Virus-Induced Specific Cell Surface Antigen(s) on Mouse Adenovirus-Infected Cells.
A virus-specific cell surface antigen(s) was detected on mouse adenovirus-infected cells by the immunofluorescent antibody technique. It was demonstrated in infected cells regardless of the mouse strain or animal species used. It became detectable on the cell surface about 6 h postinfection and was demonstrated in 90% of infected cells at 24 to 36 h postinfection. On the other hand, intracellular capsid antigens became detectable by the immunofluorescent antibody technique at about 24 h postinfection. Since it was also detected on virus-infected cells treated with 5'-fluorodeoxyuridine to block viral deoxyribonucleic acid synthesis, it was synthesized at the early stage of infection and may not be a virus structural component. The relationship between this serologically detectable cell surface antigen(s) and cell-mediated immune response to virus infections is discussed.
