Subsequently, the authors replicated these results by fusing the mutant Nef protein with other viral proteins, including hepatitis C virus (HCV)-NS3, Ebola virus (EboV)-VP24, EboV-VP40, and EboV-NP, West Nile virus (WNV)-NS3, influenza (Flu)-NP, and Crimean–Congo hemorrhagic fever (CCHFV)-NP [126]. The gene discussed is KRAS; the disease is hemorrhagic fever.
