Questo video dimostra la generazione di particelle simili al virus dell'influenza (VLP) in un sistema di mammiferi. Dopo aver espresso tre vettori di espressione eucariotici, che codificano diverse proteine strutturali virali, in cellule ospiti di mammiferi idonee, le proteine virali espresse si autoassemblano in VLP sulla membrana plasmatica ospite e vengono rilasciate attraverso la gemmazione dalla superficie cellulare.
