Emerging roles of astrocytes in neural circuit development

Open access
Clarke, Laura E., Barres, Ben A.·2013·Nature Reviews Neuroscience

Abstract

Astrocytes are now emerging as key participants in many aspects of brain development, function and disease. In particular, new evidence shows that astrocytes powerfully control the formation, maturation, function and elimination of synapses through various secreted and contact-mediated signals. Astrocytes are also increasingly being implicated in the pathophysiology of many psychiatric and neurological disorders that result from synaptic defects. A better understanding of how astrocytes regulate neural circuit development and function in the healthy and diseased brain might lead to the development of therapeutic agents to treat these diseases.

  • Astrocytes support neurite outgrowth, neuronal survival, synapse formation and synaptic pruning, all vital during brain development.

    “As the most numerous cell type in the mammalian brain, astrocytes support neurite outgrowth, neuronal survival, synapse formation and synaptic pruning, all of which are vital during brain development (Chung et al., 2013; Clarke and Barres, 2013).”

    From Sterol dysregulation in Smith–Lemli–Opitz syndrome causes astrocyte immune reactivity through microglia crosstalk (2022) · cites this paper as Clarke and Barres, 2013

    The Conclusions and future perspectives section says astrocytes control synapse formation and elimination, and the Astrocyte control of synapse pruning section places elimination during brain development. The passages found do not establish that astrocytes are the most numerous mammalian brain cell type or directly support the attributed roles in neurite outgrowth and neuronal survival; those terms appear chiefly in reference titles.

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.
