The regulatory effect of IRF8 on the gene expression profiles of bone marrow derived dendritic cells

ABSTRACT: To investigate the role of IRF8 in the inflammatory microenvironment of abdominal aortic aneurysm tissue, bone marrow cells were isolated from the tibias and femurs of 8-week-old male mice and cultured with granulocyte-macrophage colony-stimulating factor and Flt3L cytokines to generate CD103-positive dendritic cells. Cells were harvested on days 9 and 15-16 and stimulated with tumor necrosis factor-alpha. Gene ontology analysis revealed upregulation of T cell activation and chemotaxis in bone marrow-derived dendritic cells from IRF8 overexpression mice, indicating IRF8's role in dendritic cell-T cell interactions. Protein-protein interaction analysis highlighted Cd40 and Fcgr1 as key surface markers. IRF8-related genes were enriched in type I interferon signaling pathways, implicating IRF8 in antigen presentation functions of dendritic cells.

Gene epxression profiling in murine bone marrow Lin- cells transduced with BCR-ABL and/or IRF8 followed by Flt3L culture for 5 days

Project description:To understand the effect of BCR-ABL and IRF8 on gene expression pattern during in vitro dendritic cell differentiation, microarry analysis was performed. Murine bone marrow Lin- cells were transduced with retroviruses carrying human BCR-ABL cDNA and/or mouse Irf8 cDNA, and then cultured with Flt3L for 5 days. Two independent experiments were performed.

Notch signaling facilitates in vitro generation of cross-presenting classical dendritic cells

Project description:The IRF8-dependent subset of classical dendritic cells (cDC), termed cDC1, is important for cross-priming cytotoxic T cell responses against pathogens and tumors. Culture of hematopoietic progenitors with DC growth factor Flt3 ligand (Flt3L) yields very few cDC1 (in humans) or only immature "cDC1-like" cells (in the mouse). We report that OP9 stromal cells expressing Notch ligand Delta-like 1 (OP9-DL1) optimize Flt3L-driven development of cDC1 from murine immortalized progenitors and primary bone marrow cells. Co-culture with OP9-DL1 induced IRF8-dependent cDC1 with the phenotype (CD103+ Dec205+ CD8α+) and expression profile resembling ex vivo cDC1. OP9-DL1-induced cDC1 showed preferential migration towards Ccr7 ligands in vitro and superior T cell cross-priming and antitumor vaccination in vivo. Co-culture with OP9-DL1 also greatly increased the yield of IRF8-dependent CD141+ cDC1 from human bone marrow progenitors cultured with Flt3L. Thus, Notch signaling optimizes cDC generation in vitro and yields authentic cDC1 for functional studies and therapeutic applications.

Genome wide profiling of active enhancers and IRF8-binding sites in murine mononuclear phagocyte lineage cells

Project description:To understand the mechanism underlying monocyte and dendritic cell development through the regulation of Irf8 expression by the 56 kb downstream (+56 kb) Irf8 enhancer, we performed epigenetic profiling of bone marrow cells and splenocytes from wild-type, the Irf8 +56 kb enhancer-deficient, and IRF8-deficient mice. Taken together with the transcriptome analysis of mononuclear phagocyte lineage cells in these mice, the Irf8 +56 kb enhancer-mediated high Irf8 expression in hematopoietic progenitor cells promote type 1 classical dendritic cell (cDC1) differentiation, while low Irf8 expression in progenitors led to Ly6C+ monocyte development. In addition, IRF8 ChIP-seq of mature cDC1s and monocytes suggested that IRF8 regulates enhancers in cooperation with different transcription factors in each lineage in its expression level.

Comparison of gene expression between wild-type and Osterix1-Cre:Hdac3 CKO BMSC-derived osteoblasts

Project description:Bone marrow stromal cells (BMSC) were isolated from femurs and tibias of littermate wildtype and CKO mice. Cells were plated in osteogenic culture medium (alphaMEM, 20% FBS, 1% antibiotic/antimycotic, 1% non-essential amino acids, 50 ug/mL ascorbic acid, 10 mM beta glycerophosphate, 10^-7 M dexamethasone) and cultured for 7 days prior to RNA isolation.

Quantitative analysis of miRNA changes in bone marrow stem cells under neural differentiation

Project description:Normal SJL mice, 6 to 8 weeks old, were used for the isolation of bone marrow stem cells (BMSC). Bone marrow cells were obtained from the femurs and tibias of euthanized mice by flushing with PBS. Cells were subjected to negative magnetic sorting using the Lineage Cell Depletion Kit. Isolation of murine bone marrow Lin-Sca-1+ cells was performed using MACS Sca-1 MultiSort Kit (fBMSC). The differentiation of neural stem cells was induced by removing the bFGF-containing medium and resuspending cells in fresh bFGF-free medium. Microarray analysis of miRNA expression profiles was performed comparing non differentiated bone marrow stem cells (fBMSC) to bone marrow stem cells differentiated for 4 or 7 days.
