    [Thrombotic Thrombocytopenic Purpura --Pathophysiology and Assays of ADAMTS13 Activity].
    Rinsho Byori 2015 Oct;63(10):1228-36
    Thrombotic thrombocytopenic purpura (TTP) is a life-threatening disorder classified with a type of thrombotic microangiopathy (TMA). TTP is caused by a deficiency of von Willebrand factor-cleaving protease called ADAMTS13 (a disintegrin-like and metalloprotease with a thrombospondin type1 motif 13). Low ADAMTS13 levels result in increased ultra-large von Willebrand factor multimers (UL-VWFM), which induce platelet adhesion and thrombosis. Read More
