As shown in Fig 8B, wild-type and rFCV 2280 infection contributed to a 70–80% reduction in IFNAR1 mRNA expression, but rFCV 2280 F9-p30 infection only contributed to a 20–30% reduction; wild-type and rFCV F9 infection contributed to a 10–15% reduction of IFNAR1 mRNA expression, but rFCV F9-2280 p30 infection contributed to a 70–80% reduction. This evidence concerns the gene IFNAR1 and infection.
