Project description:GBM is the most common and aggressive primary brain tumor with dismal prognosis. NK cells are large granular lymphocytes with natural cytotoxicity against tumor cells, and they should be established for the novel treatment against patients with GBM. We have previously reported highly activated and ex vivo-expanded NK cells derived from human peripheral blood, which is designated as Genuine-induced natural killer cell (GiNK), induced by our specific culture conditions exerted the cytotoxic effect on GBM cells via apoptosis. First, we comprehensively summarized the molecular characteristics, especially focusing on the expression of stem cell markers, extracellular matrix markers, chemokine, chemokine receptors, and the NK receptors’ ligands, of GBM spheroids compared with 2D adherent GBM cells by using microarray. In the spheroid derived from GBM cell lines, gene expression of stem cell markers, extracellular matrix markers, chemokine, chemokine receptor, NK cell inhibitory receptor’ ligand were up-regulated compared with 2D adherent GBM cells. A preclinical evaluation of the NK cells was performed by ex vivo 3D spheroid model derived from GBM cell lines. In 3D spheroid model, the NK cells accumulated and infiltrated around the spheroids and induced the GBM cell death. Flow cytometry-based apoptosis detection assay clearly showed that the NK cells induced the GBM cell death via apoptosis. Our findings could provide pivotal information for the NK cell based-immunotherapy to patients with GBM.

Project description:Glioblastoma (GBM) is the most common and aggressive primary brain tumor, with a dismal prognosis. Natural killer (NK) cells are large granular lymphocytes with natural cytotoxicity against tumor cells, and they should be established for the novel treatment of patients with GBM. We previously reported highly activated, and ex vivo-expanded NK cells derived from human peripheral blood, designated genuine induced NK cells (GiNK), which were induced by specific culture conditions and which exerted a cytotoxic effect on GBM cells via apoptosis. Here, we comprehensively summarize the molecular characteristics, especially focusing on the expression of stem cell markers, extracellular matrix markers, chemokines, chemokine receptors, and NK receptor ligands of spheroids derived from GBM cell lines as compared with that of two-dimensional (2D) adherent GBM cells via microarray. The spheroid had upregulated gene expression of stem cell markers, extracellular matrix markers, chemokines, chemokine receptors, and NK cell inhibitory receptor ligands compared with the 2D adherent GBM cells. Preclinical evaluation of the NK cells was performed via an ex vivo 3D spheroid model derived from GBM cell lines. In the model, the NK cells accumulated and infiltrated around the spheroids and induced GBM cell death. Flow cytometry-based apoptosis detection clearly showed that the NK cells induced GBM cell death via apoptosis. Our findings could provide pivotal information for NK cell-based immunotherapy for patients with GBM.

Project description:In this study we have compared the proteomic profile of extracellular vesicles (EVs) prepared from primary, human NK cells or the human NK cell lines NK-92 and KHYG-1 cultured for 48hrs in serum-free conditions. EVs were harvested from cells either under resting conditions (culture in IL-15) or upon activation (combination of IL-12, IL-15, and IL-18). In addition, primary NK cells were activated in the presence of anti-CD16-coated beads, and EVs harvested after 48hrs. The aim was to compare their ability to target and kill a variety of tumor cell line-derived spheroids

Project description:NK cells are lymphocytes that provide a first defense against viral infections and cancer. They act (i) cytotoxic by killing virus-infected and tumorigenic cells and (ii) immune regulatory by releasing cytokines and chemokines. These innate immune cells are commonly further classified as CD56bright and CD56dim NK cells. Former studies confirmed immune regulatory CD56bright NK cells as progenitors of cytotoxic CD56dim NK cells. CD57 was previously described as T cell marker for senescence and terminal differentiation. Recent studies detected CD57+ and CD57- NK cells among the CD56dim NK cell population and suggested a fully mature developmental status for CD57+ NK cells. The recent NK cell maturation model includes CD34+ hematopoietic stem cells (HSC), which develop into CD56bright NK cells, later into CD56dimCD57- and finally into terminally maturated CD56dimCD57+ (1) (2) (3). The molecular mechanisms of human NK cell differentiation and maturation remain unknown to this date. We performed for the first time a proteomic analysis of these distinct developmental stages of human primary NK cells, isolated from overall 10 healthy human blood donors. CD56bright NK cells versusCD56dim and CD56dimCD57- versus CD56dimCD57+ NK cells were analyzed by using quantitative peptide sequencing, which revealed individual protein signatures (3400 proteins) of these different NK cell developmental stages. Notably, our data support the current NK cell differentiation model by highlighting both strong distinctions between CD56dim/bright NK cells and close relationships between CD57+/- NK cells on the proteomic level. Among the most prominent and conserved regulated proteins, we detected myosin IIa, Calvasculin and Calcyclin with very similar expression patterns. We investigated their sub-cellular localization and observed specific recruitment- and accumulation-events at the NK cell immunological synapse (NKIS) after NK activation.

Project description:Penetration of immune cells into tumor cells was believed to be immune-suppressive via cell-in-cell (CIC) mediated death of the internalized immune cells. We unexpectedly found that CIC formation largely led to the death of the host tumor cells, but not the internalized immune cells, manifesting typical features of death executed by NK cells, which we called “in-cell killing” that demonstrates efficacy superior to the canonical way of “kiss killing” from outside. By expression profiling of isogenic cells, CD44 on tumor cells was identified as a negative regulator of “in-cell killing” via inhibiting CIC formation. CD44 functions to antagonize NK cell internalization by reducing N-cadherin-mediated intercellular adhesion and enhancing Rho GTPase-regulated cellular stiffness as well. Remarkably, antibody-mediated blockade of CD44 signaling potentiated the suppressive effects of NK cells on tumor growth associated with increased heterotypic CIC formation. Together, we identified CIC-mediated “in-cell killing” as a promising strategy for cancer immunotherapy.
