Heterodimerization of apelin receptor and neurotensin receptor 1 induces phosphorylation of ERK1/2 and cell proliferation via Gαq-mediated mechanism [PDF]

open access: yes, 2014
Dimerization of G protein-coupled receptors (GPCRs) is crucial for receptor function including agonist affinity, efficacy, trafficking and specificity of signal transduction, including G protein coupling.

Effects of Electroacupuncture at ST36 on Visceral Pain and Inflammatory Markers in IBS Rats

open access: yesNeurogastroenterology &Motility, EarlyView.
Electroacupuncture (EA) at ST36 significantly reduced visceral pain and colonic inflammation in IBS model rats. EA increased pain thresholds, lowered AWR scores, and downregulated key inflammatory mediators (IL‐1β, IL‐6, TNF‐α, TRPV1, NF‐κB). These findings highlight ST36‐targeted EA as a promising therapeutic strategy for IBS visceral hypersensitivity

Opioid Receptors Gene Polymorphism and Heroin Dependence in Iran

open access: yesBasic and Clinical Neuroscience, 2018
Introduction: Genes often have multiple polymorphisms that interact with each other and the environment in different individuals. Variability in the opioid receptors can influence opiate withdrawal and dependence.

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

open access: yesFrontiers in Molecular Neuroscience, 2017
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

GABAB receptor‐mediated modulation of sensory neuron excitability: Roles of CaV2.2, G‐protein‐coupled inwardly rectifying potassium (GIRK) channels, and hyperpolarisation‐activated cyclic nucleotide‐gated (HCN) channels in human and mouse nociception

open access: yesExperimental Physiology, EarlyView.
Abstract Chronic visceral pain is a key symptom of irritable bowel syndrome. Modulation of voltage‐gated calcium and potassium channels by G protein‐coupled receptors plays a key role in dampening nociceptive transmission. Both baclofen and the analgesic peptide α‐conotoxin Vc1.1 activate GABAB receptors (GABABR), resulting in inhibition of CaV2.2 and ...

M3 muscarinic acetylcholine receptor facilitates the endocytosis of mu opioid receptor mediated by morphine independently of the formation of heteromeric complexes [PDF]

open access: yes, 2017
Morphine inefficiency to induce the internalization of mu opioid (MOP) receptors observed in numerous experimental models constitutes a paradigm of G-protein coupled receptor (GPCR) functional selectivity.

Local Anesthetics in Cancer: Mechanisms and Translational Perspectives

open access: yesMedComm – Oncology, Volume 5, Issue 1, March 2026.
Local anesthetics demonstrate multifaceted antitumor effects that collectively contribute to cancer suppression. Beyond canonical sodium channel blockade, these agents exert the following pharmacological actions: inhibition of tumor cell proliferation, suppression of migration and invasion, induction of proapoptotic pathways, attenuation of ...

The biopsychology of maternal behavior in nonhuman mammals [PDF]

open access: yes, 1990
The term “maternal behavior,” when applied to nonhuman mammals, includes the behaviors exhibited in preparation for the arrival of newborn, in the care and protection of the newly arrived young, and in the weaning of those young, and represents a complex

Behavioral meaningful opioidergic stimulation activates kappa receptor gene expression

open access: yesBrazilian Journal of Medical and Biological Research, 2012
The periaqueductal gray (PAG) has been reported to be a location for opioid regulation of pain and a potential site for behavioral selection in females.

Esketamine/Ketamine: Dual‐Action Mechanisms and Clinical Prospects beyond Anesthesia in Psychiatry, Immunology, and Oncology

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Esketamine and ketamine are widely used for perioperative analgesia and anesthesia. Despite their established roles in analgesia, sedation, and anesthesia, as well as emerging antidepressant, anti‐tumor, and anti‐inflammatory effects, their clinical use is limited due to side effects and addiction potential.
