NCT00237432

Brief Summary

The purpose of this study is to investigate the mechanism of a successful immune response to hepatitis C virus (HCV) infection. Currently, it is believed that the immune system is involved in responding to HCV infection, but how it is involved is not known. It is estimated that 30% of individuals infected with HCV are able to clear the virus without treatment, while 70% progress to chronic infectious. By studying the immune responses in these two populations, we, the researchers at Rockefeller University, hope to gain insight into the mechanisms of the immune response and develop new strategies for HCV therapy.
