Antiphospholipid syndrome: an overview.
نویسنده
چکیده
Antiphospholipid antibodies are a heterogeneous group of autoantibodies that are detected by immunoassays and functional coagulation tests. The antigenic targets are negatively charged phospholipids and serum phospholipid-binding proteins. The latter antibodies are frequently associated with thrombosis, fetal loss and other clinical manifestations of the antiphospholipid syndrome. These antibodies are felt to be etiologically important in the syndrome, although the precise pathogenic mechanisms are still being determined. Proposed mechanisms include antibody-mediated interference with coagulation homeostasis, activation of platelets and endothelial cells and a T-cell immune response to serum phospholipid-binding proteins. The mainstay of therapy is anticoagulation, whereas immunosuppression is ineffective.

متن کاملRevisiting Beta 2 Glycoprotein I, the Major Autoantigen in the Antiphospholipid Syndrome
Beta 2 glycoprotein I (β2GPI) is a single chain 50 kDa highly glycosylated glycoprotein at an approximate concentration of 4 μM in cells. The abundance of this protein in plasma and its high state of preservation indicate the important role of this protein in mammalian. In addition, β2GPI has a particular structure in the fifth domain, and is categorized as the major antigen recognized by autoa...

Antiphospholipid syndrome is an autoimmune condition characterized by recurrent vascular thrombosis, pregnancy loss and thrombocytopenia associated with moderate to high levels of antiphospholipid antibodies. Most of clinical features are results of thrombotic phenomena. The pathophysiologic basis ot this syndrome is still unknown. the diagnosis of this syndrome is made by combination of clinic...
