IFNA1 and infection: In addition, other IFN response genes were present in both AF2122 and G18 gene lists at 6 hpi and 24 hpi but were expressed at higher levels during infection with AF2122 than G18, e.g., radical S-adenosyl methionine domain containing 2 (RSAD2), which was upregulated 17.4- and 19.3-fold at 6 h and 24 h after AF2122 infection, respectively, but only upregulated 3.0- and 2.3-fold after 6 h and 24 h infection with G18, respectively.
