Mechanistic description

Enzymatic removal of specific glycan modifications from tau vesicle surfaces using targeted glycosidases could disrupt the molecular interactions that promote tau aggregation, effectively ‘dissolving’ the pathological protein networks by altering their surface chemistry.

Mechanism / pathway

  1. NEU1
  2. neurodegeneration
