Perspectives on Endogenous Opioids in Birds

Frontiers in Physiology, 2018
The present review summarizes the state of knowledge of endogenous opioids in birds. Endogenous opioid peptides acts in a neuromodulatory, hormonal and paracrine manner to mediate analgesic and other physiological functions.

(α)N-acetyl derivatives of β-endorphin-(1-31) and -(1-27) regulate the supraspinal antinociceptive activity of different opioids in mice

, 2013
(α)N-acetyl human β-endorphin-(1-31) injected icv to mice antagonized the analgesic activity of β-endorphin-(1-31) and morphine whereas the analgesia evoked by DADLE and DAGO was enhanced by this treatment.

Influences of β-endorphins in Ethanol Consumption Patterns and Acquisition of a Conditioned Taste Aversion Mediated by the Drug

Revista Argentina de Ciencias del Comportamiento, 2009
Rewarding effects of ethanol may be mediated in part by endogenous opioids. Ethanol alters β-endorphin synthesis and release. β-endorphin heterozygous (HT) and knockout (KO) mice consume higher levels of a low-concentrated alcohol solution and show ...

Neuroimmunomodulation in Cancer Patients: Correlations between Melatonin and ß-Endorphin Blood Levels and T Helper/Suppressor Ratio

The International Journal of Biological Markers, 1988
The pineal gland and opioid peptides play roles in the neuroendocrine control of immunity. Both neuroendocrine and immune dysfunctions have been observed in cancer but the importance of the altered secretion of neurohormones in the immunoincompetence of ...

Further characterization of (α)N-Acetyl β-endorphin-(1-31) regulatory activity, I: Effect on opioid- and α2-mediated supraspinal antinociception in mice

, 2013
Picomol doses of the acetylated derivative of β- endorphin-(1-31), injected intracerebroventricularly (icv) in mice, reduced the analgesic activity of morphine, etorphine and β-endorphin-(1-31), while the efficiency of DAGO and DADLE in producing ...

The endogenous opioid system in the medial prefrontal cortex mediates ketamine’s antidepressant-like actions

Translational Psychiatry
Recent studies have implicated the endogenous opioid system in the antidepressant actions of ketamine, but the underlying mechanisms remain unclear.

Exposure to nitrous oxide stimulates a nitric oxide-dependent neuronal release of β-endorphin in ventricular-cisternally-perfused rats

, 2009
We have previously shown that the antinociceptive effect of nitrous oxide (N 2O) in the rat hot plate test is sensitive to antagonism by antisera against the endogenous opioid peptide β-endorphin.

Pyrogens Enhance β-Endorphin Release in Hypothalamus and Trigger Fever That Can Be Attenuated by Buprenorphine

Journal of Pharmacological Sciences, 2003
: At first, we investigated whether both β-endorphin release level in the hypothalamus and body temperature can be altered after intracerebroventricular (i.c.v.) injection of either lipopolysaccharide (LPS), interleukin-1β (IL-1β), or prostaglandin E2 ...

Two opposing modes of action of β-endorphin on lymphocyte function

, 1991
Five opioid peptides (α-, β-, and γ-endorphin, methionine- and leukine-enkephalin) were tested for their effect on the concanavalin A-induced proliferative response of splenocytes of adult male F344 rats.

G-CSF treatment increases the number of migrated β-endorphin-containing PMN cells in injured nerves.

, 2013
(A–C) Confocal laser scanning microscopy of PMN cells and β-endorphin peptides in the right sciatic nerve of vehicle-treated sham rats (A1–3), vehicle-treated CCI rats (B1–3), and G-CSF treated CCI rats (C1–3) 12 h after CCI, respectively.
