Summary

Traduction automatique

Influenza A-virus (IAV) infektion aktiverer caspaserne, der spalter vært og virale proteiner, som igen har pro- og antivirale funktioner. Ved at anvende hæmmere, RNA-interferens, stedrettet mutagenese og western blotting og RT-qPCR-teknikker blev caspaser i inficerede pattedyrceller, der spalter værtscortactin og histondeacetylaser, identificeret.
