background: inhibitory antibody to exogenous factor viii (fviii) is a major complication of hemophilia treatment. this study was conducted to determine the prevalence of inhibitor antibody directed against fviii.methods: from may 2010 to may 2011, 52 patients with severe hemophilia a admitted in amirkola children’s hospital were evaluated. those who had abnormal mixing study, antibody against f...
BACKGROUND Antibodies to P. falciparum apical membrane protein 1 (AMA1) may contribute to protective immunity against clinical malaria by inhibiting blood stage growth of P. falciparum, and AMA1 is a leading malaria vaccine candidate. Currently, there is limited knowledge of the acquisition of strain-specific and cross-reactive antibodies to AMA1 in humans, or the acquisition of invasion-inhibi...
BACKGROUND Antibodies that inhibit the growth of blood-stage Plasmodium falciparum may play an important role in acquired and vaccine-induced immunity in humans. However, the acquisition and activity of these antibodies is not well understood. METHODS We tested dialysed serum and purified immunoglobulins from Kenyan children and adults for inhibition of P. falciparum blood-stage growth in vit...
Antibodies play major roles in immunity to malaria; however, a limited understanding of mechanisms mediating protection is a major barrier to vaccine development. We have demonstrated that acquired human anti-malarial antibodies promote complement deposition on the merozoite to mediate inhibition of erythrocyte invasion through C1q fixation and activation of the classical complement pathway. An...
conclusions adsorption of antibodies to bap might interfere with bacterial adhesion to the surface. these antibodies were found to be potent biofilm inhibitors. results injection of bap subunit resulted in high titers of antibody. immunized mice serum had significant (p< 0.001) inhibitory effect on biofilm formation. in vitro inhibition of biofilm formation by a. baumannii was studied at 1:50 c...
Inhibitory antibodies directed against coagulation factor VIII (FVIII) can be found in patients with acquired and congenital hemophilia A. Such FVIII-inhibiting antibodies are routinely detected by the functional Bethesda Assay. However, this assay has a low sensitivity and shows a high inter-laboratory variability. Another method to detect antibodies recognizing FVIII is ELISA, but this test d...
