Abstract

Many neurodegenerative diseases, including Alzheimer's, originate from the conversion of proteins into pathogenic conformations. The microtubule-associated protein tau converts into β-sheet-rich amyloid conformations, which underlie pathology in over 25 related tauopathies. Structural studies of tau amyloid fibrils isolated from human tauopathy tissues have revealed that tau adopts diverse structural polymorphs, each linked to a different disease. Molecular chaperones play central roles in regulating tau function and amyloid assembly in disease. New data supports the model that chaperones selectively recognize different conformations of tau to limit the accumulation of proteotoxic species. The challenge now is to understand how chaperones influence disease processes across different tauopathies, which will help guide the development of novel conformation-specific diagnostic and therapeutic strategies.
