Tau Seeding Models

Recapitulate the key structural features and spreading of tau pathology found in the brain of Alzheimer’s disease and other tauopathy patients

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 pathology in AD and other Tauopathy patients (frontotemporal dementia (FTD), frontotemporal lobar degeneration, corticobasal degeneration, progressive supranuclear palsy, Pick’s disease) is strongly associated with neurodegeneration and clinical symptoms. 

Injection of brain extract from Tauopathy patients in the mouse brain locally induces Tau pathology. The induced Tau pathology strongly mimics the lesions found in human AD and other Tauopathy patients and accordingly spreads to other brain regions.  

InnoSer has extensive preclinical research experience with Tau seeding using AD patient-derived brain extracts in different Tau transgenic mice. Brain extracts from other Tauopathies can also be used, mimicking the unique features of Tau pathology in these diseases. The choice of the patient brain source depends on the Tauopathy of interest.  

Take advantage of InnoSer’s preclinical research expertise in modelling Tau pathology, flexibility, and collaborative approach for your research. Our in-house neurology experts have long-standing experience with modelling Tau pathology in vivo and are happy to help guide your decision on study design fit for your current research goals.  

Tau seeding models key characteristics:

  • Human brain-derived or recombinant Tau aggregates 
  • Injections in transgenic or humanized Tau mice
  • Tau seeding in amyloid models allows simultaneous modelling of both AD pathologies.
  • Injection of Tau seeds in transgenic Tau mice with FTD-related mutations leads to rapid and aggressive induction and propagation of Tau pathology.

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.
