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

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.

Effect of MHC II expression in pro-B cells: Pre-B cells and follicular B cells from wild-type and MHC II conditional mice

Project description:Hardy’s Fraction D bone marrow pre-B cells and splenic follicular B cells were purified by flow cytometry according to MHC II expression from wild-type and ItgaxcreH2-Ab1c MHC II conditional mice and transcriptionally profiled by RNA-seq. Duplicate or triplicate samples for each genotype and level of MHC II expression were sequenced. This is part of ongoing investigation of a possible cell-intrinsic role of MHC II B cells.

The regulatory roles of Ezh2 in response to lipopolysaccharide (LPS) in macrophages and mice with conditional Ezh2 deletion with LysM-Cre system

Project description:The responses of macrophages to lipopolysaccharide (LPS) might determine the direction of clinical manifestations of sepsis, which is the immune response against severe infection. Meanwhile, the enhancer of zeste homologue 2 (Ezh2), a histone lysine methyltransferase of epigenetic regulation, might interfere with LPS response. With a single LPS stimulation, Ezh2 null(Ezh2flox/flox; LysM-Crecre/−) macrophages demonstrated lower supernatant TNF-α than Ezh2 control (Ezh2fl/fl; LysM-Cre−/−), perhaps due to an upregulation of Socs3, which is a suppressor of cytokine signaling 3, due to the loss of the Ezh2 gene. In LPS tolerance, Ezh2 null macrophages indicated higher supernatant TNF-α and IL-6 than the control, supporting an impact of the loss of the Ezh2 inhibitory gene. In parallel, Ezh2 null mice demonstrated lower serum TNF-α and IL-6 than the control mice after an LPS injection, indicating a less severe LPS-induced hyper-inflammation in Ezh2 null mice. In conclusion, an absence of Ezh2 in macrophages resulted in less severe LPS-induced inflammation, as indicated by low serum cytokines, with less severe LPS tolerance, as demonstrated by higher cytokine production, partly through the upregulated Socs3.

LPS-stimulated wildtype and miR-146a KO murine C57BL/6 Bone Marrow-derived Dendritic Cells

Project description:Dendritic cells isolated from murine bone marrow were cultured for 7 days and then stimulated with 100 ng/mL LPS for 24h. Cells were derived from either wildtype or microRNA-146a knock-out mice. Total RNA was isolated from the cells following stimulation.

Transcription profiling of mouse bone marrow-derived dendritic cells stimilated with LPS in the presence or absence of cAMP

Project description:genes regualted by LPS or LPS+cAMP stimulation in BMDCs; We used microarrays to identify genes that up-regulated by LPS+cAMP compared with just LPS. Experiment Overall Design: BMDCs were stimilated with LPS (10 ng/ml) in the presence or absence of cAMP (100 microM) for 3h. Specifically up-regualted gene by cMP was identified.

Gene expression by cyotosolic DNA stimulation

Project description:STING molecule has been reported to be important adaptor molecule for cytosolic DNA sensing. We investigated gene expression by cytosolic DNA stimulation using bone marrow derived dendritic cells. We comparared gene expression profile between WT and STING knock out BMDCs after cytosolic DNA stimulation. We generated BMDCs by culturing in the presence of GM-CSF. BMDCs were stimulated by purified tumor-cell derived DNA using lipofectamine. After 7 hrs incubation, total RNA was isolated using Rneasy kit (Qiagen) and microarray was performed at genomic core facility in university of Chicago

Gene expression in dendritic cells stimulated with LPS in conditions allowing or inhibiting NFAT activation

Project description:Interleukin-2 (IL-2) is one of the molecules produced by mouse dendritic cells (DCs) after stimulation by Toll like receptor (TLR) agonists. By analogy with the events following T-cell receptor (TCR) engagement leading to IL-2 production we have observed that DC stimulation with lipopolysaccharide (LPS) induces Src-family kinase and phospholipase C (PLC)Î³2 activation, influx of extracellular Ca2+ and calcineurin-dependent nuclear NFAT translocation. We have also observed that the initiation of this pathway is independent of TLR4 engagement, and dependent exclusively on CD14. To determine the role of NFAT in LPS activated dendritic cells we have performed microarray analysis in conditions allowing or inhibiting NFAT activation. We show here that LPS-induced NFAT activation via CD14 is necessary to cause death of terminally differentiated DCs, an event that is essential for maintaining self-tolerance and preventing autoimmunity. Consequently, blocking this pathway in vivo causes prolonged DC survival and an increase in T cell priming capability. Gene expression analyses were performed using Affymetrix GeneChips in the following groups of murine bone marrow-derived dendritic cells: 1) CD14-deficient BMDCs stimulated with LPS; 2) wtBMDCs stimulated with LPS in presence of EGTA; 3) wtBMDCs stimulated with LPS. This experimental setting allowed us to select for effects due to Ca2+ fluxes and exclude the effects due to other causes, particularly the block of TRIF recruitment in CD14-deficient cells and the EGTA effects unrelated to Ca2+ chelation.

Gene expression profiling in wild-type, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO BMDCs unstimulated or stimulated with CpG-B ODN

Project description:To characterize the relationship between IRF5 and Lyn in innate immune responses at a genome-wide scale, we performed gene expression microarray analysis for wild-type (WT), Irf5-KO, Lyn-KO and Lyn/Irf5-DKO bone marrow-derived dendritic cells (BMDCs) with or without 6 h-stimulation with 150 nM CpG-B ODN. We extracted the transcripts that were upregulated by CpG-B ODN in WT BMDCs, further upregulated in Lyn-KO BMDCs and then downregulated in Lyn/Irf5-DKO BMDCs (fold change â?¥ 2, false discovery rate < 0.05). When these 79 transcripts were sorted by their expression levels in Lyn-KO BMDCs, most of the top 20 genes (13 out of 20) were those encoding type I interferons (IFNs), indicating that Lyn particularly suppresses IRF5 induction of type I IFNs. BMDCs from WT, Irf5-KO, Lyn-KO and Lyn/Irf5-DKO mice in a C57BL/6 background were unstimulated or stimulated with CpG-B ODN. Biological triplicate for each genotype were analyzed (24 samples in total).
