Mechanistic description

Synthetic glycan mimetics that competitively bind to tau vesicle surface receptors could prevent pathological vesicle fusion and tau spreading between neurons. These molecular decoys would act as competitive inhibitors of disease progression.

Mechanism / pathway

  1. MAPT
  2. neurodegeneration
