Murine B cells can be activated via the surface receptors TLR4 and CD40. For a global assessment of differences in gene expression between these two different modes of B cell activation a genome wide transcriptome analysis was performed. In order to dissect different gene expression profiles of B cells, activation was induced by LPS or LPS + anti-CD40 for 24h and 72h. Both activation states were compared to each other but also to nave B cells.
IL-35-producing B cells are critical regulators of immunity during autoimmune and infectious diseases.

View SamplesInducible co-stimulator (ICOS) interaction with its ligand (ICOSL) is involved in several T cell effector functions. While blockade of ICOS:ICOSL interaction in chronic graft versus host disease (GVHD) seems benefi cial, results for acute GVHD remain controversial. To further elucidate its role in acute GVHD, C57BL / 6 mice were lethally irradiated and reconstituted with allogeneic spleen cells in the absence or presence of ICOSL-blocking mAb. Mice reconstituted with allogeneic spleen cells experienced severe GVHD and died untreated within 6 9 days after transplantation. Mice treated with an anti-ICOSL mAb starting from day 3 after transplantation gained weight again and survived for at least additional 12 days, although the treatment was already stopped at day 11 after transplantation. In contrast, the anti-ICOSL treatment starting from day 0 did not prevent GVHD. The diff erence between therapeutic (day 3) and prophylactic (day 0) anti-ICOSL treatment was independent of CD25 + CD4 + regulatory T cells since their depletion did not abrogate the therapeutic eff ect of ICOSL blockade. Microarray analysis revealed IFN- and chemokine up-regulation in spleen cells of prophylactically treated mice, emphasizing kinetic dependence of acute GVHD modulation via blockade of ICOS:ICOSL interaction.
Only therapeutic ICOS:ICOSL blockade alleviates acute graft versus host disease.

View SamplesWe performed RNA-sequencing in c-Kit+ cells that were infected with retroviruses expressing shRNAs for Renilla, Rad21, Smc1a, Smc3 or Stag2. These cells were grown in methylcellulose (M3434) for either one passage (P1) or replated for five passages (P5). Overall design: RNA-sequencing control (Ren) and cohesin (Rad21, Smc1a, Smc3 and Stag2) knockdown cells.
Cohesin loss alters adult hematopoietic stem cell homeostasis, leading to myeloproliferative neoplasms.

View SamplesTo identify soybean genes and QTLs associated with quantitative resistance to infection by the oomycete pathogen Phytophthora sojae, we conducted a very large-scale microarray experiment using 2522 Affymetrix GeneChips. The experiment involved assaying a total of 298 soybean recombinant inbred lines together with internal checks.
Infection and genotype remodel the entire soybean transcriptome.

View SamplesRat small intestine precision cut slices were exposed for 6 hours to in vitro digested yellow (YOd) and white onion extracts (WOd) that was followed by transcriptomics analysis. The digestion was performed to mimic the digestion that in vivo takes place in the stomach and small intestine. The transcriptomics response of the rat small intestine precision cut slices was compared to that of human Caco-2 cells and the pig in-situ small intestinal segment perfusion. The microarray data for the human Caco-2 cells (GSE83893) and the pig in-situ small intestinal segment perfusion (GSE83908) have been submitted separately from the current data on rat intestine. The goal was to obtain more insight into to which extent mode of actions depend on the experimental model. A main outcome was that each of the three models pointed to the same mode of action: induction of oxidative stress and particularly the Keap1-Nrf2 pathway.
