1 In this study, we examined the impact of morphine on IFN-alpha expression in human neuronal cells (NT2-N). Morphine interferon alpha 1 Homo sapiens
2 IFN-alpha expression in NT2-N cells, however, was inhibited by morphine. Morphine interferon alpha 1 Homo sapiens
3 Naltrexone antagonized the inhibitory effect of morphine on IFN-alpha expression in NT2-N cells. Morphine interferon alpha 1 Homo sapiens
4 The specific mu opioid receptor antagonist, Cys2, Tyr3, Arg5, Pen7-amide (CTAP), also blocked the morphine action on intracellular IFN-alpha expression. Morphine interferon alpha 1 Homo sapiens
5 Investigation of the mechanisms involved in the morphine action showed that although morphine had little effect on the expression of key IFN regulatory factors (IRFs), morphine inhibited IFN-alpha promoter activation and suppressed the expression and phosphorylation of signal transducer and activator of transcription 1 (STAT1) in the neuronal cells. Morphine interferon alpha 1 Homo sapiens
