CD56 expression in breast cancer induces sensitivity to natural killer-mediated cytotoxicity by enhancing the formation of cytotoxic immunological synapse. Sci Rep 2019; 9:8756. [PMID: 31217484 PMCID: PMC6584531 DOI: 10.1038/s41598-019-45377-8] [Citation(s) in RCA: 16] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/23/2018] [Accepted: 05/28/2019] [Indexed: 02/07/2023] Open
Abstract
We examined the potential value of the natural killer (NK) cell line; NK-92, as immunotherapy tool for breast cancer (BC) treatment and searched for biomarker(s) of sensitivity to NK-92-mediated cytotoxicity. The cytotoxic activity of NK-92 cells towards one breast precancerous and nine BC cell lines was analyzed using calcein-AM and degranulation assays. The molecules associated with NK-92-responsiveness were determined by differential gene expression analysis using RNA-sequencing and validated by RT-PCR, immunostaining and flow cytometry. NK-target interactions and immunological synapse formation were assessed by fluorescence microscopy. Potential biomarker expression was determined by IHC in 99 patient-derived BC tissues and 10 normal mammary epithelial tissues. Most (8/9) BC cell lines were resistant while only one BC and the precancerous cell lines were effectively killed by NK-92 lymphocytes. NK-92-sensitive target cells specifically expressed CD56, which ectopic expression in CD56-negative BC cells induced their sensitivity to NK-92-mediated killing, suggesting that CD56 is not only a biomarker of responsiveness but actively regulates NK function. CD56 adhesion molecules which are also expressed on NK cells accumulate at the immunological synapse enhancing NK-target interactions, cytotoxic granzyme B transfer from NK-92 to CD56-expressing target cells and induction of caspase 3 activation in targets. Interestingly, CD56 expression was found to be reduced in breast tumor tissues (36%) with strong inter- and intratumoral heterogeneity in comparison to normal breast tissues (80%). CD56 is a potential predictive biomarker for BC responsiveness to NK-92-cell based immunotherapy and loss of CD56 expression might be a mechanism of escape from NK-immunity.

Abstract
Natural killer (NK) cells are increasingly considered as immunotherapeutic agents in particular in the fight against cancers. NK cell therapies are potentially broadly applicable and, different from their T cell counterparts, do not cause graft-versus-host disease. Efficacy and clinical in vitro or in vivo expansion of primary NK cells will however always remain variable due to individual differences of donors or patients. Long-term storage of clinical NK cell lots to allow repeated clinical applications remains an additional challenge. In contrast, the established and well-characterized cell line NK-92 can be easily and reproducibly expanded from a good manufacturing practice (GMP)-compliant cryopreserved master cell bank. Moreover, no cost-intensive cell purification methods are required. To date, NK-92 has been intensively studied. The cells displayed superior cytotoxicity against a number of tumor types tested, which was confirmed in preclinical mouse studies. Subsequent clinical testing demonstrated safety of NK-92 infusions even at high doses. Despite the phase I nature of the trials conducted so far, some efficacy was noted, particularly against lung tumors. Furthermore, to overcome tumor resistance and for specific targeting, NK-92 has been engineered to express a number of different chimeric antigen receptors (CARs), including targeting, for example, CD19 or CD20 (anti-B cell malignancies), CD38 (anti-myeloma) or human epidermal growth factor receptor 2 (HER2; ErbB2; anti-epithelial cancers). The concept of an NK cell line as an allogeneic cell therapeutic produced 'off-the-shelf' on demand holds great promise for the development of effective treatments.

Abstract
Cytokine-induced killer (CIK) cells, one of the feasible and effective methods of adoptive immunotherapy, have shown anti-leukemia activity in vivo and in vitro. But the strategy exhibits limited cytotoxic activity in clinical studies. In this study, CIK cells were transfected with an interleukin-3/Pseudomonas exotoxin gene (IL3PE38KDEL). RT-PCR and ELISA were used to verify the expression of IL3PE38KDEL in the transfected CIK cells. These cells released 1,186.7 ± 149.6 pg IL3PE38KDEL/10(4) cells over 48 h into the medium and the culture supernatant selectively killed IL3 receptor(IL3R)-positive HL60 cells, but not IL3R-negative K562 cells. Moreover, IL3PE38KDEL transfection did not influence phenotypes and cytokine production of CIK cells. Co-cultured with leukemia cells, IL3PE38KDEL transfected CIK cells showed enhanced cytotoxicity against IL3R-positive HL60 cells at all effector-to-target (E:T) ratios, but exerted a basal anti-leukemia activity against IL3R-negative K562 cells. Our findings demonstrate that IL3PE38KDEL gene transfection may be a novel strategy for improving anti-leukemia activity of CIK cells.

