Overview

DKO CAR CB-NK cells are an experimental, allogeneic cell therapy consisting of cord blood-derived natural killer (NK) cells engineered with a chimeric antigen receptor (CAR) and modified via CRISPR/Cas9 gene editing. The cells express a CAR targeting B-cell maturation antigen (BCMA) with a 4-1BB costimulatory domain. The "DKO" (double knockout) designation refers to the simultaneous disruption of the KLRC1 gene (encoding the inhibitory receptor NKG2A) and the TGFBR2 gene (encoding the TGF-β receptor II). These genetic modifications are intended to enhance the cells' persistence and cytotoxic activity by making them resistant to immunosuppressive signals within the tumor microenvironment, such as the HLA-E/NKG2A axis and soluble TGF-β. The therapy is being developed by researchers at the Hospital 12 de Octubre and CIEMAT for the treatment of multiple myeloma.
