Representative fluorescence activated cell sorter (FACS) plots of 5-hour intracellular cytokine expression by tumor-activated CAR T cells show that both C4 and MOv19 CAR T cells produce IFN-γ, TNF-α and IL-2 cytokines when incubated overnight with αFRpos SKOV3 ovarian cancer cells, but MOv19 CAR T cells produced less of these cytokines than C4 CAR T cells (Figure 4D). This evidence concerns the gene TNF and ovarian cancer.
