Evasion of the Innate Immune Type I Interferon System by Monkeypox Virus.

ABSTRACT:

Unlabelled

The vaccinia virus (VACV) E3 protein has been shown to be important for blocking activation of the cellular innate immune system and allowing viral replication to occur unhindered. Mutation or deletion of E3L severely affects viral host range and pathogenesis. While the monkeypox virus (MPXV) genome encodes a homologue of the VACV E3 protein, encoded by the F3L gene, the MPXV gene is predicted to encode a protein with a truncation of 37 N-terminal amino acids. VACV with a genome encoding a similarly truncated E3L protein (VACV-E3LΔ37N) has been shown to be attenuated in mouse models, and infection with VACV-E3LΔ37N has been shown to lead to activation of the host antiviral protein kinase R pathway. In this report, we present data demonstrating that, despite containing a
