The increased number of PD-1+CD8+ T cells shown to be present in non–T cell–inflamed Mgat5-KO tumors as seen in Supplemental Figure 7B further suggests this may be an effective therapy, although no difference in PD-L1 expression on EV and Mgat5-KO tumor cells after stimulation with IFN-γ was observed in vitro (Supplemental Figure 12A). This evidence concerns the gene CD8A and neoplasm.
