Modulation of Neurally Mediated Vasodepression and Bradycardia by Electroacupuncture through Opioids in Nucleus Tractus Solitarius. [PDF]

open access: yes, 2018
Stimulation of vagal afferent endings with intravenous phenylbiguanide (PBG) causes both bradycardia and vasodepression, simulating neurally mediated syncope.

Berberine Improves Intestinal Motility and Visceral Pain in the Mouse Models Mimicking Diarrhea-Predominant Irritable Bowel Syndrome (IBS-D) Symptoms in an Opioid-Receptor Dependent Manner.

open access: yesPLoS ONE, 2015
Background and aimsBerberine and its derivatives display potent analgesic, anti-inflammatory and anticancer activity. Here we aimed at characterizing the mechanism of action of berberine in the gastrointestinal (GI) tract and cortical neurons using ...

Current evidence for a modulation of low back pain by human genetic variants [PDF]

open access: yes, 2009
The manifestation of chronic back pain depends on structural, psychosocial, occupational and genetic influences. Heritability estimates for back pain range from 30% to 45%. Genetic influences are caused by genes affecting intervertebral disc degeneration

Antinociceptive potency of a fluorinated cyclopeptide Dmt-c[D-Lys-Phe-p-CF3-Phe-Asp]NH2

open access: yesJournal of Enzyme Inhibition and Medicinal Chemistry, 2018
Opioid peptides and opiate drugs such as morphine, mediate their analgesic effects, but also undesired side effects, mostly through activation of the mu opioid receptor.

Biased Signaling of the Mu Opioid Receptor Revealed in Native Neurons

open access: yesiScience, 2019
Summary: G protein-coupled receptors are key signaling molecules and major targets for pharmaceuticals. The concept of ligand-dependent biased signaling raises the possibility of developing drugs with improved efficacy and safety profiles, yet ...

The G protein-coupled receptor heterodimer network (GPCR-HetNet) and its hub components [PDF]

open access: yes, 2014
G protein-coupled receptors (GPCRs) oligomerization has emerged as a vital characteristic of receptor structure. Substantial experimental evidence supports the existence of GPCR-GPCR interactions in a coordinated and cooperative manner.

Comprehensive Mu-Opioid-Receptor Genotyping by Pyrosequencing [PDF]

open access: yesClinical Chemistry, 2004
The human μ-opioid receptor, encoded by the OPRM1 gene (1)(2), is the major site for the analgesic action of opioids. The OPRM1 gene is therefore a first-line candidate for evaluating the role of mutations on the clinical effects of opioids. The mutant allele of the 118A>G single-nucleotide polymorphism (SNP) in the OPRM1 gene, which codes for an ...

Chronic opioid pretreatment potentiates the sensitization of fear learning by trauma. [PDF]

open access: yes, 2020
Despite the large comorbidity between PTSD and opioid use disorders, as well as the common treatment of physical injuries resulting from trauma with opioids, the ability of opioid treatments to subsequently modify PTSD-related behavior has not been well ...

Scalable Production of Highly-Sensitive Nanosensors Based on Graphene Functionalized with a Designed G Protein-Coupled Receptor [PDF]

open access: yes, 2014
We have developed a novel, all-electronic biosensor for opioids that consists of an engineered mu opioid receptor protein, with high binding affinity for opioids, chemically bonded to a graphene field-effect transistor to read out ligand binding.
