Fidelity of herpes simplex virus (HSV) DNA replication

We are investigating the mechanisms governing the fidelity of HSV DNA replication that plays the critical roles in the emergence of mutations leading to resistance to antiviral drugs. Current efforts are focusing on examining the effects of different mutations of the polymerase and the processivity factor, the UL42, on the fidelity of DNA replication. Also, by using a novel mutagenesis system, we are characterizing whether the DNA replication accuracy could be influenced by the position effect.

Drug resistance of human cytomegalovirus (CMV)

Drug resistance is the major problem of successful treatment of human cytomegalovirus. Our current researches include the development of a novel and rapid method for the detection of drug resistant strains, including both polymerase and UL97 mutants, from clinical samples. We are also investigating the natural substrate of UL97, the kinase responsible for phosphorylating the antiviral drug ganciclovir. The findings could be useful for the future development of new antiviral reagents. These researches will be beneficial to the clinical treatment of CMV infections, especially for immuno-suppressed individuals.
