Astrocyte regulation of synaptic behavior

Open access
Allen, Nicola J.·2014·Annual Review of Cell and Developmental Biology

Abstract

Astrocytes regulate multiple aspects of neuronal and synaptic function from development through to adulthood. Instead of addressing each function independently, this review provides a comprehensive overview of the different ways astrocytes modulate neuronal synaptic function throughout life, with a particular focus on recent findings in each area. It includes the emerging functions of astrocytes, such as a role in synapse formation, as well as more established roles, including the uptake and recycling of neurotransmitters. This broad approach covers the many ways astrocytes and neurons constantly interact to maintain the correct functioning of the brain. It is important to consider all of these diverse functions of astrocytes when investigating how astrocyte-neuron interactions regulate synaptic behavior to appreciate the complexity of these ongoing interactions.

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

  • In the aging cortex, increased production of Sparc may inhibit synaptic function and block new synapse formation.

    “suggesting that, in the aging cortex, increased production of Sparc may inhibit synaptic function and block new synapse formation (Figure 4B).”
  • Astrocyte functions include recycling neurotransmitters, buffering extracellular potassium to facilitate neuronal transmission, and taking up and processing nutrients for neurons.

    “Functions include recycling neurotransmitters and buffering extracellular potassium to facilitate neuronal transmission (Allen, 2014) and taking up nutrients, including lipids and sugars from the blood, processing them, and delivering them to neurons for energy (van Deijk et al., 2017).”

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.
