Mitogen-activated protein kinases facilitate many cellular processes and are essential for immune cell function. Their activity is controlled by kinases and dual-specificity phosphatases. A comprehensive microarray analysis of human leukocytes identified DUSP2 (encoding the phosphatase PAC-1) as one of the most highly induced transcripts in activated immune cells. We generated Dusp2(-/-) mice and found considerably reduced inflammatory responses in the 'K/BxN' model of rheumatoid arthritis. PAC- ...[more]

Transcription profiling of mouse bone marrow-derived mast cells were differentiated over 4-6 weeks using bone marrow from Pac-1+/+ and Pac1-/- littermate animals

Project description:Bone marrow-derived mast cells were differentiated over 4-6 weeks using bone marrow from Pac-1+/+ and Pac1-/- littermate mice. Cell purity was 99% c-kit and Fc epsilon receptor positive as assessed by flow cytometry. Cells were stimulated by Fc epsilon receptor crosslinking using IgE-DNP/HSA for sensitization for 18 hours and DNP-HSA antigen for crosslinking for 2 hours. Gene transcript abundance was determined and scaled to 150 using alogorithms in MicroArray Analysis Suite Software 5.0 (Affymetrix). Experiment Overall Design: Two genechips on independent mBMMC cultures was performed. The signal data of the .CEL files for the four Affymetrix 430A chips (2 Pac1+/+ and 2 Pac1â/â) were normalised using the RMA method 49. The ebayes function implemented in the version 1.3.12 of the Limma package (2003) of Bioconductor was used to analyse the data and P-values were adjusted for multiple testing. After conversion from logged values to the original intensities, the data was filtered to remove probe sets with mean, non-logged, intensities below 100. Transcripts with p-values less than 0.05 were considered different from Pac1+/+.

Transcription profiling of mouse IgE/antigen-activated mast cells stimulated with TIM-3

Project description:TIM-3 is known to be expressed on dendritic cells, monocytes, melanoma cells, mast cells and on activated Th1 cells. In activated Th1 cells, stimulating TIM-3 by one of its ligands, galectin-9, leads to apoptosis and thus it plays a central role in terminating Th1-type immune responses. Interestingly, in IgE/antigen-activated mast cells TIM-3 enhances the production of IL-13 and IL-4. To get a more complete picture about the gene expression changes induced by TIM-3 in mast cells, in vitro differentiated mouse immature mast cells were stimulated by an agonist anti-TIM-3 antibody and IgE-sensitized mouse immature mast cells were activated by antigen and an agonist anti-TIM-3 antibody for 2 or 16 hours (overnight). Experiment Overall Design: Bone marrow cells were differentiated in RPMI + 10% FCS + 5 ng/ml mouse IL-3 + 40 ng/ml mouse SCF for >4 weeks. The purity of the cell cultures was >90% at this time point (FcERIa+/c-kit+ cells). These in vitro-differentiated immature mast cells were then treated by either control goat IgG or an agonist anti-mouse TIM-3 antibody (RnD Systems, 15 ug/ml for 2 or 16 hours). For the IgE/antigen-activated mouse mast cells, these in vitro-differentiated immature mast cells were sensitized by 5 ug/ml anti-DNP IgE (Sigma) for 1 hour and then treated with 100 ng/ml DNP-HSA (antigen, Sigma) and either control goat IgG or an agonist anti-mouse TIM-3 antibody (RnD Systems, 15 ug/ml) for 2 or 16 hours. The anti-TIM-3 samples were labeled by Cy5 and they were compared to the Cy3-labeled, goat IgG controls in a dual-color, paired experimental setup. The Agilent Whole Mouse Genome 4x44K expression microarray kit and Dual-Color Protocol version 5.5 were used in the experiments.

Transcription profiling of mouse Pac1+/+ versus Pac1-/- TG-macrophages treated with LPS - 6h

Project description:LPS-stimulated macrophages from Pac1+/+ and Pac1-/- mice were compared to assess gene expression changes in the absence of PAC-1 (also known as Dual specificity phosphatase 2). Experiment Overall Design: Age matched Pac1+/+ and Pac1-/- littermates were used to obtain equal numbers of thiolycollate-elicited macrophages. Pure populations of macrophages were stimulated with 100 ng/ml of LPS for 6 hours. 6 hours was chosen to assess mainly inflammatory gene expression.

Transcription profiling of human major leukocyte types isolated or differentiated and stimulated by LPS, IgE, and PMA from blood to characterise their expression profiles

Project description:WArning Files GSM90663.txt and GSM90665.txt are identical. In the present study we used Affymetrix oligonucleotide microarrays to produce gene transcription profiles for the major leukocyte types in humans. This comprehensive dataset enabled us to not only establish which genes were expressed in each leukocyte type, but also which genes were expressed in each subset after activation. The used of a comprehensive dataset of gene profiles from all the major human leukocyte subsets enabled a novel and powerful means for identification of genes associated with single leukocyte subsets, or different immune paradigms. Experiment Overall Design: Different leukocyte subsets were either isolated or differentiated from human blood to obtain consistently >95% pure populations. Gene profiles for activated effector cells such as macrophages, neutrophils and mast cells were also generated. In most cases, microarray analyses were perform on samples from 2 independent donors.

