INTRODUCTION In a discordant orthotopic xenotransplantation model (pig-to-baboon) donor pigs expressing human decay accelerating factor (hDAF) as a regulator of complement activity were used to prevent hyperacute xenograft rejection (HXR). We investigated a modified immunosuppressive therapy consisting of ERL080 (Novartis Pharma AG, Base, Switzerland),(More)
BACKGROUND Hyperacute xenograft rejection (HXR) is characterized by complement activation and intravascular thrombosis. The pathogenesis of HXR is attributed to antibodies binding to α-Gal-epitopes on the endothelial cells (EC) of the xenograft, activating complement and thrombin-mediated coagulation mechanisms. Our aim was to evaluate the influence of(More)
INTRODUCTION Hyperacute xenograft rejection (HXR) and acute vascular rejection (AVR) after xenotransplantation are triggered by xenoreactive antibodies (XAb) and an activated complement cascade. In a heterotopic (abdominal) xenotransplantation model we combined immunoadsorption (IA, Ig-Therasorb column) and a quadruple immunosuppressive drug therapy in(More)
