Therefore, the 19 genes are common in 24-h infection models of the different respiratory infection viruses, and that includes IFI6, IFIT1, MX1, IRF9, IRF7, OAS1, IFIH1, IFI27, PLSCR1, OAS2, IFITM1, CXCL2, IFI44, PTGS2, BCL2A1, CXCL3, XAF1, and EDN1. The heat map of the thirty-one significant genes was reported in Fig. 2B and has shown the same tendency (Table 1) in the original analysis reported by Blanco-Melo et al. (2020), though the statistical parameters found to vary. Here, IRF9 is linked to respiratory tract infectious disorder.
