Chracterising cellur pathways underlying CD3 CD28 activation of human CD4 cells

ABSTRACT: We devised an approach to disentangle the TCR and CD28 pathways upon stimulation in naive and memory primary human CD4+ T cells (Tcons) in response to defined stimulatory signals. Isolated memory and naÃ¯ve T cells were activated using anti-CD3, anti-CD28 or both in combination. As a control we cultured cells in the same conditions but without the stimuli. We carried Chipmentation using the H3K27ac antibody on 200,000 cross-linked cells. 1) This data is part of a pre-publication release.

Chracterising cellur pathways underlying CD3 CD28 activation of human CD4 cells

Project description:We devised an approach to disentangle the TCR and CD28 pathways upon stimulation in naive and memory primary human CD4+ T cells (Tcons) in response to defined stimulatory signals. Sorted Tcons were activated using a titration of anti-CD3 and anti-CD28 in combination as well as individually. As a control we cultured cells in the same conditions but without the stimuli. In total, we defined seven conditions from four individuals for sequencing. This data is part of a pre-publication release.

Transcriptome analysis of human memory T cell subsets from blood before and after ex-vivo CD3/CD28 stimulation

Project description:Naive, central memory (TCM), effector memory (TEM), and terminally differentiated effector memory RA (TEMRA, CD8+ only) T cell subsets were FACS separated from PBMC samples of four human donors using CCR7 and CD45RA as distinguishing cell surface markers. Samples were split and either immediately isolated, or incubated for 42-48 hours with anti-CD3/CD28 beads for ex-vivo stimulation.

ATAC-seq profiling of in vitro FRC-conditioned, IL6-conditioned or control (anti-CD3/CD28)-stimulated CD8+ T cells

Project description:To broadly assess which pathways FRCs regulate in CD8+ T cells, we sorted CD8+ T cells for ATAC-seq following activation in whole splenocyte mixtures via soluble anti-CD3/CD28 (0.25μg/ml) for 48 hours (Stim), activated with anti-CD3/CD28 in the presence of Nos2–/– FRCs (FRC) or activated with anti-CD3/CD28 plus 100 ng/ml recombinant IL-6 (IL-6). Here we demonstrate that FRC-derived signals, including IL-6, act in concert with TCR signaling and co-stimulation to remodel chromatin and render essential transcription factor binding motifs accessible in activated CD8+ T cells. Signals from FRCs led to increased binding regions for MYC, HIF-1α and HIF-1β, which are known to promote metabolic pathways following T cell activation. Additionally, FRC-derived signals promoted activity of transcription factors that regulate survival and memory programs in T lymphocytes such as BATF and BACH2.

RNA-seq time course on human CD4 memory T cells stimulated with anti-CD3/CD28 beads

Project description:In this study we sought to analyze the effects of genetic variants on gene regulation in a cell-state dependent manner during CD4 memory T cell activation. To do this, we performed an RNA-seq time series experiment on CD4 memory T cells activated with anti-CD3/CD28 beads in individuals with no autoimmune disease. We measured gene expression levels, and allele-specific expression at heterozygous sites over time. We found widespread dynamic genetic regulatory effects across the genome, with an enrichment for genes found in autoimmune disease risk loci.
