High shear forces can induce structural changes in the shape of the von Willebrand factor (VWF) molecule, making it more sensitive for ADAMTS-13, a specific VWF protease. This leads to proteolysis of the highest-molecular-weight multimers, which are the most effective in platelet-mediated hemostasis under conditions of high shear stress. The ...
