Neurons derived from human-induced pluripotent stem cells express mu and kappa opioid receptors

open access: yesNeural Regeneration Research, 2021
Neuroprotection studies have shown that induced pluripotent stem (iPS) cells have the possibility to transform neuroprotection research. In the present study, iPS cells were generated from human renal epithelial cells and were then differentiated into ...

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]

open access: yes, 2013
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.

An opioid-like system regulating feeding behavior in C. elegans [PDF]

open access: yes, 2015
Neuropeptides are essential for the regulation of appetite. Here we show that neuropeptides could regulate feeding in mutants that lack neurotransmission from the motor neurons that stimulate feeding muscles. We identified nlp-24 by an RNAi screen of 115

Stress-induced reinstatement of nicotine preference requires dynorphin/kappa opioid activity in the basolateral amygdala [PDF]

open access: yes, 2016
UNLABELLED: The dynorphin (DYN)/kappa-opioid receptor (KOR) system plays a conserved role in stress-induced reinstatement of drug seeking for prototypical substances of abuse.

The Kappa Opioid Receptor: Candidate Pharmacotherapeutic Target for Multiple Sclerosis

open access: yesDrugs and Drug Candidates, 2023
Multiple sclerosis (MS) afflicts millions of people worldwide. While multiple therapeutics have recently been developed and approved as treatment agents, they are not 100% effective.

Buprenorphine added on brief cognitive behavioral therapy for treatment of methamphetamine use disorder [PDF]

open access: yes, 2018
Background: Methamphetamine (MA) use remains a major public health concern around the world. Recent findings suggest that buprenorphine may be helpful for cocaine use reduction. Moreover, animal studies described reduced dopamine peak effect following MA

Alterations in Cortical and Basal Ganglia Levels of Opioid Receptor Binding in a Rat Model of l-DOPA-Induced Dyskinesia

open access: yesNeurobiology of Disease, 2001
Opioid receptor-binding autoradiography was used as a way to map sites of altered opioid transmission in a rat model of l-DOPA-induced dyskinesia. Rats with unilateral 6-hydroxydopamine lesions of the nigrostriatal pathways sustained a 3-week treatment ...

Opioids and opioid receptors; understanding pharmacological mechanisms as a key to therapeutic advances and mitigation of the misuse crisis

open access: yesBJA Open, 2023
Opioids are a mainstay in acute pain management and produce their effects and side effects (e.g., tolerance, opioid-use disorder and immune suppression) by interaction with opioid receptors.

Goshajinkigan reduces bortezomib-induced mechanical allodynia in rats: Possible involvement of kappa opioid receptor

open access: yesJournal of Pharmacological Sciences, 2015
In the present study, we investigated the effect of a Kampo medicine Goshajinkigan (GJG) on the bortezomib-induced mechanical allodynia in von Frey test in rats. The single administration of tramadol (10 mg/kg), GJG (1.0 g/kg) and its component processed

Single high-dose buprenorphine for opioid craving during withdrawal. [PDF]

open access: yes, 2018
BackgroundOpioid use disorder is one of the most prevalent addiction problems worldwide. Buprenorphine is used as a medication to treat this disorder, but in countries where buprenorphine is unavailable in combination with naloxone, diversion can be a ...
