Reactive microgliosis

Streit, Wolfgang J., Walter, Sharon A., Pennell, Nathan A.·1999·Progress in Neurobiology

Abstract

Damage to the central nervous system (CNS) elicits the activation of both astrocytes and microglia. This review is focused on the principal features that characterize the activation of microglia after CNS injury. It provides a critical discussion of concepts regarding microglial biology that include the relationship between microglia and macrophages, as well as the role of microglia as immunocompetent cells of the CNS. Mechanistic and functional aspects of microgliosis are discussed primarily in the context of microglial neuronal interactions. The controversial issue of whether reactive microgliosis is a beneficial or a harmful process is addressed, and a resolution of this dilemma is offered by suggesting different interpretations of the term 'activated microglia' depending on its usage during in vivo or in vitro experimentation.

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?

  • In response to inflammatory insult, microglia undergo morphological alterations, marked by shorter, thicker processes and enhanced expression of inflammatory markers.

    “In response to inflammatory insult, these cells undergo morphological alterations, marked by shorter, thicker processes and enhanced expression of inflammatory markers (Streit et al, 1999).”

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.
