Extended Data Fig. 5. Impact of IFN-ɣ on SARS-CoV-2 replication in BALF macrophages.

Extended Data Fig. 5

(a) Confocal microscopy images show the intracellular accumulation of SARS-CoV-2 dsRNA in BALF CD64+ Mac from WTM and OM at ≥221 days p.i., cultured with or without IFN-γ. DAPI (nucleus) is in purple, and anti-dsRNA staining (SARS-CoV-2 dsRNA) is in red. (b) Measurement of SARS-CoV-2 dsRNA MFI in CD64+ Macs isolated from BALF of WTM, and OM at ≥221 days p.i., cultured with or without IFN-γ. (c) Confocal microscopy images depict MHC-E localization in BALF CD64+ Macs from WTM and OM at ≥221 days p.i., cultured with or without IFN-γ stimulation. DAPI (nucleus) is in blue, anti-dsRNA staining (SARS-CoV-2 dsRNA) is in red, and anti-MHC-E staining is in green. (d) Measurement of MHC-E MFI in CD64+ Macs isolated from BALF of WTM, and OM at ≥221 days p.i., cultured with or without IFN-γ. In each graph, median and interquartile range are shown. p-Values were determined using a 2-way ANOVA test with Šídák’s multiple comparisons test correction.
