Abstract

Oligodendrocyte pathology is increasingly implicated in neurodegenerative diseases as oligodendrocytes both myelinate and provide metabolic support to axons. In multiple sclerosis (MS), demyelination in the central nervous system thus leads to neurodegeneration, but the severity of MS between patients is very variable. Disability does not correlate well with the extent of demyelination 1, which suggests that other factors contribute to this variability. One such factor may be oligodendrocyte heterogeneity. Not all oligodendrocytes are the same-those from the mouse spinal cord inherently produce longer myelin sheaths than those from the cortex 2, and single-cell analysis of the mouse central nervous system identified further differences 3,4. However, the extent of human oligodendrocyte heterogeneity and its possible contribution to MS pathology remain unknown. Here we performed single-nucleus RNA sequencing from white matter areas of post-mortem human brain from patients with MS and from unaffected controls. We identified subclusters of oligodendroglia in control human white matter, some with similarities to mouse, and defined new markers for these cell states. Notably, some subclusters were underrepresented in MS tissue, whereas others were more prevalent. These differences in mature oligodendrocyte subclusters may indicate different functional states of oligodendrocytes in MS lesions. We found similar changes in normal-appearing white matter, showing that MS is a more diffuse disease than its focal demyelination suggests. Our findings of an altered oligodendroglial heterogeneity in MS may be important for understanding disease progression and developing therapeutic approaches.

  • Post-mortem oligodendrocytes had low but detectable APOE expression.

    “Post-mortem oligodendrocytes had low but detectable APOE expression, consistent with previous single-cell resolution reports25 (Extended Data Fig. 5k, l).”

    From APOE4 impairs myelination via cholesterol dysregulation in oligodendrocytes (2022) · cites this paper as [25]

    The Methods (Human Donor tissue; page not given) identify the samples as post-mortem tissue, and the paper identifies APOE as an RNA marker of an oligodendroglial subcluster. It supports detectable APOE expression in that subcluster, but does not establish that expression was low across post-mortem oligodendrocytes generally. (LLM, conf=0.83)

  • These prioritized genes were differentially expressed in MS brain lesion types relative to control white matter.

    “These prioritized genes were differentially expressed in MS brain lesion types relative to control white matter26,27 (Supplementary Note, Supplementary Fig. 6).”

    From Locus for severity implicates CNS resilience in progression of multiple sclerosis (2023) · cites this paper as [26]

    The Methods section, ‘Differential expression analysis between MS Lesions and Control’ (page unavailable), describes a differential-expression analysis of oligodendrocyte-lineage cells. The passage comparing lesion types with control white matter (page unavailable) reports expression differences for several named genes. Our copy does not establish that those genes are the citing document’s ‘prioritized genes,’ so it supports the general finding but not that specific identification. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • Cell expression of ZNF638 was proportionally enriched in control brain tissue and chronic inactive MS lesions compared to other MS lesions.

    “Moreover, cell expression of ZNF638 was proportionally enriched in control brain tissue and chronic inactive MS lesions compared to other MS lesions26.”

    From Locus for severity implicates CNS resilience in progression of multiple sclerosis (2023) · cites this paper as [26]

    The passage discussing lesion markers reports that the proportion of cells expressing several genes was enriched in control white matter and chronic inactive lesions, but not other lesions. It does not name ZNF638 among those genes, and a search for ZNF638 found no supporting passage in our copy. (LLM, conf=0.78)

    Experimental — accuracy not yet measured
  • In single-nucleus RNA sequencing from brain white matter areas in MS patients and controls, ZNF638 was preferentially expressed in an oligodendrocyte cluster with a predicted actively myelinating phenotype.

    “In single-nucleus RNA sequencing from brain white matter areas in MS patients and controls, ZNF638 was preferentially expressed in an oligodendrocyte cluster with a predicted actively myelinating phenotype26.”

    From Locus for severity implicates CNS resilience in progression of multiple sclerosis (2023) · cites this paper as [26]

    The paper reports single-nucleus RNA sequencing of white matter from controls and people with MS (Abstract; page unavailable). It also describes Oligo3 and Oligo4 as clusters predicted by gene-ontology analysis to be actively myelinating (Abstract; page unavailable). Our copy does not identify ZNF638 as preferentially expressed in either cluster, so the gene-specific finding is not supported. (LLM, conf=0.84)

    Experimental — accuracy not yet measured
  • PIGC is expressed in neuronal and glial cells including oligodendrocyte lineage cells in brain white matter tissue.

    “Single nuclear RNA expression from 4 progressive MS patients and 5 non-neurological controls26 confirms PIGC expression in neuronal and glial cells including oligodendrocyte lineage cells.”

    From Locus for severity implicates CNS resilience in progression of multiple sclerosis (2023) · cites this paper as [26]

    The paper reports single-nucleus RNA sequencing of white matter from four people with progressive MS and five non-neurological controls (Abstract; page unavailable). It identifies neuronal and glial cell clusters, including oligodendrocyte-lineage cells, but our copy does not report PIGC expression in those cells (searched: “PIGC” and a cell-type expression paraphrase). (LLM, conf=0.84)

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.
