Abstract

The Parkinson’s disease–associated protein α-synuclein binds to the mitochondrial protein import receptor TOM20, which causes downstream impairment of mitochondrial function.

  • Other in vitro studies revealed oligomeric α-synuclein induced mitochondrial dysfunction and neuronal death through multiple mechanisms.

    “But other in vitro studies revealed that oligomeric α-synuclein induced mitochondrial dysfunction and neuronal death through multiple mechanisms.56,57”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [57]

    The Results sections on α-synuclein import and downstream consequences report that oligomeric α-synuclein impaired mitochondrial protein import in vitro, reduced respiration, and caused oxidative damage and mitochondrial depolarization. The Discussion describes these as consequences of protein-import impairment but says its contribution to overall neurotoxicity remains undetermined. The paper does not establish neuronal death or multiple mechanisms causing it. (LLM, conf=0.87)

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.
