Front Immunol. WebThis page lists cancer drugs approved by the Food and Drug Administration (FDA) for the treatment of solid tumors based on their genetic and molecular features and not on PLoS ONE. It is believed that membrane-bound interleukins are able to stimulate the expansion of NK cells more effectively than the soluble form. Blood. NK cell represents a specialized immune effector cell population equipped with fast-acting and potent anti-tumor capacity. When expanded it provides a list of search options that will switch the search inputs to match the current selection. Hum Gene Ther Methods. Xu Y, et al. Cancer Immunol Res. Other methods may include transgene of suicide gene or expression of a fluorescent marker in the feeder cell. WebNK cell-mediated control of large solid tumors is usually not efficient, although tumors often express high amounts of activating ligands and low levels of inhibitory ligands, The advantage of adherent condition is that it provides defined environment for optimizing the differentiation. In this review, we provide our current understandings of NK cell biology, ongoing pre-clinical and clinical development of NK cell-based therapies and discuss the progress, challenges, and future perspectives. Sakamoto Despite decades of work, the ontogeny of NK cells in humans is still not fully elucidated. 2016;1441:34761. 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]. 2B4 costimulatory domain enhancing cytotoxic ability of anti-CD5 chimeric antigen receptor engineered natural killer cells against T cell malignancies. 1981;41(11 Pt 1):44205. Due to their innate ability to eliminate tumor cells, NK cell-based immunotherapies against cancer have been investigated for decades. NK Cell-mediated antibody-dependent cellular cytotoxicity in cancer immunotherapy. Sci Rep. 2019;9(1):13288. Targeting immunosuppressive components in the TME to re-invigorate NK functions is also under investigation. 2017;8:87. Dev Cell. 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. 2017;23(2):489502. 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. 2015;15:1011. NKG2D, an activating NK cell receptor, can bind to eight different stress-induced ligands that are naturally expressed on 80% of hematological and solid cancer 2015;13(3):46471. 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. WebAB-201 is our clinical-stage CAR-NK cell therapy candidate targeting HER2-positive solid tumors. Blood. Although CAR-NK cells hold great promise as a future off-the-shelf drug, there are NK cell-specific challenges, such as potential loss of viability and/or activity with freezethaw process and lack of in vivo persistence. Sizhe Liu, Vasiliy Galat, Yekaterina Galat, Yoo Kyung Annie Lee, Derek Wainwright, and Jennifer Wu wrote and reviewed the manuscript. The NKG2C+NK cells can be found in the circulation of HCMV-seropositive individuals [22]. Tang X, et al. Zhang Q, et al. Eur J Cancer. Cancer Res. 2005;42(4):50110. IL15 Trispecific Killer Engagers (TriKE) Make natural killer cells specific to CD33+ targets while also inducing persistence, in vivo expansion, and enhanced function. Characterization of the maturation stage of NK cells demonstrated that RLI favored accumulation of CD11b⁺ CD27^high KLRG1⁺ 2004;24(3b):186171. The approach of using the modified NK cell line CAR-NK92, which can be easily expanded to large dose, has been in clinical trial. J Exp Med. Parodi M, et al. Biol Blood Marrow Transpl. However, since 1964, only Cordyceps 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. Engineering NK cells modified with an EGFRvIII-specific chimeric antigen receptor to overexpress CXCR4 improves immunotherapy of CXCL12/SDF-1alpha-secreting glioblastoma. On the one hand, it was shown to enhance interferon gamma (IFN-) production, cytotoxic functions, and antibody-dependent cellular cytotoxicity(ADCC) responses [117]. Effective against blood cancers, natural killer cells also may be effective against solid tumors. 2006;66(1):51726. Miller et al. Join us for this live, CME-certified symposium featuring an expert discussion of TROP2- and HER3-targeted antibody-drug conjugates and their current use in treating patients with solid tumors, including lung and breast cancers. Grimm, E.A., et al., Lymphokine-activated killer cell phenomenon. 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]. 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]. 1985; 161(6): 146482. Notably, certain tissues such as the mucosal barriers possess subsets of recently identified innate lymphoid cells (ILCs) that also share canonical markers of NK cells. developed an NK cell recruiting protein-conjugated antibody (NRPbody) containing a mesothelin-specific tumor targeting domain Meso-scFv and the chemokine CXCL16 linked by a furin cleavage sites [90]. New research by Fred Hutchinson Cancer Center molecular biologist Ami Yamamoto in the Cheung Lab, shows that a tumors necrotic core a mass of dying and dead cells previously thought to be inconsequential or perhaps even Handgretinger R, Lang P, Andre MC. With the new era of cancer immunotherapy, the use of Chimeric Antigen Receptor (CAR) T-cells has been applied with other possible approaches like NK (natural Mol Immunol. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. 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. Eur J Immunol. Ex vivo expansion of highly cytotoxic human NK cells by cocultivation with irradiated tumor cells for adoptive immunotherapy. Wang et al. But what it does in the realm of cancer spread is creepier still. 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]. 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]. Sci Rep. 2019;9(1):14916. 2009;373(9674):155061. CAR-NK cell therapy has proven to kill hematological and solid tumor cells in preclinical and clinical trials, demonstrating its potential as an off-the-shelf product with Currently, strategies vary depending on the clinical setting and source of cells. Cao B, et al. Google Scholar. Lancet. 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 NK cells with KIR2DS2 immunogenotype have a functional activation advantage to efficiently kill glioblastoma and prolong animal survival. 2012;61(9):145161.

