Paroxysmal nocturnal hemoglobinuria, first described in the late 19th century, is an acquired disorder characterized by hemoglobinemia and hemoglobinuria. The major clinical manifestation of PNH is chronic intravascular hemolysis of various severity. Patients-mostly young adults - may also present with episodes of abdominal or back pain. Common cause of(More)
Recently, a protein isolated from the membrane of human E, the so-called C8 binding protein (C8bp), has been described. C8bp is characterized as a 65-kDa protein that binds to C8 and inhibits the C5b-9-mediated lysis in a homologous system. In the present study, membranes of peripheral blood cells were tested for the presence of C8bp by SDS-PAGE and(More)
The homologous restriction of complement (C) lysis is attributed to membrane proteins: decay-accelerating factor (DAF), C8 binding protein (C8bp) and P18/CD59. Since these proteins are also expressed on peripheral blood cells, species restriction was tested for in the complement-mediated killing of antibody-coated human leucocytes by human or rabbit(More)
