... that the activation of IRF-3 by M-pIC treatment is mediated by the TLR3 ⁄ TRIF signaling pathway. We obtained further evidence by examining the status of the phos- phorylation and dimerization of ... cells. First, we confirmed the effect of NS3-4A on the activation of the IFN-b gene promoter by the Cardif exogenously expressed in PH5CH8 cells. The results of the...
