Abstract

Despite the established dogma of central nervous system (CNS) immune privilege, neuroimmune interactions play an active role in diverse neurological disorders. However, the precise mechanisms underlying CNS immune surveillance remain elusive; particularly, the anatomical sites where peripheral adaptive immunity can sample CNS-derived antigens and the cellular and molecular mediators orchestrating this surveillance. Here, we demonstrate that CNS-derived antigens in the cerebrospinal fluid (CSF) accumulate around the dural sinuses, are captured by local antigen-presenting cells, and are presented to patrolling T cells. This surveillance is enabled by endothelial and mural cells forming the sinus stromal niche. T cell recognition of CSF-derived antigens at this site promoted tissue resident phenotypes and effector functions within the dural meninges. These findings highlight the critical role of dural sinuses as a neuroimmune interface, where brain antigens are surveyed under steady-state conditions, and shed light on age-related dysfunction and neuroinflammatory attack in animal models of multiple sclerosis.

  • The dura mater is the epicenter of immune surveillance in the brain, where macrophages present antigens to T cells to induce immune responses.

    “The dura mater is considered the epicenter of immune surveillance in the brain, where macrophages present antigens to T cells to induce immune responses (66).”
  • During aging, the meninges undergo a shift towards pro-inflammatory immune responses, characterized by an increased number of T cells and B cells.

    “During aging, the meninges undergo a shift towards pro-inflammatory immune responses, characterized by an increased number of T cells and B cells.”
  • In 13-14-month-old 5xFAD mice, dorsal meningeal lymphatic deterioration coincides with a significant rise in amyloid-beta deposition throughout the meninges, including along blood and lymphatic vessels.

    “The deterioration of the lymphatic vasculature at the dorsal meninges observed in 13–14-month-old 5xFAD mice was accompanied by a significant increase in Aβ deposition throughout the meninges (Extended Data Fig. 1c–e), with extensive Aβ deposition along the blood and lymphatic vasculature (Extended Data Fig. 1a, insets) at anatomical locations previously shown as ‘hot spots’ along meningeal lymph”

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.
