TP07: Dissecting NK cell-mediated immune responses against hepatitis B virus and hepatitis C virus infection

Natural Killer (NK) cells are cytotoxic and cytokine-producing innate immune cells that are highly enriched among lymphocytes in the liver and can mediate efficient antiviral immune responses. It is the aim of our project to dissect the mechanisms of the interaction of NK cells with HBV or HCV infected liver cells and the influence of the microenvironment in in vitro co-culture systems and with patient derived cells. Our studies should reveal novel knowledge of NK cell function/dysfunction in HBV and HCV infection that could potentially unravel novel targets for therapy.
