New vaccines research from Emory Vaccine Center outlined
November 26th, 2008
According to a study from the United States, "Robust production of type I interferon (IFN-alpha/beta) in plasmacytoid dendritic cells (pDCs) is crucial for antiviral immunity. Here we show involvement of the mammalian target of rapamycin ( mTOR) pathway in regulating interferon production by pDCs." "Inhibition of mTOR or its 'downstream' mediators, the p70 ribosomal S6 protein kinases p70S6K1 and p70S6K2, during pDC activation by Toll-like receptor 9 (TLR9) blocked the interaction of TLR9 with the adaptor MyD88 and subsequent activation of the interferon-regulatory factor IRF7, which resulted in impaired IFN-alpha/beta production. Microarray analysis confirmed that...
