Appearance of immunoglobulin G Fc receptor in cultured human cells infected with varicella-zoster virus

Abstract

After infection with varicella-zoster virus, HeLa and human embryo lung cells developed a receptor for the Fc portion of human and rabbit immunoglobulin G. The receptor was detected by both hemadsorption and immunofluorescence, using antibody-coated erythrocytes and heat-aggregated immunoglobulin G. However, sheep erythrocytes sensitized with F(ab')2 of anti-sheep erythrocyte antibody did not adsorb to the receptor. When cell-free varicella-zoster virus was inoculated into the HeLa cell monolayer, the Fc receptor appeared at first 6 h after infection; varicella-zoster virus antigen in the cytoplasm and detectable cytopathic effects appeared later.
