RNA Sequencing Analysis of Mouse Bone Marrow Derived Dendritic Cells Transcriptomes During Maturation

ABSTRACT: Purpose:The purpose of this study is to detect activated or silenced genes during LPS-induced dendritic cell maturation. Gene expression differences between two samples could be found using transcriptome profiling (RNA-seq) analysis. Methods:Mouse dendritic cells were generated from bone marrow cells in RPMI-1640 medium with recombinant mouse GM-CSF and IL-4, mature DCs were obtained after LPS induced maturation. Immature DCs and mature DCs were sorted respectively based on maturation marker CD86 and Iab(MHCII) using flowcytrometer. DC mRNA profiles were generated by deep sequencing,using Illumina Results: We mapped about 10 million sequence reads per sample to the mouse genome, identified 1,300 upregulated genes and 1,475 dow regulated genes during dendritic cell maturation. DC mRNA profiles immature and mature moouse BMDCs were generated by deep sequencing

Histone modifications play critical roles in the regulation of gene expression; however, their roles in the regulation of the innate response remain to be fully investigated. Using transcriptome analysis of mouse immature dendritic cells (DCs) and LPS-induced mature DCs, we identified that Ezh1 was the most upregulated histone methyltransferase during DC maturation. In this study, we investigated the role of Ezh1 in regulating the innate immune response. We found that silencing of Ezh1 significa ...[more]

Project description:Dendritic cells (DC) play a crucial role in initiating, shaping and controlling the immune response. They are the most important antigen presenting cells in the immune system. DC can be divided in immature and mature DC. DCs reside in an immature state in most tissues or they circulate in the blood, where they recognize and phagocytose pathogens and other antigens. Direct contact with many pathogens leads to the maturation of DCs. The property to stimulate T cells is reserved for mature DC (O`Doherty, U. 1994). This functional maturation results in an up-regulation of the surface molecule MHC class II, adhesion molecules (CD54 and CD58) and co-stimulatory receptors (CD80 and CD86) as well as decreased antigen uptake capacity (CD206). (Banchereau, J. and Steinman, R.M. 1998). Immunosuppressive drugs have revolutionized organ transplantation and improved the therapeutic management of autoimmune diseases. These drugs interfere on lymphocytes but they also act at the earliest stage of immune response. They are targeting key functions of dendritic cells (Hackstein H. and Thomson A.W., 2004 review). Sanglifehrin A (SFA) is a new immunosuppressive drug. It is a representative of a class of macrolides produced by the actinomycetes strain Streptomyces A92-308110 that bind to cyclophilin A (CypA), the binding protein of cyclosporine A (CsA). Most studies about immunosuppressive effects of SFA took place on T and B lymphocytes. Unlike CsA, the cyclophilin-SFA-complex shows no effect on the calcium-dependent protein phosphatase calcineurin (Zenke, G. 2001). Unlike CsA and FK506, SFA shows no inhibition of IL-2 expression (Zenke, G. 2001; Zhang, L.H. 2001), nor does it suppress IL-2 receptor transcription (Zhang, L.H. 2001) in T lymphocytes. It could be shown that SFA reduces the Interleukin 12 production in dendritic cells (Steinschulte, C. 2003). IL-12p70 plays an important role in the pathogenesis of inflammation and autoimmune diseases. DCs generated in the presence of SFA show reduced macropinocytosis and lectin-mediated endocytosis. In contrast, CD89 und CD32 were increased by SFA. The effect of SFA on the expression of Ag uptake receptors and Ag capture by DCs makes SFA unique among other immunophilin-binding immunosuppressive drugs (Woltman, A. 2004). Our goal is to investigate the gene expression profile of SFA treated mature human monocyte-derived dendritic cells. Comparison of SFA-stimulated versus unstimulated cells. 7 biological replicates
