A decrease in the level of NF-κB inhibitor IκB-α was observed in Fin34-α, Fin32-β, Fin37-δ infected cells at 48 h p.i. and in the Fin40-κ infection already at 24 h p.i. A decrease in IκB-α was also seen in cells infected with Fin3 and Fin22 at 72 h p.i. (Figure 3B). This evidence concerns the gene NFKB1 and infection.
