Specific combinations of tau phosphorylation, acetylation, and truncation mark assemblies that evade degradation and template after synaptic transfer. Altering the PTM barcode should convert seed-competent tau into transferable but weakly pathogenic tau.
Tau assemblies become seed-competent when their repeat-domain surfaces adopt a conformation that both survives transfer and templates monomeric tau into pathological aggregates. This conformer-specific templating mechanism, supported by structural studies of disease-specific tau filaments, suggests that the exposed repeat domain interface is the critical determinant distinguishing pathogenic from non-pathogenic tau conformations. Non-pathogenic transferred tau lacks this exposed templating inter

Seed-competent tau is likely defined by a compact beta-rich conformer exposing repeat-domain surfaces, a permissive PTM barcode, and packaging into vesicles or synaptic compartments that protect it fr...
