Abstract

Seeding, in the context of amyloid disease, is the sequential transfer of pathogenic protein aggregates from cell-to-cell within affected tissues. The structure of pathogenic seeds provides the molecular basis and enables rapid conversion of soluble protein into fibrils. To date, there are no inhibitors that specifically target seeding of Parkinson’s disease (PD)-associated α-synuclein (α-syn) fibrils, in part, due to lack of information of the structural properties of pathological seeds. Here we design small peptidic inhibitors based on the atomic structure of the core of α-syn fibrils. The inhibitors prevent α-syn aggregation in vitro and in cell culture models with binding affinities of 0.5 μM to α-syn fibril seeds. The inhibitors also show efficacy in preventing seeding by human patient-derived α-syn fibrils. Our results suggest that pathogenic seeds of α-syn contain steric zippers and suggest a therapeutic approach targeted at the spread and progression that may be applicable for PD and related synucleinopathies.

  • Short peptides with altered amino acid sequences that target cross-sectional interfaces have been successfully employed in capping of various amyloid fibrils and inhibition of seeding.

    “Notably, short peptides with altered amino acid sequences that target the cross-sectional interfaces of aggregation-prone regions have been successfully employed in the capping of various amyloid fibrils and the inhibition of seeding (63, 64, 65, 66).”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
