Microglia Function in Central Nervous System Development and Plasticity

Open access
Schafer, Dorothy P., Stevens, Beth·2015·Cold Spring Harbor Perspectives in Biology

Abstract

The nervous system comprises a remarkably diverse and complex network of different cell types, which must communicate with one another with speed, reliability, and precision. Thus, the developmental patterning and maintenance of these cell populations and their connections with one another pose a rather formidable task. Emerging data implicate microglia, the resident myeloid-derived cells of the central nervous system (CNS), in the spatial patterning and synaptic wiring throughout the healthy, developing, and adult CNS. Importantly, new tools to specifically manipulate microglia function have revealed that these cellular functions translate, on a systems level, to effects on overall behavior. In this review, we give a historical perspective of work to identify microglia function in the healthy CNS and highlight exciting new work in the field that has identified roles for these cells in CNS development, maintenance, and plasticity.

  • Microglia are macrophage-like cells that comprise 10-15% of the CNS and mediate diverse functions ranging from innate immunity and phagocytosis to synaptic pruning and the regulation of synaptic activity.

    “Microglia are macrophage-like cells that comprise 10–15% of the CNS, and mediate diverse functions ranging from innate immunity and phagocytosis to synaptic pruning and the regulation of synaptic activity [416,417].”
  • Activation of microglia through genetic, infectious, inflammatory, or physical stimuli leads to stereotypical changes in their morphology, accompanied by proliferation, migration, and the release of proinflammatory cytokines and chemokines.

    “Activation of microglia through genetic, infectious, inflammatory, or physical stimuli, leads to stereotypical changes in their morphology, accompanied by proliferation, migration, and the release of proinflammatory cytokines and chemokines [417–419].”
  • Microglia are the resident macrophage population of the central nervous system that perform functions required for typical development, homeostasis, plasticity, immunity and repair.

    “Microglia are the resident macrophage population of the central nervous system (CNS) that perform functions required for typical development, as well as homeostasis, plasticity, immunity and repair (1–5).”

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.
