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. 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.

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. Isolated memory and naÃƒÂ¯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.

T helper Cell differentiation

Project description:Study was designed to compare the transcriptome of Th2 cells in presence or absence of 4m8c. Murine splenic naive T helper cells were activated in presence of anti-CD3e, anti-CD28 antibodies and IL4 and IL2 cytokines for 3 days. Cells were then transferred from activation plate to resting for 3 days. Cells were reactivated by anti-CD3e antibidy. Similar culture were maintained in presence of 15uM 4m8c.This data is part of a pre-publication release.

DPY30 ChIP seq

Project description:H9 human embryonic stem cells (hESCs) were cultured in feeder-free chemically-defined conditions in medium containing 10ng/ml Activin A and 12ng/ml FGF2 (Vallier L. 2011, Methods in Molecular Biology, 690: 5766). Chromatin immunoprecipitation was performed as described in Brown S. et al. 2011. Stem Cells 29: 117685 by using 5ug of anti-DPY30 antibody (Sigma, cat. number HPA043761). This protocol was performed in control hESCs (expressing a scrambled shRNA) and in hESCs stably expressing an shRNA against DPY30 (Sigma, clone n. TRCN0000131112).This data is part of a pre-publication release.

Effect of costimulation on microRNAs levels in human naïve CD4 T cells

Project description:microRNA transcriptional profiling of human naïve CD4 T cells comparing cells that saw no activation, only anti-CD3 or anti-CD3 and anti-CD28 to identify microRNAs specifically upregulated by CD28-mediated costimulation. Three conditions experiment. PBS, anti-CD3, anti-CD3 + anti-CD28 all compared to a reference sample. Biological triplicates, independently extracted and activated.

Phosphoproteomic analysis of T cell receptor stimulation-induced changes in human primary CD4+CD25- T cells in the absence or presence of regulatory T cells.

Project description:Regulatory T cells (Tregs) suppress other immune cells and are indispensable for human health, yet the molecular mechanisms of suppression remain incompletely understood. Tregs can suppress proliferation and cytokine production of CD4+CD25- conventional T cells (Tcons). We previously demonstrated that human Tregs rapidly suppress T cell receptor (TCR)-induced calcium, NFAT and NF-κB pathways in Tcons, leading to inhibition of effector cytokine transcription (Schmidt A et al., Science Signaling 2011 Dec 20;4(204):ra90. doi: 10.1126/scisignal.2002179). Due to the short time period required to induce suppression, it is probable that Tregs alter protein modifications, such as (de)phosphorylations, in suppressed Tcons to cause this inhibition of particular TCR signaling events, while de novo production of repressor proteins seems unlikely. Thus, in order to identify causative factors which initiate rapid Treg-mediated suppression of Tcons, we compared phosphoproteomes of 5 minutes TCR-stimulated responder Tcons re-isolated from cocultures with primary human Tregs with those from control cocultures (Tcons cocultured with other Tcons). In addition, we measured the basal state of the phosphoproteome in unstimulated Tcon of the same donors. In total, we provide phosphoproteomics data of primary human CD4+CD25- T cells from three human healthy donors each for (i) unstimulated Tcons, (ii) 5 minutes TCR-stimulated Tcons, (iii) 5 minutes TCR-stimulated and Treg-suppressed Tcons.

RNA-seq of primary human CD4+ T cells treated with the LXR agonist GW3965, with and without TCR stimulation

Project description:We used RNA-sequencing to determine the transcriptional response to liver X receptor (LXR) activation in primary human CD4+ T cells, both at rest and under activation conditions. CD4+ T cells were isolated from 3 healthy donors and treated with the synthetic LXR agonist GW3965 (GW) for 24 hours. Gene expression was compared to control samples (CTRL) treated with the LXR antagonist GSK1440233. To activate the T cell antigen receptor (TCR), cells were pre-treated with CTRL/GW alone for 6 hours then transferred to plates containing anti-CD3 and anti-CD28 for a further 18 hours.
