Identification of genetic determinants of a tick-borne flavivirus associated with host-specific adaptation and pathogenicity.

abstract：:Adenoviruses with deletion of E1b have been used in clinical trials to treat cancers that are resistant to conventional therapies. The efficacy of viral replication within cancer cells determines the results of oncolytic therapy, which remains poorly understood and requires further improvement. In this report, we show...
