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
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.

Repeat-domain exposure defines seed-competent tau

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...

Clinically, the best product concept is a conformation- or PTM-selective antibody paired with CSF seed amplification or tau-PET enrichment. Broad tau lowering risks interfering with normal microtubule...
