The KiTZ and the Clinic for Pediatric Oncology, Hematology and Immunology of the Heidelberg University Hospital also focus on blood disorders, whether they are malignant or non-malignant. Of the malignant blood diseases, the focus is particularly on T-cell leukemia (research group leukemia), of the non-malignant anemia (research group anemia) and iron metabolism disorders (research group iron metabolism). The research group mRNA metabolism investigates molecular mechanisms that play a role in the development of coagulation disorders and immune defects.
