Postattachment events associated with viral entry are necessary for induction of interferon-stimulated genes by human cytomegalovirus

J Virol. 2004 Jun;78(12):6688-91. doi: 10.1128/JVI.78.12.6688-6691.2004.

Abstract

Utilizing a human cytomegalovirus-specific fusion inhibitor and an antiglycoprotein H antibody, we studied the role of virion fusion in interferon-stimulated gene (ISG) induction. Our results indicate that ISG induction does not occur when virion-mediated, post-high-affinity attachment events are inhibited by either reagent. Thus, virion-mediated postattachment events, such as fusion, are required for ISG induction.
