To date, more than 350 Cordyceps-related species have been found worldwide based on fungus and/or insect host. The anti-CD3 mAb presumably activates T cells in feeder to secret cytokines which subsequently create a milieu favorable for NK cell expansion [145]. Phase I clinical trial of autologous NK cell therapy using novel expansion method in patients with advanced digestive cancer. Nat Rev Immunol. Clinical-grade generation of active NK cells from cord blood hematopoietic progenitor cells for immunotherapy using a closed-system culture process. A novel chimeric PD1-NKG2D-41BB receptor enhances antitumor activity of NK92 cells against human lung cancer H1299 cells by triggering pyroptosis. In humans, NK cells are traditionally identified by the absence of CD3 and the presence of CD56 on their surface as characterized by flow cytometry. You F, et al. The purification of NK cells is typically achieved by magnetic depletion of CD3-expressing cells and subsequent enrichment for CD56-expressing cells [100] or by fluorescence-activated cell sorting [101]. The deal gives Merck control of two off-the-shelf solid tumor cell Mol Ther.

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]. The linear model proposes that CD56 marks a transition from immature into a more mature status and that immature CD56bright NK cells further differentiate into mature CD56dim populations in human [19, 24]. 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. Article 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]. 2015;17(11):158293. An even greater expansion of NK cells, of over 30,000-fold in a period of 3weeks, was achieved with K562 membrane-bound IL-21 and 4-1BB ligand [127,128,129,130]. Clin Cancer Res.

One approach to address the safety concern is the use of lysed cell product. However, NK cell therapy directed against solid tumors is still in early development. 2014;20(4):46373. The integration and balance of the activating and inhibitory signals from the ligand/receptor interactions dictates the status of NK cell activation. Different from events required for T cell activation, NK cell activation is governed by the interaction of NK receptors with target cells, independent of antigen processing and presentation. Webgeneration NK cell therapies. Childs RW, Berg M. Bringing natural killer cells to the clinic: ex vivo manipulation. Oncoimmunology. 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]. [2017][J Control Release][10.1016j.jconrel.2017.03. Nat Rev Immunol. reported an approximately 1500-fold expansion of NK cells after PBMC stimulation with a combination of anti-CD3 and anti-CD56 mAbs [146]. Chu J, et al. Necrotic core even the name sounds creepy. For example, there is an ongoing phase 2 clinical trial to evaluate the safety and efficacy of human HLA-haploidentical hematopoieticcelltransplantation (HCT) followed by an early, post-transplant infusion of donor NKcells (NCT02100891). Exploring the NK cell platform for cancer immunotherapy. Choi I, et al. Moreover, highly cytotoxic NK cells derived using such method are capable of producing endogenous cytokines that improve their survival, proliferation, and function [132]. However, a more complex scenario has recently emerged. Cancer Sci. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. In most pre-clinical studies, lentiviral or retroviral-based transduction was used to achieve stable and sustained CAR expression in NK cells. Blood. 2013;13(2):1459. 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]. Membrane-bound IL-21 promotes sustained ex vivo proliferation of human natural killer cells. By using this website, you agree to our Some clinical efficacy has also been demonstrated for allogeneic as well as autologous NK cell therapy, either alone or in combination with conventional therapies. Crucially, tumor antigen-expressing CAR-NK cell therapy increases anti-tumor activities. Thus, NK cell transfer presents an effective method of fighting cancer. Adenosine impairs the anti-tumor functions of both T and NK cells [43]. Despite promising results shown in hematologic tumors, immunotherapies for the treatment of solid tumors have mostly failed so far. Targeting T-cell malignancies using anti-CD4 CAR NK-92 cells. 2006;107(1):15966. Clin Cancer Res. But cancer cells can make themselves invisible, making it much more difficult for NK cells to find them and do their job. 2012;7(1):e30264. Freshly isolated, activated, or in vitro expanded NK cell populations display phenotypic and functional differences. Although lethal irradiation of feeder cells before use is required, for safety concern, the residual contamination of feeder cells should be assessed. Markers and function of human NK cells in normal and pathological conditions. 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 Phillips JH, Lanier LL. Webwith a high chance of succeeding in solid cancer therapy. The trial is NK cells are found both in blood at levels of 5%-15% of circulating lymphocytes and in various lymphoid and non-lymphoid organs such as the spleen, lung, and liver [17, 18]. For instance, the enhancement of the Wnt signaling pathway with GSK3b inhibitor induces definitive hematopoiesis [112, 113] NK cells developed in such conditions had more pronounced inflammatory cytokine production phenotype, whereas Wnt independent NK subsets, similar to primary fetal NK cells, formed a bias for increased cytotoxicity [110]. 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. 2020;524(1):96102. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. Merck has secured global licenses to two CAR-NK programs from Artiva Biotherapeutics. Skeate R, et al. Challenges in CAR NK cell therapy in solid tumors.

J Transl Med. Innate lymphoid cells: a proposal for uniform nomenclature. Stimulating antibodies is typically used along with irradiated allogeneic PBMC to further promote NK activation and expansion. 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]. 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]. 2018;8(6):10839. However, NK92 is a transformed cell line that has limitations associated with its tumorigenic nature, and cytogenetic abnormalities, thus requiring irradiation for clinical use, which limits its life-time activity. Aiming to generate novel CAR-NK cell-based cancer therapeutics, the consideration of tumor-specific surface antigens and the costimulatory molecules is the 2008;28(4):57180. Bone marrow is considered to be the primary site of NK development. In mouse, NK and ILC1 are NK1.1+CD3 but can be further characterized by CD49a and Eomes expression. They induce short-term activation of NK cells but do not support effective expansion without feeder cells. PubMed Central 2015;13(3):46471. 2020;111(5):147890. The antigen recognition domain usually consists of a single-chain fragment (scFV) molecule derived from a monoclonal antibody, and nanobody-based constructs have been used in limited studies to date [72]. 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]. CD19-CAR engineered NK-92 cells are sufficient to overcome NK cell resistance in B-cell malignancies. Immunotherapy is a breakthrough in the systemic treatment of malignant tumors, including HCC. Lancet. IL-2 was used to induce lymphokine-activated killer (LAK) cells, a heterogeneous population of cells consisting primarily of NK, NKT, and T cell for autologous killer cell-based cancer therapy decades ago [115]. 2009;69(9):40107. Clinicaltrials.gov currently lists over 100 clinical trials of NK cell-based cancer immunotherapy. 2007;178(1):8594. 2013;2(4):27483. It is believed that membrane-bound interleukins are able to stimulate the expansion of NK cells more effectively than the soluble form. 2017;47(5):82033. Hepatocellular carcinoma (HCC) is a high-incidence malignant tumor worldwide and lacks effective treatment options. The exhausted T cells or NK cells in the tumor microenvironment exhibit imbalanced Lim SA, et al. Ishikawa E, et al. 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]. A study by Campana and coworkers has shown that stimulation of NK cells with gene-modified K562 expressing the NK-stimulatory molecules 4-1BB ligand and IL-15 induced a median 21.6-fold expansion during a 7-day culture period. Common gamma chain cytokines such as IL2, IL-7, and IL15 and their receptor components including CD122 and CD127 have been shown to play essential roles in NK development and homeostasis [19]. 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. 2018;24(8):15819.
