title: Role of beta-endorphin in the regulation of proinflammatory cytokine production by peripheral blood monocytes in vitro.
abstract: beta-Endorphin activated interleukin-1beta production in the culture of unfractionated cells with lipopolysaccharide, but had no effect on the synthesis of tumor necrosis factor-alpha and interleukin-6. This peptide produced a slight stimulatory effect on spontaneous production of interleukin-1beta by cultured leukocytes. Opioid receptor blockade with naloxone and naltrindole did not abolish the stimulatory effect of beta-endorphin on interleukin-1beta production. beta-Endorphin did not modulate the synthesis of interleukin-1beta, tumor necrosis factor-alpha, and interleukin-6 in a purified fraction of monocytes.
