Allogeneic Anti-CD70-CAR-IL-15-transduced Cord Blood-derived Natural Killer Cells
allogeneic anti-cd70-car-il-15-transduced cord blood-derived natural killer cells
"A preparation of allogeneic, umbilical cord blood (CB)-derived natural killer cells (NKs) that have been engineered to express a chimeric antigen receptor (CAR) specific for the tumor-associated antigen (TAA) human cluster of differentiation 70 (CD70) and interleukin-15 (IL-15), with potential immunostimulating and antineoplastic activities. Upon administration, the allogeneic anti-CD70-CAR-IL-15-transduced CB-derived NK cells target, bind to and induce selective cytotoxicity in CD70-expressing tumor cells. CD70, the ligand for the costimulatory receptor CD27, is overexpressed on the surfaces of various cancer cell types. IL-15 is a pro-survival cytokine that promotes persistence of multiple lymphocyte lineages and potentiates the immune response against tumor cells."
