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. Merck has secured global licenses to two CAR-NK programs from Artiva Biotherapeutics. 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. 2015;23(2):3308. Human NK cells expanded with IL-15 in the presence GSK3 inhibition had increased expression of the NK cell maturation marker CD57 and transcription factors associated with late-stage NK cell maturation including T-bet, ZEB2, and BLIMP-1 as compared to those expanded with IL-15 alone [87].

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. Distinctly different from T cell receptors, NK cell receptors are germline-encoded and hard-wired receptors without a requirement for V(D)J recombination. 2018;32(2):52031. 2018; 23(2): 181192. 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. Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. Article Methods Mol Biol. This property, which is unique among immune cells, and their capacity to enhance antibody and T cell responses support a role for NK cells as anticancer agents. Granzin M, et al. WebCancer immunotherapy has achieved great success in the past few years. The combination of IL-2/IL-15/IL-21 can support up to eightfold expansion of NK cells [121]. NK cells are mounted with a repertoire of inhibitory and activating surface receptors (Table 1) [25,26,27,28,29]. Knorr DA, et al. J Xu Y, et al. Here, we review advances in current approaches to optimizing the NK cell antitumor response including combination with other immunotherapies, cytokines, checkpoint inhibition, and engineering NK cells with chimeric antigen receptors (CARs) for the treatment of pediatric solid tumors. Sci Rep. 2017;7(1):11075. Phillips JH, Lanier LL. Improved killing of ovarian cancer stem cells by combining a novel chimeric antigen receptor-based immunotherapy and chemotherapy. Beyond directing CAR-NK cytotoxicity against tumor cells by targeting tumor antigens, it has been proposed that CAR-NK cells can be used to eliminate immunosuppressive immune cells in the tumor microenvironment that include myeloid-derived suppressor cells (MDSCs) and M2 tumor-associated macrophages (TAMs) [77, 78]. 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. This TriKE design (GTB-3550) is currently in clinical trial for treating high-risk hematological malignancies (NCT03214666). However, the dose of NK cells being used for therapy is limited.

Fujisaki H, et al. The conventional linear model suggests that mature NK cells arise from common lymphoid progenitors (CLPs) by progressing through a linear continuum [24]. Miller et al. Journal of Hematology & Oncology For instance, 21-day NK culture of placenta-isolated NKs yields an average of 1.2109 NK cells with around 80% viability [106] and 1.591010 NK cells with an average purity of 92.37% from UCB [107]. 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]. Targeted drugs are the preferred recommendations for the systemic treatment of hepatocellular carcinoma. Over 100-fold expansion was achieved with Wilms tumor HFWT [134] and immortalized T lymphocyte Jurkat cell lines [135]. Effects of CSF1R-targeted chimeric antigen receptor-modified NK92MI & T cells on tumor-associated macrophages. Immunotherapy. 2012;14(7):83040. In many studies, IL-2 or IL-15 is supplemented during ex vivo expansion of NK cells and sometimes after NK cell infusion as well [5]. 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. Leukemia. This method resulted in a 1,560-fold expansion of NK cells with a purity of 92.37% after 21days of ex vivo culture[107]. NK cells are also potent producers of chemokines and cytokines such as interferon gamma (IFN-) and tumor necrosis factor alpha (TNF-) and thereby are essential in modulating adaptive immune responses. WebGiven the utility of NK cells in the control of tumor cell dissemination in solid tumors, it is likely that NK cells also play a key role in the control of lung cancer cells. Nat Rev Immunol. Front Med (Lausanne). NKG2D-deficient mice are defective in tumor surveillance in models of spontaneous malignancy. 2019;10:909. 2019;14(3):e0212455. However, CAR-T therapy has two major challenges: (i) requirement of a substantiate length of time to generate a therapeutic dose of autologous CAR-T cells which limits its feasibility to treat patients with rapidly progressing diseases; (ii) difficulty to obtain sufficient number of autologous T cells for CAR-T cell generation from heavily pre-treated and often lymphopenic cancer patients [37].

The success has encouraged many ongoing clinical investigations of NK cell-based cancer therapy alone or in combination with other regimes. Cytokine-mediated activation is frequently employed and currently under extensive investigation. Blood. Hepatocellular carcinoma (HCC) is a high-incidence malignant tumor worldwide and lacks effective treatment options. It was proposed that the cytokine pre-activated NK cells were memory-like with an enhanced response to cytokine or activating receptor re-stimulation weeks or months after the initial pre-activation [84]. Mol Immunol. Liu E, et al. 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. In treatments of solid tumors, adoptive transfer of ex vivo expanded natural killer (NK) cells has dawned as a new paradigm. Koehl U, et al. They showed that infusion of NK cells from HLA-haploidentical donors combined with subcutaneous IL-2 administration after a pre-conditioning regimen of high-dose cyclophosphamide and fludarabine resulted in successful in vivo expansion of donor NK cells and the induction of complete remission in 5 out of 19 patients with poor-prognosis acute myeloid leukemia (AML) [5]. MUC1-specific CAR-pNK therapy presented good safety profile and preliminary efficacy in preventing both tumor relapses and graft versus host disease [151].

Two biotechs aim to broaden the reach of cancer immunotherapy by applying gene editing tools to an emerging form of cell therapy through a wide-ranging Block copolymer-boron cluster conjugate for effective boron neutron capture therapy of solid tumors. 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]. 2018;6(1):136. CAR-NK cell therapy is a novel immunotherapy strategy by utilizing genetically-engineered NK cells to target specific cancer, which can be both liquid and 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].

In mouse, the lack of CD3 and the presence of NK1.1 are canonical criterion for distinguishing NK cells. It is believed that membrane-bound interleukins are able to stimulate the expansion of NK cells more effectively than the soluble form. Two CD19-targeting CAR-T products were approved by the FDA for treatment of B cell lymphomas and acute lymphoblastic leukemia (ALL).

Recent studies revealed that subset of mature NK cells can elicit long-lived adaptive-like nature in the specific context of CMV infection [21]. Natural killer (NK) cells can swiftly kill multiple adjacent cells if these show surface markers associated with oncogenic transformation. Emerging insights into natural killer cells in human peripheral tissues. 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]. The Ruggeri group showed that KIR-mismatched alloreactive donor NK cells protected bone marrow-transplanted AML patients from AML relapse while sparing graft versus host diseases (GVHD) [31, 32]. The NKG2D-2B4 containing CAR-NK had elevated Syk and Erk1/2 phosphorylation [42]. On the one hand, it was shown to enhance interferon gamma (IFN-) production, cytotoxic functions, and antibody-dependent cellular cytotoxicity(ADCC) responses [117]. 2016;5(4):e1115178.
