Expression data from WT and IL-2 secondary CD4 T cell effectors responding towards infuenza A virus infection

ABSTRACT: How IL-2 produced by secondary CD4 T cell effectors, derived from resting memory cells, impacts memory CD4 T cell function and survival to memory following antigen re-encounter is unknown. We used microarrays to detail the global programme of gene expression underlying differences between WT and IL-2 deficient secondary CD4 T cell effectors purified from the lung on day 7 following A/PR8/34-OVAII influenza infection. Congenic primed memory DO11.10 TCR trangenic CD4 T cells were sort purifed from the lungs of infected mice on day 7 post infection for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain only CD4 T cell populations that had entered into the immune response by also sorting and collecting only those cells that had divided at least 5 times by CFSE analysis.

It is unclear how CD4 T-cell memory formation is regulated following pathogen challenge, and when critical mechanisms act to determine effector T-cell fate. Here, we report that following influenza infection most effectors require signals from major histocompatibility complex class II molecules and CD70 during a late window well after initial priming to become memory. During this timeframe, effector cells must produce IL-2 or be exposed to high levels of paracrine or exogenously added IL-2 to su ...[more]

Project description:Gene expression profiling of repeatedly activated compared to recently activated Th1 cells to identify genes that play a role in chronic inflammatory disorders and may qualify as diagnostic or therapeutic targets; ; Upon activation under appropriate costimulatory conditions, naive T helper (Th) cells differentiate into Th2 or Th17 cells, each characterized by the expression of specific effector cytokines. In response to a repeated stimulation with antigen, Th cells develop a stable memory for the expression of those cytokines as well as for other secreted or membrane-associated factors. The stable memory for the expression of proinflammatory effector functions may explain the resistance of Th effector cells to conventional immunosuppressive therapy, and the inability of immunosuppression to cure chronic inflammation. The imprinting of the functional memory is based on epigenetic modifications and expression of distinct transcription factors. In this project, we compare the transcriptomes of once and repeatedly activated murine Th1 cells, to identify genes that induce and maintain the functional memory and control the persistence of pathogenic memory Th1 cells. This in turn might help to discriminate pathogenic versus protective cells in immunopathology and present novel targets for the diagnosis and therapy of chronic inflammatory disease. Experiment Overall Design: Genes differentially expressed in once versus four times stimulated Th1 cells. In vitro polarization of murine naÃ¯ve DO11.10 T cells towards Th1 direction (5 ng/ml recombinant murine IL-12, 5 Î¼g/ml anti-IL-4 antibody) with antigenic stimulation (ova323-339 and irradiated splenic APCs). The transcriptional profiles of resting one week old Th1 (Th1 1w) cells and resting 4 week old Th1 (Th1 4w) cells were compared using Affymetrix Murine Genome (MG) U74V2A GeneChip arrays. Experiment Overall Design: 10 Âµg of total RNA from each cell sample was reverse transcribed using T7-(d)T24 primer and SuperScript II reverse transcriptase Experiment Overall Design: cDNA extraction with a PhaseLock gel (Eppendorf), and precipitation with ethanol and ammonium acetate Experiment Overall Design: Biotinylated cRNA was transcribed with the MEGAscript high yield transcription kit (Ambion), fragmented, and the hybridization cocktail was prepared (15 Âµg fragmented biotin-labeled cRNA spiked with Eukaryotic Hybridization control) Experiment Overall Design: probes were subsequently hybridised with the GeneChip U74Av2 for 16 hrs at 45 oC Experiment Overall Design: after washing the hybridisation signals were visualised by staining with streptavidin-phycoerythrin and amplification with an anti-streptavidin antibody Experiment Overall Design: TH1_1w_C1; TH1_1w_C2; TH1_1w_C3TH1_4w_C1; TH1_4w_C2; TH1_4w_C3 Experiment Overall Design: 1w: 1 week in culture; 4w: 4 weeks in culture; C1-3: Culture or Experiment No.

