Strain Description
These transgenic mice express the P301S mutant human microtubule-associated protein tau, MAPT, under the direction of the mouse prion protein, Prnp, promoter. The expression of the mutant human MAPT is 5-fold higher than the expression of the endogenous mouse MAPT protein. Hyperphosphorylated, insoluble mutant human MAPT protein in the brain accumulates with age causing decreased microtubule binding. At 3 months of age, transgenic mice exhibit clasping and limb retraction when lifted by the tail, which progresses to limb weakness. By 10 months of age the mice exhibit a hunched back and paralysis, followed by inability to feed. Transgenic mice have a median lifespan of approximately 9 months with approximately 80% dying by 12 months. Histological analysis reveals neuron degeneration in hippocampus and ventricular dilatation (brain atrophy) by 8 months of age, although significant neuron degeneration in the hippocampus occurs at approximately 9 months of age. Neuron loss spreads to the amygdala, neocortex and entorhinal cortex by 12 months of age. Defective translocation of endoplasmic reticulum proteins in affected neurons is observed as early as 3 months of age. The onset of neurofibrillay tangle formation in the neocortex, amygdala, hippocampus, brain stem and spinal cord is 5 months of age. Transgenic mice display neuroinflammation with microglial activation and astrogliosis. The ultrastructure of the neurofibrillay tangle-like lesions detected is similar to that found in brain lesions of human Alzheimer's disease and tauopathy patients. Degradation of synaptic function is significant by 6 months of age. These mice cannot be bred to homozygosity, homozygous females do not mate. This mutant mouse strain may be useful in studies of neurodegenerative tauopathy and Alzheimer's disease.

Strain Development
A transgenic construct containing the P301S mutant human microtubule-associated protein tau, MAPT, under the direction of the mouse prion protein, Prnp, promoter was injected into fertilized B6C3F1 mouse eggs. Founder animals were bred to B6C3F1/J or B6C3F1/Crl mice. The resulting transgenic mice were maintained as hemizygotes on the B6C3F1 background before arriving at The Jackson Laboratory.

The Jackson Laboratory's Genotype Promise

The Jackson Laboratory has rigorous genetic quality control and mutant gene genotyping programs to ensure the genetic background of JAX® Mice strains as well as the genotypes of strains with identified molecular mutations. JAX® Mice strains are only made available to researchers after meeting our standards. However, the phenotype of each strain may not be fully characterized and/or captured in the strain data sheets. Therefore, we cannot guarantee a strain's phenotype will meet all expectations. To ensure that JAX® Mice will meet the needs of individual research projects or when requesting a strain that is new to your research, we suggest ordering and performing tests on a small number of mice to determine suitability for your particular project.
