Figure 4From: Acetylation at K108 of the NS1 protein is important for the replication and virulence of influenza virusIFN-β antagonism assay. IFN-β antagonistic activity of NS1-wt, NS1-108R and NS1-108Q proteins stimulated by Poly(I:C) (A), pcDNA-RIG-I (B), pcDNA-TBK-1 (C), or IRF3 (D). Each data point indicates the mean ± SEM of three independent experiments, ***P < 0.001, *P < 0.05.Back to article page
