IFNG and infection: Most importantly, we found that the supernatants collected from human iNKT cell lines stimulated with CD1d-transfected Hela cells in the presence of 7DW8-5, but not PE, were able to significantly inhibit ic-SARS-CoV-2-mNeonGreen65 infection in Huh7 cells in vitro66, and that this inhibition was completely abolished when neutralizing anti-human IFN-γ Ab was added to the culture (Supplementary Fig. 8d).
