The effect of soluble complement receptor type 1 on hyperacute rejection of porcine xenografts

The use of xenografts (Xgs) from distantly related species to relieve the increasing shortage of organs for clinical transplantation is prevented by the occurence of hyperacute rejection (HAR). This process, in which C activation plays a central role, cannot be inhibited with currently available immunosuppressants. In two clinically relevant xenotransplantation models, this study evaluated the effect of C inhibition using recombinant soluble complement receptor type 1 (sCR1) on HAR
