- Effect of hepatitis C Virus (HCV) on dendritic cell immunobiology
- The study tested the hypothesis that HCV-derived proteins may interfere with antigen presentation. Specifically, 1) how is gene expression within the dendritic cell affected by the presence of virally derived HCV proteins? And 2) how is the antigen presentation function of dendritic cells affected by the presence of HCV proteins?

- Pilot: ” Interference with T cell recognition by HCV-derived proteins”
- Specific Aims: 1)Determine if expression of HCV genes (using recombinant vaccinia virus vectors) leads to diminished cell surface expression of molecules required for recognition by CD4+ and CD8+ T lymphocytes; 2) Determine if expression of HCV genes (using recombinant vaccinia vectors) interferes with the antigen-specific recognition by CD4+ and CD8+ T cell clones.

- Cellular Immune Mechanisms of Resistance to HCV Therapy
- The major goals were to investigate the Th1/Th2 paradigm in chronically infected HCV-positive patients undergoing antiviral therapy, how functional T lymphocyte responses are modified by therapy (change in magnitude and specificity), and to address the underlying immune mechanisms of impaired responsiveness to antiviral therapy in HCV-infected African-Americans.
- Role: Co-investigator

- Immune Responses in Acute Hepatitis C Infection
- The major goals were to investigate the CD4+ and CD8+ T cell response to HCV early after infection, to map T cell determinants, and define the role of CTL mutational escape as a mechanism of viral persistence.
