Abstract
The role of RNA interference (RNAi) in mammalian antiviral immunity remains debated, partly due to variations in experimental models. Here, we critically examine key factors influencing the detection and interpretation of antiviral RNAi, including virus selection, infection efficiency, and small RNA profiling. We highlight the limitations of certain viral models and the need for rigorous methodologies to distinguish canonical virus-derived small interfering RNAs from degradation products. Additionally, we discuss the challenges of using transgenic mouse models to study Dicer-mediated antiviral responses. Standardizing experimental approaches will be essential for clarifying the role of RNAi in mammalian antiviral defense.
期刊介绍:
Nucleic Acids Research (NAR) is a scientific journal that publishes research on various aspects of nucleic acids and proteins involved in nucleic acid metabolism and interactions. It covers areas such as chemistry and synthetic biology, computational biology, gene regulation, chromatin and epigenetics, genome integrity, repair and replication, genomics, molecular biology, nucleic acid enzymes, RNA, and structural biology. The journal also includes a Survey and Summary section for brief reviews. Additionally, each year, the first issue is dedicated to biological databases, and an issue in July focuses on web-based software resources for the biological community. Nucleic Acids Research is indexed by several services including Abstracts on Hygiene and Communicable Diseases, Animal Breeding Abstracts, Agricultural Engineering Abstracts, Agbiotech News and Information, BIOSIS Previews, CAB Abstracts, and EMBASE.
