Vaccine Technology III
For cell culture-based influenza vaccine production virus yield optimisation is of crucial importance. In particular, with the recent threat of the new H1N1 pandemic, not only seasonal vaccines but also pre-/pandemic vaccines have to be supplied in large quantities. In vivo influenza replication is limited by the immune system, but for production cell lines the impact of cellular defence mechanisms on virus yield is unknown. In influenza-infected adherent Madin-Darby canine kidney (MDCK) cells the interferon (IFN) response and subsequent induction of the antiviral state was monitored. Virus yield and host cell signalling intensity were strain-dependent. By over-expression of viral antagonists …
