Abstract:
The interaction of thrombin with platelet glycoprotein Ibalpha (GPIb alpha) is required for optimal platelet activation. The crystal structures of platelet GPIb alpha bound to thrombin reported by Dumas et al. and Celikel et al. both reveal the simultaneous interaction of GPIb alpha with thrombin exosites I and II but differ markedly regarding how the two proteins interact. The possible consequences on thrombus formation of thrombin interacting with GPIb alpha are discussed in light of these new data.

Formation of the Platelet Plug
As the injured blood vessel contracts, endothelial cells undergo contraction, revealing collagen fibers in the basement membrane and underlying connective tissue. Furthermore, the plasma membrane of endothelial cells becomes adhesive, preparing the site for platelet adhesion. Platelets...

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...
Coagulation
During the coagulation phase, clotting factors, or procoagulants, play a vital role in initiating and progressing the coagulation cascade. This cascade is a series of reactions...
