Hemagglutinin stability and its impact on influenza A virus infectivity, pathogenicity, and transmissibility in avians, mice, swine, seals, ferrets, and humans

CJ Russell - Viruses, 2021 - mdpi.com
Genetically diverse influenza A viruses (IAVs) circulate in wild aquatic birds. From this
reservoir, IAVs sporadically cause outbreaks, epidemics, and pandemics in wild and …

The host RNA polymerase II C-terminal domain is the anchor for replication of the influenza virus genome

T Krischuns, B Arragain, C Isel, S Paisant… - Nature …, 2024 - nature.com
The current model is that the influenza virus polymerase (FluPol) binds either to host RNA
polymerase II (RNAP II) or to the acidic nuclear phosphoprotein 32 (ANP32), which drives its …

Structures of influenza A and B replication complexes give insight into avian to human host adaptation and reveal a role of ANP32 as an electrostatic chaperone for …

B Arragain, T Krischuns, M Pelosse, P Drncova… - Nature …, 2024 - nature.com
Replication of influenza viral RNA depends on at least two viral polymerases, a parental
