Cocaine Reduces the Neuronal Population While Upregulating Dopamine D2-Receptor-Expressing Neurons in Brain Reward Regions: Sex-Effects

Frontiers in Pharmacology, 2021
Addiction to cocaine is associated with dysfunction of the dopamine mesocortical system including impaired dopamine-2 receptor (D2r) signaling. However, the effects of chronic cocaine on neuronal adaptations in this system have not been systematically ...

Endogenous dynorphin protects against neurotoxin-elicited nigrostriatal dopaminergic neuron damage and motor deficits in mice

Journal of Neuroinflammation, 2012
Background The striato-nigral projecting pathway contains the highest concentrations of dynorphin in the brain. The functional role of this opioid peptide in the regulation of mesencephalic dopaminergic (DAergic) neurons is not clear.

Avian opioid peptides: evolutionary considerations, functional roles and a challenge to address critical questions

Frontiers in Physiology, 2023
The present review considers the putative hormonal opioid peptides in birds. In birds and all other vertebrates, there are four opioid related genes encoding a series of peptides.

Advent of NK3R Antagonists for the Treatment of Menopausal Hot Flushes: A Narrative Review

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT The menopause transition is marked by symptoms predominantly attributed to declining oestrogen levels. Approximately 80% of women experience associated symptoms, and 25% experience severe symptoms. The commonest are vasomotor symptoms (VMS), collectively referring to hot flushes and/or night sweats.

Pathobiology of dynorphins in trauma and disease [PDF]

Frontiers in Bioscience, 2005
Dynorphins, endogenous opioid neuropeptides derived from the prodynorphin gene, are involved in a variety of normative physiologic functions including antinociception and neuroendocrine signaling, and may be protective to neurons and oligodendroglia via their opioid receptor-mediated effects. However, under experimental or pathophysiological conditions

Factors Associated With Non‐Vasomotor Menopause Symptoms Experienced by 7285 Women: A UK‐Wide National Survey

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective To investigate the factors associated with non‐vasomotor menopause symptoms among women in the UK, focusing on the perceived importance of specific symptoms and their association with demographic and treatment‐related factors. Design A cross‐sectional online survey.

In silico prediction of novel effective combinational treatment of chronic pain in individual patients: A joint white paper of the H2020 QSPainRelief consortium

British Journal of Pharmacology, EarlyView.
Abstract Opioids are prescribed widely for chronic pain despite well‐recognised risks and variable long‐term benefit, reflecting the lack of effective alternatives for many patients. Combination therapies offer a promising strategy to enhance efficacy whilst reducing side effects.

Ginsenoside Re protects methamphetamine-induced dopaminergic neurotoxicity in mice via upregulation of dynorphin-mediated κ-opioid receptor and downregulation of substance P-mediated neurokinin 1 receptor

Journal of Neuroinflammation, 2018
Background We previously reported that ginsenoside Re (GRe) attenuated against methamphetamine (MA)-induced neurotoxicity via anti-inflammatory and antioxidant potentials.
