Outline of Final Research Achievements |
We identified CalDAG-GEFI deficiency and kindlin-3 deficiency by analysis of patients with severe bleeding tendency from their infancy. Using our developed αIIbβ3 activation kinetic assay, we revealed that delayed activation of αIIbβ3 leads to severe bleeding tendency. Furthermore, we analyzed constitutive active αIIb(R995W) knock-in mice, and found that the mice showed macrothrombocytopenia like human subjects. We found that impaired proplatelet formation may responsible for the phenotype. KI mice also showed highly impaired platelet function mainly due to reduced αIIbβ3 expression in platelets.
