A more simplified NK cell expansion method has been used by combining group Astreptococcus and zoledronate with IL-2 to stimulate UCB-derived mononuclear cells. Chemical stimuli such as Concanavalin A(ConA) [138], Phytohemagglutinin (PHA), and ionomycin [139] were also used in combination with irradiated allogeneic PBMCs to facilitate the activation. Zhang Q, et al. Cancer Manag Res. To circumvent these challenges, Bi- and tri-specific killer engagers, BiKEs and TriKEs, are in development as a complemental approach. In addition to cytokine-only strategies, Cichocki and colleagues demonstrated that pharmacologic inhibition of GSK3 kinase with CHIR99021 drives late-stage maturation of ex vivo-expanded human peripheral blood NK cells and enhanced their anti-tumor effector functions both in vitro and in vivo [87]. NK cells stimulate recruitment of cDC1 into the tumor microenvironment promoting cancer immune control. Cite this article. Characterization of the maturation stage of NK cells demonstrated that RLI favored accumulation of CD11b+ CD27high KLRG1+ 2013;15(2):231-241.e1. In treatments of solid tumors, adoptive transfer of ex vivo expanded natural killer (NK) cells has dawned as a new paradigm. CD19-CAR engineered NK-92 cells are sufficient to overcome NK cell resistance in B-cell malignancies. In summary, NK cells are functional in tumor surveillance and can be manipulated by artificial activation techniques to present a highly effective anticancer tool against hematopoietic malignancies and, dependent on successful further rearming and mobilization, against solid tumors in the future. Table 5 summarizes the clinical trials of NK cell-based therapy for hematological malignancies to date. Autologous peripheral blood stem cell transplantation and adoptive immunotherapy with activated natural killer cells in the immediate posttransplant period. 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]. Schnalzger TE. further pioneered the use of NK cells in non-transplant settings. J Immunother. In order to avoid critical side effects, such as GVHD caused by alloreactive T cells [98] or a passenger lymphocyte syndrome caused by donor-derived B cells [99], purification is recommended for allogeneic NK cells before the expansion to restrict contaminating total T cells to less than 15105/Kg.

A chimeric receptor with NKG2D specificity enhances natural killer cell activation and killing of tumor cells. Multi-dose Treatment Cohorts Initiated in FT576 Phase 1 Study for Multiple Myeloma; Interim Knorr DA, et al. PubMed 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. Phase I study of cord blood-derived natural killer cells combined with autologous stem cell transplantation in multiple myeloma. CXCL16 positively correlated with M2-macrophage infiltration, enhanced angiogenesis, and poor prognosis in thyroid cancer. 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]. J Exp Med. All authors declare no conflict of interest. Despite the immunosuppressive environment of solid tumors, NK cell activity/infiltration has been correlated with improved prognoses in humans. 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]. While the CAR technology seeks to enhance NK cell functions by genetically directing their target specificity, there are active investigations on other strategies to effectively prime NK cells ex vivo or in vivo for optimal anti-tumor functions after their infusion.

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. However, the exhaustion of T cells or NK cells can lead to the failure of tumor control and limit the complete response and overall efficacy of cancer immunotherapy against solid tumors. NKG2D and its ligands in cancer. Chimeric antigen receptor (CAR) is an engineered synthetic receptor of CAR-T, which give T cells the ability to recognize tumor antigens in a human leukocyte antigen-independent (HLA-independent) manner and enables them to recognize more extensive target Current challenges WebPhysiological barriers and immunosuppressive microenvironments of solid tumors present considerable hurdles to Chimeric antigen receptor T (CAR-T) cell therapy.

Despite promising results shown in hematologic tumors, immunotherapies for the treatment of solid tumors have mostly failed so far. Luhm J, et al. This method was advantageous in that it did not require magnetic cell sorting, feeder cells, or multiple cytokines, potentially lowering the cost of production. Natural killer (NK) cell is a specialized immune effector cell type that plays a critical role in immune activation against abnormal cells.

Use of chimeric antigen receptor NK-92 cells to target mesothelin in ovarian cancer. 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].
