Abstract

Microglia are strongly implicated in the development and progression of Alzheimer's disease (AD), yet their impact on pathology and lifespan remains unclear. Here we utilize a CSF1R hypomorphic mouse to generate a model of AD that genetically lacks microglia. The resulting microglial-deficient mice exhibit a profound shift from parenchymal amyloid plaques to cerebral amyloid angiopathy (CAA), which is accompanied by numerous transcriptional changes, greatly increased brain calcification and hemorrhages, and premature lethality. Remarkably, a single injection of wild-type microglia into adult mice repopulates the microglial niche and prevents each of these pathological changes. Taken together, these results indicate the protective functions of microglia in reducing CAA, blood-brain barrier dysfunction, and brain calcification. To further understand the clinical implications of these findings, human AD tissue and iPSC-microglia were examined, providing evidence that microglia phagocytose calcium crystals, and this process is impaired by loss of the AD risk gene, TREM2.

  • Microglial replacement or reprogramming may represent a therapeutic strategy for neurodegenerative and neuroinflammatory disease.

    “Several studies have demonstrated that microglial replacement or reprogramming may represent a therapeutic strategy for neurodegenerative and neuroinflammatory disease.”

    From Older adult APOE4 mice exhibit modest immunometabolic adaptation following microglial APOE2 replacement (2027) · cites this paper as Kiani Shabestari et al., 2022

    The Results (page unavailable) show that transplanted microglia engrafted in Alzheimer’s disease mice and reversed several disease-associated pathologies, supporting the potential of microglial replacement in that model. The paper does not establish reprogramming as a therapeutic strategy or test replacement across neurodegenerative and neuroinflammatory diseases more broadly. (LLM, conf=0.84)

  • Comparison of spatial gene modules with cluster marker genes from a whole-mouse-brain snRNA-seq dataset found significant correspondences, such as the striatum module SM7 and medium spiny neurons (Fisher's exact test FDR <0.05).

    “We compared these gene modules with cluster marker genes from a whole-mouse-brain snRNA-seq dataset28 and found significant correspondences, such as the striatum module SM7 and medium spiny neurons (Fisher’s exact test false discovery rate [FDR] <0.05; Figure S7D).”
  • In another study, the authors showed that scWGCNA was suitable for network analysis using scRNA-seq alone.

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.
