Remarkably, Iloprost at 1 μg/kg, a low dose that did not affect arterial thrombosis or bleeding time, was able to significantly relieve anti‐GPIbα antibody‐induced platelet clearance, while moderate (4 μg/kg) or high (10 μg/kg) doses of Iloprost did not exert further enhancement (Figure 7G). Here, GP1BA is linked to Arterial thrombosis.
