Research description

Our group has a long-term interest in exploring the function of human immune reaction in cancer and infectious diseases. 

Within the field of cancer, we study NK cell reactivates towards tumor cells and explore the potential of using NK cells in therapeutic settings. Within the field of infectious diseases, we explore immune reactions towards flavivirus infections (in particular TBEV, JFV, and JEV), hantavirus infections, and SARS-CoV-2 infections. With respect to flavivirus infections and SARS-CoV-2 infections we also explore vaccine responses in humans vaccinated with existing vaccines.
