Project description:EBV-encoded proteins interfere with extrinsic and intrinsic apoptotic pathways so that homeostasis of infected cells shifts to survival and proliferation favoring to evasion of virus from immune surveillance.The aim of investigation is to reveal the key factors regulating Fas- и DR3-triggered cascades influenced by EBV in naïve T-cells. We developed the splicing-sensitive microarray covering 221 genes encoding apoptosis-associated factors, adaptor proteins, kinases, RNA-binding proteins (including spliceosome elements) etc. Naïve CD4+ and CD8+ T-cells isolated from the same EBV-infected patient during acute mononucleosis and after therapy were analyzed.

Project description:TNF-like ligand 1A (TL1A) is a member of TNF receptor superfamily and involved in the pathogenesis of autoimmune diseases by inducing apoptosis via intracellular death domain or promoting inflammation through the activation of NFκB by binding to its specific receptor death receptor 3 (DR3). Meanwhile, decoy receptor 3 (DcR3) competitively binds soluble TL1A in addition to Fas-ligand (FasL) and LIGHT and inhibits the signaling of TL1A via DR3. DcR3 overexpressed in rheumatoid synovial fibroblasts (RA-FLS) stimulated with inflammatory cytokines such as TNFα or IL-1β inhibits Fas-induced apoptosis. In contrast, DcR3 inhibited cell proliferation induced by inflammatory cytokines via membrane-bound TL1A expressed on RA-FLS. Therefore, TL1A-DcR3/DR3 signaling may be involved in the pathogenesis of RA by modulating apoptosis and proliferation of RA-FLS. We hypothesized that TL1A regulates the gene expression in RA-FLS. We used to search for genes in which expression in RA-FLS is regulated by the ligation of TL1A.

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:TNF-like ligand 1A (TL1A) is a member of TNF receptor superfamily and involved in the pathogenesis of autoimmune diseases by inducing apoptosis via intracellular death domain or promoting inflammation through the activation of NFM-NM-:B by binding to its specific receptor death receptor 3 (DR3). Meanwhile, decoy receptor 3 (DcR3) competitively binds soluble TL1A in addition to Fas-ligand (FasL) and LIGHT and inhibits the signaling of TL1A via DR3. DcR3 overexpressed in rheumatoid synovial fibroblasts (RA-FLS) stimulated with inflammatory cytokines such as TNFM-NM-1 or IL-1M-NM-2 inhibits Fas-induced apoptosis. In contrast, DcR3 inhibited cell proliferation induced by inflammatory cytokines via membrane-bound TL1A expressed on RA-FLS. Therefore, TL1A-DcR3/DR3 signaling may be involved in the pathogenesis of RA by modulating apoptosis and proliferation of RA-FLS. We hypothesized that TL1A regulates the gene expression in RA-FLS. We used to search for genes in which expression in RA-FLS is regulated by the ligation of TL1A. RA-FLS were obtained from 4 RA patients (sample1-4). Each sample was incubated with either 1.0 M-NM-<g/ml recombinant human TL1A protein or phosphate buffered saline (PBS) diluted with serum-free Opti-MEM medium as non-stimulated control for 12 hours at 37M-BM-0C with 5% CO2. Gene expression in RA-FLS stimulated by TL1A was compared with that of their respective non-stimulated controls.

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:Affymetrix HuGene ST 1.0 microarrays were used to study and compare gene expression in peripheral blood CD8+ T cells of human patients with Acute Infectious Mononucleosis (AIM; acute EBV infection) and during convalescence (CONV; 6-12 months after AIM visit). Blood samples were drawn from ten human patients with AIM and again during their covalescence (CONV). Peripheral blood mononuclear cells were isolated and cryopreserved. Paired AIM and CONV samples were thawed and CD8+ T cells purified with magnetic beads. RNA was isolated and processed for hybridization according to the Affymetrix protocol CD8+ T cells acute and convalescent phase of EBV infection (10 subjects)

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.
