Abstract

Vesicles shed from astrocytes after brain trauma trigger hepatic cytokine release to mobilize the peripheral immune response.

  • EVs have functional roles in neuron-glia and CNS-periphery communication following neurotrauma by regulating neuronal function, axonal regeneration and remyelination, metabolic activity, and the inflammatory milieu.

    “EVs have functional roles in neuron–glia and CNS–periphery communication following neurotrauma by regulating neuronal function, axonal regeneration and remyelination, metabolic activity, and the inflammatory milieu [192, 193].”

    From Extracellular vesicles as nanotheranostic platforms for targeted neurological disorder interventions (2024) · cites this paper as [192]

    The Introduction and Discussion report that astrocyte-shed EVs communicate inflammatory brain injury to the peripheral immune system and promote leukocyte recruitment. The paper studies IL-1β–induced inflammatory lesions in mice; it does not establish the claimed roles in neuron–glia communication, neuronal function, axonal regeneration, remyelination, or metabolic activity following neurotrauma.

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.
