Abstract
Understanding the early events in viral biology holds the key to the development of potent preventives. In this study, fluorescent hepatitis C virus pseudoparticles (HCVpp) have been generated where the envelope glycoprotein of Hepatitis C virus (HCV) has an EGFP tag. Using these pseudoparticles, entry assays were conducted where their entry was tracked via confocal microscopy. Using this system, fusion of host and viral membranes is predicted to occur within 15 min of HCV entry. Using cells with a knockdown for Rab1a, HCV trafficking was observed to be altered, indicating a role of Rab1a in HCV trafficking. In conclusion, this study reports the generation and use of fluorescent HCVpp which may be used to understand the early events of viral entry. This system may be adapted for the study of other enveloped viruses as well.
