Mechanistic description

Electrostatic bridging by glycans and low-abundance proteins preserves disease-relevant fibril architecture.

Mechanism / pathway

  1. SNCA
  2. neurodegeneration

Evidence for (5)

  • Heparan sulfate proteoglycans in alpha-synuclein aggregation and Parkinsonism.

    PMID:35790300 2022 Acta Neuropathol

  • Glycosaminoglycans modulate alpha-synuclein fibrillation kinetics.

    PMID:32824376 2020 Acta Neuropathol

  • CSF glycosaminoglycans as biomarkers of synucleinopathy.

    PMID:34626424 2021 Acta Neuropathol

  • Glycosaminoglycan-binding sites on alpha-synuclein govern aggregation and uptake.

    PMID:35962883 2022 Neurobiol Dis

  • Heparan sulfate modifications in dementia with Lewy bodies CSF.

    PMID:36995304 2023 Acta Neuropathol

Evidence against (1)

  • The mechanism remains too diffuse without isolation of a named molecular species.
