Microarray analysis of WT and Tfap4-KO CD8 T cells during early activation

ABSTRACT: 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.

Although the transcription factor c-Myc is essential for the establishment of a metabolically active and proliferative state in T cells after priming, its expression is transient. It remains unknown how T cell activation is maintained after c-Myc expression is downregulated. Here we identified AP4 as the transcription factor that was induced by c-Myc and sustained activation of antigen-specific CD8+ T cells. Despite normal priming, AP4-deficient CD8+ T cells failed to continue transcription of a ...[more]

Gene expression analysis of WT and Tfap4–/– OT-I cells activated by Listeria monocytogenes expressing ovalbumin

Project description:Gene expression of Tfap4–/– and WT OT-I T cells were compared 4 or 6 days after activation with Listeria monocytogenes infection in vivo with the ERCC spike-in RNA control. Naive CD8+ T cells from Tfap4–/– OT-I or control WT OT-I TCR transgenice mice were adoptively transferred to congenic host mice that were subsequently infected with Listeria monocytogenes expression ovalbumin. Activated OT-I cells were harvested 4 days or 6 days after infection and gene expression was compared using microarray. 1 μL of 1:1,000 diluted External RNA Controls Consortium (ERCC) RNA Spike-In Control Mixes (Ambion) was added to total RNA extracted from 1 x 10^5 cells prior to amplification. Gene expression was quantitated by RMA normalization to Signal intensity and signal intensities were further converted by formula obtained from linear regression of signals for spiked-in control RNA between samples to obtain cell number-normalized gene expression.

Gene expression by antigen activated OT-I T cells in vivo in the presence and absence of IL-2

Project description:Much is known concerning the cellular and molecular basis for CD8+ T memory immune responses. Nevertheless, conditions that selectively support memory generation have remained elusive. Here we show that an immunization regimen that delivers TCR signals through a defined antigenic peptide, inflammatory signals through LPS, and growth and differentiation signals through the IL-2R initially favors antigen-specific CD8+ T cells to rapidly and substantially develop into tissue-residing T effector-memory cells by TCR transgenic OVA-specific OT-I CD8+ T cells. Amplified CD8+ T memory development depends upon a critical frequency of antigen-specific T cells and direct responsiveness to IL-2. A homologous prime-boost immunization protocol with transiently enhanced IL-2R signaling in normal mice led to persistent polyclonal antigen-specific CD8+ T cells that supported protective immunity to Listeria monocytogenes. These results identify a general approach for amplified T memory development that may be useful to optimize vaccines aimed at generating robust cell-mediated immunity. Gene expression analysis was performed for OT-I T cells on day 3 and day 5 after activation with ovalbumin and LPS in vivo with and without treatment with IL-2 using an agonists IL-2/anti-IL-2 complexes (IL2/Jes-6.1) OT-I T cells were purified and adoptively transferred into congenic syngenic mice. 24 hours later mice were immunization with ovalbumin and LPS. 24 hr later some mice received agonist IL2/anti-IL2. 3 and 5 days after immunization, the activated OT-I T cells were purifed by FACS and total RNA was isolated for genome wide expression analysis using Affymetrix Mouse Gene ST1.0 arrays

Whole-genome microarray analysis of primary, secondary, tertiary and quaternary memory CD8 T cells

Project description:The transcriptome of naive OT-I T cells was compared to memory CD8 T cells after 1, 2, 3, or 4 infection with ovalbumin expressing Listeria monocytogenes (LM-OVA). Naive Thy1.1 OT-I T cells were adoptively transferred into Thy1.2 naive hosts prior to infection with LM-OVA. The resulting memory CD8 T cell population was again adoptively transferred into naive hosts and the recipient mice were again infected with LM-OVA. The adoptive transfer was repeated up to four times to generate memory CD8 T cells with up to four consecutive antigen stimulations. Three individual mice were analyzed for each group. For quaternary memory CD8 T cells, spleens from two to three mice were pooled for each sample. Naive OT-I T cells served as control samples. http://dx.doi.org/10.1016/j.immuni.2010.06.014

Identification of miRNAs regulated by TGF-b in human CD8+ T cells (small RNA-seq)

Project description:The goal of the current study was to identify miRNAs regulated by TGF-b in human CD8+ T cells and analyze the function of these miRNAs in shaping the immunomodulatory effect of TGF-b in these cells. We identified the miR-23a cluster to be upregulated and found that this cluster could target key molecules (IFN-g and LAMP1) involved in immune response by CD8+ T cells. CD8+ T cells were isolated and purified from healthy human peripheral blood of 5 donors and were activated using beads coupled to anti-CD2, anti-CD3 and anti-CD24. They were then treated with 5ng/ml TGF-b, with 1ÂµM SD-208 or left untreated. RNA from these cells were then isolated and used for deep sequencing.

Differentially activated CD8 T cells in liver and gut

Project description:NaM-CM-/ve, liver- and gut-activated CD8 OT-I T cells show differential migration behaviour. To analyze which genes could be responsible for different migration patterns, naM-CM-/ve, liver-activated and gut-activated CD8 T cells were isolated and compared for their gene expression profile. Gene expression profiles of naM-CM-/ve CD8 OT-I T cells versus liver-activated T cells and gut-activated T cells, respectively. NaM-CM-/ve CD8 OT-I T cells were isolated from lymph nodes and spleens of OT-I mice. CD8 OT-I T cells activated by liver-derived and gut-derived antigen for three days in vivo, positive for CFSE were sorted from livers of TF-OVA mice or from mesenteric lymph nodes of iFABP-OVA mice. After total RNA extraction, reverse transcription, cDNA extraction, the biotinylated cRNA was transcribed, fragmented, and 15 M-BM-5g cRNA hybridized in duplicates for each of the three groups to the GeneChip arrays. Group1: naM-CM-/ve, Group2: liver-activated Group3: gut-activated. Lists of differentially regulated genes were created using High Performance Chip Data Analysis (HPCDA) with Bioretis database (http://www.bioretis-analysis.de). Worldwide data sharing is possible via Bioretis, please ask the authors.

Expression data from WT and TCF-1-deficient memory CD8 T cells

Project description:TCF-1 is an HMG family transcription factor which is known to be activated by the canonical Wnt signaling pathway and modulated by other signals such as those derived from T cell receptor. We found that during CD8 T cell responses, TCF-1 deficiency impaired long-term maintenance of antigen-specific memory CD8 T cells. We used microarrays to detect gene expression changes in memory CD8 T cells caused by TCF-1 deficiency. Host mice that received WT or TCF-1-deficient OT-I CD8 T cells were infected with attenuated Listeria monocytogenes expressing Ova peptide. In memory phase (i.e., more than 80 days post infection), antigen-specific T cells were ioslated by cell sorting. RNA was extracted and hybridized to GeneChip Mouse GENE 1.0 ST arrays (Affymetrix).
