- Abstract: The initiation of cellular antiviral signaling depends on host pattern-recognition receptors (PRRs)-mediated recognition of viral nucleic acids that are known as classical pathogen-associated molecular patterns (PAMPs). PRRs recruit adaptor proteins and kinases to activate transcription factors and epigenetic modifiers to regulate transcription of hundreds of genes, the products of which collaborate to elicit antiviral responses. In addition, PRRs-triggered signaling induces activation of various inflammasomes which leads to the release of IL-1β and inflammation. Recent studies have demonstrated that PRRs-triggered signaling is critically regulated by ubiquitin and ubiquitin-like molecules. In this review, we first summarize an updated understanding of cellular antiviral signaling and virus-induced activation of inflammasome and then focus on the regulation of key components by ubiquitin and ubiquitin-like molecules.
