Abstract excerpt
The nonstructural protein NS1 of influenza A virus counteracts the interferon (IFN) system and thereby promotes viral replication. NS1 has acquired different mechanisms to limit induction of IFN. It prevents double-stranded RNA (dsRNA) and RIG-I-mediated activation of interferon regulatory factor 3 (IRF3), and it blocks posttranscriptional processing of cellular mRNAs by binding to the cleavage and...
