Project description:Gene expression of Tfap4â/â and WT CD8+ T cells were compared after activation with anti-CD3 and anti-CD28 antibodies in vitro or with Listeria monocytogenes infection in vivo For in vitro activation, naive CD8+ T cells were purified from WT and Tfap4â/â mice and activated with anti-CD3 and anti-CD28 antibodies for 72 hours. For in vivo activation, naive CD8+ T cells from Tfap4â/â OT-I or control WT OT-I TCR transgenice mice were adoptively transferred to congenic host mice that were subsequently infected with Listeria mnocytogenes expression ovalbumin. Activated OT-I cells were harvested 48 hours after infection.

Project description:MicroRNA-155 (miR-155) is upregulated in primary effector CD8 T cells but is expressed at low amounts in naïve cells. Anti-viral CD8 T cell responses and viral clearance were impaired in miR-155 deficient (bic-/-) mice, and this defect was intrinsic to CD8 T cells, as adoptively transferred bic-/- CD8 T cells generated greatly reduced primary and memory responses during infection. To understand the mechanism by which miR-155 regulates CD8 T cell activation, we analyzed the gene expression profiles of naive and in vitro activated wild-type and bic-/- CD8 T cells. CD8 T cells were purified from uninfected C57BL/6 mice and stimulated in vitro with plate-bound anti-CD3 and anti-CD28 antibodies for 48 h or left unstimulated. RNA from these CD8 T cells was processed, amplified, labeled, and hybridized to Affymetrix GeneChip MoGene 1.0 st microarrays.

Project description:IFN alpha mediated gene expression pattern. The effect of IFN alpha on human CD8 T cells responding to antigen (signal 1) and costimulatory signals (signal 2) provided by beads coated with anti-CD3 and anti-CD28 mAbs. This analysis examined the effects of IFN alpha on human CD8 T cells responding to antigen (signal 1) and costimulatory signals (signal 2) provided by beads coated with anti-CD3 and anti-CD28 mAbs. Magnetically sorted untouched CD8+CD45R0- T cells from three different donors were unstimulated or stimulated with IFNa2b or with anti-CD3/CD28 Beads alone or along with IFNa2b or IFNa5 for 48 hours. Individual mRNA samples were analyzed using HG-U133A 2.0 array gene chips. Keywords: Gene expression analysis after different stimulation Magnetically sorted untouched CD8+CD45R0-T cells from three different donors (named A, B and C) unstimulated or stimulated with IFN alpha 2b or with anti-CD3/CD28 beads alone or along with IFN alpha 2b or IFN alpha 5 for 48 hours.

Project description:The Tec-family kinase Itk plays an important role during T-cell activation and function, and controls also conventional versus innate-like T-cell development. We have characterized the transcriptome of Itk-deficient CD3+ T-cells, including CD4+ and CD8+ subsets, using Affymetrix microarrays. The largest difference between Itk-/- and Wt CD3+ T-cells was found in unstimulated cells, e.g. for killer cell lectin-like receptors. Compared to anti-CD3-stimulation, anti-CD3/CD28 significantly decreased the number of transcripts suggesting that the CD28 co-stimulatory pathway is mainly independent of Itk. The signatures of CD4+ and CD8+ T-cell subsets identified a greater differential expression than in total CD3+ cells. Cyclosporin (CsA)-treatment had a stronger effect on transcriptional regulation than Itk-deficiency, suggesting that only a fraction of TCR-mediated calcineurin/NFAT-activation is dependent on Itk. Bioinformatic analysis of NFAT-sites of the group of transcripts similarly regulated by Itk-deficiency and CsA-treatment, followed by chromatin-immunoprecipitation, revealed NFATc1-binding to the Bub1, IL7R, Ctla2a, Ctla2b, and Schlafen1 genes. Finally, to identify transcripts that are regulated by Tec-family kinases in general, we compared the expression profile of Itk-deficient T-cells with that of Btk-deficient B-cells and a common set of transcripts was found. Taken together, our study provides a general overview about the global transcriptional changes in the absence of Itk. Experiment Overall Design: CD3+ CD4+ and CD8+ T-cells from pooled suspensions of spleen and lymph nodes of Wt and Itk knockout mice on C57BL/6 background were isolated after negative depletion. Unstimulated as well as stimulated T-cells were studied. Stimulations were done with anti-CD3 (1 mg/ml) for 24 hrs. For the CD4+ T-cells we collected triplicates from the Itk knockout mice and duplicates from the Wt group. For the CD8+ T-cells, we got duplicates from Itk knockout , while we obtained a single sample from Wt owing to the low cell yield for resting Wt CD8+ T-cells. After CD3-stimulation we got a single sample from the CD8+ subset of both Wt and Itk knockout, while for the CD4+ subsets we collected duplicates.

Project description:Mouse CD4 naïve T cells, isolated from spleens of WT or TLGMNKO mice, were activated with plate-bound anti-mouse CD3 and soluble anti-mouse CD28 for 3 days, and then characterized by 4D label-free proteomic analysis using nano-liquid chromatography-tandem mass spectrometry

Project description:The purpose of this study was to determine which genes are differentially regulated by the E3 ligase Nrdp1 in CD8+ T cells after treatments with anti-CD3/CD28 Abs. The results demonstrate increased induction of cytotoxicity-associated genes in Nrdp1-/- mice than in Nrdp1+/+ mice after activation. Thus Nrdp1 may be involved in the regulation of TCR signaling. Naive CD8+ T cells derived spleens of Nrdp1+/+ and Nrdp1-/- mice were either untreated or treated with immobilized anti-CD3 (5 μg/ml) and soluble anti-CD28 (1 μg/ml) Abs for 4h or 8h. Equal amounts of RNA were assayed for gene expression using Affymetrix mouse 430 2.0 arrays.