MAZR and mast cells

Project description:Mast cells are known to be the key players in type I hypersensitivity reactions in humans and mice. They are critically involved in the development of allergic rhinitis, allergic asthma and systemic anaphylaxis. In this study we investigated the role of the transcriptional regulator MAZR in mast cells by comparing the expression profile of mast cells generated from wild-type (MazrF/F) and MAZR-deficient (MazrF/F x Vav-iCre) bone marrow cells. Our results from the array data demonstrate that MAZR acts preferentially as a transcriptional repressor in mast cells.

Mediating effects of miR-155 on the FceRI signaling responses of mast cells

Project description:MicroRNA 155 (miR-155) has been shown to regulate the gene expression of important players of physiological and pathological processes, like hematopoietic lineage differentiation, immunity and inflammation, viral infections, cancer and cardiovascular diseases, among others. Degranulation is an event in which mast cells, upon activation of the FceRI, release their granule content rich in vasoactive amines, proteases and TNFa. Additionally activation of the receptor promotes de novo synthesis of cytokines, chemokines and growth factors. Analysis of bone marrow derived mast cells (BMMC) deficient in miR-155 showed a significant increase in FceRI mediated degranulation and in the release of cytokines like TNFa, IL-6 and IL-13. In addition miR 155-/- mice presented higher anaphylaxis reactions compared to WT mice. Gene expression analysis of BMMC was performed in order to identify intermediaries of FceRI mediated degranulation under the control of miR-155. The results indicate that miR-155 regulates negatively the expression of the regulatory subunits of the kinase PI3Kgamma, Pik3r5 (p101) and Pik3r6 (p84, p87PIKAP), involved in Ca+ influx and degranulation. Total RNA from 3 independent cultures of WT and miR-155-/- BMMC treated with anti-DNP IgE and 20 ng/ml DNP-HSA for 1hr were used to performed gene expression analysis using the Affymetrix GenechipM-BM-.

Exon array analysis of resting and activated primary murine CD4+ T-cells

Project description:The stability, localization and translation of mammalian mRNAs are largely determined by sequences in the 3' untranslated region (UTR). Here, we describe a conserved program of increased upstream polyadenylation site usage following activation of primary murine CD4+ T lymphocytes. This program, resulting in shorter 3' UTRs, is a characteristic of immune cell activation and strongly correlates with proliferation across diverse cell types and tissues. Enforced expression of full-length 3' UTRs confers differences in protein expression that can in some cases be eliminated by deletion of predicted microRNA target sites in the variably included region. Together, our data indicate that polyadenylation site usage is coordinately regulated such that states of increased proliferation are associated with widespread reduction of 3' UTR-based regulation. Keywords: activation, exon array, time course Two or three biological replicates per time point

DIA proteomics of OGG1 inhibition in murine model of fibrosis

Project description:Interstitial lung diseases such as idiopathic pulmonary fibrosis (IPF) are caused by persistent micro-injuries to alveolar epithelial tissues accompanied by aberrant repair processes. Despite substantial advancement in our understanding of IPF progression, numerous questions remain concerning disease pathology. IPF is currently treated with pirfenidone and nintedanib, compounds which slow the rate of disease progression but fail to target underlying pathophysiological mechanisms. The DNA repair enzyme 8-oxoguanine DNA glycosylase-1 (OGG1) is upregulated following TGF-β1 exposure in several fibrosis-associated cell types. Currently, no pharmaceutical solutions targeting OGG1 have been utilized in the treatment of IPF. In this study, administration of Ogg1-targetting siRNA, mitigated bleomycin-induced pulmonary fibrosis in mice, thereby highlighting OGG1 as a tractable target in lung fibrosis. The novel small molecule OGG1 inhibitor, TH5487, decreased myofibroblast transition and associated pro-fibrotic markers in fibroblast cells. In addition, TH5487 decreased pro-inflammatory cytokine production, inflammatory cell infiltration, and lung remodeling in a murine model of bleomycin-induced pulmonary fibrosis. OGG1 and SMAD7 interact to induce fibroblast proliferation and differentiation, with both increased in fibrotic murine and IPF patient lung tissue. Taken together, these data strongly suggest that TH5487 is a potent, specific, and clinically-relevant treatment for IPF. This DIA-MS dataset entails the raw data and peptide-centric DIA-NN search results of both, lung tissue and bronchoalveolar lavage fluid of n=5 mice profiled across the treatment groups bleomycin combined with TH (BTH), dexamethasone (DEX), TH alone (TH) and vehicle control (V) relative to bleomycin alone (B) as control. Different animals within protein groups were considered biological replicates of the respective treatment condition.