Among these TCR cell co-stimulatory molecules, 4-1BB, DNAM1, 2B4, and NKG2D were also expressed by NK cells as native activating receptors. BMC Immunol. Skeate R, et al. observed in CAR NK cell therapy in liquid tumors have not yet been seen in Recently, the differentiation method was also established in adherent monolayer cultures [108]. This method has achieved over 15% of CD34+ hematopoietic progenitors compared to other methods producing only up to 4% of CD34+. Typically, the differentiation was induced in embryoid bodies or by OP9 mouse stroma co-culture [111]. 2014;20(4):46373. Phase I study of cord blood-derived natural killer cells combined with autologous stem cell transplantation in multiple myeloma. 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]. Clin Cancer Res.

Koehl U, et al. Table 6 summarizes updated clinical trials of NK cell-based therapy for all solid tumors. Expression of chimeric receptor CD4zeta by natural killer cells derived from human pluripotent stem cells improves in vitro activity but does not enhance suppression of HIV infection in vivo. Use of CAR-transduced natural killer cells in CD19-positive lymphoid tumors. Liu E, et al. 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]. NKp44-NKp44 ligand interactions in the regulation of natural killer cells and other innate lymphoid cells in humans. J Immunol. 2016;7(19):2776477. [2017][J Control Release][10.1016j.jconrel.2017.03. 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]. Google Scholar. Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. Front Immunol. 2014;28(4):91727. NK cells were identified over four decades ago as lymphocytes with innate ability to lyse tumor cells without the need for prior sensitization [8,9,10]. It is currently believed that the success of adoptive transfer requires the creation of a lymphopenic environment to provide a niche for donor cells to survive and proliferate. 2016;22(3):596608. 2011;6(6):e20740. 1986;137(9):27359. A good manufacturing practice method to ex vivo expand natural killer cells for clinical use. Wang W, et al. This strategy of GSK3 inhibition was used to generate FATE-NK100, which is being evaluated in an ongoing phase 1 clinical trial either as a monotherapy or in combination with monoclonal antibodies in patients with advanced solid tumors (NCT03319459). Cytokine-free directed differentiation of human pluripotent stem cells efficiently produces hemogenic endothelium with lymphoid potential. Despite promising results shown in hematologic tumors, immunotherapies for the treatment of solid tumors have mostly failed so far. 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. Lopez-Soto A, et al. Google Scholar. Kim EK, et al. WebCancer immunotherapy has achieved great success in the past few years. 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. WebChimeric antigen receptor T cells therapy (CAR-T therapy) is a class of ACT therapy. Markers and function of human NK cells in normal and pathological conditions. Distinctly different from T cell receptors, NK cell receptors are germline-encoded and hard-wired receptors without a requirement for V(D)J recombination. Mesothelin is a tumor differentiation antigen that is highly overexpressed in several human cancers including malignant mesothelioma, pancreatic, ovarian, and lung adenocarcinoma [91].

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. Liu B, et al. Huang Y, et al. Hepatocellular carcinoma (HCC) is a high-incidence malignant tumor worldwide and lacks effective treatment options. 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]. 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. Perform PBMCs apheresis from the patient and isolate NK cells, transfect the NK cells with Claudin6 targeting CAR, amplify the number of transfected NK cells as Interleukin (IL)-2 (IL-2) is one of the first and most important cytokines used for NK maintenance and is integral for NK cell survival.
