Project description:The goal of this study was to study the gene expression changes that occurred in BL3 cells that were infected with type 2 bovine viral diarrhea virus (BVDV2). What happens within the cell and how the cell responds to the virus is completely unknown. Keywords: gene expression changes, BVDV2-infected cells, acute infection
Project description:Non-canonical microRNAs (miRNAs) are a class of short endogenous RNA molecules with the ability to control development, autophagy, apoptosis and the stress response in eukaryotes by pairing with partially complementary sites in the 3' untranslated regions (UTRs) of targeted genes. Recent studies have demonstrated that miRNAs serve as critical effectors in intricate networks of host-pathogen interactions. Thereforce, the differential expression of miRNAs were evaluated in Madin-Darby bovine kidney (MDBK) cells infected with bovine viral diarrhea virus (BVDV) NADL (100 TCID50/ 0.1 ml) for 6 h compared to normal MDBK cells using Solexa high-throughput sequencing technology (BGI, China).

What happens within the cell and how the cell responds to the virus is completely unknown. Keywords: gene expression changes, BVDV2-infected cells, acute infection This study compared the gene expression patterns in noninfected BL3 cells to that in cells that had been infected with BVDV2 for 18 hours. The 2 SAGE libraries were compared to each other to determine which transcripts were present at altered levels in the infected cells. This data will give clues to how the viral infection gives rise to the different pathologies observed in infected animals.

Project description:Vaccination with a new vaccine against bovine viral diarrhea (BVD) caused unwanted immune reactions through alloreactive antibody production in 5–10% of vaccinated cows. Transfer of these alloreactive antibodies via colostrum caused highly lethal (90%) bovine neonatal pancytopenia (BNP) in calves. Despite the assumption of an immune deviant lymphocyte (PBL) phenotype, the exact immunological mechanisms driving these unwanted immune reactions are not fully understood to date. To gain deeper insight into these mechanisms, we analyzed the PBL secretome from alloreactive antibody producers (BNP cows) and non-alloreactive responders (controls) after stimulation with pokeweed mitogen (PWM).

Transfer of these antibodies via colostrum caused bovine neonatal pancytopenia (BNP) in calves, with a lethality rate of 90%. The exact immunological mechanisms behind the onset of BNP are not fully understood to date, however, an immune deviant phenotype of immune cells is assumed. To gain deeper insight into disease onset and pathogenesis, we analyzed the lymphocyte (PBL) proteome from alloreactive antibody producers (BNP cows) and non-responders (controls) after stimulation with PWM.
