Human Mas-related G protein-coupled receptors-X1 induce chemokine receptor 2 expression in rat dorsal root ganglia neurons and release of chemokine ligand 2 from the human LAD-2 mast cell line [PDF]

open access: yes, 2013
Primate-specific Mas-related G protein-coupled receptors-X1 (MRGPR-X1) are highly enriched in dorsal root ganglia (DRG) neurons and induce acute pain. Herein, we analyzed effects of MRGPR-X1 on serum response factors (SRF) or nuclear factors of activated

Comprehensive Insights into Natural Bioactive Compounds: From Chemical Diversity and Mechanisms to Biotechnological Innovations and Applications

open access: yesChemistryOpen, EarlyView.
Natural products derived from plants, animals, fungi, bacteria, and minerals contain diverse bioactive classes such as alkaloids, flavonoids, terpenoids, saponins, tannins, and phenolics. These natural products work through different mechanisms, including ROS inhibition, NF‐κB suppression, and cytokine regulation, and exhibit wide applications across ...

Differential stability of the crystallographic interfaces of mu- and kappa-opioid receptors. [PDF]

open access: yesPLoS ONE, 2014
The recent mu-opioid receptor (MOPr) and kappa-opioid receptor (KOPr) crystal structures have inspired hypotheses of physiologically relevant dimerization contacts, specifically: a closely packed interface involving transmembrane (TM) helices TM5 and TM6,

Orvinols with Mixed Kappa/Mu Opioid Receptor Agonist Activity [PDF]

open access: yesJournal of Medicinal Chemistry, 2013
Dual-acting kappa opioid receptor (KOR) agonist and mu opioid receptor (MOR) partial agonist ligands have been put forward as potential treatment agents for cocaine and other psychostimulant abuse. Members of the orvinol series of ligands are known for their high binding affinity to both KOR and MOR, but efficacy at the individual receptors has not ...

Evaluation of Potential Hormonal Activities of Ashwagandha (Withania somnifera)

open access: yesPhytotherapy Research, EarlyView.
ABSTRACT Ashwagandha is a widely used herb in traditional medicine systems, particularly Ayurveda. Despite its extensive tradition, growing concerns regarding its potential endocrinological effects have prompted scientific scrutiny. This review systematically evaluates the current preclinical, clinical, and case study evidence concerning AS's effects ...

Placenta ingestion by rats enhances d- and k-opioid antinociception, but suppresses m-opioid antinociception [PDF]

open access: yes, 2004
Ingestion of placenta or amniotic fluid produces a dramatic enhancement of centrally mediated opioid antinociception in the rat. The present experiments investigated the role of each opioid receptor type (m, d, k) in the antinociception-modulating ...

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.

Effect of butorphanol in combination with xylazine during castration of calves: A randomised trial under field conditions

open access: yesVeterinary Record, EarlyView.
Abstract Background In horses, cats and dogs, the opioid butorphanol has been proven effective in management of visceral pain and for peri‐ and postoperative pain relief. The aim of this study was to evaluate physiological responses and indicators of noxious stimuli when adding butorphanol to xylazine for sedation of bull calves during surgical ...

Involvement of Peripheral Beta-Endorphin and MU, Delta, Kappa Opioid Receptors in Electro Acupuncture Analgesia for Prolonged Inflammatory Pain of Rats

open access: yesEuropean Journal of Inflammation, 2013
Acupuncture is commonly used to relieve chronic pain worldwide. Accumulating evidence shows that peripheral opioid system plays an important role in inhibiting inflammatory pain. This study aimed to investigate the involvement of peripheral opioid system

A Review of the Therapeutic Potential of Recently Developed G Protein-Biased Kappa Agonists

open access: yesFrontiers in Pharmacology, 2019
Between 2000 and 2005 several studies revealed that morphine is more potent and exhibits fewer side effects in beta-arrestin 2 knockout mice. These findings spurred efforts to develop opioids that signal primarily via G protein activation and do not, or ...
