Claims (9)

1. Fremgangsmåde til fremstillingen af et biofarmaceutisk produkt, omfattende: (a) inficere en biofarmaceutisk-producerende insektcelle med mindst ét baculovirus, idet det mindst ene baculovirus omfattende et genom der koder for det biofarmaceutiske produkt, og (b) opretholde den biofarmaceutisk-producerende insektcelle under betingelser så at det biofarmaceutiske produkt fremstilles, hvor genomet af det mindst ene baculovirus er mangelfuldt for vp80 eller hvor den biofarmaceutisk-producerende insektcelle omfatter et ekspressionskontrolsystem der tillader aktiveringen af vp80.
2. Fremgangsmåden ifølge krav 1, hvor - vp80 er gjort mangelfuldt i genomet ved hjælp af nukleotidsubstitution, insertion eller deletion; eller - hvor den biofarmaceutisk-producerende insektcelle er en rekombinant insektcelle omfattende et konstrukt der udtrykker dsRNA der er specifik for vp80, dsRNA'et udtrykkes eventuelt under en inducerbar promotor.
3. Fremgangsmåden ifølge krav 1 eller 2, hvor det mindst ene baculovirus fremstilles før trin (a) i en baculovirus-producerende celle der udtrykker en komplementerende kopi af vp80.
4. Fremgangsmåden ifølge et hvilket som helst af kravene 1 til 3, hvor mangelfuldheden eller inaktivering af vp80 ikke påvirker meget sen ekspression fra baculovirus i sammenligning med meget sen ekspression fra vild-type baculovirus.
5. Fremgangsmåden ifølge et hvilket som helst af kravene 1 til 4, hvor det biofarmaceutiske produkt er et rekombinant protein, et rekombinant virus eller en virus-lignende partikel.
6. Fremgangsmåden ifølge krav 5, hvor the biofarmaceutisk produkt er et rekombinant AAV.
7. Fremgangsmåden ifølge et hvilket som helst af kravene 1 til 6, hvor det biofarmaceutiske produkt kodes af mindst ét gen indført i det rekombinante baculovirusgenom under kontrollen af polyhedrin eller plO promotor.
8. Fremgangsmåden ifølge et hvilket som helst af kravene 1 til 7, hvor det mindst ene baculovirus er afledt fra AcMNPV eller BmNPV.
9. Anvendelse af et baculovirus-insektcellesystem til fremstillingen af et biofarmaceutisk produkt hvor baculovirus-insektcellesystemet omfatter en baculovirus-producerende insektcelle inficeret med mindst ét rekombinant baculovirus, hvor: - den, eller hvert, rekombinante baculovirus omfatter et baculovirusgenom der koder for det biofarmaceutiske produkt, eller mindst én komponent af det biofarmaceutiske produkt, og - den, eller de, rekombinante baculovirale genom er mangelfuldt for vp80, eller den baculovirus-producerende insektcelle omfatter et ekspressionskontrolsystem der tillader aktiveringen af vp80.
