Abstract:
Viruses achieve their efficient reproduction by utilizing their limited components (nucleic acids, lipids, and proteins) and host cell machineries. A detailed understanding of virus-virus and virus-host interactions will lead to the elucidation of mechanisms underlying viral pathogenesis and the development of novel medical countermeasures. We elucidated the details of several such interactions and their roles in the multiplication of negative-strand RNA viruses, measles virus, and Lassa virus. These discoveries were harnessed to develop a novel genetic approach for the generation of live-attenuated vaccine candidates with a well-defined molecular mechanism of attenuation. This article describes our findings.
