Kunjin virus replicon-based vaccine vectors: new developments and applications

Funded Activity Summary

The project is aimed towards further development of a unique gene expression and delivery system based on self-replicating RNA (replicon) of the nonvirulent Australian flavivirus Kunjin (KUN). A number of improvements in the design of KUN replicon vectors aimed to increase their efficiency and to optimize them for production of heterologous gene products with desired terminal sequences are proposed. Also proposed are improvements in the current KUN replicon packaging system and development of new packaging systems for production of large amounts of virus-like particles (VLPs) containing KUN replicon RNA enclosed in KUN coat proteins for use as potential vaccines. The vaccine potentials of the curent and newly developed KUN vectors and VLPs will be evaluated in mice using respiratory syncytial virus as a model. An entirely new direction proposed in this application is generation of chimeric fowlpox virus-KUN replicon vectors which will combine the advantages of both systems and may result in the generation of an ultimate vaccine vector.
