Chimeric yellow fever virus (YF) RNAs were constructed in which the YF structural genes were replaced by the hepatitis C virus (HCV) structural genes or fusions between the YF and HCV structural genes. Interestingly, RNA replication required nucleotide complementarity between the 3'-located conserved sequence 1 and an RNA sequence located in the 5' end of the YF capsid sequence. The (chimeric-)HCV structural proteins were efficiently expressed and processed, and the native E1/E2 heterodimer was formed. However, no indication for the production of HCV-like particles was obtained.
