their effectiveness as analgesics.
