MiRNA expression in Blimp-1-deficient dendritic cells

ABSTRACT: Expression of Blimp-1 was specifically deleted in dendritic cells (DCs) by breeding Blimp-1 flox and CD11c-CRE mice. MiRNA expression was evaluated and compared from DCs, CD4+ T cells and total B cells from spleens of control and Blimp-1 KO mice. Age-matched (6-10 weeks old) female mice from control and Blimp-1 KO mice were sacrificed and spleens were collected. CD11chi/MHCIIhi DCs, CD4+TCRb+ T cells and B220+ B cells were sorted by FACSaria. MiRNA was measured from the total RNA preparation.

Gene expression profiling of mouse splenic Dendritic cells subsets

Project description:We describe a novel subset of CD8+ DCs in lymphoid organs of naïve mice characterized by expression of the CX3CR1 chemokine receptor. CX3CR1+CD8+ DCs lack hallmarks of classical CD8+ DCs, including IL12 secretion, the capacity to cross-present antigen and their developmental independence of the transcriptional factor BatF3. Gene expression profiling showed that CX3CR1+CD8+ DCs resemble CD8- cDCs. The microarray analysis further revealed a unique plasmacytoid DC (PDC) gene signature of CX3CR1+ CD8+ DCs. A PDC relationship of the cells is further supported by the fact that they harbor characteristic D-J immunoglobulin gene rearrangements and that development of CX3CR1+CD8+ DCs requires E2-2, the critical transcriptional regulator of PDCs. Thus, CX3CR1+ CD8+ DCs represent a unique DC subset, related to but distinct from PDCs. After collagenase D digestion, spleens from Cx3cr1gfp/+ C57BL/6 mice were enriched for CD11c+ cells by magnetic separation according to the manufacturer’s protocol (MiltenyiBiotec GmbH). Splenic CD11chi cells were isolated using the FACS ARIA high-speed sorter (Becton-Dickinson). Total RNA was extracted and subjected to gene expression profiling using the Mouse Genome 430.2 Affymetrix GeneChip

Project description:To investigate the gene expression in dendritic cells after treating hemiphilic mice with HBSS, plasma derived or recombinant factor VIII Gene expression in dendritic cells were measured 24 hours post treatment Hemophilic mice with treated with either (HBSS, rFVIII or pdFVIII) 24 hours post treatment the spleens were isolated and CD11+ DCs were purified. The gene expression in the DCs were then investigated by microarray studies.

Expression data in splenic DC subsets in wild type and Xbp1 deficient mice

Project description:Xbp1 is a major transcription factor in the unfolded protein response. To uncover its function in DCs we generated a conditional KO for Xbp1 in dendritic cells. We here compare the expression of mRNAs in two different splenic DC subpopulations, CD8a and CD11b DCs in both WT and KO mice. Reference: Inositol-requiring enzyme 1-alpha regulates CD8a dendritic cell function via regulated mRNA decay. Osorio et al, Nature Immunology (2014) Primary DC subsets were isolated and sorted from spleens from 3 different WT or CD11c-cre Xbp-1fl/fl mice. RNA was isolated, converted to cDNA and then hybridised on Affymetrix GeneChip Mouse Gene 1.0 ST Arrays (GPL6246).

C5aR+ lysozyme-expressing dendritic cells (LysoDCs) comprise a unique cell population in the Peyer’s patch (PP) subepithelial dome (SED).

Project description:CD11chi cells can be subdivided into six different cell subsets:plasmacytoid DCs (pDCs), CD8a+ DCs, CD11b+ DCs, double-negative (DN) DCs, LysoDCs, and LysoMacs. Among these, LysoDC (CD4–) and LysoMacs (CD4+) are classified as CD11chiMHC class II+BST2intSIRPαhi lysozyme+ cells, depending on whether they express CD4. Here, we determine that C5aR expressed in LysoDC and LysoMacs. We used microarrays to determine the lineage of C5aR+ LysoDC and C5aR- LysoDC.