Project description:Tumors express a wide variety of both mutated and non-mutated antigens. Whether these tumor antigens are broadly recognized as âselfâ or âforeignâ by the immune system is currently unclear. Using an autochthonous prostate cancer model in which hemagglutinin (HA) is specifically expressed in the tumor (ProHA x TRAMP mice), as well as an analogous model wherein HA is expressed in normal tissues as a model self-antigen (C3HAHigh), we examined the transcriptional profile of CD4 T cells undergoing antigen-specific division. Consistent with our previous data, transfer of antigen-specific CD4 T cells into C3HAHigh resulted in a functionally inactivated CD4 T cell profile. Conversely, adoptive transfer of an identical CD4 T cell population into ProHA x TRAMP resulted in the induction of a regulatory phenotype (Treg) both at the transcriptional and functional level. Interestingly, this Treg skewing was a property of even early-stage tumors, suggesting Treg induction as an important tolerance mechanism during tumor development. The goal of this microarray is to detail the transcriptional profile differences between CD4 T cells that recognize their cognate antigen in the context of tumor (ProHA x TRAMP model) or self-antigen recognition (C3HA) or viral-antigen recognition (VaccHA) models or unprimed naÃ¯ve state (Nontransgenic). The comparison contains both upregulated and downregulated transcripts. Experiment Overall Design: TCR transgenic CD4 T cells specific for hemagglutinin (HA) were adoptively transferred into tumor-antigen recognition model (ProHA x TRAMP), Self-antigen recognition model (C3HA), viral-antigen recognition model (VaccHA), and naÃ¯ve control (Nontrangenic). Divided (CFSE diluted) CD4 T cells were sorted by FACS, RNA was extracted, and biological replicated were hybridized to an Affymetrix Mouse 430 Plus 2 expression array, followed by interrogation with an Affymetrix GeneChip Scanner 3000. RMA normalization was employed to identify differentially expressed transcripts.

Project description:The basic helix-loop-helix transcriptional repressor twist1, as an antagonist of nuclear factor ÎºB (NF-ÎºB)-dependent cytokine expression, is involved in the regulation of inflammation-induced immunopathology. We could show that twist1 is expressed by activated T helper (Th) 1 effector memory cells. Induction of twist1 in Th cells is dependent on NF-ÎºB, nuclear factor of activated T cells (NFAT), and interleukin (IL)-12 signaling via signal transducer and activator of transcription (STAT) 4. Expression of twist1 is transient following T-cell receptor engagement, and increases upon repeated stimulation of Th1 cells. Imprinting for enhanced twist1 expression is characteristic of repeatedly restimulated effector memory Th cells and thus of the pathogenic memory Th cells of chronic inflammation. Th lymphocytes from the inflamed joint or gut tissue of patients with rheumatic diseases, Crohnâ??s disease or ulcerative colitis express high levels of twist1. Expression of twist1 in Th1 lymphocytes limits the expression of the cytokines interferon-Î³, IL-2 and tumor necrosis factor-Î±, and ameliorates Th1-mediated immunopathology in delayed-type hypersensitivity and antigen-induced arthritis. In order to identify the effect of twist1 expression on the function of Th cells, twist1 was ectopically expressed and the transcriptome was compared to empty-virus infected control cells. In addition, this experiment allows for the identification of genes regulated by the transcription factor twist1. Experiment Overall Design: Genes differentially expressed upon ectopic twist1 overexpression. Splenic DO11.10 cells were activated in vitro with the cognate peptide ova327-339 in the presence of 1ng/ml IL-12 and 1ng/ml IL-2. On day 2 cells were infected with control virus, or twist1-encoding virus. On day 5 cells were sorted according to expression of the viral marker gene gfp. Cells were restimulated for four hours with PMA/ionomycin. The transcriptional profiles of duplicates of cultures were compared using Affymetrix Murine Genome (MG) 430A 2.0 GeneChip arrays.
