Multiple anti-interferon actions of the influenza A virus NS1 protein

G Kochs, A García-Sastre… - Journal of virology, 2007 - Am Soc Microbiol
The replication and pathogenicity of influenza A virus (FLUAV) are controlled in part by the
alpha/beta interferon (IFN-α/β) system. This virus-host interplay is dependent on the …

[HTML][HTML] A site on the influenza A virus NS1 protein mediates both inhibition of PKR activation and temporal regulation of viral RNA synthesis

Influenza virus non-structural protein NS1: interferon antagonism and beyond

D Marc - Journal of General Virology, 2014 - microbiologyresearch.org
Most viruses express one or several proteins that counter the antiviral defences of the host
cell. This is the task of non-structural protein NS1 in influenza viruses. Absent in the viral …
