Abstract

Alzheimer’s disease is a pervasive neurodegenerative disorder, the molecular complexity of which remains poorly understood. Here, we analysed 80,660 single-nucleus transcriptomes from the prefrontal cortex of 48 individuals with varying degrees of Alzheimer’s disease pathology. Across six major brain cell types, we identified transcriptionally distinct subpopulations, including those associated with pathology and characterized by regulators of myelination, inflammation, and neuron survival. The strongest disease-associated changes appeared early in pathological progression and were highly cell-type specific, whereas genes upregulated at late stages were common across cell types and primarily involved in the global stress response. Notably, we found that female cells were overrepresented in disease-associated subpopulations, and that transcriptional responses were substantially different between sexes in several cell types, including oligodendrocytes. Overall, myelination-related processes were recurrently perturbed in multiple cell types, suggesting that myelination has a key role in Alzheimer’s disease pathophysiology. Our single-cell transcriptomic resource provides a blueprint for interrogating the molecular and cellular basis of Alzheimer’s disease. Single-cell transcriptomics from 48 individuals with varying degrees of Alzheimer’s disease pathology demonstrates that gene-expression changes in Alzheimer’s disease are both cell-type specific and shared, and that transcriptional responses show sexual dimorphism.

  • snRNA-seq analyses of human brain samples have failed to detect a consistent microglial activation signature in Alzheimer's disease.

    “snRNA-seq analyses of human brain samples have failed to detect a consistent microglial activation signature in Alzheimer’s disease.”

    From Single-Nucleus RNA-Seq Is Not Suitable for Detection of Microglial Activation Genes in Humans (2020) · cites this paper as Mathys et al., 2019

    In “Identification of AD-associated cellular subpopulations” (page not specified), the paper reports an AD-associated human microglial subpopulation, Mic1, with immune-related marker genes that significantly overlap disease-associated microglial signatures. It also reports immunohistochemical confirmation of MHC class II–expressing microglia in AD-pathology samples. This is contrary to attributing a failure to detect a microglial activation signature to this study, though the paper does not establish consistency across all human snRNA-seq studies. (LLM, conf=0.87)

  • The opposing protective and harmful microglial states are accompanied by broad changes in gene expression, suggesting that defined transcriptional programs in microglia may govern their neuroprotective or neurotoxic functions.

    “These opposing states are accompanied by broad changes in gene expression12–17, suggesting that defined transcriptional programs in microglia may govern their neuroprotective or neurotoxic functions.”

    From Lymphoid gene expression supports neuroprotective microglia function (2025) · cites this paper as [14]

    The section on AD-associated cellular subpopulations identifies a distinct microglial state with AD-associated marker genes, supporting a link between microglial states and changes in gene expression. It does not establish that the states are opposing protective and harmful states; the Discussion says distinguishing neuroprotection from pathogenicity remains future work. The suggestion that transcriptional programs govern those functions is the citing authors’ inference, not a finding established by this source. (LLM, conf=0.84)

  • Microarrays and bulk RNA-Seq are scalable and cost-effective but lack single-cell resolution.

    “Microarrays and bulk RNA-Seq are scalable and cost-effective but lack single-cell resolution.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [118]

    The discussion of differential expression reports that bulk RNA-seq misses changes in some cell types and cannot capture genes changing in opposite directions across cell types, supporting the resolution limitation. Our copy does not establish that microarrays and bulk RNA-seq are scalable or cost-effective, or specifically discuss microarrays in this comparison. No page numbers are available in our copy.

  • Single-cell and single-nucleus methods deliver high granularity but require significant technical and computational resources.

    “Single-cell and single-nucleus methods deliver high granularity but require significant technical and computational resources.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [118]

    The Abstract (page unavailable) supports high granularity: the study profiles individual nuclei and identifies cell-type-specific changes. The Methods describe specialized sequencing equipment and a multistep computational pipeline, but do not establish that these methods generally require significant resources. (LLM, conf=0.82)

  • Epigenetic profiles in glial cells may differ substantially from those in neurons and may play critical roles in processes such as amyloid plaque deposition and neuroinflammation.

    “This level of resolution is essential, as epigenetic profiles in glial cells may differ substantially from those in neurons and may play critical roles in processes such as amyloid plaque deposition and neuroinflammation118.”

    From Artificial intelligence-driven multi-omics approaches in Alzheimer's disease: Progress, challenges, and future directions (2025) · cites this paper as [118]

    The differential-expression analysis (page not available) finds that 95% of altered genes were perturbed only in neurons or in one glial cell type, supporting the need for cell-level resolution. But this study measures transcriptional changes, not differences in epigenetic profiles, and the cited passages do not establish a role for those profiles in amyloid plaque deposition or neuroinflammation.

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.
