Generation of nanobodies with conformational specificity for tau oligomers that recognize tau aggregates from human Alzheimer's disease samples.

Tauopathies are neurodegenerative diseases that involve tau misfolding and aggregation in the brain. These diseases, including Alzheimer's disease (AD), are some of the least understood and most difficult to treat neurodegenerative disorders. Antibodies and antibody fragments that target tau oligomers, which are especially toxic forms of tau, are promising options for immunotherapies and diagnostic tools for tauopathies.