Abstract
OBJECTIVE To evaluate the immunomodulation of inducible co-stimulator (ICOS) in cytokine-induced killer (CIK) cells against cholangiocarcinoma. METHODS CIK cells were generated from normal peripheral blood mononuclear cells. Methyl thiazolyl tetrazolium assay was performed to assess proliferation of CIK-ICOS and controlled CIK cells; ELISA was used to analyze the expression of cytokines. Reverse transcription-polymerase chain reaction and immunohistochemistry were performed to evaluate the expression of ICOS ligand (ICOSL) in CIK cells and human cholangiocarcinoma cell line QBC939 cells. The cytotoxicity of CIK cells was determined either by lactate dehydrogenase-releasing assay in vivo or alteration of tumor size prior to and after the treatment of CIK cells in vivo. RESULTS CIK-ICOS cells proliferated more and expressed higher secretion a level of interferon-γ than the controlled CIK. These cells exhibited higher cytotoxicity against cholangiocarcinoma cell lines at all efficacy: toxicity (E:T) ratios tested than the controlled CIK cells. More importantly, the anti-ICOSL antibody was able to attenuate the elevated cytotoxicity mediated by ICOS overexpression. When injected into cholangiocarcinoma xenografts in severe combined immunodeficiency mice, CIK-ICOS cells survived better than the controlled CIK cells around xenografts and significantly reduced the growth rate of cholangiocarcinoma, with least volume increase and more severe necrosis of the xenografts than controlled mice treated with saline, CIK or CIK-enhanced green fluorescent protein. CONCLUSION ICOS can enhance the cytotoxic effect of CIK cells against cholangiocarcinoma both in vitro and in vivo. This effect is mediated by ICOS-augmented cytokine secretion and cell proliferation, and in part through ICOS-ICOSL interaction.

Abstract
This study was designed to develop a novel technical approach based on tumor-associated telomerase activity to detect cytotoxic activity of effector cells of the natural immune system against neoplastic cells. Human K562, DAUDI or Raji leukemia cells were co-cultured with NK or LAK effector cells at 37 degrees C for 4 h. Target cell killing was evaluated by 51Cr-release assay (CRA) or reduction of telomerase activity (R-TRAPCTX) of the target after exposure to effector cells. NK and LAK effector cells tested against K562 target cells at effector/target ratio of 50:1 showed cytotoxicity of 65% and 78%, respectively, with CRA and 51% and 74%, respectively, with R-TRAPCTX. Incorrect results were obtained with CRA when target cells were admixed with normal fibroblasts, whereas R-TRAPCTX was not influenced by the presence of normal cells. Control experiments performed with telomerase-negative cells showed that telomerase activity of effector cells was not altered during the cytolytic reaction. Moreover, supernatants obtained from effector-target cell co-cultures did not influence telomerase activity of targets. This novel R-TRAPCTX method to assay anti-tumor natural and possibly antigen-dependent cell-mediated cytotoxicity appears to provide sensible advantages over classical CRA or gamma-interferon release by effector cells in presence of target cells (ELISPOT), since (a) it furnishes reliable data on effector cell killing against neoplastic cells, even when malignant cells are admixed with normal cells, as frequently occurs in tumor biopsies, not manageable with CRA; (b) it provides an actual measure of target cell killing, not furnished by ELISPOT technique.

