Immune Surveillance of the CNS following Infection and Injury

Abstract

The central nervous system (CNS) contains a sophisticated neural network that must be constantly surveyed in order to detect and mitigate a diverse array of challenges. The innate and adaptive immune systems actively participate in this surveillance, which is critical for the maintenance of CNS homeostasis and can facilitate the resolution of infections, degeneration, and tissue damage. Infections and sterile injuries represent two common challenges imposed on the CNS that require a prompt immune response. While the inducers of these two challenges differ in origin, the resultant responses orchestrated by the CNS share some overlapping features. Here, we review how the CNS immunologically discriminates between pathogens and sterile injuries, mobilizes an immune reaction, and, ultimately, regulates local and peripherally-derived immune cells to provide a supportive milieu for tissue repair.

  • In AD and CNS infections, pro- and anti-inflammatory signaling is primarily initiated by CNS resident immune cells, the astrocytes, and microglia.

    “In AD and CNS infections, pro- and anti-inflammatory signaling is primarily initiated by CNS resident immune cells, the astrocytes, and microglia (Di Benedetto et al., 2022; Russo and McGavern, 2015).”

    From Arbovirus infection increases the risk for the development of neurodegenerative disease pathology in the murine model (2024) · cites this paper as Russo and McGavern, 2015

    The sections on pathogen recognition and regulation of neuroinflammation describe microglial inflammatory responses to CNS infection and say that microglia and astrocytes can secrete anti-inflammatory cytokines. The paper does not establish that these cells primarily initiate both kinds of signaling. Its only discussion of Alzheimer’s disease, in “Immune clean-up of the injured CNS,” concerns microglial uptake of β-amyloid, not initiation of inflammatory signaling in AD. (LLM, conf=0.86)

  • Sterile injuries involve release of alarmins detected by damage-associated molecular pattern (DAMP) sensors such as Toll-like and purinergic receptors.

    “A great deal is known about sterile injuries; they involve release of alarmins detected by damage-associated molecular pattern (DAMP) sensors such as Toll-like and purinergic receptors (131).”

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.
