After 7 days of culture with DEG, murine OT1 CD8+ T cells were more proficient at killing ovalbumin (OVA)-expressing B16F10-OVA cancer cells (Fig. 5b), while DEG-treated human CD19+ CAR T cells secreted more interferon-γ (IFNγ) and exhibited increased cytotoxicity against CD19+ Raji cells (Fig. 5c). This evidence concerns the gene CD8A and cancer.
