Abstract: Provided herein are modified NK-92 cells comprising a nucleic acid encoding C—C chemokine receptor type 7 (CCR7) operably linked to a promoter. Optionally, the cells further comprise a nucleic acid encoding C—C motif ligand 21 (CCL21), a nucleic acid encoding C—C motif ligand 19 (CCL19) or a combination thereof. Also provided are compositions and kits comprising the modified NK-92 cells. Provided are methods of making the modified cells and methods of treating cancer using the cells.

Abstract: Provided herein are methods for inducing and maintaining an immune response to a tumor in a subject while treating a primary tumor. The methods include administering to the subject an effective amount of CAR-expressing-NK-92 cells to treat the primary tumor thereby inducing an anti-tumor immune response that is maintained in the subject, the maintained immune response preventing tumor regrowth and/or inhibiting generation of secondary tumors. Also provided are methods of producing an anti-tumor vaccine in a subject with a tumor. The methods include administering to the subject an effective amount of CAR-expressing-NK-92 cells to the subject thereby inducing an anti-tumor vaccine to the tumor in the subject.
