Research Overview
Focus
The Institute for Experimental Cellular Therapy is dedicated to the transplantation of allogeneic tissues, in particular of hematopoietic stem cells (HSC). HSC transplantation represents the only possibility of definitive cure for many patients affected by tumors of the blood system, such as leukemia, and its clinical application is increasing around the world. Besides offering diagnostic services for allogeneic HSC transplantation, the Institute for Experimental Cellular Therapy is focused on translational research aimed at unraveling the biological mechanisms underlying the clinical success or failure of allogeneic HSC transplantation.
- Cellular and humoral alloreactivity and its role in transplantation
- Molecular and functional polymorphism of the HLA system and immune-related genes

Neue Forschungserkenntnisse zu Blutkrebs Gewebeverträglichkeit beeinflusst weiterhin die Überlebensrate nach Blutstammzelltransplantation
[09.09.2024] Die Transplantation von Blutstammzellen gesunder Spender:innen kann für Patient:innen mit aggressiven Blutkrebserkrankungen lebensrettend sein. Bei dieser Behandlung können im Transplantat vorhandene Immunzellen der Spender:innen die gesunden Gewebe des Patienten schädigen. Um dieses Risiko zu vermindern, erhalten die Patient:innen nach der Transplantation immunsupprimierende Medikamente, darunter seit jüngster Zeit vermehrt das hochwirksame Cyclophosphamid. Auch unter dieser Behandlung trägt eine zwischen Spender:in und Empfänger:in fein abgestimmte Verträglichkeit von Gewebemerkmalen entscheidend zur Überlebensrate der Betroffenen bei. Das zeigt eine von Forschenden der Medizinischen Fakultät der Universität Duisburg-Essen und der Universitätsmedizin Essen geleitete internationale Studie, die kürzlich im Journal of Clinical Oncology veröffentlicht wurde.


Neuer Schlüssel zum Therapieerfolg entdeckt Stammzellen gegen Blutkrebs
[30.01.2023] Eine Knochenmarktransplantation, oder medizinisch korrekt: die Transplantation von Blutstammzellen, bietet für viele Patient:innen die einzige Chance, von einer Leukämie langfristig geheilt zu werden. Um den Kampf gegen den Blutkrebs gewinnen zu können, müssen die transplantierten Immunzellen die Leukämie unter Kontrolle halten, möglichst ohne gesunde Gewebe anzugreifen. Hierzu müssen die Spender:innen der benötigten Stammzellen sehr gründlich ausgewählt werden, damit ihre Gewebemerkmale so gut, wie es geht, mit denen des oder der Erkrankten übereinstimmen. Dass neben den Gewebemerkmalen aber auch die an sie gebundenen Eiweißmoleküle ganz wesentlich den Therapieerfolg beeinflussen, haben Forschende der Medizinischen Fakultät der UDE nun herausgefunden.
