Project description:The purpose of this study is to obtain an "in vivo" confirmation that mesalazine induces the gene expression of μ-protocadherin and other related genes in the colon mucosa, as demonstrated in some "in vitro" experiments. .
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:In the VILLIN-HA/CL4-TCR transgenic mouse model a population of CD8 T cells with suppressive capacities was indentified. For the molecular characterisation of CD8 regulatory T cells gene comparative expression profiles of naive, activated and regulatory CD8 T cells were performed. Three population of CD8 T cells are included in the analysis. 1. CD8 T cells 2. in vivo activated CD8 T cells 3. in vivo generated CD8 regulatory T cells
Project description:To understand differences between resting and activated memory CD8+ T cells, we compared the global gene expression of ex vivo isolated naive and spleen and BM memory cells to in vitro activated spleen and BM memory cells.
Project description:Interleukin 2 (IL-2) promotes proliferation and differentiation of CD8+ T cells in vitro and in vivo. To define gene expression regulated by IL-2, we purified naive CD8+ T cells, activated them for 2 days followed by treatment with recombinant IL-2 or with neutralizing antibody against IL-2 and compared gene expression between the two treatments.
Project description:To investigate the difference in gene expression of liver cancer cells after co-culture with activated CD8+T cells , we established a tumor cells/activated CD8+T cells co-culture system in which murine liver cancer cell line hepa1-6 were co-cultured and attacked directly by murine in vitro activated spleen naive CD8+T cells (effector: target=5:1) for 48 hours. We then performed gene expression profiling analysis using data obtained from RNA-seq of two different groups (immune attacked or control) with 5 repetitions per group.
Project description:To investigate the TVA's effect on mouse CD8+ T cells in vitro, we treated activated mouse CD8+ T cells with DMSO or 20 µM TVA for 24 hours. We then performed gene expression profiling analysis using data obtained from RNA-seq.
Project description:Interleukin 2 (IL-2) promotes proliferation and differentiation of CD8+ T cells in vitro and in vivo. To define gene expression regulated by IL-2, we purified naive CD8+ T cells, activated them for 2 days followed by treatment with recombinant IL-2 or with neutralizing antibody against IL-2 and compared gene expression between the two treatments. Total RNA was extracted using the NucleoSpin RNA XS kit (Macherey-Nagel), amplified using a PicoSL RNA amplification kit (Nugen) and biotinylated with Encore biotin module (Nugen). Labeled RNA was hybridized to Mouse Gene 1.0ST microarrays (Affymetrix) according to the manufacturer’s instruction.
Project description:To investigate the effect of the addition of STAT3-/+ astrocyte derived-conditioned medium in CD8+ T cells previously activated in vitro We then performed gene expression profiling analysis using data obtained from RNA-seq of 3 CD8+ T cells cultures of STAT3- conditon and 3 CD8+ T cells cultures of STAT3+ conditon
