Our lab investigates the host genetics and host response to chronic viral hepatitis infections including hepatitis B virus (HBV) and hepatitis C virus (HCV) in people with and without co-infection with HIV. For both of these viruses, some individuals can recover from the infection (with HCV they clear it but with HBV they suppress replication without medications) and some individuals have a chronic infection. Our overall goal for the HBV studies is to understand the immune response to HBV to aid in the development of a cure. Current studies include: 1) HBV virology in single hepatocytes from liver tissue obtained through laser capture microscopy, 2) T and B cell immune response to people acutely infected with HBV, 3) Developing a neutralizing antibody assay to study the antibody response to HBV, and 4) Using genome wide association stud (GWAS) data to find human genetic variants that are associated with HBV recovery or persistence. For our HCV studies we also use GWAS data to find host genetic variants associated with clearance or persistence. We are also looking at how HIV therapy alters the immune response to HCV in those with HIV-HCV co-infection.
