Self-propagation of pathogenic protein aggregates in neurodegenerative diseases

Abstract

For several decades scientists have speculated that the key to understanding age-related neurodegenerative disorders may be found in the unusual biology of the prion diseases. Recently, owing largely to the advent of new disease models, this hypothesis has gained experimental momentum. In a remarkable variety of diseases, specific proteins have been found to misfold and aggregate into seeds that structurally corrupt like proteins, causing them to aggregate and form pathogenic assemblies ranging from small oligomers to large masses of amyloid. Proteinaceous seeds can therefore serve as self-propagating agents for the instigation and progression of disease. Alzheimer's disease and other cerebral proteopathies seem to arise from the de novo misfolding and sustained corruption of endogenous proteins, whereas prion diseases can also be infectious in origin. However, the outcome in all cases is the functional compromise of the nervous system, because the aggregated proteins gain a toxic function and/or lose their normal function. As a unifying pathogenic principle, the prion paradigm suggests broadly relevant therapeutic directions for a large class of currently intractable diseases.

  • Specific misfolded and aggregated proteins can propagate and spread in a prion-like fashion.

    “The recent discovery that specific misfolded and aggregated proteins can propagate and spread in a prion-like fashion has sparked considerable interest (67).”

  • 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.

  • There is substantial evidence that propagation of pathological tau species occurs between cells.

    “While still a contentious topic [46], there is now substantial evidence that also supports the idea that propagation of pathological tau species occurs between cells [47–50].”

  • Neuropathological lesions of AD, PD/DLB, and ALS are known to spread through the brain in a rather specific pattern, which serves as a basis for neuropathological staging of disease severity.

    “As aforementioned, the neuropathological lesions of not only AD but also PD/DLB and amyotrophic lateral sclerosis (ALS) are known to spread through the brain in a rather specific pattern, which also serves as a basis for the neuropathological staging of disease severity [203].”

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.
