In the last years, natural killer (NK) cell-based immunotherapy has emerged as a promising therapeutic approach for solid tumors and hematological malignancies. Challenges in CAR NK cell therapy in solid tumors. With the ongoing effort to improve the treatment response and new methods of generating more feasible clinical scales of NK cells, emerging clinical trials are being designed to evaluate these new modalities and to expand their indications. Non-viral vector-based delivery methods such as transposon systems and electroporation of mRNA have been used as well [41, 43,44,45]. North J, et al. A chimeric receptor with NKG2D specificity enhances natural killer cell activation and killing of tumor cells. 2000;356(9244):17959. 2023 BioMed Central Ltd unless otherwise stated. A novel source of NK cells has emerged to circumvent many of the challenges associated with NK cell therapy. The expanded human NK cells showed potent ADCC activities in vitro and superior tumor control in a mouse xenograft model of ovarian cancer when combined with Herceptin, an anti-HER2 antibody [87]. NK cell dysfunction via altered activating receptor expression or tumor downregulation of NK cell receptor ligands is a common method of tumor immune escape. For example, the absence of NKG2D and other NCR ligands on leukemic blasts allows them to escape NK cell surveillance [86, 87]. The NKG2C+NK cells can be found in the circulation of HCMV-seropositive individuals [22]. Cytotherapy. Stem Cells Transl Med. Lee HR, et al. Bryceson YT, et al. Google Scholar. TUMORS.

Despite decades of work, the ontogeny of NK cells in humans is still not fully elucidated. Sci Rep. 2015;5:11483. 2017;9(6):1796812. This successful immunotherapy has led to a more complete view of cancer that now considers not only the cancer cells to be targeted and destroyed but also the immune environment of the cancer cells. As an alternative to CAR-T cell therapy, CAR-NK cell therapy not only circumvents these challenges but also presents additional major advantages: (i) the ability to use unlimited allogeneic NK source without concern of GVHD [6, 31, 32]; (ii) the potential to generate off-shelf product with NK cell line or iPSC-NK [37,38,39,40,41]; (iii) relatively shortened production time; iv) recognition and killing tumor cells through NK cell native receptors independent of the CAR engineering [42], less likely allowing disease escape through downregulation of the CAR antigens as shown with CAR-T cell therapy [37].

Curr Opin Immunol. Conceptually, iPSC-NK can provide a homogenously differentiated NK cell population that can be expanded to clinical scale as an off-the-shelf supply, overcoming the limitation of the NK-92 cell line. Such ability to alter the course of differentiation opens a possibility to pursue resident or organ-specific phenotypes of NK cells. Clinical application of CAR-NK cell therapy in solid tumors.

Overall, these results indicate that NK cells can invade some solid tumors. When NK cells infiltrate solid tumors, high numbers of NK cells may be associated with better survival. However, in most cases, anti-tumor properties of NK cells are attenuated at the tumor bed.

In response to the mounting data on this emerging therapy, the present paper provides a thorough review of the technical issues, molecular background and current preclinical and clinical data associated with CAR-NK cell applications in cancer treatment. Source and clinical-scale expansion of NK cells with preserved cytotoxic activity are the major challenges for developing clinical-scale NK cell-based therapy. A wide range of tumor antigens have been targeted by CAR-NK cells in pre-clinical studies for hematological malignancies and solid tumors [38, 39, 41,42,43,44,45,46,47,48,49,50,51,52,53,54,55,56,57,58,59,60,61,62,63,64,65,66,67,68,69,70,71,72,73,74,75,76].
