Research interest

Immune responses to viral pathogens are tightly regulated. During acute viral infections, a strong and multi-specific T cell response is required to control and eliminate the pathogen. Subsequently, the majority of T cells undergo apoptosis, to protect the host from immune mediated damage, and a small subset of cells turn into pathogen-specific memory cells. The processes that mediate T cell expansion, contraction and survival are strongly influenced by various co-stimulatory molecules. Unfortunately, viruses such as Hepatitis C Virus (HCV) and Hepatitis B Virus (HBV) have the ability to establish persistence and in such cases, T cells are often functionally impaired or entirely lost. However, the signals that regulate T cell survival and function in chronic viral hepatitis are incompletely understood. We are interested in the characterization of these signals in the context of acute and chronic viral hepatitis B, C and E with a particular focus on the role of co-stimulatory molecules and virus-specific CD4 T cells. In addition, T cell responses to viruses and vaccinations are severaly impaired in the context of chronic liver disease and in patients after liver transplantation. However, it is still unknown in these scenarios how the virus-specific CD4 T cell repertoire and the signals that govern the differentiation and maturation of T cell responses are altered specifically altered.
