Project description:T-helper (Th) lineages have been generated in vitro by activating CD4 cells with anti-CD3/CD28 antibodies during polarization. Physiologically, however, the generation of Th lineages is by activation with the specific antigen presented by antigen-presenting cells (APC). Here, we used TCR-transgenic mice to compare the phenotypes of Th1, Th9 and Th17 lineages when generated by either one of the two activation modes. Lineage Th cells specific against hen egg lysozyme (HEL), were adoptively transferred into recipient mice transgenically expressing HEL in their lens. Remarkable differences were found between lineages of Th1, Th9, or Th17, generated by either one of the two modes in their capacities to migrate to and proliferate in the recipient spleen and, importantly, to induce inflammation in the recipient mouse eyes. Substantial differences were also observed between the lineage pairs in their transcript expression profiles of certain chemokines and chemokine receptors. Surprisingly, however, close similarities were observed between the transcript expression profiles of lineages of the three phenotypes, activated by the same mode. Furthermore, Th cell lineages generated by the two activation modes differed considerably in their pattern of gene expression, as monitored by microarray analysis, but exhibited commonality with lineages of other phenotypes generated by the same activation mode. This study thus shows that (i) Th lineages generated by activation with anti-CD3/CD28 antibodies differ from lineages generated by antigen/APC and (ii) the mode of activation determines to a large extent the expression profile of major transcripts NaM-CM-/ve CD4+ T cells purified from spleen and lymph node cells of 3A9 mice were activated and polarized toward Th1, Th9, and Th17 lineages, under either plate bound anti-CD3/anti-CD28 (PBAB) or APC presented HEL protein (HA).

Project description:The aim of this work was to identify functional features that are specific of human Treg cells, through the identification of genes that are differentially expressed: 1/ in activated Treg clones versus activated Thelper clones; 2/ in Th clones activated in the presence versus the absence of TGFb; 3/ in suppressed Th clones, i.e. Th clones activated in the presence of Treg clones, versus controls. Experiment Overall Design: Two to four million cells of human T cell clones were collected at rest (time point = 0) or after activation with coated anti-CD3 and soluble anti-CD28 antibodies (time points = 6, 24 or 41hrs). RNA was extracted for hybridization on Affymetrix microarrays.

Project description:In vitro culture of 2 separate sets of naive human T cells (from 2 adult male donors), activated using CD3 and CD28 antibodies. Secretome collection at 48 hours after activation. The same cell cultures not activated and sampled at the exact same time served as 'not-activated control'.

Project description:T-lymphocyte activation is efficiently mimicked in vitro by treatment with anti CD3 / anti CD28 antibodies. We report miR-21 induction upon CD3/CD28 stimulation of primary T-lymphocytes. In order to assess the function of miR-21 in T-lymphocytes we interfered with miR-21 function by lentiviral transduction of a miR-21 sponge construct. MRNA profile of miR-21 sponge and control transduced T-lymphocytes 48hrs after stimulation.

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:We next sought to identify the transcriptional program that differentiates IL-9+Th2 cells from “conventional” Th2 cells. To this end, we selected representative Th1, Th17, Th2, and IL-9+Th2 clones (Figure 5A) and determined their transcriptome in the resting state and at different time points after activation using RNAseq. Peripheral Blood Mononuclear Cells (PBMC) were isolated by Ficoll-Plaque Plus (GE Healthcare, UK) density gradient centrifugation. Human CD4+ T cells were isolated from PBMC by EasySep positive selection kit (Stemcell Technologies) according to manufacturer’s instruction. Positively selected CD4+ T cells were washed with PBS and stained for subsequent Th cell subset sorting. Memory Th cell subsets were sorted to over 90% purity according to their expression of chemokine receptors from CD45RA-CD25-CD8-CD3+ cells: Th1(CXCR3+CCR8-CCR6-CCR4-), Th2 (CXCR3-CCR8-CCR6-CCR4+), Th17 (CXCR3-CCR8-CCR6+CCR4+), Th9 (CXCR3-CCR8+CCR6-CCR4+). Single cell Th subset clones were directly sorted into 96well plate according to their expression of chemokine receptors (see above). Single cell clones were expanded and maintained by periodic restimulation with PHA (phytohaemaglutinine, 1 µg/ml, Sigma-Chemicals) and irradiated allogenic feeder cells (5x104/well) in culture medium. T cells were polyclonally activated using beads coated with antibodies against CD3, CD2, and CD28 (T cell/bead = 2:1, human T cell activation/expansion Kit, Miltenyi). Cell cultures were sampled before activation (time 0h) and 2, 4, 6, 9, 12, 24, and 48 hours after activation.
