Expression data from CD103+ CD11b+ cDCs expressing or not hBcl-2 transgene in the mesenteric lymph nodes under control chow diet

ABSTRACT: hBcl-2 transgene under CD11c promotor fosters tolerogenic DCs properties linked to a global downmodulation of genes related to pro-inflammatory pathway and upregulation of tolerogenic ones We used microarrays to detail the global programme of gene expression underlying the tolerogenic phenotype of hBcl-2 expressing CD103+ CD11b+ cDCs to identify the pathways involved in the promotion of tolerogenic DCs ability

Carvacrol treated Dentritic Cells

Project description:Tolerogenic dendritic cells (DCs) induce regulatory T-cells and dampen pathogenic T-cell responses. Hereby, they have gained interest as a therapeutic target in the combat against autoimmune diseases. In this study we investigated whether tolerogenic DCs are induced by the phytonutrient carvacrol, a molecule with known anti-inflammatory properties. In this study, bone marrow derived DCs were treated with carvacrol in combination with thermal stress. Gene expression profiles were obtained by microarray analysis to test for an induced tolerogenic phenotype. To investigate the tolerogenic properties of treated DCs in vivo, T-cell anergy or the induction of a regulatory T-cell phenotype was studied in antigen specific T-cells. Finally, treated DCs were tested by transfer into an experimental arthritis model.

Induced CD103+ Dendritic Cells

Project description:Multiple subsets of FLT3L-dependent dendritic cells (DCs) control T cell tolerance and immunity. In mouse tissues, CD8α-like DCs are identified by CD103 expression. This DC subset efficiently enters lymph nodes and cross-presents antigens, rendering CD103+ DCs promising targets for therapeutic tolerance induction or vaccination. However, only limited numbers of CD103+ DCs can be isolated with current methods. Moreover, bone marrow cultures with FLT3L produce complex mixtures of DC subsets. We developed a novel method for generating large numbers of Batf3-dependent CD103+ DCs. We used microarray analysis to compare in vitro generated CD103+ and CD103- DCs and correlated their expression patterns to published profiles and signatures of DC subsets.

Transcription profiling by array of human dendritic cells exposed to mesenchymal stem cells

Project description:All experiments are performed on human dendritic cells (DCs) differentiated in GM-CSF and IL-4 from CD14+ cells and bone marrow mesenchimal stem cells (MSCs). We found that MSCs impair active immune synapse formation and we evidenced at electron microscopy two types of contact between MSCs and DCs: gap and adherent junctions. In the same experiments we show that MSC contacts induce a reorganization of DC cytoskeleton by the formation of actin podosomes, structures typical of an immature, tolerogenic state of DCs. These results suggest that MSCs exert a tolerogenic effect on DCs by mechanism mediated by cell-cell contact. This induces DC cytoskeleton reorganization with formation of actin podosomes.

Mertk negatively regulates adaptive immunity

Project description:Tolerogenic dendritic cells (tol-DCs) offer a promising therapeutic potential for autoimmune diseases. Tol-DCs have been reported to inhibit immunogenic responses, yet little is known about the mechanisms controlling their tolerogenic status, as well as associated specific markers. Here we show that the anti-inflammatory TAM receptor tyrosine kinase MERTK, is highly expressed on clinical grade dexamethasone-induced human tol-DCs and mediates their tolerogenic effect. Neutralization of MERTK in allogenic mixed lymphocyte reactions as well as autologous DC-T cell cultures leads to increased T cell proliferation and IFN-g production. Additionally, we identify a previously unrecognized non-cell autonomous regulatory function of MERTK expressed on DCs. Recombinant Mer-Fc protein, used to mimic MERTK on DCs, suppresses naïve and antigen-specific memory T cell activation. This mechanism is mediated by the neutralization of the MERTK agonist Protein S (PROS1) expressed by T cells. We find that MERTK and PROS1 are expressed in human T cells upon TCR activation and drive an autocrine pro-proliferative mechanism. Collectively, these results suggest that MERTK on tol-DCs directly inhibits T cell activation through the competition for PROS1 interaction with MERTK in the T cells. Targeting MERTK may provide an interesting approach to effectively increase or suppress tolerance for the purpose of immunotherapy. The complete database comprised the expression measurements of 54,675 genes for: immature (n=9), mature (n=7) and tolerogenic (n=8). Influence of treatment with dexamethasone (n=3) and LPS (n=2) are included.

Nuclear Receptor Co-repressor NCoR1 governs immune-tolerance in conventional dendritic cells by fine-tuning glycolysis and fatty acid oxidation

Project description:In this study, we focused on demonstrating the metabolic aspect of NCoR1 in the regulation of dendritic cells (DCs) functionality. We report that NCoR1 deficient tolerogenic DCs meet their anabolic requirements through enhanced glycolysis and OxPhos, supported by FAO-driven oxygen consumption. Furthermore, individual and dual inhibition of glycolysis through HIF-1α inhibitor (KC7F2) and fatty acid oxidation through CPT1 inhibitor (etomoxir) significantly impaired the secretion of tolerogenic cytokines. To validate the same at the global mRNA level we did bulk RNA-seq to determine the differentially expressed genes in control and NCoR1 KD 6h CpG activated DCs with and without inhibitor treatment.

Transcriptomes of monocyte-derives DCs stimulated with various compounds

Project description:Little is known about the early transcriptional events in innate immune signaling in immature and tolerogenic monocyte-derived dendritic cells (DCs), the professional antigen-presenting cells of our immune system. TLR ligands usually induce a proinflammatory transcriptional response, whereas IL10 and/or dexamethasone induce a more tolerogenic phenotype. We used Affymetrix microarrays to obtain detailed information underlying pro- and anti-inflammatory transcriptional responsesand transcriptional networks in DCs A pilot experiment was performed in which monocyte-derived DCs were either treated with TLR4 ligand LPS, or IL10 and dexamethason. Furthermore, IL10/dexamethason treated cells were also stimulated with LPS for an additional 6 hr. All samples were then subjected to global gene expression analysis using Affymetrix technology.
