Ethanolamine plasmalogens increase luteinising hormone pulsatility and are associated with GPR61 expression in bovine gonadotrophin‐releasing hormone neurons

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Ethanolamine plasmalogens increased LH pulse frequency. GPR61 was expressed in GnRH neurons and gonadotrophs, suggesting a role in neuroendocrine regulation. Ethanolamine plasmalogens (EPls), but not choline plasmalogens (CPls), may act via GPR61 expressed in GnRH neurons in the preoptic area and in anterior pituitary gonadotrophs.

Characterization of endoproteolytic processing of dynorphins by proprotein convertases using mouse spinal cord S9 fractions and mass spectrometry

, 2016
Dynorphins are important neuropeptides with a central role in nociception and pain alleviation. Many mechanisms regulate endogenous dynorphin concentrations, including proteolysis.

Acute ayahuasca administration attenuates binge‐like eating and anxiety‐related behaviors in mice subjected to intermittent fasting

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract Human binge eating disorder is characterized by recurrent episodes of excessive food consumption accompanied by loss of control and is strongly associated with alterations in reward processing and emotional regulation. Ayahuasca, a psychoactive botanical preparation traditionally used in Amazonian medicine, has been shown to modulate ...

The endogenous opioid system in human alcoholics: molecular adaptations in brain areas involved in cognitive control of addiction

, 2011
The endogenous opioid system (EOS) plays a critical role in addictive processes. Molecular dysregulations in this system may be specific for different stages of addiction cycle and neurocircuitries involved and therefore may differentially contribute to ...

Proopiomelanocortin (POMC)–β‐Endorphin System in the Rat Colon: Expression, Up Regulation by Stress, and Correlation With Stress‐Induced Visceral Analgesia

Neurogastroenterology &Motility, Volume 38, Issue 10, October 2026.
This study identified a functional proopiomelanocortin–β‐endorphin system in the rat colon. Peripheral CRF and repeated water avoidance stress increased colonic POMC expression, which was associated with reduced visceral pain. These findings suggest that, outside the pituitary, a CRF‐ and stress‐sensitive enteric POMC–β‐endorphin system may help ...

Role of Opioid Ligands in the Irritable Bowel Syndrome

Canadian Journal of Gastroenterology, 1999
Endogenous opioid peptides – enkephalins, beta-endorphin and dynorphins – are located in specific sites of the brain, the spinal cord, the autonomic ganglia and the enteric nervous system.

Menopausal hormone therapy and comprehensive postmenopausal care in gynecologic cancer survivors: A position paper from the FIGO Committee on Women at Menopausal Age

International Journal of Gynecology &Obstetrics, Volume 174, Issue 3, Page 1151-1171, September 2026.
Abstract Recent advances in cancer screening, diagnosis, and treatment have greatly improved survival rates among women with gynecologic cancers. More survivors now live long enough to experience treatment‐related menopause. Vasomotor symptoms, genitourinary syndrome of menopause, sexual dysfunction, sleep issues, and long‐term risks from estrogen ...

The atypical chemokine receptor ACKR3/CXCR7 is a broad-spectrum scavenger for opioid peptides. [PDF]

, 2020
peer reviewedEndogenous opioid peptides and prescription opioid drugs modulate pain, anxiety and stress by activating opioid receptors, currently classified into four subtypes. Here we demonstrate that ACKR3/CXCR7, hitherto known as an atypical scavenger

Opioid and non-opioid activities of the dynorphins [Elektronisk resurs]

, 2005
Endogenous opioid peptides a-neoendorphin, dynorphin A (Dyn A), dynorphin B (Dyn B) and big dynorphin (Big Dyn) consisting of Dyn A and Dyn B, collectively known as dynorphins are derived from the precursor protein prodynorphin (PDYN).

Upregulated dynorphin opioid peptides mediate alcohol-induced learning and memory impairment

, 2013
The dynorphin opioid peptides control glutamate neurotransmission in the hippocampus. Alcohol-induced dysregulation of this circuit may lead to impairments in spatial learning and memory.
