Abstract

Provided for herein in several embodiments are immune cell-based (e.g., natural killer (NK) cell) compositions comprising CD19-directed chimeric antigen receptors. In some, embodiments the anti-CD19 binder portion of the CAR is humanized. In several embodiments, the humanized anti-CD19 CAR expressing cells exhibit enhanced expression of the CAR as well as enhanced cytotoxicity and/or persistence. Several embodiments include methods of using of the anti-CD19 CAR expressing immune cells in immunotherapy.
