Here, we generated knock-in mice that express wildtype human Aβ under control of the mouse App locus. Remarkably, changing 3 amino acids in the mouse Aβ sequence to its wild-type human counterpart leads to age-dependent impairments in cognition and synaptic plasticity, brain volumetric changes, inflammatory alterations, the appearance of Periodic Acid-Schiff (PAS) granules and changes in gene expression. In addition, when exon 14 encoding the Aβ sequence was flanked by loxP sites we show that Cre-mediated excision of exon 14 ablates hAβ expression, rescues cognition and reduces the formation of PAS granules. %K Periodic acid-schiff %K Exon %K Cognition %K Mutation %K Gene expression %K Alzheimer disease %K Reacción del ácido peryódico de Schiff %K Exones %K Cognición %K Mutación %K Expresión génica %K Enfermedad de Alzheimer %~
