The long-term goal of this program is the development of vaccines to prevent infections and immunotherapies to modulate the progression of chronic liver disease.
My research interests include the study of innate and adaptive immune responses to viral infections, in particular infections of the liver. Much of my work has focused on hepatitis B (HBV) and hepatitis C (HCV) infections, which affect about 500 million people worldwide. The spectrum of disease ranges from acute to chronic hepatitis, liver cirrhosis, and hepatocellular carcinoma. Although HBV infection can be prevented by a vaccine, there is still no curative treatment for most who are already chronically infected because antiviral agents do not eliminate the transcriptional template of HBV, the covalently closed circular DNA. For HCV, a vaccine has not yet been developed.
Applying our Research
This research will help decrease the burden of liver disease—in particular, chronic viral hepatitis—and the long-term consequences of chronic inflammation of the liver such as cancer. In addition, the basic immunological mechanisms that are being studied may be relevant to other diseases; for example, what we learn from the immune responses against hepatitis viruses can inform research on other pathogens and tumors that are also targeted by the immune system.
Need for Further Study
In both HBV and HCV infections, chronic liver disease is thought to be immune-mediated. The rate of liver disease progression to liver cirrhosis varies greatly among infected individuals, and the factors that regulate inflammation and disease progression are largely unknown. In particular, my laboratory is interested in analyzing the role of innate immune responses—in particular those mediated by innate cytokines and natural killer cells—in chronic liver inflammation.
