SCIENTISTS have shown that harmful tau proteins, linked to dementia, spread through the brain like prions. By injecting human proteins into mice, they induced the formation of identical pathological structures.
A fundamental study shows that unfolded tau protein transfers its specific molecular structure to the body's own proteins and generates disease-specific damage patterns in the brain.

Harmful tau spreads like self-propagating prion proteins
Nature, Published online: 30 September 2026; doi:10.1038/d41586-026-02778-wStructural studies support the idea that fibrillized tau protein, a feature of neurodegenerative disorders, acts as a prion-like template to induce misfolding in healthy tau.
Scientists have long suspected troubling parallels between prion diseases and common neurodegenerative pathologies. A new study has confirmed this hypothesis with surgical precision. By injecting poorly folded tau proteins from human brains with Alzheimer's or corticobasal degeneration (CDB) in the brain of wild mice, the brains of wild mice have been shown to ...
