Infiltrating monocyte derived macrophages (MDMs) and resident microglia dominate CNS injury sites. We show that MDMs and microglia can directly communicate to modulate each others function. Also, the presence of MDMs in CNS injury suppresses microglia-mediated phagocytosis and inflammation. We suggest that macrophages infiltrating the injured CNS provide a mechanism to control acute and chronic microglia-mediated inflammation, which could otherwise drive damage in a variety of CNS conditions.
Peripherally derived macrophages modulate microglial function to reduce inflammation after CNS injury.

View SamplesAutoimmune pancreatitis (AIP) is a recently identified disease of the pancreas with unknown etiology and antigens. The aim of this study was to determine new target antigens and differentially regulated genes and proteins by means of transcriptomics and proteomics and to validate them in patients with autoimmune pancreatitis. Here we report a distinct downregulation at the RNA and protein level of pancreatic proteases (anionic trypsinogen, cationic trypsinogen, mesotrypsinogen, elastase IIIB) and pancreatic stone protein in autoimmune pancreatitis in comparison to alcohol-induced chronic pancreatitis.

View SamplesThe RNA-binding protein FUS is implicated in transcription, alternative splicing of neuronal genes and DNA repair. Mutations in FUS have been linked to human neurodegenerative diseases such as ALS (amyotrophic lateral sclerosis). We genetically disrupted fus in zebrafish (Danio rerio) using the CRISPR-Cas9 system. The fus knockout animals are fertile and did not show any distinctive phenotype. Mutation of fus induces mild changes in gene expression on the transcriptome and proteome level in the adult brain. We observed a significant influence of genetic background on gene expression and 3’UTR usage, which could mask the effects of loss of Fus. Unlike published fus morphants, maternal zygotic fus mutants do not show motoneuronal degeneration and exhibit normal locomotor activity. Overall design: We performed paired-end sequencing (100bp reads) of the polyA+ transcriptome from brains of five individuals with Fus-/- genotype and four with Fus wild type genotype. Note on RNA-Seq replicates: after performing first RNA sequencing on four replicates of Fus-/- and WT (labeled with the prefix "Sample_imb_ketting_2014_13_") we received a notice from Illumina stating a problem with the library preparation kit lot that was used to prepare the libraries. Due to that, we performed RNA sequencing a second time, using the same input RNA, except for the Fus knockout replicate #3, because there was not enough input RNA left. Instead, a different Fus knockout replicate (#1) was sequenced. However, we compared the mapped reads from sequencing run 1 and sequencing run 2 using plotCorrelaction from DeepTools, and the samples are highly correlated (at least 0.97 and 0.95, Spearman and Pearson correlation respectively). Therefore, we considered first ("Sample_imb_ketting_2014_13_") and second sequencing runs as technical replicates.

In human ECs, PPAR?-deficiency was studied using siRNA strategy and RNA sequencing was utilized to reveal angiogenesis-associated targets for PPARg. Overall design: Our aim is to reveal the possible role of PPARy in angiogenesis.

View SamplesPancreatic Ductal Adenocarcinoma (PDAC) is one of the most aggressive human malignancies. In our studies, we find that the Gli transcription factors are required for Kras initiation of pancreatic tumorigenesis. In order to identify the downstream transcriptional targets of Gli in PDAC, we conducted gene expression analysis using Gli3T, a transcriptional repressor of Gli.
The activity of Gli transcription factors is essential for Kras-induced pancreatic tumorigenesis.

Changes in intestinal immune activity have been documented to occur prior to the development of fulminate polyposis. Such changes are thought to contribute to disease development.
