IFI6 and infection: To analyze whether IFI6 is induced after the infection with respiratory viruses, such as influenza and coronaviruses, lung adenocarcinoma-derived A549 and A549 cells overexpressing the SARS-CoV-2 receptor hACE-2, were infected with IAV (MOI 3) or SARS-CoV-2 (MOI 1), respectively.
