【 摘 要 】

Multiple myeloma (MM) is a type of cancer characterized by abnormal proliferation of clonal cells; it is the very dangerous and highly prevalent disease. Although significant progress has been made in clinical research, especially with novel drugs such as bortezomib, lenalidomide, and carfilzomib, most of the patients with MM still suffer from often fetal relapses due to drug resistance. In this study, we aimed to develop immune cells that could specifically target and destroy MM cells. Chimeric antigen receptor–modified NK-92 (CAR-NK92) cells have been very effective against B-cell acute lymphoblastic leukemia (B-ALL); as MM shows high expression of CD138, we constructed CD138-directed CAR-NK-92MI cells (CAR-CD138). It 2is reported that there is a small subset of CD138–/CD19+ MM cells showing, to some extent, stem cell qualities. We therefore generated the CD19-directed CAR-NK-92MI cells (CAR-CD19) as well. These two CAR-NK cells showed strong in vitro biological activity in specifically killing target tumor cells. Thus, the concomitant use of these CAR-NK cells may achieve excellent results in vivo.
