    Abstract:
    Subacute sclerosing panencephalitis (SSPE) is a fatal neurodegenerative disease caused by prolonged persistent infection of the central nervous system with a measles virus (MV) mutant called SSPE virus. At present, there is no effective treatment to completely cure SSPE and development of a new therapeutic measure(s) against this fatal slow virus infection is needed. We previously reported that replication of MV and SSPE virus was effectively inhibited by small interfering RNA (siRNA), either chemically synthetic or plasmid-driven ones, that were targeted against different sequences of the mRNA for the L protein of MV. In this study, we have generated recombinant adenovirus expressing the siRNAs (rAd-siRNA-MV-L2, -L4 and -L5) and demonstrated that these rAd-siRNAs efficiently inhibited replication of MV and SSPE virus in a dose-dependent manner. Due to their high capacity for gene delivery to nerve cells and the potential to inhibit SSPE virus replication, the rAd-siRNAs could be a good candidate for a novel therapeutic measure against SSPE.
