Arc/Arg3.1 functionally defines migrating 1 dendritic cells and regulates actin dynamics

ABSTRACT: We compared the expression profiles of bone marrow-derived dendritic cells (BMDC) derived from Arc/Arg3.1 knockout and wildtype animals. We generated bone marrow-derived dendritic cells (BMDC) from Arc/Arg3.1 knockout and wildtype animals. BMDC were either stimulated with LPS or left untreated and analysed by microarray.

Transcription profiling of mouse bone marrow-derived dendritic cells (BMDC), with cells that had been cocultured (1:5, tumor:BMDC) with mouse ovarian surface epithelial cell line (1D8) cells, with irradiated (50Gy) 1D8 cells, or with the supernatent from 1D8 cells (25%, v/v)

Project description:The Suppressor of cytokine signaling (SOCS) family of negative regulatory proteins are upregulated in response to several cytokines and pathogen-associated molecular patterns (PAMPs), and suppress cellular signaling responses by binding receptor phosphotyrosine residues. Exposure of bone marrow-derived dendritic cells (BMDCs) to 1D8 cells, a murine model of ovarian carcinoma, suppresses their ability to express CD40 and stimulate antigen specific responses in response to PAMPs, and in particular to poly I: C with the upregulated SOCS3 transcript and protein levels. The ectopic expression of SOCS3 in both the macrophage cell line RAW264.7 and BMDCs decreased signaling in response to both poly I:C and IFNÎ±. Further, knockdown of SOCS3 transcripts significantly enhanced the responses of RAW264.7 and BMDCs to both poly I: C and IFNÎ±. Immunoprecipitation and pull-down studies demonstrate that SOCS3 binds to the IFNÎ± receptor TYK2. Since poly I: C triggers autocrine IFNÎ± signaling, binding of SOCS3 to TYK2 may thereby suppress the activation of BMDCs by polyI:C and IFNÎ±. Thus, elevated levels of SOCS3 in tumor-associated DCs may potentially resist the signals induced by TLR3 ligands and type I interferon to decrease DC activation via binding with IFNÎ± receptor TyK2. Experiment Overall Design: Microarray analysis was used to compare the expression levels of Control mouse bone marrow-derived dendritic cells (BMDC), with cells that had been cocultured (1:5, tumor:BMDC) with mouse ovarian surface epithelial cell line (1D8) cells, with irradiated (50Gy) 1D8 cells, or with the supernatent from 1D8 cells (25%, v/v). Experiment Overall Design: One biologic sample was analyzed for each condition, four samples in all.

Gene expression profiling to identify genes that are differentially expressed between murine MHCIIlo and MHCIIhi dendritic cell subpopulations [MHCIIhi vs. MHCIIlo]

Project description:Hematopoietic progenitors from mouse bone marrow were differentiated into dendritic cells for 5 days with GM-CSF and IL-4. On day 6, MHCIIhi and MHCIIlo BMDC subpopulations were sorted to purify by flow cytometry. RNA was extracted and processed for microarray analysis. Two condition experiment; Biological replicates: 4 replicates per condition.

Comparison of gene expression profiles in naïve WT and Asc-null bone marrow derived dendritic cells

Project description:The adaptor protein ASC contributes to innate immunity through the assembly of caspase-1-activating inflammasome complexes. We demonstrate that ASC plays an inflammasome-independent cell-intrinsic role in adaptive immune cells. Asc-/- mice displayed defective antigen presentation by dendritic cells and lymphocyte migration due to impaired Rac-mediated actin polymerization. Genome-wide analysis showed that ASC, but not Nlrp3 or caspase-1, controls mRNA stability and expression of DOCK2, a guanine nucleotide exchange factor that mediates Rac-dependent signaling in immune cells. DOCK2-deficient dendritic cells showed similar defective antigen uptake as Asc-/- cells. Ectopic expression of DOCK2 in ASC-deficient cells restored Rac-mediated actin polymerization, antigen uptake and chemotaxis. Thus, ASC shapes adaptive immunity independently of inflammasomes by modulating DOCK2-dependent Rac activation and F-actin polymerization in dendritic cells and lymphocytes. Three replicates of naïve WT and three replicates of Asc-/- bone marrow derived dendritic cells were analyzed on the Affymetrix HT MG-430 PM plate array.

Expression data of colony-stimulating factor (CSF) grown bone marrow derived cells

Project description:Granulocyte-Macrophage colony stimulating factor (GM-CSF) devlops heterogenous myeloid cell populations from bone marrow progenitor cells. In vitro generated bone marrow derived cells are excellent sources for obtaining dendritic cells or macrophages, but it is still not clear about the exact mixed population characteristics of GM-CSF grown cells. We revealed here that GM-CSF grown bone marrow cell derived attaching cells were composed of dendritic cells (GM-BMDC) as well as macrophages (GM-BMM). We compared the transcriptome profiles of these cell populations as well as M-CSF grown bone marrow derived macrophages (M-BMM). We used microarrays to detail the global profile of gene expressions between three populations of CSF-grown bone marrow derived cells: GM-CSF derived dendritic cells (GM-BMDC), GM-CSF derived macrophages (GM-BMM) and M-CSF derived macrophages (M-BMM). Bone marrow cells were differentiated for 7 days with 25 ng/ml GM-CSF or 20% L cell conditioned media as a M-CSF supplier. GM-BMDCs were sorted from MHCIIhighF4/80low population and GM-BMMs were sorted in the MHCIIlowF4/80high population. M-BMMs were sorted from CD11b+F4/80+ population.

A dominant role for the methyl-CpG-binding protein Mbd2 in controlling Th2 induction by dendritic cells [gene expression]

Project description:Dendritic cells (DCs) direct CD4+ T cell differentiation into distinct T helper (Th) subsets that are vital for protection against diverse types of infection. However, the mechanisms employed by DCs to initiate Th2 responses, which are important for immunity to helminth infection as well as being a major contributor to allergic disease, remain poorly understood. We demonstrate a crucial role for methyl-CpG-binding domain-2 (Mbd2), a protein that links DNA methylation to repressive chromatin structure, in regulating DC gene expression and ability to promote Th2 immunity against either helminths or allergens. RNAs were extracted from murine (C57BL/6) Bone marrow-derived dendritic cells (BMDC) samples. Two groups of samples (three replicates each) were processed: (1) wild type, and (2) a homozygous knock-out of the Mbd2 locus.

Project description:Analysis of baseline gene expression in bone marrow derived dendritic cells (BMDC) from female CBA/J (CBA) and C57BL/6 (BL/6) mice. Results provide insight into strain-dependent differences in gene expression. CBA and BL/6 BMDCs prepared from individual mice were plated in replicate at 1x10^6 cells/ml in 48-well tissue culture plates (BD Falcon). Replicates were pooled after 4hr and total RNA was obtained by TrizolM-BM-. (Invitrogen) extraction according to the manufacturerM-bM-^@M-^Ys instructions.

Gene expression data in Bone Marrow Derived Dendritic Cells (BMDC) following nanoemulsion adjuvant exposure

Project description:Antigen uptake, processing and presentation by dendritic cells are regulated by complex intra- and inter-cellular signalling events. Typical vaccine adjuvants lead to the transcription of pro-inflammatory cytokines and chemokines which relate to immune induction. We used microarrays to detail the global expression of genes in BMDC underlying emulsion internalization and DC activation with a non-inflammatory nanoemulsion adjuvant. BMDC were incubated with 0.001% v/v naomeulsion (W805EC) or media alone for 6 hours. Total RNA was extracted per sample using RNA easy (Qiagen).
