Highly redundant neuropeptide volume co-transmission underlying episodic activation of the GnRH neuron dendron

eLife, 2021
The necessity and functional significance of neurotransmitter co-transmission remains unclear. The glutamatergic ‘KNDy’ neurons co-express kisspeptin, neurokinin B (NKB), and dynorphin and exhibit a highly stereotyped synchronized behavior that reads out

Use of Platelet‐Rich Fibrin (PRF) on Palatal Wound Healing: A Narrative Review With Clinical Recommendations

Journal of Periodontal Research, EarlyView.
Based on the available evidence, the application of platelet‐rich fibrin (PRF) following free gingival graft (FGG) and subepithelial connective tissue graft (SCTG) harvesting appears to be a promising approach for enhancing wound healing, minimizing postoperative complications, and reducing analgesic consumption. ABSTRACT This clinical narrative review

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

Microvascular endothelial function is blunted in postmenopausal females with frequent hot flushes

Experimental Physiology, EarlyView.
Abstract Hot flushes of menopause are associated with elevated blood pressure (BP) and diminished macrovascular endothelial function, an initiating factor in the onset of atherosclerosis. Whether microvascular endothelial function is impaired in females with hot flushes, however, remains unknown.

Hepatoprotective effect of opioid peptides in stress [PDF]

Research Results in Pharmacology, 2019
Introduction: Influence of the endogenous opioid system on the liver has not been studied enough. To understand the damaging effects of stress on the liver and the hepatoprotective effects of opioids, a study was performed on stress-resistant and stress ...

Mitochondrial control of ciliary gene expression and structure in striatal neurons

The Journal of Physiology, EarlyView.
Abstract figure legend Neurons drive animal behaviour by receiving and transmitting information and require energy, primarily supplied by mitochondria, to function. Additionally, neurons need to sense environmental changes to adapt, a function that is locally played by the primary cilia.

Influence of neurokinin B, dynorphin A and kisspeptin-10 on in vitro gonadotropin secretion by anterior pituitary cells isolated from pubescent ewes

Journal of Veterinary Research
The hypothalamic neuropeptides kisspeptin-10 (KiSS-10), neurokinin B (NKB), and dynorphin A (Dyn A) play roles in the endocrine regulation of the hypothalamic–pituitary–ovarian (HPO) axis in puberty.

Systematic profiling reveals broad G protein coupling and context‐dependent modulation of cyclic AMP by the orphan receptor GPR139

British Journal of Pharmacology, Volume 183, Issue 23, Page 6865-6882, December 2026.
Background and Purpose G protein‐coupled receptors (GPCRs) are major drug targets, yet many orphan receptors remain poorly characterized. GPR139 has been implicated in CNS disorders, including schizophrenia and depression, but its signalling mechanisms remain unclear.

Region-specific changes in prodynorphin mRNA and ir-dynorphin a levels after kindled seizures

, 1999
The opioid peptide dynorphin is thought to be implicated in specific types of seizures. In particular, complex partial seizures have been shown to cause release of dynorphin, activation of prodynorphin gene expression, and new peptide synthesis in the ...

Bulleyaconitine A Exerts Antianxiety and Antivisceral Hypersensitivity Effects

Frontiers in Pharmacology, 2020
Visceral pain is one of the leading causes for abdominal pain in gastroenterological diseases and is still hard to treat effectively. Bulleyaconitine A (BAA) is an aconitine analog and has been used for the treatment of pain.
