Research interests:

Molecular analysis of enterovirus 71-host interaction: Enterovirus 71 (EV71) is an enterovirus of the family Picornaviridae that possesses a positive-stranded RNA genome. Positive-stranded RNA virus infection induces the rearrangement of intracellular membranes into characteristic vesicles which assemble into an RNA replication complex where the viral RNA replication takes place. We have been keen in the understanding the EV71 replication process, in which we have identified host proteins, miRNA, and ER stress signaling pathways required for replication complex-associated membrane formation.

Drug discovery against EV71 and influenza viruses: Recurring of enterovirus 71 and influenza virus imposes substantial financial and social burdens each year worldwide. The current lack of approved therapeutic agents for EV71 and emerging drug-resistant influenza viruses motivate us to develop new antiviral compounds. We aim to identify and study the antiviral mechanisms of the small synthetic compound and natural products, and to test their in vivo activities in animal models.
