Expansion of highly cytotoxic human natural killer cells for cancer cell therapy.

Cancer research 20090421 9

Infusions of natural killer (NK) cells are an emerging tool for cancer immunotherapy. The development of clinically applicable methods to produce large numbers of fully functional NK cells is a critical step to maximize the potential of this approach. We determined the capacity of the leukemia cell line K562 modified to express a membrane-bound form of interleukin (IL)-15 and 41BB ligand (K562-mb15-41BBL) to generate human NK cells with enhanced cytotoxicity. Seven-day coculture with irradiated ...[more]

Project description:Goals and objectives of this study: to identify genes of the Treg signature induced by consitutive expression of GARP or FOXP3 in antigen-specific Th cells with potential role for stabililization & maintenance of the regulatory program. Keywords: T-cell receptor stimulation, gene-regulation, comparative gene expression profiling, cell type comparison, human, regulatory T cells, FOXP3, GARP Human alloantigen-specific Treg cells (THU) and Th cells (CD4-39), established and described recently (Ocklenburg et al.. Lab Invest.2006; 86: 724-737), were sitmulated for 3 days with cognate antigen (EBV B cells) and IL2 as described (Ocklenburg et al.. Lab Invest.2006; 86: 724-737) and analyzed using human Affymetrix U133 2.0 in monoplicate. Th cells had been transduced with a retroviral vector containing human GARP (LRRC32) or FOXP3 and an IRES-driven GFP as marker or empty GFP control, sorted for GFP+, expanded as described recently (Ocklenburg et al.. Lab Invest.2006; 86: 724-737), and characterized functially, phenotypically, and genetically as described (WO/2007/113301). Abbreviations: Treg THU d3 = alloantigen-specific Treg cells; GFP d3 = GFP-transduced alloantigen-specific Th cells (CD4-39); FoxP3 d3 = FOXP-transduced alloantigen-specific Th cells (CD4-39); Garp d3 = GARP-transduced alloantigen-specific Th cells (CD4-39); all stimulated for 3 days (=d3) with EBV B cells and IL2.

resting and IL2 activated human natural killer cells

Project description:The aim of the study was to investigate the activation of human NK cells by IL2 through analyzing the global gene expression at different time points (0, 2, 8 and 24 hours) after culture with the cytokine IL2 at 100 IU/ml. NK cells with the CD56+/CD16+ and CD3- phenotype were negatively selected by immunomagnetic beads and re-examined by flow-cytometry to ensure greater than 90% purity . Keywords: resting and IL2 activated NK cells(time series)

Expression data from human TCRVg9-positive gamma delta T lymphocytes

Project description:We used microarrays to detail the global programme of gene expression by circulating TCRVgamma9+ gamma delta T cells isolated from healthy individuals,tested either as resting cells or cells activated by phosphoantigen BrHPP and IL-2at an early(+6hrs) and a late (+7days) timepoint. We find that with more M-bM-^@M-^\NK cellM-bM-^@M-^] genes than alphabeta T cells and more M-bM-^@M-^\T cellM-bM-^@M-^] genes than NK cells, the circulating TCRVgamma9+ gamma delta T cells cells have a hybrid transcriptome. The gene signature of the activated cells recapitulates their physiological functions: Th1 cytokine, chemokine and cytotoxic activities at first and mitotic activity at later time points. The gene expression pattern of activated normal gamma delta T cells is nevertheless clearly distinctive from that of NK/T and peripheral T cell lymphomas of the gamma delta subtype. Human TCRVg9positive gamma delta T cells were isolated from PBMC by cell sorting (>98% purity) and activated for RNA extraction and hybridization on Affymetrix microarrays. Samples comprise cells before activation (control time 0), early after activation with BrHPP/IL2 (+6 hours) and at a later timepoint of the activated in vitro culture with BrHPP/IL2 (day 7).

Project description:Goals and objectives of this study: to identify genes preferentially induced in human CD4+CD25hi Treg cells following T-cell activation with potential role for stabililization & maintenance of the regulatory program. Keywords: T-cell receptor stimulation, gene-regulation, comparative gene expression profiling Homo sapiens CD4+CD25- and CD4+CD25hi T cells were sorted from healthy individual donors and analyzed ex vivo (non-activated) or 1 day following T-cell receptor activation using anti-CD3/IL2 and anti-CD3/-CD28/IL2 (activated), respectively.

Chemical Inhibition of Ezh2 Alters Ex Vivo B cell Differentiation and Gene Expression Dynamics

Project description:To understand the role of Ezh2 in B cell differentiation B cells were stimulated ex vivo with LPS, Il2, and Il5 in the presence of DMSO or the selective Ezh2 inhibitor GSK343. Following 3 days culture, activated B cells and Plasmablasts were FACS isolated and RNA-seq was performed to identify the molecular effects of Ezh2 inhibition on B cell subsets during differentiation.

IFN alpha-induced gene expression in human NK cells

Project description:NK cells are believed to contribute to the control of hepatitis C virus infection and pathogenesis of liver disease. Standard treatment of both acute and chronic hepatitis C is based on the administration of interferon alpha, however, the effects of type I interferons on human NK cells have not been studied in the context of hepatitis C. We therefore first performed a microarray screen for genes differentially regulated in human NK cells after stimulation of PBMC with recombinant interferon alpha-2b. One of the genes upregulated was TRAIL which was confirmed in vitro on the protein level. Keywords: Interferon alpha; human NK cells; stimulation for 6 hours; cells sorted after stimulation of whole PBMC NK cells of PBMC of five healthy controls have been either isolated directly or after culturing for 6h in media containing 10% human AB serum supplemented with 1 and 100 ng/ml recombinant IFNa-2b. RNA of NK cells of the healthy controls was isolated and RNA was pooled for the hybridization.

NK cell response to IL2 in vitro

Project description:Here we analyzed the transcriptional response to IL2 in NK cells in vitro. Splenic NK cells were isolated by negative selection from 6wk old male C57BL/6 mice. These were directly cultured with IL2 (250U/ml) for 8hrs in vitro. Cells were then transferred directly into TriZol. RNA was prepared in Trizol for gene expression profiling by Affymetrix Mouse Gene 1.0 ST Arrays. The samples in this series are re-analyzed samples from GSE84562.
