Abstract

About two thirds of the patients affected with lysosomal storage diseases (LSD) experience neurological manifestations, such as developmental delay, seizures, or psychiatric problems. In order to develop efficient therapies, it is crucial to understand the neuropathophysiology underlying these symptoms. How exactly lysosomal storage affects biogenesis and function of neurons is still under investigation however recent research highlights a substantial role played by synaptic defects, such as alterations in synaptic spines, synaptic proteins, postsynaptic densities, and synaptic vesicles that might lead to functional impairments in synaptic transmission and neurodegeneration, finally culminating in massive neuronal death and manifestation of cognitive symptoms. Unveiling how the synaptic components are affected in neurological LSD will thus enable a better understanding of the complexity of disease progression as well as identify crucial targets of therapeutic relevance and optimal time windows for targeted intervention.

  • Cathepsin D knockout mice accumulate Ab in addition to lipofuscin.

    “As an example, cathepsin D knockout mice accumulate Ab in addition to lipofuscin, and Alzheimer’s pathology has been observed in postmortem tissues from several NCL patients.125–127”

    From The lysosome and proteostatic stress at the intersection of pediatric neurological disorders and adult neurodegenerative diseases (2025) · cites this paper as [125]

    Section 3 links cathepsin D deficiency to NCL10 but discusses synaptic vesicle recycling, not deposits in knockout mice. The Introduction mentions amyloid-β in multiple lysosomal storage diseases, and Section 4 describes storage material in CLN5 patient-derived cells; neither establishes that cathepsin D knockout mice accumulate amyloid-β and lipofuscin. Searched for cathepsin D knockout, amyloid-β, and lipofuscin. (LLM, conf=0.76)

  • Alzheimer's pathology has been observed in postmortem tissues from several NCL patients.

    “As an example, cathepsin D knockout mice accumulate Ab in addition to lipofuscin, and Alzheimer’s pathology has been observed in postmortem tissues from several NCL patients.125–127”

    From The lysosome and proteostatic stress at the intersection of pediatric neurological disorders and adult neurodegenerative diseases (2025) · cites this paper as [125]

    The Introduction (page unavailable) links amyloid-β and tau to CNS pathology in multiple lysosomal storage diseases, but does not identify postmortem NCL patients. The NCL passages in sections 2 and 4 discuss animal models and patient-derived cells, not Alzheimer’s pathology in postmortem tissue. Searches for postmortem NCL tissue, amyloid, and Alzheimer’s pathology found no passage establishing the claim. (LLM, conf=0.72)

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.
