Borna disease virus-specific antigens: two different proteins identified by monoclonal antibodies.
A variety of cells originating from different species, including man, can be infected with Borna disease (BD) virus. Two different virus infection-specific antigens with molecular weights of 24 kD and 35/38 kD (double band) could be demonstrated using antigen preparations from persistently infected cells and rat brains, and polyvalent antisera from naturally and experimentally infected animals. Three different monoclonal antibodies were selected. One was specific for the 24-kD protein and two others reacted with the 35/38-kD antigen. The 24- and 35/38-kD antigens could be monitored concomitantly with the appearance of newly synthesized infectious virus. Both antigens could be detected at the same time during the infection cycle, and showed identical distribution in the cell. Their relationship to one another and their possible function is discussed.
