VIRO

The Institute of Virology (VIRO) research activities focus on the molecular understanding of virus-host interactions. Based on this understanding, we develop and improve therapeutic strategies for viral infections and related diseases.

Viruses are important environmental risk factors to which humans are exposed. The Institute of Virology investigates the molecular and cellular mechanisms behind the persistence and propagation of viruses that cause chronic infections and the potential of these viruses to cause diseases in humans. Unique cell culture and mouse models as well as archived human samples allow us to determine the molecular pathways involved in disease pathogenesis. On the basis of results obtained in molecular studies, we develop novel diagnostic and therapeutic concepts, use viruses as therapeutic tools and create strategies that are intended to prevent viral diseases.

Our scientific interest is to better understand the interaction of hepatitis B (HBV) and C (HCV) virus with their host and to develop new therapeutic strategies to treat chronic viral hepatitis and hepatocellular carcinoma.

The aim of our research is to elucidate the functional role of HERVs during stem cell differentiation and brain development using cutting-edge technologies including advanced CRISPR techniques in combination with human stem cell differentiation, the generation of brain organoids (mini brains in the dish) and bioinformatics analysis of large datasets.

The main focus of our research is the analysis of the phenotype and functional properties of different immune cell populations mainly in the context of clinical trials. By doing so, we are aiming for an in depth understanding of cellular virus-host interactions to support the development of novel therapeutic interventions, e.g. by prediction of biomarker that identifies target engagement and predicts response to therapeutic interventions.

The Deng lab uses an integrative approach combining single-cell technologies, culture-independent techniques, multi-omics, and machine learning to understand the underlying mechanisms of phage-host interactions and their impact on the human host. Ultimately, we aim to develop personalized phage-based treatments against multiple human diseases and conditions.

Our research focus is on the immune response against the Epstein-Barr virus (EBV), and EBV-associated disease. With a better understanding of how immunity against EBV is established, we seek to establish predictive markers for the development and novel strategies for the treatment of virus-associated disorders.
