    • Provided are non-human mammals comprising a transgenic nucleic acid sequence capable of causing an alteration of expression of Bri2 or Bri3 in the mammal. Also provided are non-human mammals comprising a Bri2 or Bri3 gene under the control of the native Bri2 or Bri3 promoter. Additionally provided are non-human mammals genetically engineered to lack expression of a Bri2 or Bri3 gene. Further, non-human mammals comprising a transgene encoding a Bri2 or Bri3 protein under the control of the αCaMK11 promoter are provided. Non- human mammals comprising a transgene encoding a furin protein are additionally provided. Embryonic stem cells of any of the above-described non-human mammals are further provided. Methods of screening a compound for treatment of a disease characterized by cerebral amyloidosis are additionally provided. Also provided are methods of making transgenic non- human mammals. Nucleic acids capable of causing an alteration of expression of Bri2 or BH3 if transfected into a mouse are additionally provided, as are comprising a sequence capable of causing an alteration of expression of Bri2 or Bri3 if transfected into a mouse.
    • 提供包含能够引起哺乳动物中Bri2或Bri3表达改变的转基因核酸序列的非人哺乳动物。 还提供了包含在天然Bri2或Bri3启动子控制下的Bri2或Bri3基因的非人哺乳动物。 另外提供了遗传工程化以减少Bri2或Bri3基因表达的非人类哺乳动物。 此外,提供了包含编码aCaMK11启动子控制下的Bri2或Bri3蛋白的转基因的非人哺乳动物。 另外提供了包含编码弗林蛋白蛋白的转基因的非人哺乳动物。 进一步提供任何上述非人哺乳动物的胚胎干细胞。 另外提供筛选用于治疗特征为脑淀粉样变性疾病的化合物的方法。 还提供了制备转基因非人哺乳动物的方法。 另外提供了如果转染到小鼠中能够引起Bri2或BH3表达改变的核酸,如同包含能够引起Bri2或Bri3表达改变的序列转染入小鼠的那样。
