Project Description

TP20: Impact of interferon-stimulated genes on virus-specific CD8+ T cells and NK cells in viral hepatitis

The overall aim of this project is to identify the role of Interferon-stimulated genes (ISGs) in T-cell and NK-cell differentiation and function in order to determine the impact on the failure of the cytotoxic immune response in chronic viral hepatitis. For this, we will determine ISG signatures and the responsiveness towards interferons of different virus-specific CD8+ T-cell and NK-cell subsets in viral hepatitis by RNAseq, ATACseq and high-dimensional FACS analyses complemented by in vitro assays following gain- and loss-of-function experiments.
