| Research Abstract |
CADASIL is the most common hereditary small vessel disease that is characterized by recurrent subcortical ischemic strokes and ultimately vascular dementia. It is linked to dominant mutations in the human NOTCH3 gene, which is primarily expressed in vascular smooth muscle cells (VSMCs) of the vessel wall. Pathogenic mechanisms remain unclear by the lack of a good animal model. Here, we generated a knock-in (KI) mouse model for one of the CADASIL mutations and investigated this mouse to elucidate whether the pathological hallmarks of CADASIL are observed with mutant Notch3. Further, we examined the effect of chronic intermittent restraint stress on the pathogenesis of CADASIL using this mouse.
