Prion-like transmission of protein aggregates in neurodegenerative diseases

Abstract

Neurodegenerative diseases are commonly associated with the accumulation of intracellular or extracellular protein aggregates. Recent studies suggest that these aggregates are capable of crossing cellular membranes and can directly contribute to the propagation of neurodegenerative disease pathogenesis. We propose that, once initiated, neuropathological changes might spread in a 'prion-like' manner and that disease progression is associated with the intercellular transfer of pathogenic proteins. The transfer of naked infectious particles between cells could therefore be a target for new disease-modifying therapies.

  • In Parkinson's disease and Lewy body disease, α-synuclein aggregates initially spread through brainstem and olfactory bulb, followed by limbic structures, and only then to neocortex.

    “In Parkinson’s disease and Lewy body disease, α-synuclein aggregates initially spread through the brainstem and olfactory bulb followed by limbic structures, and only thence to the neocortex.”

  • In these neurodegenerative diseases, aggregates initially deposit at the ventral base of the forebrain and midbrain and then extend rostrally and dorsally to the cortex.

  • Recent neuroimaging advances provide approaches to map the human glymphatic system and assess its functional competence in disease and effects on sleep-dependent glymphatic cyclicity.

    “In that regard, recent advances in neuroimaging have provided multiple approaches to map the human glymphatic system, and hence to assess its functional competence in the context of disease, as well as of the effects thereof on sleep-dependent glymphatic cyclicity (72, 73, 108).”

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.
