CD19 and lymphoma: Moreover, cytotoxicity of dual-CAR NK-92 cells towards the Daudi lymphoma cell line, expressing both CD19 and BCMA, was high (80.1 ± 3.4%) and compared favorably to that of their single antigen-expressing counterparts (CD19-CAR NK-92 and BCMA-CAR NK-92: 75.2 ± 4.7% and 56.5 ± 0.4%, respectively), confirming that dual-CAR loading is not detrimental to the cytotoxic function (Fig. 1F).
