Due to their innate ability to eliminate tumor cells, NK cell-based immunotherapies against cancer have been investigated for decades. Methods Mol Biol. One study showed that overnight co-incubation with a leukemia cell line CTV-1 or its lysate without cytokines was sufficient to prime potent NK cells in vitro cytotoxicity against otherwise NK-insensitive tumor cells but not normal hemopoietic cells [88]. Although CAR-NK cells hold great promise as a future off-the-shelf drug, there are NK cell-specific challenges, such as potential loss of viability and/or activity with freezethaw process and lack of in vivo persistence. Good manufacturing practice-compliant cell sorting and large-scale expansion of single KIR-positive alloreactive human natural killer cells for multiple infusions to leukemia patients. The BiKEs or TrikEs are composed of two or three linked single-chain antibody variable fragments of different antigen specificities [79]. The expansion of NK cells using IL-2 alone is relatively modest and typically results in only several cell divisions in medium containing 1000 U/mL of IL-2 [100]. Mu YX, et al. Br J Haematol. Blood.
