Scientists at Tokyo Metropolitan University have turned to polymer physics to better understand one of the defining features of Alzheimer’s disease: the formation of tau protein fibrils. Their research shows that these fibrils do not form directly. Instead, tau proteins first gather into large clusters, similar to how polymers begin to crystallize. When researchers disrupted these early clusters, fibrils failed to develop in solution.

This finding points to a major shift in how future treatments for neurodegenerative diseases might be designed.
