Reported results showed the efficacy of this approach in an in vivo model of tumor escape where BCMA+TACI− and BCMA−TACI+ cells were equally killed by CAR-T cells, whereas scFv bearing CAR-T cells against BCMA only was insufficient to prevent the outgrowth of BCMA-negative tumor (63). Here, TNFRSF17 is linked to neoplasm.
