IFNG and neoplasm: The scanned ELISPOT plates of BCMA-positive tumor cell lines KMS-11, KMS-18, and U266 showed that while there were almost no spots after the co-culturing with the control Vγ9Vδ2 T cells transfected with mGFP RNA CAR, high numbers of IFN-γ-positive spots were observed with BCMA-specific CAR-equipped Vγ9Vδ2 T cells (Fig 3A).
