We first validated that our L1210ImP-KO cells could not induce PSMB8, 9 and 10 following IFNγ stimulation (Figure 5B) and that their proliferation (Supplementary Materials Figure S7A), oVSV production upon infection (Supplementary Materials Figure S7B), IFNα and IFNβ production capacities (Supplementary Materials Figure S7C,D) and responses (Supplemental Figure S7E) were similar to L1210ctrl cells. This evidence concerns the gene IFNA1 and infection.
