Summary
This project comprises immunological and virological analyses within a prospective clinical study of Rituximab (Rtx)-treated blood group incompatible living donor (LD) renal transplant recipients compared to blood group compatible LD recipients without Rtx induction, and of living donor compared to deceased donor renal transplant recipients treated with tacrolimus (Tacr)/mycophenolate sodium (MPS). Aim of this project is to assess short- and long-term effects of immunosuppressive therapy (Rtx induction) and of living donation on immunological and histological parameters of graft outcome and on viral replication (BK virus (BKV), JC virus (JCV), cytomegalovirus (CMV), Epstein Barr virus (EBV)) with the potential to improve long-term graft outcome and to enable risk estimation of virus disease.
