IFNL2 and infection: HRV-16 pre-infection with MOIs of 0.5 and 0.1 (but not 0.01) significantly boosted IFNL2 expression by AECs infected with either SARS-CoV-2 WA-01 or the Delta variant, while only an HRV-16 pre-infection with an MOI of 0.5 boosted IFNL2 expression by AECs infected with the Omicron variant (MOI 0.5) (Supplementary Fig. 1D).
