BACKGROUND: Alcohol abuse may involve an altered neuroendocrine response that mediates lymphocyte-derived proopiomelanocortin (POMC) production and inflammation. We investigated POMC messenger RNA (mRNA) expression in human lymphocytes ex vivo and…
The opiate-like peptide beta-endorphin and adrenocorticotropin are concomitantly secreted in increased amounts by the adenohypophysis in response to acute stress or long-term adrenalectomy as well as in vitro in response to purified corticotropin…
Basal and dexamethasone-suppressed adrenal glucocorticoid secretion and hypothalamic beta-endorphin (BE) release in vitro were investigated in rats deprived of food for 24, 48, 72, and 96 h. Fasting for up to 48 h neither caused significant changes…
Localized inflammation of a rat's hindpaw elicits an accumulation of beta-endorphin-(END) containing immune cells. We investigated the production, release, and antinociceptive effects of lymphocyte-derived END in relation to cell trafficking. In…
