Interferon treatment inhibits glycosylation of a viral protein

Abstract
The effects of tunicamycin (TM) and IFN [interferon] in [mouse fibroblast] L cells are compared. Treatment with TM or IFN reduced the production of infectious VSV [vesicular stomatitis virus] particles, decreased the amount of G and M proteins in VSV released from treated cells, and inhibited an early step in the formation of asparagine-linked oligosaccharide chains, the incorporation by membrane preparations from treated cells of N-acetylglucosamine into glycolipids with the properties of dilichol derivatives.
