Platelet antigens in varicella associated thrombocytopenia.
Serum IgG or, predominantly, IgM antibody binding to electrophoretically separated normal platelet membrane protein antigens were detected by immunoblotting in five children with thrombocytopenia associated with varicella. Glycoproteins GPIb, GPIIb, GPIIIa, and other 25-260 kilodalton (kDa) proteins were identified as target antigens, suggesting a transient autoimmune mechanism causing the thro...

متن کاملHeparin-associated thrombocytopenia: antibody binding specificity to platelet antigens.
Sera from four patients with heparin-associated thrombocytopenia (HAT) were evaluated by a quantitative enzyme-linked immunosorbent assay (ELISA) to detect heparin-dependent serum platelet-bindable immunoglobulin (S-PBIg) and by Western blotting and immunoprecipitation to investigate the specificity of the antibody binding. All HAT sera showed mildly increased S-PBIg (mean, 7.8 fg per platelet;...
متن کاملHuman platelet antigens polymorphisms: Association to primary immune thrombocytopenia in the Iranian patients
Background: Human platelet antigens (HPAs) are part of platelet GP complexes have the potential to contribute to the autoantibody production. Moreover, these antigens demonstrate different patterns of distribution on different ethnic groups and variation in some types of diseases. This study was objected to determine the incidence of HPA-1 to -5 and -15 polymorphisms in the Iranians suffering f...
متن کاملHuman platelet antigens and primary immune thrombocytopenia☆
Primary immune thrombocytopenic purpura (ITP) is an acquired immune-mediated disorder characterized by transient or persistent decreased platelet count (<100 × 109/L) that affects children and adults in the absence of other underlying causes.1,2 The low platelet count results from platelet destruction by antiplatelet autoantibodies associated to causes such as insufficient platelet production, ...
