Disease-specific tau polymorphs are associated with unique protein networks across proteinopathies.

Distinct tau polymorphs in Alzheimer’s, PSP, and DLB associate with unique protein networks, with 493 high-confidence interactors revealing disease-specific patterns.

• Why it matters: Understanding how tau aggregates interact differently across tauopathies is crucial for unraveling disease heterogeneity and developing targeted therapies, yet these interactions are poorly characterized.
• What they did: The study used interactome profiling of tau aggregates from brain samples, identifying specific protein interactors through machine learning and mass spectrometry, highlighting disease-specific interaction signatures.
• The result: Findings demonstrate that tau conformations are linked to distinct protein networks, enabling disease classification with few features and offering molecular insights into tauopathy diversity.
