About this Research Topic
The innate immune system is crucial to defend against viruses or other pathogenic microbes in the early phases of infection. The response starts with detecting evolutionarily conserved structures, termed pathogen-associated molecular patterns (PAMPs), by a set of germline-encoded pattern-recognition receptors (PRRs). Following the detection of specific viral PAMPs, PRRs trigger the activation of intracellular signaling cascades, ultimately leading to the induction of type I interferons (IFNs), pro-inflammatory cytokines, and antiviral genes through the activation of interferon regulatory factor 3 (IRF3) and IRF7.
Antiviral pathways need to be tightly regulated to ensure successful antiviral defenses and avoid aberrant or dysregulation of host immune signaling. We believe that the Research Topic will give updated insights into the dynamic fields of PAMPs sensing in antiviral innate immunity and viral immune evasion. We hope it will serve the purpose of encouraging new research. This Research Topic will provide an overall picture of antiviral innate immune sensing signal pathways, regulation, and viral immune evasion. We welcome the submission of Original Research, Review, Mini-Review, Hypothesis and Theory, and Perspective articles that cover, but are not limited to, the following subtopics:
1. Mechanisms of different PRRs and their downstream key adaptors to trigger early antiviral innate immunity
2. Mechanisms used by host cells to positively or negatively regulate antiviral innate immune sensing signal pathway
3. Viral immune evasion mechanisms by targeting immune sensors, adaptor molecules, intracellular kinases, and transcription factors
