A novel assay quantifies depolarization of synaptosomes from Alzheimer’s cortex, and the authors show that tau released from these samples is unphosphorylated and C-terminal-truncated. Most tau is exosomal, and free-floating tau did not seed aggregation. Seeding activity was lower in tauopathy than AD, and strongly related to amyloid level.
