Modification: MAPT: Transgenic
Disease Relevance: Alzheimer's Disease
Strain Name: N/A
Genetic Background: C57Bl/6xDBA
Availability: The CRO QPS-Austria offers research services with this line.
Increased total tau and phosphorylated tau species (Thr181, Ser199, Thr231) in the amygdala and hippocampus starting at three months.
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.
Transgene consists of human MAPT Tau441 (2N/4R) with mutations V337M and R406W under control of the Thy1 promoter.
When visualized, these models will distributed over a 18 month timeline demarcated at the following intervals: 1mo, 3mo, 6mo, 9mo, 12mo, 15mo, 18mo+.
Tangles at 4 months and progress with age.
Cognitive impairment by 5 months as measured by the Morris Water Maze.
