Project description:NK cells are innate immune cells that recognize and kill foreign, virally-infected and tumor cells without the need for prior immunization. NK expansion following viral infection is IL-2 or IL-15-dependent. To identify Runx3 responsive genes, NK cells were isolated from spleen of WT and Runx3-/- mice . Ten samples (5 WT and 5 Runx3-/-) of freshly isolated NK cells were separately obtained from individual mice. Cells were cultured for 7 days with IL-2 or IL-15.

Project description:We analyzed gene expression profiles of IL-18 generated murine NK cells in comparison to unstimulated, freshly isolated splenic NK cells. We identified a set of 1414 Affymetrix probe sets showing significant misregulation (Welch's T-test, p<0.05; Benjamini-Hochberg FDR corrected). IL-18 generated as well as unstimulated NK cells were isolated in three independent preparations and used for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Ex vivo activation and expansion of natural killer (NK) cells is a strategy to produce sufficient numbers of these effector cells for adoptive immunotherapy. Therefore we aimed at the development of an automated, clinical scale NK cell expansion process and compared NK cells after manual and automated expansion.We found only a small subset of 124 genes that significantly varied between both sample groups. These genes were associated with movement of leukocytes were identified including a group of genes for NK cell movement (CMKLR1, CX3CR1, S1PR5, GNLY and CXCR1) which were slightly higher expressed after automated compared to manual expansion. Nevertheless, the expansion profiles of NK cells after automated or manual expansion were rather similar in comparison to the remarkable difference between primary and expanded NK cells in general represented by the vast majority of regulated genes between the analyzed sample groups. Pathway analysis revealed that most of regulated genes upon expansion were associated with cell cycle regulation, DNA replication, DNA recombination and DNA repair, regulation of apoptosis and cell survival as well as cytokine signaling. Furthermore, the expression of many NK cell relevant markers was changed upon expansion with the strongest effects on up regulation of TRAIL and FASL, inhibitory TIGIT and chemokine receptors CCR2, CCR5 and CXCR6. In addition, granzyme M was down regulated but other important effector molecules like TNFa, perforin and granzymes A, B and K were up regulated. In summary we could show that manual and automatically expanded NK cells show a similar expansion profile while the differ significantly from primary NK cells. Up regulation of many NK cell relevant markers indicate for an enhanced NK cell functionaility after ex vivo activation and expansion. 24 samples were analyzed in total. 6 biological replicates represented by cells from different donors. 4 different samples per donor: freshly isolated NK cells (d0) and NK cells expanded for 14 days under 3 different conditions: in co-culture with EBV-LCL feeder cells and 500 U/mL IL2 either cultivated manually in T75 flasks (T) or automatically using the CliniMACS Prodigy system (P); NK cells cultured with 500 U/ml IL2 without feeder cells (I)

Project description:We studied the levels of expression of hundreds of mature miRNA's on an arrray (miRCURY, Exiqon, Cophenhagen, DN) for primary human T cells and NK cells. We found a 4% difference in the level of expression between these two cell types. NK and T cells were purified from peripheral blood mononuclear cells by negative selection from three healthy adult individuals, and total RNA was harvested. Samples reverse transcribed and studied on a microarry (miRCURY, Exiqon)

Project description:Natural Killer cells (NK), a major constituent of innate immune system, have the ability to kill the transformed and infected cells without prior sensitization; can be put to immunotherapeutic use against various malignancies. NK cells discriminate between normal cells and transformed cells via a balance of inhibitory and activating signals induced by interactions between NK cell receptors and target cell ligands. Present study investigates whether expansion of NK cells could augment their anti-myeloma (MM) activity. For NK cell expansion, peripheral blood mononuclear cells from healthy donors and myeloma patients were co-cultured with irradiated K562 cells transfected with 4-1BBL and membrane-bound IL15 (K562-mb15-41BBL). A genome-wide profiling approach was performed to identify gene expression signature in expanded NK (ENK) cells and non-expanded NK cells isolated from healthy donors and myeloma patients. A specific set of genes involved in proliferation, migration, adhesion, cytotoxicity, and activation were up regulated post expansion, also confirmed by flow cytometry. Exp-NK cells killed both allogeneic and autologous primary MM cells more avidly than non-exp-NK cells in vitro. Multiple receptors, particularly NKG2D, natural cytotoxicity receptors, and DNAM-1 contributed to target lysis, via a perforin mediated mechanism. In summary, vigorous expansion and high anti-MM activity both in vitro and in vivo provide the rationale for testing exp-NK cells in a clinical trial for high risk MM. Differential gene expression profile in expanded natural killer (ENK) cells and non-expanded natural killer (NK) cells from healthy donors and myeloma patients Eight healthy donor and eight myeloma patients were used in the study. Non-expanded natural killer (NK) cells were isolated from PBMCs of healthy donors and myeloma patients. Expanded natural killer (ENK) cells were generated from same set of samples as mentioned in expansion protocol. All ENK and NK cells were used for gene expression profiling.
