This improved model is able to detect tau seeds with specificity towards seeds from 3R+4R tauopathies and can be used to further our understanding of the mechanisms involved in seeded aggregation.

We also used electron cryo-microscopy to structurally characterise the AD-seeded tau filaments from the biosensor cells and determined that they are able to reproduce the Alzheimer tau fold.

In our work we rationally designed a new sensitive HEK-based biosensor cell line that is able to specifically detect tau seeds from 3R+4R tauopathies, such as Alzheimer's disease (AD) and Chronic Traumatic Encephalopathy (CTE).

Seeding biosensor cell line that reproduces the Alzheimer tau fold

The assembly of tau protein into amyloid filaments through templated seeding is believed to underlie the propagation of pathology in neurodegenerative diseases, such as Alzheimer’s disease (AD) and ot...
