The research areas Hepatitis and Infections of the Immunocompromised Host are co-managed from Heidelberg. Furthermore, Heidelberg scientists coordinate the DZIF-wide biobanking unit - since 2021 part of the DZIF infrastructure Bioresources, Biodata and Digital Health - with a focus on tissue banks. Methodologically, one of the focal points of Heidelberg´s activities is imaging techniques for visualising infection in systems of varying complexity: from clonal cells and mixed cell populations to organs and animal models. Research on HIV is also conducted here.
