Heidelberg is responsible for coordinating the research field "HIV" at the DZIF. In order to control HIV infections, DZIF researchers at this location research factors of the innate immune system and identify DNA sites for viral DNA integration. Alongside HIV, Heidelberg co-coordinates the research areas "Hepatitis", "Malaria" and "Infections of the Immunocompromised Host". The Heidelberg scientists also coordinate the DZIF-wide translational infrastructur "Biobanking", with a focus on establishing tissue biobanks. Research activities concentrate on imaging infections in systems of increasing complexity: from clonal cells to mixed cell populations, whole tissue models and even small animal models.
