Project description:This dataset is composed of the unique patients (276; at the Day 1 timepoint) that are present in the six other GEO datasets published by Hector Wong and the Genomics of Pediatric SIRS and Septic Shock Investigators. This dataset thus includes all unique patients from GSE4607, GSE8121, GSE9692, GSE13904, GSE26378, and GSE26440. These are only from the Day 1 timepoint.

Project description:In the context of studying visceral leishmaniasis, neutrophils infected with Leishmania donovani have been compared to uninfected neutrophils. Compared time points are 0, 6 and 24 hours post infection. Neutrophils of three human donors have been used. Overall 6 samples for infected neutrophils at time point 6 hours and 6 samples for infected neutrophils at time point 24 hours exist, including three biological samples and two technical samples. Uninfected neutrophils represent 3 samples at time point 0 hours, 3 samples at time point 6 hours and 3 samples at time point 24 hours. Transcriptome of Leishmania donovani culture has been assessed in two replicates.

Project description:The project examines the mechanisms of neutrophil dysfunction during sepsis. Our work uncovered the central role of cell free circulating histones in eliminating mature neutrophil in favour of immature cells and characterized the mechanisms that regulate their release following systemic infection. Mature and immature neutrophil Ly6Ghigh and Ly6Glow populations isolated from the spleens of WT and TCRα-deficient mice either naïve or infected with C. albicans were characterized. In addition, these populations were compared to neutrophils isolated from WT mice receiving Clodronate-liposomes and recombinant G-CSF. These studies demonstrated that T-cell derived histones drive the release of G-CSF in the spleen and progressively eliminate mature neutrophils by shortening their lifespan. Finally, we conducted proteomic analysis of plasmas isolated from patients with microbial sepsis to correlate markers of neutrophil death to plasma cytokine and histone levels, confirming the pathogenic role these molecules play during sepsis in humans.

Project description:Neutrophils provide immune protection against pathogens but also may promote tissue injury in inflammatory diseases. Although neutrophils are generally considered as a relatively homogeneous population, evidence for heterogeneity is emerging. Under steady-state conditions, neutrophil heterogeneity may arise from ageing and the replenishment by newly released neutrophils from the bone marrow. We used microarray to globally analyze gene expression in aged neutrophils and characterize the inflammatory programs that are activated during the aging process in the circulation. Control, aged and activated neutrophils were sorted directly from mouse blood for RNA extraction and hybridization on Affymetrix microarrays. We transfused whole blood and harvested donor neutrophils marked by the CD45.1 allele 6h later to derive neutrophils that had truly aged in vivo. Sorted neutrophils were compared to control donor neutrophils that had been transferred for only 10 min. Additionally, we harvested circulating neutrophils from TNF-? treated mice for comparison with neutrophils activated by systemic inflammation.

Project description:Mice were infected with Helicobacter pylori strain SS1 for 2, 7, 14 or 28 days or left uninfected. They were sacrificed at the appropriate times, the stomachs were removed and one half was plated for colony counts. The other half was embedded in OCT and cryosections were produced for 6-7 animals per timepoint. The sections were stained using the Histogene dye and roughly 500-1000 cells per gastric epithelial cell type were harvested by laser microdissection. RNA was prepared from these samples, subjected to two rounds of amplification, labelled and hybridized to 40.000 element murine cDNA arrays. The array names are composed as follows: "LCM" stands for laser capture microdissection; "mock" or "SS" stands for mock-infected or SS1-infected, respectively; "2,7,14 and 28" refers to the length of infection; "1-4" corresponds to the numbers given to every animal.The cellular origin of the RNA is represented by "mucus producing" or pit cell, "parietal" or acid-producing cell and "chief" or zymogenic cell. Between 5 and 7 samples were harvested per timepoint and cell type. Where the first labelling reaction and hybridization did not produce sufficiently good data (less than half of all spots made a regression correlation cutoff of >0.6), both were repeated (indicated by the addition of "relabeled" to the array name). The differential regulation of genes can be analyzed in both a time and cell type specific manner using publicly available software. Cell Type: "mucus producing" or pit cell (pit), acid-producing cell (parietal) and zymogenic cell (chief)
