Chronic viral hepatitis

Hepatitis virus – host interaction (Prof. Dr. Ulrike Protzer)

The human hepatitis B virus (HBV) is a small, enveloped DNA viruses (family hepadnaviridae) whereas the hepatitis C virus is an enveloped plus-strand RNA virus (family flaviviridae) and the hepatitis delta virus (HDV) is a viroid co-existing with HBV. Although these viruses are rather diverse, all cause acute and chronic viral hepatitis. Chronic viral hepatitis is a major public health problem with about 240-300 million chronic HBV, about 150-170 million chronic HCV and about 30 million chronic HDV carriers worldwide who are at high risk of developing liver cirrhosis and hepatocellular carcinoma. Since strategies to eradicate HBV and HDV and treatments for consequent liver disease are still very limited, our focus is on hepatitis B cure. As a prerequisite for developing these, we established infection systems that allow studying (and interfering with) all steps of virus replication.

The main focus of our group is to understand in molecular detail the interaction of HBV with its host and its host cell, the hepatocyte. Hereby, we investigate which cellular pathways are involved in the control of HBV replication, which viral proteins may counteract them and how HBV is activated or inactivated by immune mediators or metabolites. In addition, we use the advanced understanding of HBV molecular biology for developing HBV-based viral vectors for a liver directed gene transfer. Since hepatitis C virus infected individuals often develop type II diabetes, we investigate how the virus may interfere with insulin signaling. We also want to contribute to the molecular understanding of hepatocarcinogenesis, which develops on the basis of chronic hepatitis B or C virus infection. Based on the knowledge we acquire, we develop novel targeted therapies and immunotherapies, and test them in preclinical mouse models we have established.

Head of the group

Ulrike Protzer studied medicine and finished trainings as a specialist for Internal Medicine with a focus on hepatology and infectious diseases and as a specialist for in Medical Microbiology, Virology and Infection Epidemiology working with Karl-Hermann zum Büschenfelde, Guido Gerken, Georg Kräusslich and Martin Krönke. She did her scientific postdoctoral training with Heinz Schaller at the Center for Molecular Biology Heidelberg (ZMBH, Molecular Biology of Hepatitis B Viruses), where she also passed her “habilitation”. At the University of Cologne she was appointed as a junior group leader before she was became chair of virology at the Technische Universität München heading the Institute of Virology there and at the Helmholtz Zentrum München.
