ABSTRACT
C3 nephritic Factor (C3NeF) is autoantibody that binds neoepitopes of the C3 convertase C3bBb, resulting in a stabilization of the enzyme. First functional characterizations of C3NeF were performed by hemolytic assays using preactivated sheep erythrocytes (bearing C3b). Sheep erythrocytes are beforehand sensitized with an anti-sheep red blood cell stroma antibody produced in rabbit (hemolysin). Sensitized sheep erythrocytes will initiate cascade complement activation via the classic pathway, followed by alternative pathway amplification loop, resulting in C3b covalent binding to cell surface. Sheep erythrocytes bearing C3b permit the alternative pathway exploration, in particular decay of alternative pathway C3 convertase.
