Research Interests:

Lassa fever virus replication and host immune suppression

Lassa fever virus infection can lead to severe and sometime lethal hemorrhagic fever diseases in humans, for which there is no vaccine or effective drug. Studies of Lassa (LASV) and other pathogenic arenaviruses have been hindered by the strict requirement for BSL-4 containment to work with these select agents. We have recently developed an infectious molecular clone for a prototypic BSL2 arenavirus (i.e., Pichinde virus - PICV) as well as a safe and convenient mini-replicon system and a small animal model for LASV. These novel systems have afforded us with unique resources and unprecedented opportunities to investigate in details the processes of viral genome replication/transcription and virulence. We are also interested in characterizing a novel functional mechanism of the Lassa viral nucleoprotein in mediating host innate immune suppression (Qi, et al., 2010, Nature, 468: 779-783). These efforts may lead the development of effective therapeutics against this deadly viral pathogen.
