Project description:Activated Foxp3+ regulatory T cells (Tregs) express several TNF receptor superfamily (TNFRSF) members. Here, we analyzed the transcriptome of purified Tregs that were activated with anti-CD3 and anti-CD28 mAbs, IL-2 and with or without agonists of TNFR2, 4-1BB, DR3 and OX40 for 18h and 36h. Triggering these TNFRSF in Tregs induces similar changes in gene expression patterns, suggesting that they engage common signal transduction pathways. Among them, we identified a major role of canonical NF-κB.

Project description:CD4+Foxp3+ regulatory T cells (Treg) are a subpopulation of T cells, which regulate the immune system and enhance immune tolerance after transplantation. Donor-derived Treg prevent the development of lethal acute graft and host disease (GVHD) in murine models of allogeneic hematopoietic cell transplantation. It was reported that a single treatment of the agonistic antibody to Death receptor 3 (DR3) in donor mice resulted in the expansion of donor derived Treg and prevented acute GVHD, although the precise role of DR3 signaling in GVHD has not been elucidated. We analyzed the gene expression profile, immune phenotype, and function of DR3-activated Treg in a murine model of allogeneic hematopoietic cell transplantation. CD4+Foxp3+ Treg were sorted from the mice stimulated with anti-DR3 or control antibody using fluorescence-activated cell sorter for RNA extraction and hybridization on Affymetrix microarrays.

Project description:Disturbances in glucose homeostasis and low-grade chronic inflammation culminate into metabolic syndrome that increase the risk for the development of type 2 diabetes mellitus (T2DM). The recently discovered type 2 innate lymphoid cells (ILC2s) are capable of secreting copious amounts of type 2 cytokines to modulate metabolic homeostasis in adipose tissue. In this study, we have established that expression of Death Receptor 3 (DR3), a member of the TNF superfamily, on visceral adipose tissue (VAT)-derived murine and peripheral blood human ILC2s is inducible by IL-33. We demonstrate that DR3 engages the canonical and/or non-canonical NF-B pathways, and thus stimulates naïve and co-stimulates IL-33-activated ILC2s. Importantly, DR3 engagement on ILC2s significantly ameliorates glucose tolerance, protects against insulin-resistance onset and remarkably reverses already established insulin-resistance. Taken together, these results convey the potent role of DR3 as an ILC2 regulator and introduce DR3 agonistic treatment as a novel therapeutic avenue for treating T2DM.

Project description:To explore the effect of human MHC haplotype on gene expression phenotype across the MHC, we examine the MHC transcriptomic landscape at the haplotype-specific resolution for three prominent MHC haplotypes (A2-B46-DR9, A33-B58-DR3 and A1-B8-DR3) derived from the RNA-sequencing of MHC-homozygous B-LCLs. We demonstrate that MHC-wide gene expression pattern is dictated by the underlying MHC haplotype and identify 37 differentially expressed genes among the haplotypes.

Project description:T2 cells stably expressing HLA-DR3 and variable amounts of HLA-DM (none, low, and high, per GFP co-expression) were lysed and HLA-DR3-peptide complexes were isolated via immunoprecipitation. Antigenic peptides were then eluted and quantified by LC-MS/MS to assess presented antigenic epitopes.

Project description:The genome-wide analysis of the binding sites of the transcription factor vitamin D receptor (VDR) is essential for a global appreciation the physiological impact of the nuclear hormone 1M-NM-1,25-dihydroxyvitamin D3 (1,25(OH)2D3). Genome-wide analysis of lipopolysaccharide (LPS)-polarized THP-1 human monocytic leukemia cells via chromatin immunoprecipitation (ChIP) coupled with massive parallel sequencing (ChIP-seq) resulted in 1,318 high-confidence VDR binding sites, of which 789 and 364 occurred uniquely with and without 1,25(OH)2D3 stimulation, while only 165 were common. We re-analyzed five public VDR ChIP-seq datasets with identical peak calling settings (MACS, version 2) and found in total 23,409 non-overlapping VDR binding sites, 75% of which are unique within the six analyzed cellular models. LPS-differentiated THP-1 cells have 22% more genomic VDR locations than undifferentiated cells and both cell types display more overlap in their VDR locations than the other investigated cell types. In general, the intersection of VDR binding profiles of ligand-stimulated cells is higher than those of unstimulated cells. De novo binding site searches and DR3-type binding site screening using HOMER of the six VDR ChIP-seq datasets suggest that DR3 sites are strongly associated with the ligand-responsiveness of VDR occupation. Importantly, all VDR ChIP-seq datasets display the same relationship between the VDR occupancy and the percentage of DR3-type sequences below the peak summits. The comparative analysis of six VDR ChIP-seq datasets demonstrated that the mechanistic basis for the action of the VDR is independent of the cell type. Only the minority of genome-wide VDR binding sites contains a DR3-type sequence. Moreover, the total number of identified VDR binding sites in each ligand-stimulated cell line inversely correlates with the percentage of peak summits with DR3 sites. Systematic reanalysis of 5 published VDR ChIP-seq datasets together with a new dataset from 24 h LPS-treated THP-1 cells at the unstimulated state and after 80 min ligand (10 nM 1M-NM-1,25(OH)2D3 (1,25D, calcitriol)) treatment.

Project description:Donminant negative transform growth factor receptor II (DNR) mice were served as a murine primary biliary cirrhrosis model. CD4+Foxp3+ Regulatory T cells (Tregs) play a critical role in self-tolerance and in regulating PBC. In order to determine whether DNR mice derived Tregs processed defective function compared with WT Tregs, CD4+Foxp3+ Treg cells were sorted from DNR and WT mice, respectively, then gene expression analysis was performed by using the Affymetrix GeneChip Mouse Genome 430 2.0 arrays CD4+Foxp3+ Tregs were sorted from the spleen of 10-week-old DNR mice and B6 wild-type mice, respectively. RNA of each sample was then extracted and hybridized on Affymetrix microarrays to detail differences between DNR Tregs and WT Tregs in gene expression.

Project description:Analysis of acute effects of ligand-treatment on vitamin D receptor binding genome-wide using ChIP-seq. THP-1 monocytic leucemia cells were treated with 1?,25(OH)2D3 (1,25D) or left unstimulated to investigate the acute effects of VDR chromatin occupancy. We identified in total 2340 VDR binding sites with and without the ligand. Without the ligand, there is a considerable presence of VDR already on the chromatin. However, upon a short (40 min) ligand treatment VDR shifts from sites that rarely contain a DR3 type element to sites that frequently contain one or more DR3-type element. Genome-wide identification of VDR binding in THP-1 cells at the unstimulated state and after 40 min ligand (10 nM 1?,25(OH)2D3 (1,25D, calcitriol)) treatment.
