Anti-ADAMTS13 autoantibody immunoprofiles in the Japanese iTTP cohort. Immunoprofiles were formed based on the presence or absence of anti-M, anti-DT, anti-CS, anti-T2-T5, anti-T6-T8, and anti–CUB1-2 autoantibodies. The green and red cells indicate the presence and absence of anti-M, anti-DT, anti-CS, anti-T2-T5, anti-T6-T8, and anti–CUB1-2 autoantibodies, respectively (left graph). The percentage of patients with a specific immunoprofile is depicted in the right graph. The same profiles were found as the ones described in our previous report based on a mainly Caucasian cohort,¹³ except for profiles 10, 17, 21, 22, 23, 25, 26, 27, 29, 30, and 31. Profiles 34 to 39 (highlighted in orange) were only detected in the Japanese cohort.
