Research ArticleOpen accessEvery word in the titleInteraction of a C-terminal Truncated Hepatitis C Virus Core Protein with Plasmid DNA Vaccine Leads to in vitro Assembly of Heterogeneous Virus-like ParticlesNelson Acosta-Rivero, Joanna Poutou, Alexis Mussachio et al.Recently, it has been shown that HCV core proteins (HCcAg) with C-terminal deletions assemble in vitro into virus-like particles (VLPs) in the presence of structured RNA molecules. Results presented in this work showed that a truncated HCcAg variant covering the first 120 aa (HCcAg.120) with a 32 aa N-terminal fusion peptide (6xHistag-XpressTMepitope) interacts with plasmid DNA vaccine. Interestingly, the buoyant … …American Journal of Infectious Diseases, Vol. 1, Issue 1 · 31 Mar 2005 · 6,754 accessesView PDFCite
