A 3-year-old boy had recurrent episodes of lethargy, encephalopathy, and hepatomegaly accompanied by hypoglycemia, elevated liver aminotransferase and creatine kinase values, and nonketotic dicarboxylic aciduria; the serum carnitine level was…
Neuropeptides, initially thought to be common features of gut and brain, are only synthesized in immune cells and modulate immune functions. The presence and possible functions of these peptides in immune cells in both physiological or pathological…
Proopiomelanocortin (POMC)-derived beta-endorphin1-31 (END) released from immune cells inhibits inflammatory pain. We examined the expression of END and POMC mRNA encoding the signal sequence required for entry of the nascent polypeptide into the…
A number of recent studies suggest that cells of the immune system, e.g. peripheral blood mononuclear cells (PBMC), can synthesize and process POMC and secrete POMC-derived peptides, such as ACTH and endorphins, upon immune and hormonal challenges.…
