Cross talk between activation of microglia and astrocytes in pathological conditions in the central nervous system

Liu, W., Tang, Y., Feng, J.·2011·Life Sciences

Abstract

Microglia and astrocytes in the central nervous system are now recognized as active participants in various pathological conditions such as trauma, stroke, or chronic neurodegenerative disorders. Their activation is closely related with the development and severity of diseases. Interestingly, activation of microglia and astrocytes occurs with a spatially and temporarily distinct pattern. The present review explores the cross talk in the process of their activation. Microglia, activated earlier than astrocytes, promote astrocytic activation. On the other hand, activated astrocytes not only facilitate activation of distant microglia, but also inhibit microglial activities. Molecules contributing to their intercommunication include interleukin-1 (IL-1), adenosine triphosphate (ATP), and transforming growth factor beta (TGF-β). A better understanding about the cross talk between activation of microglia and astrocytes would be helpful to elucidate the role of glial cells in pathological conditions, which could accelerate the development of treatment for various diseases.

Claims other papers make about this one

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

  • Activated astrocytes release ATP that can activate purinergic receptors on neighboring microglia, resulting in microglial activation.

    “Previous research has shown that activated astrocytes release adenosine triphosphate (ATP) that can activate the purinergic receptors on neighboring microglia, resulting in microglial activation (Figure 3A) (Davalos et al., 2005;Liu et al., 2011;Schipke et al., 2002;Verderio and Matteoli, 2001).”
  • Activated astrocytes release ATP which activates the purinergic receptors on microglia, resulting in microglial activation.

    “As mentioned earlier, activated astrocytes release ATP which activates the purinergic receptors on microglia, resulting in microglial activation (Figure 3A) (Davalos et al., 2005;Liu et al., 2011;Schipke et al., 2002;Verderio and Matteoli, 2001).”

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.
