Q: Abstract: On recognition of influenza virus (Flu) by TLR7, plasmacytoid dendritic cells (pDCs) produce type I IFN in significant amounts. Synthetic TLR7 ligands induce the maturation of pDCs, as evidenced by the expression of costimulatory molecules and the production of proinflammatory cytokines; however, they induce only low-level production of IFN-alpha. To dissect the TLR7 signaling in pDCs and how these different profiles are induced, we studied the effects of 2 TLR7 ligands (Flu and CL097) on the activation of blood-isolated pDCs and the human GEN2.2 pDC cell line. Type I IFN production by pDCs correlates with differential interferon regulatory factor 7 (IRF7) translocation into the nucleus induced by the 2 TLR7 ligands. Surprisingly, with both activators we nevertheless observed the rapid expression of the IFN-inducible genes mxa, cxcl10, and trail within 4 hours of stimulation. This expression, controlled by STAT1 phosphorylation, was independent of type I IFN. STAT1 activation was found to be strictly dependent on the PI3K-p38MAPK pathway, showing a new signaling pathway leading to rapid expression of IFN-inducible genes after TLR7 triggering. Thus, pDCs, through this unusual TLR7 signaling, have the capacity to promptly respond to viral infection during the early phases of the innate immune response..
