Project description:MIcroRNA expression profiling of primary murine splenic dendritic cells (Flt3L expanded) comparing untreated cells to cells infected with Influenza A or stimulated with polyI:C in vitro. Three-condition experiment, Influenza A/PR/8/34 virus MOI=10 vs polyI:C 30 ug/mL vs. mock treated; RNA collected after 8 hours. 3 Independent biological replicates from cells prepared on different days. One replicate per array.

Project description:Primary murine bone marrow derived macrophages (BMDMs) of Setdb2GT/GT and WT mice were stimulated with polyI:C and harvested at 0, 2 and 8h. Everything with biological triplicates (=cells from 3 individual mice per condition)
Project description:CD8 positive dendritic cell line , stimulated with or without TLR3 ligand polyI:C We used microarray to obtain global gene expression data of TLR3 regulated genes
Project description:The project aim at studying transcriptional changes by BRB-seq of porcine alveolar epithelial cells line infected with wild type influenza virus compared to live attenuated influenza viruses. In addition, primary porcine nasal epithelial cells was also added to be able to compare how the alveolare epithelial cells line compare to primary cells. Finally, additional positive control including procine alveolar epithelial cells stimulated with Poly I:C or infected with IFN inducing Sendei virus was added.
Project description:Vaccine development involves time-consuming and expensive evaluation of candidate vaccines in animal models. As mediators of both innate and adaptive immune responses dendritic cells (DCs) are considered to be highly important for vaccine performance. Here we evaluated in how far the response of DCs to a vaccine in vitro is in line with the immune response the vaccine evokes in vivo. To this end, we investigated the response of murine bone marrow-derived DCs to whole inactivated virus (WIV) and subunit (SU) influenza vaccine preparations. These vaccine preparations were chosen because they differ in the immune response they evoke in mice with WIV being superior to SU vaccine through induction of higher virus-neutralizing antibody titers and a more favorable Th1-skewed response phenotype. To evaluate if in vivo immunogenicity is reflected by DC reactions in vitro we studied the gene expression signature of murine bone-marrow-derived conventional DCs (cDCs) upon stimulation with WIV or SU influenza vaccine or, for reasons of comparison, with live influenza virus. Dendritic cells stimulated with PBS served as a control. Gene expression analysis was performed on samples 4, 12 and 24 hours after the start of stimulation.
