Natural killer (NK) cells are innate lymphoid cells that are crucial for host defense from viral infections and tumor cells. The ability of NK cells to recognize and kill malignant cells provides a strong premise to advance them as a cellular therapy in the clinical setting. While NK cell-based therapies are being explored in clinical trials, issues with persistence and in vivo functionality have been identified as limitations to their clinical application. Our lab pioneered cytokine-induced memory-like (ML) NK cells that are generated after brief activation with IL-12, IL-15, and IL-18. This overcomes many of the shortcomings of conventional NK cells as a cellular therapy. ML NK cells exhibited enhanced functionality, cytotoxicity, and persistence in a phase I clinical trial for acute myeloid leukemia (AML), with many patients achieving complete remissions from this novel intervention. Despite the translational advancement, there is little known about the underlying mechanisms of ML programming in NK cells. Clarifying the molecular programs that drive the ML phenotype will have broad implications for optimizing NK cells as a cellular-based therapy for hematological malignancies.
