Project description:In vivo microarray study of global gene expression changes in peripheral blood mononuclear cells (PBMCs) of German Landrace pigs during the innate immune response to porcine reproductive and respiratory syndrome virus vaccination.
Project description:Porcine alveolar macrophages were challenged in vitro with a low virulent strain of the Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) to identify and characterize the population of host genes subjected to miRNA post-transcriptional regulation durign early viral infection. We employed a high-throughput biochemical assay, i.e. the immunoprecipitation of RISCs followed by microarray analysis of the RISC-bound miRNA targets (RIP-Chip). qPCR analyses were carried out to validate the resolution of the microarray and to determine levels of expression of a panel of eight miRNAs (ssc-miR-142-3p, ssc-miR-142-5p, ssc-let-7f, miR-146a-5p, miR-155-5p, ssc-miR-181a, ssc-miR-21 and ssc-miR-335).
