Abstract

One of the characteristics of the central nervous system is the lack of a classical lymphatic drainage system. Although it is now accepted that the central nervous system undergoes constant immune surveillance that takes place within the meningeal compartment, the mechanisms governing the entrance and exit of immune cells from the central nervous system remain poorly understood. In searching for T-cell gateways into and out of the meninges, we discovered functional lymphatic vessels lining the dural sinuses. These structures express all of the molecular hallmarks of lymphatic endothelial cells, are able to carry both fluid and immune cells from the cerebrospinal fluid, and are connected to the deep cervical lymph nodes. The unique location of these vessels may have impeded their discovery to date, thereby contributing to the long-held concept of the absence of lymphatic vasculature in the central nervous system. The discovery of the central nervous system lymphatic system may call for a reassessment of basic assumptions in neuroimmunology and sheds new light on the aetiology of neuroinflammatory and neurodegenerative diseases associated with immune system dysfunction.

  • Lymphatic vessels draining from CSF to neck lymph nodes were first detected in walls of dural venous sinuses in 2015.

    “In 2015, lymphatic vessels draining from CSF to neck lymph nodes were for the first time detected in walls of dural venous sinuses (51, 52).”
  • Meningeal lymphatic vessels in the dura drain brain interstitial CSF.

    “two other groups reported that classical lymphatic vessels draining brain interstitial CSF might also be identified in the dura – the fibrous external layer of the meningeal membranes (39, 40).”

  • The glymphatic and meningeal lymphatic systems are connected, and CSF tracers exit the CNS via meningeal lymphatic vessels, especially ventral lymph vessels draining to cervical lymph nodes.

    “Yet the glymphatic and meningeal lymphatic systems are clearly connected: CSF tracers can exit the CNS via the meningeal lymphatic vessels, particularly by way of the lymph vessels draining the ventral aspect of the brain draining to the cervical lymph nodes (39, 40, 42).”

  • Louveau et al showed active lymphatic vessels connecting the CNS to the lymphatic system that may act as a conduit for neuroimmunological dysfunction.

    “the recent groundbreaking work by Louveau et al (2015) showing active lymphatic vessels connecting the CNS to the lymphatic system that may possibly act as a conduit for neuroimmunological dysfunction.”

  • Initial lymphatics at the dorsal brain meninges are important for cerebrospinal fluid drainage.

    “These results emphasize the importance of initial lymphatics at the dorsal brain meninges in CSF drainage5,12,18.”

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.
