The donor-derived NK cells have certain limitations mainly because of their variability in functional competence and expansion potential. There are numerous ongoing clinical trials exploring the safety and efficacy of NK-based therapy in combination with other modalities. Moreover, the CAR-NK cells secrete pro-inflammatory cytokines and chemokines which may improve the infiltration and functions of subsequently infused CAR-T cells in the mouse model [77].

Most recent studies showed that ex vivostimulation of human NK cells with the combination of IL-15/IL-18/IL-27 can achieve 17-fold expansion [122], and that the combination of IL-2 with IL-18 can achieve approximately 500-fold expansion over two-week period [123].

In allogeneic transfer settings, the concept of KIR and HLA mismatches between donor and recipient was the original strategy aimed at enhancing the activation of donor NK cells to eradicate patients tumor cells. T cells equipped with CARs have been shown to provide clinical benefit for patients with select liquid cancers. It was suggested that induced expression of CD69 on NK cells is important for the cytotoxicity of the CTV-1 tumor cell-activated NK [88]. However, there are many challenges to overcome, such as difficulty to meet clinical-grade ex vivo expansion, limited in vivo persistence, limited infiltration to solid tumors, and tumor editing to evade NK cell activity. The other important feature of iPSC-NK cell technology is the ability to manipulate the differentiation strategy, thus shaping the phenotype and functionality of the resulting product. 2016;16(2):11223. J Cell Mol Med. 2012;3:319. Phase I clinical trial of autologous NK cell therapy using novel expansion method in patients with advanced digestive cancer. Methods Mol Biol. Similar to CAR-T cells, CAR-NK cells are genetically modified to express CARs that recognize a specific antigen uniquely expressed or overexpressed by target cells. The safety and efficacy of allogeneic or autologous donor-derived NK cell-based therapy for treating hematological malignancies, such as AML, have been well established [5, 29, 148].

Crucially, tumor antigen-expressing CAR-NK cell therapy increases anti-tumor activities. Thus, NK cell transfer presents an effective method of fighting cancer. volume14, Articlenumber:7 (2021) Herein we highlight current evaluations for hematological malignancies and solid tumors.

In pre-clinical studies, various BiKEs and TriKEs have been designed to target a number of tumor antigens: CD19, CD20, and CD33 for hematological cancers, HER2, EGFR, and EpCAM for solid tumors [79]. It remains to be determined how NRPbody will interact with a more complex and realistic immune contexture in the TME which consists of more than NK cells, as CXCL16 was shown in other tumor models to correlate with the infiltration of monocytes and M2-macrophages as well [92, 93].

However, NK cell therapy directed against solid tumors is still in early development. With the new tools of iPSC-NK and genetic engineering approach as well as new understandings of NK cell biology, it is the time to re-explore the therapeutic potentials of NK cells. While the majority of investigation of ex vivo NK priming strategies rely on one or more cytokines, some studies indicate that cytokine supplement is not as critical for NK cell priming.

Immunotherapy is a breakthrough in the systemic treatment of malignant tumors, including HCC. Based on characterization of NK cells in the peripheral blood, human NK cells are conventionally sub-divided into two major subsets: CD56brightCD16dim/ and CD56dimCD16+, with the former classically believed to be less mature and a potent cytokine producer and the latter more mature and the most cytotoxic [17, 19].

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]. 2006;66(1):51726. It was hypothesized that once bound to mesothelin-overexpressing tumor cells, furin-mediated cleavage would release CXCL16 from the NRPbody and thereby recruit NK cells to the tumor sites [90]. 2015;17(5):61320.

Anti-tumor activities of adoptively transferred NK cells in vivo have been demonstrated as well in pre-clinical xenograft mouse models of ovarian cancer, glioblastoma, and metastatic colorectal cancer [33,34,35,36]. Distinctly different from T cell receptors, NK cell receptors are germline-encoded and hard-wired receptors without a requirement for V(D)J recombination.
