Infection with influenza B virus induces faster IFN expression than infection with type A virus. (A) IFN-λ1 gene expression was analyzed in moDCs infected with influenza A/Beijing/353/89 and B/Shangdong/7/97 viruses at serial dilutions (MOIs of 125 to 0.2) for 16 h. (B) IFN-λ1 gene expression at different time points in A549 cells infected with the above-described viruses at an MOI of 2. (C) The same experiment was repeated with recombinant virus strains A/Udorn/307/72 and B/Yamagata/16/88 in moDCs at an MOI of 5, and IFN-λ1 gene expression was analyzed. All these experiments were repeated twice.
