Abstract: The present inventors developed hepatitis C reporter viruses containing Core through NS2 of prototype isolates of all major HCV genotypes and the remaining genes of isolate JFH1, by insertion of reporter genes in domain III of HCV NS5A. The inventors have identified a deletion upstream of the inserted reporter gene sequence, which conferred favourable growth kinetics in Huh7.5 cells to these viruses. These reporter viruses can be used for high throughput analysis of drug and vaccine candidates as well as patient samples. Drugs could be evaluated for their potential to prevent infection or cure infected cells. The neutralizing capacity of antibodies induced by vaccine candidates could be evaluated in order to define successful vaccination strategies. Broadly neutralizing antibodies could be identified testing engineered antibodies and antibodies derived from serum of HCV infected individuals; thus this technique could contribute to the development of immunotherapy.
