Despite promising results shown in hematologic tumors, immunotherapies for the treatment of solid tumors have mostly failed so far. Typically, a dose of UCB or placenta donor can be expended to an amount sufficient for one adoptive transfer procedure. Natural killer (NK) cells are an essential part of tumor immunosurveillance, evidenced by higher cancer susceptibility and metastasis in association with diminished NK activity in mouse models and clinical studies [1,2,3]. Natural killer (NK) cells inhibit systemic metastasis of glioblastoma cells and have therapeutic effects against glioblastomas in the brain. 2016;16(2):11223. Hemolytic anemia due to passenger lymphocyte syndrome in solid malignancy patients treated with allogeneic natural killer cell products. Biol Blood Marrow Transpl. As the activation and expansion methods are improving, it is becoming possible to prepare increasingly higher dosages of NK cells for adoptive transfer from a single-donor phlebotomy. WebArtivas NK cells engineered to express chimeric antigen receptors, or CARs, have the potential to enhance the targeting and activity of the NK cells against either hematologic NK cell infiltration ErbB2/HER2-specific NK cells for targeted therapy of glioblastoma.

Both UCB and placenta-derived cells contain some proportion of NK cell progenitors that have the capacity to differentiate into NK cells during maturation and expansion stages. 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].

Clinical-grade generation of active NK cells from cord blood hematopoietic progenitor cells for immunotherapy using a closed-system culture process. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. Conventional NK cells are short-lived innate lymphocytes that lack antigen specificity. Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. J The signaling domains of CAR-NK cells are very similar to those in CAR-T cells, typically composed of the fusion of CD3 with one or two TCR co-stimulatory molecule (s), such as CD28, 4-1BB, 2B4, DNAM1, and NKG2D. Ruggeri L, et al. The relative proportion of CD56bright and CD56dim NK cells in tissues can be very different from that observed in the peripheral blood [17]. Specificity and distribution according to genotype. Shiozawa M, et al. The NKG2D-2B4 containing CAR-NK had elevated Syk and Erk1/2 phosphorylation [42]. The differences also arise from activation approaches, such as the choice of interleukins, their combinations, type of feeder cells, and some other factors [95,96,97]. Masuyama J, et al. Three out of 12 patients had durable complete remissions [89], providing evidence for further clinical evaluation of this approach. Cancer Immunol Res. Szmania S, et al. All authors declare no conflict of interest. Cytokines, such as IL15, have been incorporated into killer engagers to further enhance NK cell functions [80].

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.

WebValuable industry experience focuses on understanding NK cells biology and contributing to develop an immuno oncology platform based on off the shelf products. For example, a subset of IL-22 secreting human ILC3s is CD56+NKp46+CD3 [14]. There are also many ongoing clinical trials to evaluate the safety and efficacy of tumor-targeting CAR-NK cells, including using HER2-specific CAR-NK cell to treat advanced or metastatic HER2-expressing solid tumors (NCT04319757), ROBO1-specific CAR-NK cell to treat a broad spectrum of solid tumors (NCT03940820), and MUC1-specific CAR-pNK to treat patients with MUC1-positive relapsed or refractory solid tumor (NCT02839954). 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. 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]. Cytotherapy. Terms and Conditions, Cite this article.

The current source and characteristics of NK cells for immunotherapies, expansion, and activation approaches are given in Tables 3 and 4. 2009;69(9):40107. OKT3, an anti-CD3 mAb, has been commonly added to the irradiated autologous PBMC feeder, which can promote the expansion of NK cells up to over 1000-fold [4, 142,143,144]. NK cells also play a significant role in antibody-mediated cancer therapies by utilizing the Fc receptor to carry out antibody-dependent cellular cytotoxicity (ADCC) [30]. Cancer-associated fibroblast-secreted CXCL16 attracts monocytes to promote stroma activation in triple-negative breast cancers. They patrol our bodies for abnormal cells like cancer and destroy them. A first-in-human clinical trial of CAR NK-92 cells in 3 patients with relapsed or refractory AML showed that CAR NK-92 can be infused at doses up to 5 billion cells per patient without causing significant adverse effects [149]. 2012;3:319.

Exposure of NK to unmodified NK cell-sensitive leukemia cells (K562) stimulates expansion and short-term proliferation [133]. With the subcutaneous hypopharyngeal tumor xenograft model, it was shown that CXCR1-expressing CAR-NK cells had enhanced tumor infiltration and tumor control as compared to control CAR-NK cells [54]. The BiKEs or TrikEs are composed of two or three linked single-chain antibody variable fragments of different antigen specificities [79]. Natural killer cells: definition of a cell type rather than a function. Glyostems lead candidate NK cell therapy is currently being tested in a phase 1/2a trial for the treatment of the blood cancer acute myeloid leukemia. 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. 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. Emerging insights into natural killer cells in human peripheral tissues. 2015;220(7):87688. Front Immunol. Additional markers such as lack of c-kit can be used to distinguish human NK (c-kit-) from ILC3s (c-kit+) [14]. 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].
