微生物感染的成功清除取决于免疫系统先天和适应性两臂的协同作用。准确识别入侵病原体是引发有效抗菌防御机制的第一步也是最关键的一步。近年来,在了解先天免疫系统如何识别微生物特征(通常称为病原体相关分子模式(pathogen-associated molecular patterns, PAMPs))的分子细节方面取得了显著进展。对于病毒病原体,核酸——包括病毒基因组和病毒复制产物——代表了一类主要的PAMPs,它们通过激活种系编码的先天免疫受体来触发抗病毒宿主反应。本文综述了病毒RNA和DNA细胞内先天感知机制的最新研究进展。
Successful clearance of a microbial infection depends on the concerted action of both the innate and adaptive arms of the immune system. Accurate recognition of an invading pathogen is the first and most crucial step in eliciting effective antimicrobial defense mechanisms. In recent years, remarkable progress has been made towards understanding the molecular details of how the innate immune system recognizes microbial signatures, commonly called pathogen-associated molecular patterns (PAMPs). For viral pathogens, nucleic acids — both viral genomes and viral replication products — represent a major class of PAMPs that trigger antiviral host responses via activation of germline-encoded innate immune receptors. Here we summarize recent advances in intracellular innate sensing mechanisms of viral RNA and DNA.
