MATERIALS AND METHODS: Detection of apoptotic nuclei in temporal lobe, brain stem, medulla oblongata, hippocampus and basal ganglia from one young CADASIL patient was performed by terminal deoxynucleotidyl transferase (TdT)-mediated dUTP nick end-labeling (TUNEL).
RESULTS: Our results showed a great involvement of glial cells in apoptotic cell death in the majority of the brain regions examined; neuronal apoptosis was significantly present only in the brain stem region.
CONCLUSIONS: We hypothesized that in the early stages of the disease neuronal involvement of apoptosis is limited to the cells of the brain stem, sparing the cortical area which is involved in neuronal apoptosis and cognitive decline later. | | Language | eng | | Pub Type(s) | Journal Article
