Dynorphin-dependent reduction of excitability and attenuation of inhibitory afferents of NPS neurons in the pericoerulear region of mice

open access: yesFrontiers in Cellular Neuroscience, 2016
The Neuropeptide S system, consisting of the 20-amino acid peptide neuropeptide S (NPS) and its G-protein coupled receptor (NPSR), modulates arousal, wakefulness, anxiety, and fear-extinction in mice.

Opioid precursor protein isoform is targeted to the cell nuclei in the human brain [PDF]

open access: yes, 2017
Background: Neuropeptide precursors are traditionally viewed as proteins giving rise to small neuropeptide molecules. Prodynorphin (PDYN) is the precursor protein to dynorphins, endogenous ligands for the kappa-opioid receptor.

Isotalatizidine, a C19-diterpenoid alkaloid, attenuates chronic neuropathic pain through stimulating ERK/CREB signaling pathway-mediated microglial dynorphin A expression

open access: yesJournal of Neuroinflammation, 2020
Background Isotalatizidine is a representative C19-diterpenoid alkaloid extracted from the lateral roots of Aconitum carmichaelii, which has been widely used to treat various diseases on account of its analgesic, anti-inflammatory, anti-rheumatic, and ...

KNDy neurons as an indirect target of insulin‐like growth factor‐1

open access: yesJournal of Neuroendocrinology, Volume 38, Issue 1, January 2026.
Abstract Neurons in the arcuate nucleus of the hypothalamus (ARH) that coexpress kisspeptin, neurokinin B, and dynorphin (KNDy neurons) are considered the gonadotropin‐releasing hormone (GnRH) pulse generator necessary for fertility. KNDy neurons are also metabolic sensors controlling the hypothalamic–pituitary‐gonadal (HPG) axis.

Antianalgesic Action of Dynorphin A Mediated by Spinal Cholecystokinin

open access: yesExperimental Biology and Medicine, 1999
Previous work indicates that the antianalgesic action of pentobarbital and neurotensin administered intracerebroventricularly in mice arises from activation of a descending system to release cholecystokinin (CCK) in the spinal cord where CCK is known to antagonize morphine analgesia.

Exploring the Role of Kisspeptin in Polycystic Ovary Syndrome and Its Associated Pregnancy Complications

open access: yesObesity Reviews, Volume 27, Issue 1, Page 1-21, January 2026.
ABSTRACT Polycystic ovary syndrome (PCOS) is a common endocrine disorder with a complex pathogenesis that includes disordered follicle development, hypothalamic–pituitary–ovarian (HPO) axis dysfunction, hyperandrogenemia, and insulin resistance. The risk of complications during pregnancy, such as gestational diabetes mellitus (GDM) and preeclampsia (PE)

Liquid Chromatography-Electrospray Linear Ion Trap Mass Spectrometry Analysis of Targeted Neuropeptides in Tac1-/- Mouse Spinal Cords Reveal Significant Lower Concentration of Opioid Peptides [PDF]

open access: yes, 2015
Tachykinin and opioid peptides play a central role in pain transmission, modulation and inhibition. The treatment of pain is very important in medicine and many studies using NK1 receptor antagonists failed to show significant analgesic effects in ...

Stress-Induced Reinstatement of Drug Seeking: 20 Years of Progress [PDF]

open access: yes, 2015
In human addicts, drug relapse and craving are often provoked by stress. Since 1995, this clinical scenario has been studied using a rat model of stress-induced reinstatement of drug seeking.

Elevated CSF dynorphin A [1–8] in Tourette's syndrome

open access: yesLife Sciences, 1988
A recent neuropathological study has reported decreased levels of dynorphin A immunoreactivity in striato-pallidal fibers in the brain of a patient with severe Gilles de la Tourette's syndrome (TS). This observation, taken with the neuroanatomic distribution of dynorphin and its broad range of motor and behavioral effects, has led to speculation ...

Dopaminergic, glutamatergic but not opioidergic mechanisms mediate induction of FOS-like protein by cocaethylene [PDF]

open access: yes, 1997
Cocaethylene is a psychoactive metabolite formed\ud during the combined consumption of cocaine and ethanol. As\ud this metabolite has many properties in common with cocaine, it is conceivable that cocaethylene administration may induce the activity of ...
