Presentation_1_Cellular Profiles of Prodynorphin and Preproenkephalin mRNA-Expressing Neurons in the Anterior Olfactory Tubercle of Mice.PDF

open access: yes, 2022
The olfactory tubercle (OT) is a striatal region that receives olfactory inputs. mRNAs of prodynorphin (Pdyn) and preproenkephalin (Penk), precursors of dynorphins and enkephalins, respectively, are strongly expressed in the striatum. Both produce opioid

Same Fat, Different Consequences? The Association Between Fat Distribution and Vasomotor Menopausal Symptoms Varies by Menopausal Status

open access: yesComprehensive Physiology, Volume 16, Issue 5, October 2026.
Body fat distribution was associated with vasomotor symptoms in a menopausal stage‐specific manner. Greater trunk and abdominal adiposity were linked to more frequent and bothersome symptoms during perimenopause, whereas distinct abdominal adiposity measures showed contrasting associations with symptom burden after menopause.

Lateral olivocochlear neurons contain both enkephalin and dynorphin immunoreactivities: immunocytochemical co-localization studies.

open access: yes, 1988
Antibodies to methionine enkephalin and to dynorphin B were used in an immunocytochemical study examining co-containment of enkephalins and dynorphins in olivocochlear neurons in the guinea pig lateral superior olive.

The Opioid System in Temporal Lobe Epilepsy: Functional Role and Therapeutic Potential

open access: yesFrontiers in Molecular Neuroscience, 2017
Temporal lobe epilepsy is considered to be one of the most common and severe forms of focal epilepsies. Patients often develop cognitive deficits and emotional blunting along the progression of the disease.

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

open access: yesInternational 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 ...

Mobilization of Specific Neuropeptides by Peripheral Stimulation of Identified Frequencies

open access: yes, 1992
Three families of endogenous opioid peptides have been characterized in the CNS: enkephalins, endorphins and dynorphins. These can be mobilized by peripheral electrical stimulation.

Prodynorphin-Derived Opioid Peptides

open access: yes, 2006
The dynorphin family is composed of multiple peptides. They are distributed in the central nervous system and peripheral tissues. Dynorphins dusply several biological functions, including the regulation of pain transmission, feeding, pituitary hormone ...

Imaging mass spectrometry reveals elevated nigral levels of dynorphin neuropeptides in L-DOPA-induced dyskinesia in rat model of Parkinson's disease.

open access: yesPLoS ONE, 2011
L-DOPA-induced dyskinesia is a troublesome complication of L-DOPA pharmacotherapy of Parkinson's disease and has been associated with disturbed brain opioid transmission.

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

open access: yesJournal 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 ...
