Here we established an AD model with whole‐body insulin resistance without persistent hyperglycemia (APP/IR‐dKI mice) by crossbreeding constitutive knock‐in mice with P1195L‐mutated insulin receptor (IR‐KI mice) and those with mutated amyloid precursor protein (AppNL‐G‐F mice: APP‐KI mice). This evidence concerns the gene INSR and Hyperglycemia.
