The guanosine analogue ribavirin was tested for antiviral activity
in two neural cell lines, human oligodendrocytes and rat glia, against
Borna disease virus (BDV) strains V and He/80. Ribavirin treatment
resulted in lower levels of virus and viral transcripts within 12 h. Addition of guanosine but not adenosine resulted in a profound
reduction of the ribavirin effect. Ribavirin appears to be an effective
antiviral agent for treatment of BDV infection in vitro. A likely
mechanism for its activity is reduction of the intracellular GTP pool,
resulting in inhibition of transcription and capping of BDV mRNAs.
