Abstract

Significance: The aggregation of α-synuclein (aSyn) is a pathological hallmark of Parkinson’s disease. Here we show that the enzymatic component of the innate inflammation system, known as caspase-1, hydrolyzes aSyn, rendering it aggregation-prone.

Claims the paper makes

We couldn’t retrieve this paper’s full text, so its claims and self-check weren’t run. The registry and citation checks still apply.

Claims other papers make about this one

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • H. pylori-induced inflammatory environment could promote α-synuclein expression, misfolding, and aggregation, which subsequently triggers further gut dysbiosis, inflammation, and luminal hyperpermeability initiating a viscous positive feedback cycle.

    “This could create an inflammatory environment that promotes α-synuclein expression, misfolding, and aggregation which subsequently triggers further gut dysbiosis, inflammation, and luminal hyperpermeability initiating a viscous positive feedback cycle [113–117].”
  • Injection of endotoxin into mice induces α-synuclein production and aggregation, as well as loss of dopaminergic neurons in the substantia nigra.

    “injection of endotoxin into mice induces α-synuclein production and aggregation, as well as loss of dopaminergic neurons in the substantia nigra.”

  • Endotoxin may promote the production or aggregation of amyloid β, tau and α-synuclein.

    “Endotoxin may also promote the production or aggregation of amyloid β [66–68], tau [68, 69] and α-synuclein [70, 71].”

  • Endotoxin increases α-synuclein production by macrophages and drives α-synuclein fibrillization.

    “Endotoxin increases α-synuclein production by macrophages [100] and drives α-synuclein fibrillization [70, 71].”

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.
