Cadasil Vascular Cells is an important component in the neurobiology of neurodegenerative diseases. This page provides detailed information about its structure, function, and role in disease processes.
This page provides comprehensive information about the cell type. See the content below for detailed information.
CADASIL (Cerebral Autosomal Dominant Arteriopathy with Subcortical Infarcts and Leukoencephalopathy) is caused by mutations in the NOTCH3 gene affecting vascular smooth muscle cells and pericytes. These cells show characteristic pathological changes that lead to small vessel disease and vascular dementia.
- R90C (most common)
- C49F, R133C, R141C
- Cysteine substitutions in EGFR repeats
- 34 different mutations described
- Abnormal NOTCH3 accumulation
- Granular osmiophilic material (GOM) deposits
- Smooth muscle cell degeneration
- Basement membrane changes
- Location: Arteriolar walls
- Changes: Degeneration, vacuolization
