Compared with those in the PRV-GFP infection control group, the viral titers in the groups in which cGAS, cGASΔN, and UniSTING were present were significantly lower (p < 0.001), whereas the viral titer in the IFN-α plasmid group was extremely low (p < 0.0001) (Figure 2D). Here, IFNA1 is linked to infection.
