Although most poxviruses are restricted to their hosts, some members can leap host species and cause zoonotic diseases and, therefore, are genuine threats to human and animal health. The recent global spread of monkeypox in humans suggests that zoonotic poxviruses can adapt to a new host, spread rapidly in the new host, and evolve to better evade host innate barriers. Unlike many other viruses, poxviruses express an extensive repertoire of self-defense proteins that play a vital role in the evasion of host innate and adaptive immune responses in their newest host species. The function of these viral immune modulators and host-specific cytokine responses can result in different host tropism and poxvirus disease progression. Here, we review the role of different cytokines that control poxvirus host tropism and adaptation.</p></div>","PeriodicalId":11082,"journal":{"name":"Current opinion in virology","volume":null,"pages":null},"PeriodicalIF":5.9,"publicationDate":"2022-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9704024/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"9754490","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To survive, viruses must adapt to evade or subvert these defenses while still capturing cellular resources to fuel their replication cycles. Large-scale studies of the antiviral activities of cellular proteins and processes have shown that different viruses are controlled by distinct subsets of antiviral genes. The remaining antiviral genes are either ineffective in controlling infection, or in some cases, actually promote infection. In these cases, classically defined antiviral factors are retasked by viruses to enhance viral replication. This creates a more nuanced picture revealing the contextual nature of antiviral activity. The same protein can exert different effects on replication, depending on multiple factors, including the host, the target cells, and the specific virus infecting it.
