Destruction of L Cells by Mengo Virus: Use of Interferon to Study the Mechanism

PMCID: PMC375650  PMID: 4301505

Abstract

Interferon, when added to L cells, inhibited the synthesis of infectious Mengo viral ribonucleic acid, hemagglutinins, and infectious virus by 85 to 95%. Serum-blocking antigens were also reduced by the action of interferon, but threefold excess amounts of these antigens accumulated in interferon-treated cultures above the amounts expected for the quantity of infectious virus that was produced in these cultures. Radioautographic analysis showed that 28 to 36% of the cells of an interferon-treated population synthesized viral ribonucleic acid and 36 to 47% produced viral antigens as determined by an immunofluorescence technique. Despite the reductions in synthesis of viral components, all cells in an interferon-treated culture underwent cytopathic effects at the same time as cells in infected cultures which had not been treated with interferon. The results are compatible with the hypothesis that the cell destruction which results from the infection of L cells with Mengo virus is due to a protein which is coded for by the virus but is not a component of the mature virion.
