In pre-clinical studies, various BiKEs and TriKEs have been designed to target a number of tumor antigens: CD19, CD20, and CD33 for hematological cancers, HER2, EGFR, and EpCAM for solid tumors [79]. 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. 2016;127(26):33419. NK cells in the tumor microenvironment Conventional roles of NK cells in immunity Detection of aberrant cells by NK cells is determined by the intergradation of Human iPSC-derived natural killer cells engineered with chimeric antigen receptors enhance anti-tumor activity. To circumvent these challenges, Bi- and tri-specific killer engagers, BiKEs and TriKEs, are in development as a complemental approach. 2B4 costimulatory domain enhancing cytotoxic ability of anti-CD5 chimeric antigen receptor engineered natural killer cells against T cell malignancies. Upon activation, NK cells release cytotoxic granules containing perforin and granzymes to directly lyse tumor cells, in a similar fashion to activated cytotoxic T cells. Sahm C, Schonfeld K, Wels WS. The NKG2D-2B4 containing CAR-NK had elevated Syk and Erk1/2 phosphorylation [42]. Skeate R, et al. The other important feature of iPSC-NK cell technology is the ability to manipulate the differentiation strategy, thus shaping the phenotype and functionality of the resulting product.

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 2019;10:909. Cytokines, such as IL15, have been incorporated into killer engagers to further enhance NK cell functions [80]. In the clinical setting, each batch requires validation, which results in additional lag time before a patient receives infusion. 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]. Dege C, et al. Torelli GF, et al. 2016; 8(357): p. 357ra123. The integration and balance of the activating and inhibitory signals from the ligand/receptor interactions dictates the status of NK cell activation. Herein, we will provide an updated overview of the emerging endeavors for developing NK cell-based cancer immunotherapy from pre-clinical conceptual development, clinical grade expansion, and ongoing clinical development. Phase I/II clinical trials are ongoing to evaluate the safety and efficacy of NK cell combined with nimotuzumab to treat late-stage malignancies (NCT03554889) and of NK cell infusion on patients with advanced malignant tumors following multi-line therapies (NCT03619954). The BiKEs or TrikEs are composed of two or three linked single-chain antibody variable fragments of different antigen specificities [79]. The mechanism of CTV-1-mediated NK priming is unclear.

Ex vivo-expanded NK cells from blood and ascites of ovarian cancer patients are cytotoxic against autologous primary ovarian cancer cells. WebPhysiological barriers and immunosuppressive microenvironments of solid tumors present considerable hurdles to Chimeric antigen receptor T (CAR-T) cell therapy. Mesothelin is a tumor differentiation antigen that is highly overexpressed in several human cancers including malignant mesothelioma, pancreatic, ovarian, and lung adenocarcinoma [91]. Ex vivo-expanded natural killer cells demonstrate robust proliferation in vivo in high-risk relapsed multiple myeloma patients. Stem Cells. Yang Y, et al. NKG2D-deficient mice are defective in tumor surveillance in models of spontaneous malignancy. First-in-man clinical trial of CAR NK-92 cells: safety test of CD33-CAR NK-92 cells in patients with relapsed and refractory acute myeloid leukemia. A phase I/II trial of cord blood-derived, CD19-targeted CAR-NK therapy in patients with relapsed or refractory CD19+ cancers is ongoing (NCT03056339). In the last 3 decades, NK cells have been utilized to harness 2016;18(5):65363. 2016;5(9):e1219007. Some investigations have sought to enhance NK migration toward the tumor by genetically modifying NK cells to overexpress chemokine receptors [54, 59, 94]. All authors read and approved the final manuscript. For instance, healthy cells express no or minimal level of ligands for NK cell activating receptors, but express high levels of the major histocompatibility complex class I molecules (MHC I), also known as human leukocyte antigen (HLA), that ligates to the killer immunoglobulin-like (KIR) family inhibitory receptors on NK cells to protect them from NK attack [29]. This approval was based on clinical study demonstrating that oNKord improves survival in year 1 of 80% vs. 35% in the control arm. With the new tools of iPSC-NK and genetic engineering approach as well as new understandings of NK cell biology, it is the time to re-explore the therapeutic potentials of NK cells. 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]. GSK3 inhibition drives maturation of NK cells and enhances their antitumor activity. 2002;295(5562):2097100. Combination therapy with EpCAM-CAR-NK-92 cells and regorafenib against human colorectal cancer models. [2017][J Control Release][10.1016j.jconrel.2017.03. J 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]. 2017;18(9):100415. Br J Cancer. Nat Rev Immunol. Using allogeneic NKs for adoptive transfer without expansion after a short overnight incubation with cytokines was shown to be sufficient to activate NK cells and enhance their cell cytotoxicity against tumor targets [86]. Front Immunol. J Cell Mol Med. Miller 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]. 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. Membrane-bound IL-21 promotes sustained ex vivo proliferation of human natural killer cells. NK Cells of the Lung The release criteria should be developed with unique signature to distinguish the feeder cells from expanded NK cells to ensure no feeder cell contamination. Cytokines in clinical cancer immunotherapy. Multifunctional natural killer cell engagers targeting NKp46 trigger protective tumor immunity. Biol Blood Marrow Transpl. 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]. WebHappy New Year to you! 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].

Ex vivo-expanded highly purified natural killer cells in combination with temozolomide induce antitumor effects in human glioblastoma cells in vitro. An antibody designed to improve adoptive NK-cell therapy inhibits pancreatic cancer progression in a murine model. However, NK cell therapy directed against solid tumors is still in early development. 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]. WebAbstract Background AB-101 is a non-engineered, allogeneic, off-the-shelf, cryopreserved cord blood-derived natural killer (NK)-cell therapy in development as a cancer 2006;66(1):51726. Adoptive transfer of autologous natural killer cells leads to high levels of circulating natural killer cells but does not mediate tumor regression. Instead, a combination of transcription factors, including T-bet, Eomes, E4BP4, Id2, and BLIMP, was identified to instruct NK development and maturation [23]. Phase I study of cord blood-derived natural killer cells combined with autologous stem cell transplantation in multiple myeloma. The donor-derived NK cells have certain limitations mainly because of their variability in functional competence and expansion potential. It was shown that of CD3-depleted peripheral blood mononuclear cells (PBMC) with IL-21 and IL-15 for 1320days resulted in 3.7-fold expansion of NK cells with clinical activity in delaying leukemia progression [120]. Ascorbic acid promotes proliferation of natural killer cell populations in culture systems applicable for natural killer cell therapy. Distinctly different from T cell receptors, NK cell receptors are germline-encoded and hard-wired receptors without a requirement for V(D)J recombination. NK CELL-BASED THERAPY IN SOLID.
