Because this line of APP mice develops memory impairments and Aβ plaques at the age of 4 months and 5 months, respectively [26, 27], we followed the behavioral changes and Aβ plaque formation in APP/DcR3, APP, DcR3, and wild-type (WT) littermates, respectively, to determine whether DcR3 modulates the pathogenesis of AD at 6 months after birth. Here, TNFRSF6B is linked to Alzheimer disease.
