Alzheimer’s Disease – Transgenic Tau Mouse Models
Test potential therapeutics for Alzheimer’s disease and other Tauopathies in Transgenic Tau mouse models with Tau deposition and the downstream pathological events
Transgenic Tau Mouse Models Key Characteristics
The histopathological hallmarks of Alzheimer’s disease (AD) are extracellular plaques composed of amyloid beta (Aβ) and intracellular inclusions of the protein Tau (neurofibrillary tangles). Tau is encoded by the microtubule-associated protein tau (MAPT) gene. Tau pathology in AD and other Tauopathies such as frontotemporal dementia (FTD) is strongly associated with neurodegeneration and clinical symptoms.Â
Transgenic mouse models overexpressing human Tau with disease associated MAPT mutations display abundant tau pathology, neuroinflammation, neurodegeneration, and behavioural impairments; making them ideal models to test therapeutic interventions for AD and other tauopathies. Transgenic Tau mouse models recapitulating the Tau pathology are suitable for testing compounds for AD, but also a range of other Tauopathies (FTD, frontotemporal lobar degeneration, corticobasal degeneration, progressive supranuclear palsy, Pick’s disease). InnoSer additionally offers Tau seeding models using recombinant and/or patient derived seeds or alternatively APP transgenic mice which recapitulate the amyloid beta pathology of Alzheimer’s disease. However, as each model is unique, modelling distinct pathophysiological aspects of Alzheimer’s disease, we recommend you discuss the most appropriate model with our neurology study directors.Â
✓ P301S (PS19) transgenic Tau mouse model available.Â
✓ TauP301L (JNPL3) Transgenic Tau Mouse Model availableÂ
✓ Tau seeding models (e.g., in PS19, hTau).Â
InnoSer offers expert guidance and a collaborative approach to selecting the best model for your research, as the models we offer present varying degrees of neurofibrillary tangles, neuroinflammation, neurodegeneration, and behavioral deficits. Â
InnoSer’s neurology expert team possesses relevant experience in working with multiple therapy types, including small molecules, peptides, enzymes, oligonucleotides, gene therapy (viral vectors, e.g., AAVs), and immunotherapies (antibody/vaccine immunotherapies).Â

Transgenic Tau Mouse Models Sample Data
Transgenic P301S (PS19) mice show Tau pathology (AT8; phosphorylated Tau) at 8 months of age
Transgenic P301S (PS19) have astro- and microgliosis at 8 months of age.
Thy1-P301L mice show subtle, but significant changes in gait and footprint size on the Catwalk test indicating fine motor skills deficit at 6 months of age; by 10 months or older, these mice show profound motor function deficits
The CatWalk XT (Noldus IT, The Netherlands) is a gait analysis system for quantitative assessment of gait and locomotion in mice. It is the most sophisticated system for the quantification of a wide range of parameters related to footprints and gait in unforced moving animals.
Thy1 (P301S) mice show a progressive decrease in grip strength from 14 weeks of age onwards.
The Grip Strength test assesses neuromuscular function by measuring the peak force a mouse can apply by grasping a bar connected to a force meter. Five trials with front paws are followed by five trials with front and hind paws combined. The median of these five trials is used as a measure of grip strength. The grip strength test is used in Tau transgenic models to longitudinally follow the build-up of toxic Tau protein in the brain stem and spinal cord.

AAALAC Accreditation
InnoSer has earned the AAALAC accreditation, demonstrating our commitment to responsible animal care and use. AAALAC International is a nonprofit organization that promotes the humane treatment of animals in science through voluntary accreditation and assessment programs. Our accreditation is valid for three years, incl. 2023. Read more about the AAALAC accreditation programme here.
Animal Welfare
The 3Rs impact everything from policy and regulatory change to the development and uptake of new technologies and approaches. This is why InnoSer has ongoing commitment and monitoring of these processes. The steps we practice maximize our ability to replace, reduce and refine animal involvement and facilitate our commitment to these principles when it comes to research and drug development.
