Astrocytes and microglia: In sickness and in health
Open accessAbstract
Healthy central nervous system (CNS) development and function require an intricate and balanced bidirectional communication between neurons and glia cells. In this review, we discuss the complementary roles of astrocytes and microglia in building the brain, including in the formation and refinement of synapses. We discuss recent evidence demonstrating how these interactions are coordinated in the transition from healthy physiology towards disease and discuss known and potential molecular mechanisms that mediate this cellular crosstalk.

Microglia and astrocytes do not initiate inflammatory responses independently.
“Microglia and astrocytes do not initiate inflammatory responses independently [407].”
From Revisiting the Pathogenesis of X-Linked Adrenoleukodystrophy (2025) · cites this paper as [407]
In “The bond between astrocytes and microglia” (page unavailable), the review says the cells seem to respond almost as one unit when the brain is perturbed. “Cytokine and growth factors in injury and inflammation” describes microglial cytokines inducing a reactive astrocyte phenotype. These passages support coordination, but not the categorical claim that neither cell type initiates inflammatory responses independently. (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.
