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 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.

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.

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.

Assessment of epigenetic variation in human iPS cells Medip

Project description:n order to progress human induced pluripotent stem cells (hiPSCs) towards the clinic, several outstanding questions must be addressed. It is possible to reprogram different somatic cell types into hiPSCs and from studies in the mouse, it appears that an epigenetic memory of the starting cell type is carried over to hiPSCs. However a comprehensive comparative study of the characteristics of these hiPSCs has been missing from the literature. Importantly studies which aimed to address these aspects of hiPSCs have used cells from different patients. In order to avoid this important confounding variable and to keep the genetic background constant, tissue samples were procured from the patients and reprogrammed to iPS cells. The methylation status of these iPS cells will be compared.Protocol:Primary cell cultures were generated and reprogrammed to iPS cells. DNA was extracted and immunoprecipitated using anti-methyl cytosine and anti-hydroxymethyl cytosine antibodies.This data is part of a pre-publication release.

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.
