RNA sequencing analysis of anti-CD3/CD28 stimulated wild type-OT1 (WT) and Lrch1-/- -OT1 (KO) CD8+ T cells

Project description:We report the differential gene expression between anti-CD3/CD28 stimulated WT and LRCH1-deficient CD8+ T cells. Improving cytotoxicity, proliferation and infiltration ability of CD8+ T cells is critical in T cell immunotherapies against tumors. This study has identified LRCH1 as a negative regulator of LAT-mediated TCR signal transduction, as LRCH1 inhibits LAT signalosome formation and facilitates the endocytosis of LAT on the plasma membrane. LRCH1-deficient CD8+ T cells are more proliferative and effective at pathogen control and tumor elimination. Importantly, CRISPR/Cas9-mediated knockout of LRCH1 in human T cells also increases IFN-γ production, cell proliferation and migration ability in vitro. These data suggest LRCH1 as a potential target to improve CD8+ T cell responses against tumor and pathogens.

Genome wide expression profiles (RNAseq) of human CD8+ T cells in resting, activated (CD3+CD28) and PD-1-stimulated cells (CD3+CD28+PD-L1-Fc) at diferent time points

Project description:Background: Binding of the programmed death-1 (PD-1) receptor to its ligands (PD-L1/2) transduces inhibitory signals that promote exhaustion of activated T cells. Blockade of the PD 1 pathway is widely used for cancer treatment, yet the inhibitory signals transduced by PD-1 in T cells remain elusive. Methods: Expression profiles of human CD8+ T cells in resting, activated (CD3+CD28) and PD-1-stimulated cells (CD3+CD28+PD-L1-Fc) conditions were evaluated by RNA-seq. Bioinformatic analyses were used to identify signaling pathways differentially regulated in PD 1-stimulated cells.

Expression data from human peripheral blood lymphocytes stimulated with anti-CD3 and anti-CD28 antibodies.

Project description:Peripheral blood lymphocytes were separated in the Ficoll gradient and subjected for stimulation with anti-CD3 and anti-CD28 antiobodies upon time (6h, 12h and 18h). Next, total RNA was isolated and trenscriptional analysis of stimulated cells was performed.

IL-23 100ng/ml Treatment of CD3 CD28 Stimulated PBMCs

Project description:Cryopreserved human PBMCs from six donors were stimulated with anti-CD3/CD28 beads in the presence or absence of 100ng/ml IL-23 for 22 hours. RNA samples were assessed for consistency with a Bioanalyzer (Agilent) and quantified by a Nanodrop® ND 1000 Spectrophotometer (Nanodrop Technologies, USA). Expression array data was quantile normalised, detection above background statistical testing performed, comparison between activated un-stimulated versus activated IL-23 stimulated conditions performed as a paired test using the Illumina Custom differential expression algorithm (all implemented in Illumina BeadStudio GeneExpression Module v3.2). Two sample groups were compared, each with 6 biological replicates. Group 1 was stimulated with CD3CD28 antibody coated beads as a control group for 22hours. Group 2 was stimulated as the control group and treated with IL-23 100ng/ml for the same time period. Keywords: Cytokine Treatment

RNA-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 RNA-seq following activation in whole splenocyte mixtures via soluble anti-CD3/CD28 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 promote the expression of MYC and HIF-1-dependent glycolytic genes and vital pro-survival genes (encoding BCL-2 family members, inhibitors of apoptosis [IAPs] members and Cflar) in activated CD8+ T cells.
