患有唐氏综合症(21三体)的人患阿尔茨海默病的风险大大增加,其特征是大脑中积累的淀粉样蛋白-β斑块。淀粉样蛋白-β是由21号染色体上的APP基因编码的淀粉样前体蛋白加工的产物。在唐氏综合症中,淀粉样蛋白β积累的第一个部位是内小体,内小体生物学的变化在阿尔茨海默病早期就发生了。在这里,我们确定从唐氏综合症小鼠模型中分离的原代小鼠胚胎成纤维细胞是否可以用于研究内体和APP细胞生物学。我们报告说,在这个细胞模型中,内吞体数、大小和APP处理没有改变,可能是因为APP在模型中对剂量不敏感,尽管App有三个副本。
Individuals who have Down syndrome (trisomy 21) are at greatly increased risk of developing Alzheimer’s disease, characterised by the accumulation in the brain of amyloid-β plaques. Amyloid-β is a product of the processing of the amyloid precursor protein, encoded by the APP gene on chromosome 21. In Down syndrome the first site of amyloid-β accumulation is within endosomes, and changes to endosome biology occur early in Alzheimer’s disease. Here, we determine if primary mouse embryonic fibroblasts isolated from a mouse model of Down syndrome can be used to study endosome and APP cell biology. We report that in this cellular model, endosome number, size and APP processing are not altered, likely because APP is not dosage sensitive in the model, despite three copies of App.
