Research group(s)

Research interests

Our group focuses on the molecular understanding of cancer.  In the area of tumor immunology we investigate the induction and the consequences of immunogenic cell death. We believe that this will lead to novel concepts in immunotherapy of cancer.  We intend to learn from our patients correlating immungenic parameters of the tumor microenvironment in colorectal cancer with the course of the disease.  Having an expertise in genetic engineeing of influneza virus we developed the first oncolytic influenza virus and futher intend to optimze viral vectors and its production to allow clinical use. Our focus on an RNA viruses led to a specific interest on the impact of cell death inducing receptors in viral and malignant disease. Here we lately described novel regulatory aspects in toll-like receptor 3 signalling

Our interest in virus-cancer cell interaction also led us to the discovery that retroviral like elements such as the LINE1 retrotransposons, which comprise 17% of our genome, are involved in telomere regulation. This created a novel focus of our research on the impact of telomers and cell death.
