TranscriptomicsTranscription profiling of spleens from dual specificity phosphatase-1 (DUSP1) deficient and wild type mice to demonstrate a specific regulatory role of DUSP1 on a subset of LPS-induced genes that control the outcome of endotoxin shock.
Activation of the Mitogen activated protein kinase (MAPK) cascade following Toll-like receptor (TLR) stimulation enables innate immune cells to rapidly activate cytokine gene expression. A balanced response to signals of infectious danger requires that cellular activation is transient. Here, we iden...

TranscriptomicsPRONOUNCED PHENOTYPE IN ACTIVATED TREG CELLS DURING A CHRONIC HELMINTH INFECTION
Although several markers have been associated with the characterization of regulatory T cells (Treg) and their function, no studies have investigated the dynamics of their phenotype during infection. Since the necessity of Treg to control immunopathology has been demonstrated, we used the chronic he...

TranscriptomicsTranscription profiling of human EBV infected EBNA-3 positive and negative human B lymphocytes
The genome of Epstein-Barr virus (EBV) encodes 86 proteins but only a limited set is expressed in EBV-growth transformed B cells, termed lymphoblastoid cell lines (LCLs). These cells proliferate via the concerted action of EBV nuclear antigens (EBNAs) and latent membrane proteins (LMPs), some of whi...

TranscriptomicsIKKα promotes intestinal tumorigenesis
Depending on the tumor type IκB kinase α (IKKα) can act as tumor promoter or tumor suppressor in various malignancies. Here we demonstrate a key function of IKKα in the suppression of a tumoricidal microenvironment during intestinal carcinogenesis. Mice deficient in IKKα kinase activity are largely ...

TranscriptomicsDusp9 expression and function in dendritic cells
Plasmacytoid dendritic cells (pDC) efficiently produce large amounts of type I interferon in response to TLR7 and TLR9 ligands, whereas conventional DCs (cDC) predominantly secrete high levels of the cytokines IL-10 and IL-12. The molecular basis underlying this distinct phenotype is not well unders...

TranscriptomicsComparison of gene expression profiles between human and mouse monocyte subsets [mouse data]
Human and mouse blood each contain two monocyte subsets. Here, we investigated the extent of their similarity using a microarray approach. Approximately 300 genes in human and 550 genes in mouse were differentially expressed between subsets. More than 130 of these gene expression differences were co...

TranscriptomicsAirborne particulate matter affects gene expression in BEAS-2B bronchial epithelial cells.
Background: In classrooms high concentrations of particulate matter PM10 were measured. It is unknown whether the hazard of indoor particles is similar to that of the better studied outdoor particles. This study therefore analyzed adverse biological effects of classroom in comparison to outdoor PM10...

TranscriptomicsCard9 dependent activation of macrophages by TDB
Bone marrow derived macrophages from wt and card9 KO mice were stimulated with CpG, Curdlan or TDB, an analogon to the mycobacterial cord factor TDM for 48h, respectively. Keywords: card9 knockout, macropphage, TDB wt or card9 KO macrophages stimulated for 48h

TranscriptomicsMicroarray analysis to evaluate the function of USP18 in the mouse CNS
Microglia are tissue macrophages of the central nervous system (CNS) that control tissue homeostasis, and as such they are crucially important for organ integrity. Microglia dysregulation is thought to be causal for a group of neuropsychiatric, neurodegenerative and neuroinflammatory diseases, calle...

TranscriptomicsNascent mRNA profiling of LPS-stimulated mouse macrophages
To identify transcriptionally regulated genes in primary mouse macrophages stimulated with LPS with high sensitivity, we isolated nascent RNA following metabolic labelling with 4-thiouridine during the last 35 min before cell harvest, as recently described (Dolken et al. 2008 RNA 14:1959-72). Microa...
