英文摘要
Anticardiolipin antibodies (aCL) are found in sera of patients with systemic lupus erythematosus (SLE) and related connective tissue diseades. The term, antiphospholipid syndrome, has been proposed to explain the association of aCL and variety of clinical features, including arterial and venous thromboembolic events, recurrent fetal loss and thrombocytopenia.We investigated the role of aCL on the development of thromboembolic manifestations in patients with collagen diseases and obtained the following results.1) beta2-glycoprotein I (beta2-GPI) is essential for the detection of aCL.2) beta2-GPI is a glycoprotein, migrates with an apparent molecular mass of 50KD and forms a unique structure termed "Sushi" domains.3) aCL recognize altered structure of beta2-GPI, but not CL itself.4) A new EIA system for the detection of aCL without CL has been established.Besed on these findings, we concluded that aCL recognize beta2-GPI structure altered by interacting with negatively changed phospholipids or an oxygene modified solid-phase surface.
