Early onset amyloid lesions lead to severe neuritic abnormalities and local, but not global neuron loss in APPPS1 transgenic mice
چکیده انگلیسی
APPPS1 transgenic mice develop amyloid-β 42 (Aβ42)-driven early-onset cerebral β-amyloidosis. Stereological analysis of neocortical neuron number in groups of 2-, 10-, and 17-month-old APPPS1 mice did not reveal any changes compared with wild-type control animals despite massive amyloid-β (Aβ) load and disrupted cytoarchitecture. However, in subregions with high neuron density such as the granule cell layer of the dentate gyrus, modest but significant neuron loss was found, reminiscent of findings in previously published mouse models with late onset cerebral β-amyloidosis and predominant amyloid-β 40 (Aβ40) expression.
