Title Restricted viral cDNA synthesis in cell lines that fail to support productive infection by bovine leukemia virus.
Journal Arch. Virol.
Abstract Bovine leukemia virus (BLV) is the causative agent of enzootic bovine leucosis, which results in significant economic losses on many affected farms. BLV infects a wide range of animals as well as cell lines derived from various mammalian species and organs; however, studies show that only some cell lines support sustained production of viral progeny. The differences between cells that produce viral progeny and those that do not are unclear. The aim of this study was to identify the steps of BLV replication that are associated with the capacity of a cell to support a productive infection. Eleven cell lines derived from various species were categorized into two groups, those that produce BLV progeny and those that do not, and the efficiency of viral attachment was compared. In addition, viral entry and reverse transcription were compared for two BLV-producing cell lines and three non-producing cell lines. BLV attached to and entered all of the tested cells. However, synthesis of viral DNA was inhibited in all three non-virus-producing cell lines, suggesting that BLV production was blocked either prior to or at the stage of reverse transcription. These results increase our understanding of the BLV life cycle and should enable better control over the spread of BLV.
