Clinical transplantation surgery and experimental immunology

The research group is focused on mechanisms that regulate the immune activity in healthy individuals and in patients suffering for immune related diseases and conditions such as rejection after organ transplantastion, autoimmunity, immunodeficiency, chronic infections and cancer.

About the group

The research group is also working on clinical issues related kidney, liver and pancreas transplantation. Surgical technique, surgical complications, patient- and graft survival, graft function and preservation and donor criteria are important areas of the research Projects.

The main goals in experimental immunology is to map and identify new therapeutic targets. We use biochemical, cellular biological og functional immunological methods to investigate intracellular signal transduction pathways in mainly T cells. Our main goals in clinical transplantation surgery are to improve the prognosis and patient survival in kidney, liver and pancreas recipients and to optimize graft function. We also aim to improve the availability of donor organs by using extended criteria for donor selection and increase the quality of the organs by new preservation Methods.
