| Summary: | ABSTRACT Poxviruses comprise pathogens that are highly pathogenic to humans and animals, causing diseases such as smallpox and mpox (formerly monkeypox). The family also contains members developed as vaccine vectors and oncolytic agents to fight other diseases. Vaccinia virus is the prototype poxvirus and the vaccine used to eradicate smallpox. Poxvirus genes follow a cascade temporal expression pattern, categorized into early, intermediate, and late stages using distinct transcription factors. This review comprehensively summarized the temporal expression classification of over 200 vaccinia virus genes. The relationships between expression classes and functions, as well as different branches of immune responses, were discussed. Based on the vaccinia virus orthologs, we classified the temporal expression classes of all the mpox virus genes, including a few that were not previously annotated with orthologs in vaccinia viruses. Additionally, we reviewed the functions of all vaccinia virus genes based on the up-to-date published papers. This review provides a readily usable resource for researchers working on poxvirus biology, medical countermeasures, and poxvirus utility development. |
