Abstract:
The antiphospholipid syndrome (APS) is a disorder which is characterized by the presence of autoimmune antiphospholipid antibodies (APL) and increased risk of thrombosis and fetal loss. APL are associated with recurrent abortions in APS patients and participate in the pathogenesis of venous or arterial thrombosis, although the underlying mechanisms are poorly understood. Antigens that are targeted by APL include beta 2 glycoprotein I and prothrombin. Pathological mechanisms of APL encompass inhibition of natural anticoagulants (protein C system, tissue factor pathway inhibitor, and annexin A5), inhibition of the fibrinolytic system, activation of endothelial cells, monocytes and platelets, and complement activation. In this review, we discuss the main targets of APL and prothrombogenic mechanisms of APL.

Extrinsic and Intrinsic Pathways of Hemostasis
The Extrinsic Pathway
The extrinsic pathway of coagulation is typically initiated by tissue damage that exposes blood to tissue factor (TF), a protein released by the damaged tissue cells outside the blood vessels—this interaction with TF triggers biochemical reactions involving specific clotting factors. The key player here is Factor VII, which forms a...
