CD19 and Burkitt lymphoma: Besides that, in another study, CD20-specific CAR-NK-92 injected directly into subcutaneous Daudi (Burkitt’s lymphoma) lymphoma xenografts suppressed local tumor development more effectively than CD19-specific CAR-NK-92 [158]., and in a subcutaneous Raji Burkitt’s lymphoma xenograft in a mouse model, CAR-modified CIK cells revealed potent antitumor activity and remarkably controlled disease development [155].
