Human Cytomegalovirus (CMV) infection is common in the population; 90% of adults have antibodies to CMV. While in immunocompetent hosts CMV infection is usually asymptomatic, in immuno-compromised cohorts, including transplant recipients and HIV-infected individuals, CMV causes serious morbidity and mortality. Congenital CMV is the leading infectious cause of deafness and mental retardation in the United States. Approximately 40,000 new cases of congenital CMV infection are reported annually in the United States.
Research
Main Research Themes
CMV Inhibition by Artemisinin-derived Dimers
We have shown that artemisinin-derived dimers inhibit human CMV replication significantly more that artemisinin-derived monomers, a pattern that has been observed in inhibition of cancer cell lines. Current work focuses in identifying mechanisms of CMV inhibition by these compounds and their effects on cell-signaling pathways.
Models of Anti-viral Combination Therapy
We performed extensive analysis of CMV inhibition using combination of known CMV inhibitors. Using several models for analysis of drug combination we have shown that the slope parameter is an important factor in distinguishing between classes of CMV inhibitors and for analyzing the outcome of drug combination.
Role of WNT Pathway in CMV Replication
We have shown that in contrast to other herpesviruses (such as EBV and KSHV) CMV infection of human foreskin fibroblasts results in inhibition of the WNT pathway.
CMV Control by NOD1 and NOD2
We have shown that NOD1 and NOD2 recognize CMV and restrict virus replication. We are studying mechanisms of CMV control by NOD1 and NOD2, and the effects of their polymorphisms on virus replication.
Identify Novel CMV Inhibitors Using HTS
We recently completed a high-throughput screening of more than 400,000 compounds with NCATS and identified several scaffolds that inhibit CMV. Work in our lab is characterizing these new agents.
