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

Abstract

Poxviruses have evolved to have many mechanisms to evade host antiviral innate immunity; these mechanisms may allow these viruses to cause disease. Within the family of poxviruses, variola virus (which causes smallpox) is the most pathogenic, while monkeypox virus is intermediate in pathogenicity between vaccinia virus and variola virus. Understanding the mechanisms of monkeypox virus innate immune evasion will help us to understand the evolution of poxvirus innate immune evasion capabilities, providing a better understanding of how poxviruses cause disease.
