Genome wide mapping of NFAT1 binding sites in dendritic cells and of chromatin state in steady and dectin-1 activated dendritic cell line D1

ABSTRACT: We generated genome-wide chromatin-state maps of mouse dendritic cells in steady and dectin-1 activated with or without NFAT inhibitor FK506. We found the differential H3K4me3 signatures in these cells. This study provides the epigenetic signatures of steady, dectin-1activated with or without NFAT inhibition. We also generated stable dendritic cell line D1 expressing a V5 tagging NFAT1. This cell line was used to map the global binding sites of NFAT1 upon dectin-1 activation with 10ug/ml curdlan for 30 minutes. examine NFAT1-v5 genome wide binding sites and differential H3K4me3 epigenetic modification in steady, dectinn-1 activated with or without NFAT inhibiton.

The transcription factor NFATc2 regulates dendritic cell (DC) responses to microbial stimulation through the C-type lectin receptor dectin-1. But the genetic targets of NFATc2 and their effects on DC function remain largely unknown. Therefore we used ChIP-seq to conduct genome-wide mapping of NFATc2 target sites in dectin-1-activated DCs. By combining binding-site data with a comprehensive gene expression profile, we found that NFATc2 occupancy regulates the expression of a subset of dectin-1-ac ...[more]

Gene expression profiling of dectin-1 and NFAT responsive genes in dendritic cells

Project description:This study provides the dectin-1 and NFAT responsive genes for 2h and 4h of curdlan treatment. Affymetrix Mouse Gene 1.0ST Arrays were used to profile gene expression in curdlan-stimulated D1 cells (2h or 4h exposure) that had been treated or not with FK506 for the duration of culture. Dendritic cell line D1 was treated with curdlan for 2h and 4h, and curdlan + Fk506 for 2h and 4h in three replicate.

Transcription profiling of mouse MyD88-deficient bone marrow-derived macrophages treated with Zymosan

Project description:Innate immune pattern recognition receptors play critical roles in pathogen detection and initiation of antimicrobial responses. We and others have previously demonstrated the importance of the beta-glucan receptor Dectin-1 in the recognition of pathogenic fungi by macrophages and dendritic cells, and have elucidated some of the mechanisms by which Dectin-1 signals to coordinate the antifungal response. While Dectin-1 signals alone are sufficient to trigger phagocytosis and Src-Syk-mediated induction of antimicrobial reactive oxygen species, collaboration with Toll-like receptor (TLR)2 signaling enhances NF-kB activation and regulates cytokine production. In this study we demonstrate that Dectin-1 signaling can also directly modulate gene expression via activation of nuclear transcription of activated T cells (NFAT) transcription factors. Dectin-1 ligation by zymosan particles or live Candida albicans yeast triggers NFAT activation in macrophages and dendritic cells. Dectin-1-triggered NFAT activation plays a role in the induction of Egr2 and Egr3 transcription factors, and cyclooxygenase 2 (Cox-2). Furthermore, we show that NFAT activation regulates IL-2, IL-10 and IL-12 p70 production by zymosan-stimulated dendritic cells. These data establish NFAT activation in myeloid cells as a novel mechanism of regulation of the innate antimicrobial response. Experiment Overall Design: Bone marrow-derived macrophages deficient in MyD88 were stimulated with zymosan, and total RNA was extracted 120 minutes after stimulation for comparison to macrophages grown under the same conditions, but not stimulated.

Impaired calcineurin signaling in dendritic cells and macrophages increases susceptibility to aspergillosis through pentraxin-3 downregulation

Project description:Treatment of post-transplant patients with immunosuppressive drugs targeting the calcineurin-NFAT pathway, such as Cyclosporine A or Tacrolimus, are commonly associated with a higher incidence of opportunistic infections, such as Aspergillus fumigatus, which can lead to severe life-threating conditions. A component of the A. fumigatus cell wall, β-glucan, is recognized by dendritic cells via the Dectin-1 receptor, triggering downstream signaling that leads to calcineurin-NFAT binding, NFAT translocation, and transcription of NFAT-regulated genes. Here, we address the question of whether calcineurin signaling in CD11c-expressing cells, such as DCs, has a specific role in the innate control of A. fumigatus. Impairment of calcineurin in CD11c-expressing cells (CD11ccrecnb1loxP) significantly increased susceptibility to systemic A. fumigatus infection and to intranasal infection in irradiated mice undergoing bone marrow transplant. Global expression profiling of bone marrow-derived DCs identified calcineurin-regulated processes in the immune response to infection, including expression of pentraxin-3, an important anti-fungal defense protein. These results suggest that calcineurin inhibition directly impairs important immunoprotective functions of myeloid cells, as shown by the higher susceptibility of CD11ccrecnbloxP mice in models of systemic and invasive pulmonary aspergillosis, including after allogeneic bone marrow transplantation. These findings are relevant to the clinical management of transplant patients with severe Aspergillus infections.
