Pain-related behavioral and electrophysiological actions of dynorphin A (1-17)

Molecular Pain, 2023
Dynorphin A (1-17) (DynA17) has been identified as a key regulator of both sensory and affective dimensions of chronic pain. Following nerve injury, increases in DynA17 have been reported in the spinal and supraspinal areas involved in chronic pain ...

Hormone therapy (HT) in women with premature ovarian insufficiency or early menopause: Time to think of a new paradigm for healthy aging. A joint FIGO and IMS position paper

International Journal of Gynecology &Obstetrics, Volume 175, Issue 1, Page 26-47, October 2026.
Abstract Premature ovarian insufficiency (POI) and early menopause (EM) affect millions of women worldwide. Compared with normal menopause, they confer a longer duration of estrogen deficiency and are associated not only with a shorter lifespan, but with a reduced healthspan, owing to an increased risk of cardiovascular, skeletal, cognitive and ...

The efficacy of Dynorphin fragments at the kappa, mu and delta opioid receptor in transfected HEK cells and in an animal model of unilateral peripheral inflammation

, 2017
Background Dynorphin 1–17 is an endogenous peptide that is released at sites of inflammation by leukocytes, binding preferentially to κ-opioid receptors (KOP) to mediate nociception.

Divergent effects of hyperandrogenemia on the female reproductive neuroendocrine axis under different physiological conditions

Journal of Neuroendocrinology, Volume 38, Issue 10, October 2026.
Abstract The hypothalamic–pituitary–gonadal (HPG) axis coordinates reproductive function and incorporates gonadal sex steroid feedback to regulate gonadotropin secretion in a homeostatic manner. In females, ovarian estrogens and progestins act as the primary negative feedback signals to suppress luteinizing hormone (LH) release, whereas in males ...

Regional distribution of dynorphin and neo-endorphin peptides in rat brain, spinal cord, and pituitary

, 1983
Five products of the dynorphin gene--alpha-neo-endorphin, beta-neo- endorphin, dynorphin A, dynorphin A-(1-8), and dynorphin B--were measured in various regions of rat brain and in rat spinal cord and pituitary.

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.

[3H] dynorphin binding to guinea pig and rat brain

, 1983
[3H] Dynorphin can be shown to bind to the brains of both rat and guinea pigs with approximately 50% specific binding. Characterization of the binding in terms of multiple opiate receptor types supports the kappa selectivity of dynorphin in guinea pig ...

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 ...
