Abstract

Individual reports suggest that the central nervous system (CNS) contains multiple immune cell types with diverse roles in tissue homeostasis, immune defense, and neurological diseases. It has been challenging to map leukocytes across the entire brain, and in particular in pathology, where phenotypic changes and influx of blood-derived cells prevent a clear distinction between reactive leukocyte populations. Here, we applied high-dimensional single-cell mass and fluorescence cytometry, in parallel with genetic fate mapping systems, to identify, locate, and characterize multiple distinct immune populations within the mammalian CNS. Using this approach, we revealed that microglia, several subsets of border-associated macrophages and dendritic cells coexist in the CNS at steady state and exhibit disease-specific transformations in the immune microenvironment during aging and in models of Alzheimer's disease and multiple sclerosis. Together, these data and the described framework provide a resource for the study of disease mechanisms, potential biomarkers, and therapeutic targets in CNS disease.

  • Inflammatory cytokines have been seen previously in a sub-set of microglia in aged C57BL/6 mice.

    “inflammatory cytokines have been seen previously in a sub-set of microglia in aged C57BL/6 mice”

    From Cross-Species Single-Cell Analysis Reveals Divergence of the Primate Microglia Program (2019) · cites this paper as Mrdjen et al., 2018

    The Aging and Neurodegenerative Disease section describes a reactive subset of microglia in geriatric mice, and Figure 5 (p. 389) identifies the mice as C57BL/6. The reported features are surface and activation markers, not inflammatory cytokines detected in those microglia. The Discussion mentions cytokines as possible environmental cues, which does not establish the claimed observation. (LLM, conf=0.88)

  • CAMs clear harmful substances through phagocytosis, antigen presentation, and cytokine production.

    “As immune surveillants, CAMs clear harmful substances through phagocytosis, antigen presentation, and cytokine production [364,368,371,372,373,374,375,376]”

    From Revisiting the Pathogenesis of X-Linked Adrenoleukodystrophy (2025) · cites this paper as [368]

    The BAM-subsets section (p. 384–385) identifies CNS border-associated macrophages with MHCII expression, a marker relevant to antigen presentation. But the paper does not show BAMs clearing harmful substances by antigen presentation, phagocytosis, or cytokine production; its Discussion describes their functions as subjects for future study. The phagocytosis passage in the Discussion (p. 391) concerns infiltrating monocyte-derived cells, not BAMs. (LLM, conf=0.77)

    Experimental — accuracy not yet measured
  • BAMs display regional heterogeneity and can be classified into multiple subtypes with diverse signatures.

    “However, recent studies using high-dimensional single-cell analysis revealed that BAMs display regional heterogeneity and can be classified into multiple subtypes with diverse signatures.515,516”

    From Role of neuroinflammation in neurodegeneration development (2023) · cites this paper as [515]

  • The existence of DAM in mice and humans has recently been confirmed in tauopathy AD models, aging, and other neurodegenerative diseases such as ALS and multiple sclerosis.

    “The existence of DAM in mice and humans has recently been confirmed in tauopathy AD models (26, 27), aging (27, 28), and other neurodegenerative diseases, such as amyotrophic lateral sclerosis (ALS) (29) and multiple sclerosis (30).”
  • Perivascular macrophages belong to CNS border-associated macrophages (CAMs).

    “They belong to CNS border-associated macrophages (CAMs) [367,368].”

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.
