Localization of epitopes for human factor VIII inhibitor antibodies by immunoblotting and antibody neutralization.

Human factor VIII(FVIII) inhibitors are pathologic, circulating antibodies that inactivate FVIII. We have examined the location of epitopes on the FVIII protein for inhibitors from hemophilia A and nonhemophilic individuals. The inhibitors were of type I or type II in the kinetics of their inactivation of FVIII. A cDNA clone of human FVIII was used to express defined FVIII protein fragments in ...

In vivo neutralization of a C2 domain-specific human anti-Factor VIII inhibitor by an anti-idiotypic antibody.

Factor VIII (FVIII) administration elicits specific inhibitory antibodies (Abs) in about 25% of patients with hemophilia A. The majority of such Abs reacts with FVIII C2 domain. mAbBO2C11 is a high-affinity human monoclonal antibody (mAb) directed toward the C2 domain, which is representative of a major class of human FVIII inhibitors. Anti-idiotypic Abs were raised to mAbBO2C11 to establish th...

FACTOR V AND VIII INHIBITOR IN PATIENTS WITH COMBINED FACTOR V AND VIII DEFICIENCY

Patients with coagulation factor(s) deficiency who use coagulation therapy are susceptible to forming inhibitors against coagulation factor(s). In this survey we detected factor V and VIII inhibitor in ten patients with combined deficiency of factors V and VIII from north east of Iran (Khorassan province). It was revealed in our survey that eight patients had both factor V and factor VIII i...

Mechanism of factor VIII inactivation by human antibodies. IV. Antibody binding prevents factor VIII proteolysis by thrombin.

Factor VIII activation by thrombin is the result of a proteolytic cleavage of the procoagulant component. These studies examine the effect of human antibody on this activation step in a solid phase immunoadsorbent assay system. Radiolabeled factor VIII antibody: factor VIII protein immune complexes were bound to agarose beads by mouse monoclonal antifactor VIII R:Ag antibody. The incubation of ...
