Abstract

Altered proteome profiles have been reported in both postmortem brain tissues and body fluids of subjects with Alzheimer disease (AD), but their broad relationships with AD pathology, amyloid pathology, and tau-related neurodegeneration have not yet been fully explored. Using a robust automated MS-based proteomic biomarker discovery workflow, we measured cerebrospinal fluid (CSF) proteomes to explore their association with well-established markers of core AD pathology. Cross-sectional analysis was performed on CSF collected from 120 older community-dwelling adults with normal ( n = 48) or impaired cognition ( n = 72). LC-MS quantified hundreds of proteins in the CSF. CSF concentrations of β-amyloid 1–42 (Aβ 1–42 ), tau, and tau phosphorylated at threonine 181 (P-tau181) were determined with immunoassays. First, we explored proteins relevant to biomarker-defined AD. Then, correlation analysis of CSF proteins with CSF markers of amyloid pathology, neuronal injury, and tau hyperphosphorylation (i.e., Aβ 1–42 , tau, P-tau181) was performed using Pearson’s correlation coefficient and Bonferroni correction for multiple comparisons. We quantified 790 proteins in CSF samples with MS. Four CSF proteins showed an association with CSF Aβ 1–42 levels ( p value ≤ 0.05 with correlation coefficient ( R ) ≥ 0.38). We identified 50 additional CSF proteins associated with CSF tau and 46 proteins associated with CSF P-tau181 ( p value ≤ 0.05 with R ≥ 0.37). The majority of those proteins that showed such associations were brain-enriched proteins. Gene Ontology annotation revealed an enrichment for synaptic proteins and proteins originating from reelin-producing cells and the myelin sheath. We used an MS-based proteomic workflow to profile the CSF proteome in relation to cerebral AD pathology. We report strong evidence of previously reported CSF proteins and several novel CSF proteins specifically associated with amyloid pathology or neuronal injury and tau hyperphosphorylation.

  • Four proteins (GPNMB, SMOC1, NPTX2, VGF) were previously reported in AD CSF.

    “In the list, 4 proteins (GPNMB, SMOC1, NPTX2 and VGF) have previously been reported in AD CSF (Dayon et al., 2018; Huttenrauch et al., 2018; Llano et al., 2019; Xiao et al., 2017)”

    From Deep Multilayer Brain Proteomics Identifies Molecular Networks in Alzheimer’s Disease Progression (2020) · cites this paper as Dayon et al., 2018

    The Results and Discussion report NPTX2 and SMOC1 as CSF proteins associated with biomarkers of Alzheimer pathology. Our copy does not report GPNMB or VGF, so it supports only two of the four proteins attributed to this citation. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • SMOC1 and GPNMB were reported to be CSF biomarker candidates for Alzheimer's disease in other recent biomarker studies.

    “Consistently, SMOC1 and GPNMB were reported to be CSF biomarker candidates for AD in other recent biomarker studies [62, 69].”

    From Integrated analysis of ultra-deep proteomes in cortex, cerebrospinal fluid and serum reveals a mitochondrial signature in Alzheimer’s disease (2020) · cites this paper as [69]

    The Results section (page not available) identifies SMOC1 among CSF proteins that differed significantly between AD biomarker-profile groups, supporting its description as a candidate biomarker. The passages from our copy do not identify GPNMB as a CSF biomarker candidate; a search for GPNMB and its expanded name found no matching passage. (LLM, conf=0.88)

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.
