Funded Activity Summary

Flaviviruses are the agents of many mosquito-transmitted infections such as encephalitis and dengue. Hepatitis C virus is a member of the same virus family. Using Australian flavivirus Kunjin as a model and advanced techniques in molecular biology, biochemistry and electron micriscopy, the research at SASVRC has established international leadership in the area of flavivirus RNA replication and ultrastructure of virus-infected cells. The objectives of this application are to advance further our understanding of how the flavivirus RNA replication complex synthesizes RNA and how this RNA is specifically packaged to produce infectious virus. To achieve these goals we will employ state-of-the-art molecular biology techniques based on manipulations with infectious complementary DNA copy of Kunjin virus RNA. The intimate understanding of these mechanisms in flavivirus replication should facilitate the design of efficient antiviral drugs by specifically targeting unique events in RNA replication and-or packaging. This may assist in the development of antiviral drugs for treatment of infections caused by other higly pathogenic flaviviruses in Australia, such as dengue, Japanese encephalitis and Murray Valley encephalitis, and in the rest of the wirld such as New York strain of West Nile virus as well as the related heptitis C virus. Understanding the mechanisms of Kunjin virus replication and assembly will also aid in the further development of this virus as a safe vaccine vector against other viruses, e.g. HIV, and diseases such as cancer.
