Neurotoxic reactive astrocytes are induced by activated microglia

Open access

Abstract

Reactive astrocytes are strongly induced by central nervous system (CNS) injury and disease, but their role is poorly understood. Here we show that a subtype of reactive astrocytes, which we termed A1, is induced by classically activated neuroinflammatory microglia. We show that activated microglia induce A1 astrocytes by secreting Il-1α, TNF and C1q, and that these cytokines together are necessary and sufficient to induce A1 astrocytes. A1 astrocytes lose the ability to promote neuronal survival, outgrowth, synaptogenesis and phagocytosis, and induce the death of neurons and oligodendrocytes. Death of axotomized CNS neurons in vivo is prevented when the formation of A1 astrocytes is blocked. Finally, we show that A1 astrocytes are abundant in various human neurodegenerative diseases including Alzheimer's, Huntington's and Parkinson's disease, amyotrophic lateral sclerosis and multiple sclerosis. Taken together these findings help to explain why CNS neurons die after axotomy, strongly suggest that A1 astrocytes contribute to the death of neurons and oligodendrocytes in neurodegenerative disorders, and provide opportunities for the development of new treatments for these diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • C3 marker evidence cites the OPC figure

    Minor

    The cited Extended Data Figure 10 addresses OPC proliferation and differentiation. The caption reporting that A2-cassette-expressing cells were not C3-positive is Extended Data Figure 12.

  • LGN experiment cites the synapse-formation figure

    Minor

    The cited Extended Data Figure 6 is captioned as a synapse-formation and neurite-outgrowth experiment. The legend describing LGN astrocytes after LPS injection is numbered Figure 7.

  • Motor-neuron subtype result cites the LGN figure

    Minor

    The motor-neuron subtype analysis is identified as panel m of Extended Data Figure 8, not Figure 7; the Figure 7 caption concerns LGN astrocytes.

  • LPS response in cultured astrocytes points to an unrelated extended-data figure

    Minor

    The cited Extended Data Figure 2 concerns microglia depletion in PLX-3397-treated mice, not the response of cultured astrocytes to LPS.

  • Synapse assay cites the astrocyte-morphology figure

    Minor

    The RGC synapse assay cites Extended Data Figure 5, whose caption concerns astrocyte morphology. Synapse formation is the subject of Extended Data Figure 6.

  • Knockout microglial-response citation points to a different experiment

    Minor

    The text cites Extended Data Figure 4 for microglial activation in knockout mice, but that experiment is captioned Extended Data Figure 11. Figure 4 instead describes astrocyte treatments with candidate mediators.

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.

A language model drew the claims from the paper on 2026-10-18, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).

A second model labelled each claim on 2026-10-18 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).

Cited sources are checked with a language model’s help (gpt-6-sol).

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.
