The aim of this study was to investigate the humoral immune response to Borna disease (BD) virus in the brain of experimentally infected Lewis rats. Abundant IgG was detected in BD-rat brain with isotype variation throughout infection. IgG was locally produced as indicated by an intact blood-brain barrier, Ig kappa light chain mRNA-containing cells in brain and accumulation of virus-specific antibodies in cerebrospinal fluid. Treatment with BD-rat serum altered viral gene expression in persistently infected cultured rat glioblastoma cells. These data suggest that antibodies, produced in the brain, may influence viral gene expression.

It has previously been reported that de novo infection of primary rabbit brain cells with Borna disease virus (BDV) can be blocked with interferon-alpha/beta (IFN), whereas this cytokine has no inhibitory effect on BDV in persistently infected rat lung cells [v. Rheinbaben et al., J. Gen. Virol. (1985) 66: 2,777-2,780]. It remained unclear, however, whether these results indicated that IFN exclusively targets early steps of the BDV replication cycle or whether they simply reflected cell line differences. We now show that BDV replication was effectively inhibited by IFN in both acutely and persistently infected monkey Vero cells. By contrast, IFN had no clear protective effect on either de novo or persistent BDV infections of rat C6 glioblastoma cells. IFN protected C6 cells from the cytopathic effects of vesicular stomatitis virus, excluding the possibility that these cells are devoid of a functional IFN system. In primary rat fibroblasts and in a human oligodendroglial cell line, IFN induced an efficient antiviral state against BDV. These results indicate that BDV is highly susceptible to the antiviral effect of IFN in some cell lines, while others seem to lack undefined components of the IFN system which mediate protection against BDV.
