| Abstract: | Bovine respiratory syncytial virus (BRSV) is a major cause of respiratory disease in calves. BRSV infection is associated with epithelial cell death and inflammation. Over the past few years, a growing number of viruses have been found to induce apoptosis. In order to determine the ability of BRSV to induce apoptosis, we studied the effect of BRSV infection in cultured MDBK cells. We used ligation-mediated PCR assay to detect specific blunt-end cellular DNA fragments produced by cellular endonucleases cleaving the genomic DNA between the nucleosomes during apoptosis. We found that BRSV infection resulted in apoptosis in MDBK cells. This data demonstrates for the first time that BRSV can induce apoptosis. This data also may contribute to delineate the mechanisms that regulate tissue injury and potential lung repair following BRSV infection. |
