| Outline of Final Research Achievements |
We found a large family with congenital thrombocytopenia and arteriovenous thrombosis. As a consequence of genetic analysis, we could identify mutation of a G protein-coupled receptor, GPR25. Transgenic mice bearing this mutation showed thrombocytopenia in some mice, but not in others, suggesting inconclusive evidence. We successfully generated anti-GPR25 monoclonal antibody and our antibody experiments confirmed the expression of the GPR25 protein on the platelet surface. Moreover, functional analysis revealed that patient’s platelets had enhanced platelet aggregation and formed firm aggregates in agonist-induced platelet aggregation.
