happ-SL x hTau, APP751-SL x TAU441 V337M R406W C57BL/6 x DBA MAPT, APP APP KM670/671NL (Swedish), APP V717I (London), MAPT V337M (Seattle Family A), MAPT R406W Cross of two models from QPS: (1) APP751SL, which overexpresses mutant human APP (isoform 751) with the Swedish (K670N/M671L) and London (V717I) mutations under the control of the brain-specific Thy1 promoter, and (2) THMT, which overexpresses human MAPT (441) with the V337M and R406W mutations under the control of Thy1. MAPT: Transgenic; APP: Transgenic Alzheimer's Disease Plaques start at 3-6 months. Some acceleration of amyloid deposition in the amygdala as compared to the hAPPSL single transgenic; detected in bigenic animals by 3 months vs 6 months. Cognitive impairment at 3 months demonstrated by the Morris Water Maze. Eyes appear smaller compared to wild-type mice, but pupillary reflex, eye blink reflex, and visual test performance are normal.

TgTauR406W B6SJL/F1; backcrossed to C57BL/6J MAPT MAPT R406W Human 4-repeat tau cDNA with the R406W mutation containing myc and FLAG tags at N-and C-terminal ends, respectively, and driven by the CaMK-II promoter. MAPT: Transgenic Frontotemporal Dementia, Alzheimer's Disease Argyrophilic and congophilic tau inclusions in neurons of the forebrain with age. Detectable with Congo red, thioflavin-S and Gallyas silver stain. Congophilic tau inclusions also in the hippocampus and amygdala. Mainly straight tau filaments. Impairments in contextual and cued fear conditioning at 16–23 months compared with wild-type littermates. No detectable sensorimotor deficits. No differences from wild-type in body weight, sensorimotor reflexes (acoustic startle response), or motor coordination (accelerating rotarod and pole tests).  Attenuation of the Schaffer collateral-evoked neural response in hippocampal slices. Decrease in prepulse inhibition. Higher mortality. Unknown. Tatebayashi et al., 2002 Yes
RW Tg mice C57BL6 x C3H, maintained in B6C3 background MAPT MAPT R406W Human tau with the R406W mutation driven by the mouse prion promoter. MAPT: Transgenic Frontotemporal Dementia Age-dependent increase in tau. Neurofibrillary-tangle-like pathology (filamentous intraneuronal tau aggregates), especially in the hippocampus. Neurodegeneration. Extensive gliosis in the brain and spinal cord. Progressive motor weakness with advancing age, as demonstrated by dystonic movements of the hindlimbs when lifted by the tail. Altered microtubule binding and slow axonal transport of tau. Reduced lifespan. Unknown. Zhang et al., 2004 No
Thy-1 mutated human tau, TAU 441, hTAU441, TAU441 V337M R406W C57Bl/6xDBA MAPT MAPT V337M (Seattle Family A), MAPT R406W Transgene consists of human MAPT Tau441 (2N/4R) with mutations V337M and R406W under control of the Thy1 promoter. MAPT: Transgenic Alzheimer's Disease Increased total tau, and phosphorylated tau (Thr181, Ser199, Thr231) in amygdala and hippocampus starting at 3 months. Spatial memory deficits starting at 5 months (Morris water maze). Olfactory deficits at 5 months (Buried food test). No motor deficits (rota rod, beam walk) or depressive behavior (forced swim test). Olfactory deficits. QPS-Austria Flunkert et al., 2013 Yes
