Project description:Natural Killer Gene Complex (NKC)-encoded immunomodulatory C-type lectin-like receptors (CTLR) include members of the NKRP1 and CLEC2 gene families, which constitute genetically linked receptor-ligand pairs and are thought to allow for NK cell-mediated immunosurveillance of stressed or infected tissues. The mouse CTLR Nkrp1g was previously shown to form several receptor-ligands pairs with the CLEC2 proteins Clr-d, Clr-f, and Clr-g, respectively. Recently, we demonstrated a gut-restricted expression of Clr-f on intestinal epithelial cells that is spatially matched by Nkrp1g on subsets of intraepithelial lymphocytes (Leibelt et al., 2015). We now investigated expression and ligand interaction of Nkrp1g in the splenic compartment, and found an exclusive expression of Nkrp1g on a small subset of NK cells that upregulates Nkrp1g after cytokine exposure. To further characterize NKrp1g+ NK cells, we performed microarray analysis of resting Nkrp1g+ versus Nkrp1g- splenic NK cells that were purified by FACsorting. Total RNA isolation was followed by an Affymetrix microarray analysis.

Project description:ChIP-seq was conducted using freshly isolated splenic WT NK cells from IL-15/Ra treated mice with anti-Runx3 antibody (Ab) and non-immune serum (NIS) as control. Runx3 and NIS IP from splenic NK cells of IL-15/Ra treated WT mice, isolated by negative selection using NK cell isolation kit (R&D) followed by sorting of NKp46+ cells.

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).

Project description:ChIP-seq was conducted using splenic WT NK cells cultured for 7 days with IL-2 using anti-Runx3 antibodies (Ab), anti-H3K4me1 Ab and non-immune serum (NIS) as control. Two biological Runx3, one H3K4me1 and two NIS IP repeats from splenic NK cells isolated from individual mice by negative selection using NK cell isolation kit (R&D) cultured with IL-2.

Project description:Purpose: For comparing the transcript changes, we conducted mRNA-sequencing of splenic NK cells from Ncr1Cre-Mettl3fl/fl (cKO) and Mettl3fl/fl (WT) mice. Method: Firstly, The splenic NK cells (CD45.2+CD3-NK1.1+NKp46+) are purified via Fluorescence activated Cell Sorting (FACS), then frozen in -80 °C ultra-low temperature refrigerator, followed by High-throughput sequencing, in three replicates, using Illumina Hiseq 1500 platform. Result: Using standard data process workflow, we found the differentailly expressed genes in NK cells from Ncr1Cre-Mettl3fl/fl (cKO) mice, compared with those from Mettl3fl/fl (WT) mice.

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:Dendritic cells (DCs) are a complex group of cells which play a critical role in vertebrate immunity. They are subdivided into conventional DC (cDC) subsets (CD11b and CD8alpha in mouse) and plasmacytoid DCs (pDCs). Natural killer cells are innate lymphocytes involved in the recognition and killing of abnormal self cells, including virally infected cells or tumor cells. DCs and NK cells are activated very early upon viral infections and regulate one another. However, the global responses of DC and NK cells early after viral infection in vivo and their molecular regulation are not entirely characterized. The goal of this experiment was to use global gene expression profiling to assess the global genetic reprogramming of DC and NK cells during a viral infection in vivo, as compared to B lymphocytes, and to investigate the underlying molecular mechanisms This study includes data from cell sort purified DCs, NK cells and B cells isolated from the spleen of MCMV-infected mice. 2 independent replicates were made for each cell type except B cells. The control dataset for cells isolated from uninfected control animals has been previously published and is available in the GEO database as GSE9810. The complete dataset representing: (1) the infected Samples and (2) the uninfected control Samples from Series GSE9810 (re-processed using RMA), is linked below as a supplementary file. Comparison of the gene expression programs of wild-type spleen leukocyte subsets, including plasmacytoid DCs, CD8alpha conventional DCs, CD11b conventional DCs and NK cells, isolated from MCMV-infected versus control animals.
