Description

To develop a model of Alzheimer's Disease, mice harboring mutant human APP (Swedish double mutation; K670N, M671L) and MAPT (P301L) as well as Psen^tm1Mpm were generated by microinjection of the APP and MAPT transgenic constructs into single cell embryos harvested from mice homozygous for Psen1^tm1Mpm. Southern blot analysis indicated that both transgenic constructs integrated into the same site. Western blot analysis showed APP and MAPT levels to be ~4 fold higher in hemizygous mice and ~6 (APP) to ~7 (Mapt) fold higher homozygous mice, relative to non transgenic mice. Amyloid-Beta peptide (both 40 and 42) was detected in transgenic mice, with greater levels in homozygous mice than in hemizygous mice. Expression was confined to the CNS. Highest steady state levels of proteins were detected in Alzheimer's Disease related regions including the hippocampus and cerebral cortex. Transgenic protein was not detected in the cerebellum. The transgene inserted on Chr 2 causing a 3 bp deletion.
