ADAMTS13 and microvascular thrombosis

Abstract: SummaryInteraction between platelet and von Willebrand factor (VWF), a circulating adhesive glycoprotein, is essential for hemostasis under the high shear environments of arterioles and capillaries. If unregulated, this interaction may lead to unwarranted platelet thrombosis ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 motif, number 13), a plasma zinc metalloprotease synthesized primarily in the stellate cells of the liver, cleaves shear stress activated VWF, thereby preventing the oc… Show more

“…Compared to healthy controls, patients with PAD showed higher tissue plasminogen activator antigen, plasminogen activator inhibitor-1 antigen, and D-dimer levels both at rest and after treadmill exercise (41). ADAMTS13 is a protease that cleaves VWF, and imbalance between VWF and ADAMTS13 may favor thrombosis (42). In a study of 595 patients with PAD followed for 3 years, 61% of patients who had acute ischemic CV events were compared to 122 PAD controls without events.…”

“…103 In the absence of additional stimulation, platelets disengage from the vessel wall in a few minutes and return to circulation. Their release is mediated by cleavage of the VWF by the plasma metalloprotease ADAMTS13 (a disintegrin-like and metalloprotease with thrombospondin type I repeats 13), 104 the enzyme that is lacking in thrombotic thrombocytopenic purpura (reviewed in Tsai 105 ). In the absence of this enzyme, the VWF polymers associate in long strings spanning many endothelial cells to which platelets adhere like beads on a necklace.…”

“…ADAMTS13 (a disintegrin and metalloprotease with thrombospondin type 1 motif, number 13) plays an important role in VWF processing by cleaving the unusually large multimers of VWF originally secreted by endothelial cells and those found contained within platelets (43). A deficiency of ADAMTS13 allows usually large VWF multimers to persist in circulation, resulting in intravascular VWF-platelet aggregation and widespread microvascular thrombosis (44 Figure 3.…”