Abstract
The aim of this study was to evaluate the potential of tumor-necrosis-factor-related apoptosis-inducing ligand TRAIL to eradicate leukemia cell lines, while sparing normal hematopoietic stem cells. Human Jurkat and Molt-4 cell lines were used to optimize the purging process in umbilical cord blood (UCB) mononuclear cells. The Jurkat cell line was TRAIL sensitive and TRAIL-resistant Molt-4 cell line became sensitive after being treated with TRAIL and a low dose of doxorubicin (0.1 micro M), but UCB mononuclear cells remained resistant. DR4 expression was increased when Jurkat cells were treated with TRAIL, and DR5 expression increased after exposing Molt-4 cells to TRAIL plus a low dose of doxorubicin for 24 h. The expression of DR4 and DR5 in UCB mononuclear cells was unchanged after treatment with TRAIL, a low-dose doxorubicin, or TRAIL plus a low dose of doxorubicin. In TRAIL-sensitive Jurkat cells, caspases 8, 9, 3, and 7 were activated by TRAIL treatment and activation of caspases was augmented by TRAIL plus a low dose of doxorubicin than TRAIL or a low dose of doxorubicin alone in Molt-4 cells. Experiments involving mixture of UCB mononuclear cells and Jurkat or Molt-4 cells showed a marked eradication of leukemia cells and the limiting dilution assay demonstrated an eradication rate of more than 4 logs after 24 h incubation with 100 ng/ml of TRAIL in Jurkat cells. In the case of Molt-4 cells, the eradication rate was about 3 logs when TRAIL was used in combination with a low dose of doxorubicin. No significant decrease in the number of granulocyte-macrophage colony-forming unit) (CFU-GM) colonies was detected when UCB mononuclear cells were treated with TRAIL in combination with a low dose of doxorubicin. These results suggest that TRAIL offers the possibility of being used as an ex vivo purging agent for autologous transplantation in hematologic malignancies.

Abstract
Relatively little is known about the cytogenetics of natural killer (NK) neoplasms, and the emergence of recurrent structural alterations involving specific chromosomal breakpoints is still in its infancy. This gap has doubtless hampered identification of the oncogene alterations posited to underly NK tumors. We describe in detail the cytogenetic rearrangements present in a cytotoxic NK cell line (NK-92) established from a patient with large granular lymphocyte (LGL) lymphoma. The NK-92 cell line is one of very few cytotoxic NK cell lines described and the first to be used clinically. Cytogenetic analysis was performed independently using two multicolor-fluorescence in situ hybridization (M-FISH) systems, the first M-FISH study of a cell line derived from a NK neoplasm. Several non-random cytogenetic features previously reported in NK cells were, thus, identified, including rearrangements of chromosomes 7 and 17, along with breakpoints at 11q23, 12q12 and 8p22/23. FISH revealed that NK-92 cells carry multiple rearrangements with distinct breakpoints at 8p resembling those previously described in NK lymphoma. Our data strengthen the claim of NK-92 to model NK neoplasms and highlight this cell line as a potential resource for mining relevant oncogenic changes therein.

Abstract
AIM: To characterize the anticancer function of cytokine-induced killer cells (CIK) and develop an adoptive immunotherapy for the patients with primary hepatocellular carcinoma (HCC), we evaluated the proliferation rate, phenotype and the antitumor activity of human CIK cells from healthy donors and HCC patients in vitro and in vivo.
METHODS: Peripheral blood mononuclear cells (PBMC) from healthy donors and patients with primary HCC were incubated in vitro and induced into CIK cells in the presence of various cytokines such as interferon-gamma (IFN-γ), interleukin-1 (IL-1), IL-2, and monoclonal antibody (mAb) against CD3. The phenotype and characterization of CIK cells were identified by flow cytometric analysis. The cytotoxicity of CIK cells was determined by 51Cr release assay.
RESULTS: The CIK cells were shown to be a heterogeneous population with different cellular phenotypes. The percentage of CD3+CD56+ positive cells, the dominant effector cells, in total CIK cells from healthy donors and HCC patients, significantly increased from 0.1%-0.13% at day 0 to 19.0%-20.5% at day 21 incubation, which suggested that the CD3+CD56+ positive cells proliferated faster than other cell populations of CIK cells in the protocol used in this study. After 28 day in vitro incubation, the CIK cells from patients with HCC and healthy donors increased by more than 300-fold and 500-fold in proliferation cell number, respectively. CIK cells originated from HCC patients possessed a higher in vitro antitumor cytotoxic activity on autologous HCC cells than the autologous lymphokine-activated killer (LAK) cells and PBMC cells. In in vivo animal experiment, CIK cells had stronger effects on the inhibition of tumor growth in Balb/c nude mice bearing BEL-7402-producing tumor than LAK cells (mean inhibitory rate, 84.7% vs 52.8%, P < 0.05) or PBMC (mean inhibitory rate, 84.7% vs 37.1%, P < 0.01).
CONCLUSION: Autologous CIK cells are of highly efficient cytotoxic effector cells against primary hepatocellular carcinoma cells and might serve as an alternative adoptive therapeutic strategy for HCC patients.
