Neuropathology

Increased total tau and phosphorylated tau species (Thr181, Ser199, Thr231) in the amygdala and hippocampus starting at three months.

Cognition/Behavior

Spatial memory deficits starting at five months by the Morris water maze. Olfactory deficits at five months indicated by the buried food test. No motor deficits (by rotarod, beam walk) or depressive behavior as indicated by the forced swim test.

Modification Details

Transgene consists of human MAPT Tau441 (2N/4R) with mutations V337M and R406W under control of the Thy1 promoter.
