What is it about?
The influenza virus contains 8 genomic RNA segment. During segment replication errors occur that may results in the formation of segment containing deletions. Some of these segments can interfere with the replication of wt segments, and are termed defective interfering RNAs. If such RNAs are packaged into particles, the resulting defective interfering particles (DIPs) can inhibit spread of the wt virus. DIPs could serve as influenza therapeutics and vaccines. However, DIP production so far dependent on the use of infectious influenza virus, which is associated with safety concerns. The system reported here allows for DIP production in the absence of infectious virus.
Why is it important?
We report for the first time a cell based system that allows production of DIPs in the absence of infectious influenza virus. This system might aid approaches to develop DIPs for influenza therapy and prevention.
