The Department of Transplantation and Infection Immunology was founded in 2009 as an interdisciplinary department to combine basic research with patient-oriented research. The scientific focus is on the regulation of cellular immune responses against clinically relevant pathogens and against donor tissue after organ transplantation. Another focus is on the monitoring of infectious complications under immunosuppression and on the quantification of the efficacy of immunosuppressive drugs.

The department includes a research laboratory as well as a diagnostic area offering the quantification of specific T cells against the cytomegalovirus as well as against the causative agent of tuberculosis using state-of-the-art technology. The scientific work is supported by the German Research Foundation (DFG), the Else-Kröner-Fresenius Foundation, the German José Carreras Leukemia Foundation, the Roche Organ Transplant Research Foundation (ROTRF), the European Union (EU), the German Federal Ministry of Education and Research (BMBF) and Staatskanzlei des Saarlandes.


EU Project HORUS approved

Within the HORIZON 2025 program, our department is a partner in the international HORUS project to study cytomegalivirus infection after organ transplantation. The project is coordinated by Dr. Hannah Kaminski from the University of Bordeaux. [Interested in more details?]

New paper

Interesting! Ipsilateral or contralateral side in second vaccination?
Medical student Laura Ziegler investigated this question in her medical doctoral thesis. The work was done in close cooperation with the occupational health departments of Saarland University Hospital and Robert Bosch GmbH. Congratulations on the publication!
