Interestingly, at the early phase of infection (24 hpi), MoDCs infected with WNVNY99 had reduced levels of vRNA (p < 0.05, Figure 2a), IFNβ mRNA (Figure 2b),OAS1 mRNA (Figure 2c) and MxA mRNA (Figure 2d) compared to MoDCs infected with WNVNSW2011. This evidence concerns the gene IFNB1 and infection.
