Microglial immune checkpoint mechanisms

Deczkowska, Aleksandra, Amit, Ido, Schwartz, Michal·2018·Nature Neuroscience

Abstract

Microglia differentiate from progenitors that infiltrate the nascent CNS during early embryonic development. They then remain in this unique immune-privileged environment throughout life. Multiple immune mechanisms, which we collectively refer to as microglial checkpoints, ensure efficient and tightly regulated microglial responses to perturbations in the CNS milieu. Such mechanisms are essential for proper CNS development and optimal physiological function. However, in chronic disease or aging, when a robust immune response is required, such checkpoint mechanisms may limit the ability of microglia to protect the CNS. Here we survey microglial checkpoint mechanisms and their roles in controlling microglial function throughout life and in disease, and discuss how they may be targeted therapeutically.

Statistics

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

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?

  • PLCγ2 is present in circulating monocytes, platelets and B-cells, amongst other immune cells.

    “PLCγ2 is present in circulating monocytes, platelets and B-cells, amongst other immune cells (see sections above, [3, 130])”
  • A core function of microglia is the efficient recognition and phagocytic clearance of protein aggregates and cellular debris without damaging surrounding tissue to maintain CNS homeostasis.

  • Microglial phagocytic activity becomes dysfunctional during aging and neurodegenerative diseases, resulting in the gradual accumulation of toxic compounds and cognitive decline.

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.
