| Outline of Final Research Achievements |
The aim of this study is to clarify the pathomechanism of Cerebral Autosomal Dominant Arteriopathy with Sub- cortical Infarcts and Leukoencephalopathy (CADASIL). We hypothized that endocytosis into ligand expressing cell might be disturbed after activation of notch signaling in CADASIL We analyzed the endocytosis of fragment of NOTCH3 extracellular domain into transient Jagged1 expressing cell. The fragment of wild NOTCH3 extracellular domain was found in the Jagged1 expressing cell. In contrast, the fragment of mutant NOTCH3 extracellular domain was not found in the Jagged1 expressing cell. These results supported that endocytosis into ligand expressing cell is disturbed in CADASIL.