Transcriptional profile of WT, PRR and IFN-/- dendritic cells stimulated with poly IC in vivo

Project description:Analysis of the specific transcriptional changes on DCs provided by direct pattern recogition receptor (PRR) or IFNAR signaling that are required for DC maturation after poly IC stimulation. Results provide important information about the intricate differentiation process of DC maturation and the importance of type I IFNs for DC immunogenicity. WT/IFNA-/- or WT/PRR-/- mixed-chimera mice were injected with 50 ug Poly-IC i.p. in vivo 4 and 14 hr later, wild type and KO CD11chi CD3- DX5- B220- DCs were FACS sorted based on CD45.2 expression. Total RNA was isolated and expression profile was compared between unstimulated and activated WT and KO DCs.

Transcription profiling of mouse dendritic cells from the spleens of Alymphoplasia or heterozygeous littlermates (wild type) to identify TNIK/NF-kappaB2 regulated gene products.

Project description:This study aims at identifying genes that are NIK/NF-kappaB2 responsive in murine dendritic cells matured in vivo. Experiment Overall Design: This study isolated dendritic cells from the spleens of Alymphoplasia or heterozygeous littlermates (wild type). Mice were eiter not treated as a reference or treated I.P. with 25 micrograms of LPS and 100 micrograms of agonistic anti-CD40 antibody. DCs were isolated 6 hours after treatment allowing in vivo maturation via both TLR and CD40 signals. DCs from 3 mice per group were pooled. Experiment was performed in triplicate.

Epigenetic modifications induced by Blimp-1 regulate CD8+ T cell memory progression during acute virus infection

Project description:Blimp-1 regulates the overall accumulation of virus-specific CD8+ T cells during acute viral infections. Increased proliferation and survival of Blimp-1-deficient CD8+ T cells is promoted by persistent cytokine responsiveness, resulting from sustained expression of CD25 and CD27. Knockdown of these genes reduced the Blimp-1-deficient CD8+ T cell response. Genome-wide ChIP-sequencing analysis identified CD25 and CD27 genes as direct targets of Blimp-1. At the peak of the anti-viral response, but not earlier, Blimp-1 recruited the histone modifying enzymes G9a and HDAC2 to the Il2ra and Cd27 loci, thereby repressing expression of these genes. In the absence of Blimp-1, the Il2ra and Cd27 genes exhibited enhanced histone H3-acetylation and reduced histone H3K9-trimethylation. These data elucidate a central mechanism by which Blimp-1 acts as an epigenetic regulator, enhancing the numbers of short-lived effector cells while suppressing the development of memory precursor CD8+ T cells. NaM-CM-/ve CD8+ T cells from OT-I TCR transgenic Rag1-/- mice were stimulated with anti-CD3 and anti-CD28 for three days in vitro, in the presence of IL-2 to up-regulate Blimp-1 protein. Genome-wide mapping of Blimp-1 binding in mouse CD8+ T cells was conducted.

Interleukin-23-induced transcription factor Blimp1 promotes pathogenicity of T helper 17 cells

Project description:Interleukin-23 (IL-23) is a pro-inflammatory cytokine required for the pathogenicity of T helper 17 (Th17) cells but the molecular mechanisms governing this process remain unclear. We identified the transcription factor Blimp-1 (Prdm1) as a key IL-23-induced factor that drove the inflammatory function of Th17 cells. In contrast to thymic deletion of Blimp-1, which causes T cell development defects and spontaneous autoimmunity, peripheral deletion of this transcription factor resulted in reduced Th17 activation and reduced severity of autoimmune encephalomyelitis. Furthermore, genome wide occupancy and overexpression studies in Th17 cells revealed that Blimp-1 co-localized with transcription factors RORÎ³t, STAT-3 and p300 at the Il23r, Il17a/f and Csf2 cytokine loci to enhance their expression. Blimp-1 also directly bound to and repressed cytokine loci Il2 and Bcl6. Taken together, our results demonstrate that Blimp-1 is an essential transcription factor downstream of IL-23 that acts in concert with RORÎ³t to activate the Th17 inflammatory program. Genome-wide binding analysis of Blimp1 from in vitro generated T effector and regulatory cells
