Abstract

Ageing is a major risk factor for many neurological pathologies, but its mechanisms remain unclear. Unlike other tissues, the parenchyma of the central nervous system (CNS) lacks lymphatic vasculature and waste products are removed partly through a paravascular route. (Re)discovery and characterization of meningeal lymphatic vessels has prompted an assessment of their role in waste clearance from the CNS. Here we show that meningeal lymphatic vessels drain macromolecules from the CNS (cerebrospinal and interstitial fluids) into the cervical lymph nodes in mice. Impairment of meningeal lymphatic function slows paravascular influx of macromolecules into the brain and efflux of macromolecules from the interstitial fluid, and induces cognitive impairment in mice. Treatment of aged mice with vascular endothelial growth factor C enhances meningeal lymphatic drainage of macromolecules from the cerebrospinal fluid, improving brain perfusion and learning and memory performance. Disruption of meningeal lymphatic vessels in transgenic mouse models of Alzheimer's disease promotes amyloid-β deposition in the meninges, which resembles human meningeal pathology, and aggravates parenchymal amyloid-β accumulation. Meningeal lymphatic dysfunction may be an aggravating factor in Alzheimer's disease pathology and in age-associated cognitive decline. Thus, augmentation of meningeal lymphatic function might be a promising therapeutic target for preventing or delaying age-associated neurological diseases.

  • Aβ deposition observed in brain regions devoid of microglia, including dura mater, choroid plexus, perivascular space.

    “Aβ deposition can also be observed in regions of the brain devoid of microglia, including the dura mater, choroid plexus and perivascular space [71, 253]”

    From Microglia and monocytes in inflammatory CNS disease: integrating phenotype and function (2022) · cites this paper as [71]

    The ‘Dysfunctional lymphatics in amyloid pathology’ section reports Aβ deposition in the dura mater of Alzheimer’s disease patients. It does not establish deposition in the choroid plexus or perivascular space, or state that the listed sites are devoid of microglia; searches for those terms found no supporting passage. No page number is available in our copy. (LLM, conf=0.87)

    Experimental — accuracy not yet measured
  • Microglia may not be only cells contributing to Aβ plaque aggregation.

    “suggesting that microglia may not be the only cells contributing to Aβ plaque aggregation”

    From Microglia and monocytes in inflammatory CNS disease: integrating phenotype and function (2022) · cites this paper as [71]

    In “Dysfunctional lymphatics in amyloid pathology” (page not provided), the paper reports macrophages recruited to Aβ aggregates and increased hippocampal plaque load after meningeal lymphatic ablation. These findings support the suggestion that processes beyond microglia affect amyloid pathology, but they do not establish that macrophages or other cells contribute to plaque aggregation itself. (LLM, conf=0.82)

    Experimental — accuracy not yet measured
  • VEGFC overexpression induced sprouting of meningeal lymphatic vessels and slowed cognitive decline in a mouse model of Alzheimer disease.

    “VEGFC-overexpression induced spouting of the meningeal lymphatic vessels and slowed the cognitive decline in a mouse model of Alzheimer disease (50).”

  • Aging is associated with a steep fall in glymphatic flow in rodent and human brains.

    “Aging is also associated with a steep fall in glymphatic flow in the brains of both rodents and humans.”

  • UV photoablation of meningeal lymphatic vessels and mechanical ligation of cervical lymphatics aggravated amyloid plaque formation in mouse models of Alzheimer disease.

    “Conversely, both UV photoablation of meningeal lymphatic vessels and mechanical ligation of cervical lymphatics aggravated amyloid plaque formation in the same mouse models of Alzheimer disease (50, 51).”

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.
