APOE4 expression causes distinct effects on meningeal immunity, brain lipid composition, and cognition in male and female mice

ABSTRACT: This experiment was designed to understand the distinct effects of sex and APOE genotype on the transcriptome of meningeal dural vascular and resident immune cells. After transcardiac perfusion with a buffered saline solution containing heparin and actinomycin D, meningeal dural whole mounts were immediately dissected from the skulls of 12-month-old male and female mice expressing APOE3 or APOE4 and digested into a single-cell suspension. After enrichment for CD31+ cells via positive selection using MACS, the cells were counted and approximately 5000 cells per sample were used to obtain single-cell gene expression libraries using 10x Genomics equipment and reagents, namely the Chromium Single Cell 3' Reagent Kits. The generated libraries were sequenced in 2 lanes of a NovaSeq 6000 S4 PE100 flow cell.

Project description:The meningeal lymphatic network—housed within the dural meninges surrounding the brain— is critical for cerebrospinal fluid (CSF) drainage. Through continuous brain interstitial fluid (ISF) mixing with CSF via the glymphatic system, this lymphatic network facilitates the removal of central nervous system (CNS) waste. During aging and in Alzheimer’s disease (AD), attenuated meningeal lymphatic drainage promotes the buildup of toxic misfolded proteins—including amyloid beta—in the CNS. Alleviating this age-related meningeal lymphatic dysfunction represents a promising therapeutic strategy to alleviate AD pathology. However, the mechanisms underlying this lymphatic decline remain elusive. Here we demonstrate that age-related alterations in meningeal immunity contribute to meningeal lymphatic impairment. Single-cell RNA-sequencing of dural lymphatic endothelial cells in aged mice demonstrated a response signature to the cytokine IFNγ, which was elevated in the aged dura due to meningeal T cell accumulation. Chronic elevation of IFNγ in the meninges of young mice via AAV-mediated overexpression altered lymphatic adherans junctions and impaired CSF drainage to deep cervical lymph nodes—comparable to the deficits observed in aged mice. Direct disruption of lymphatic junctions via CSF-delivered VE-Cadherin disrupting antibodies was sufficient to phenocopy impairments in CSF drainage. Therapeutically, IFNγ neutralization in aged mice alleviated age-related impairments in meningeal lymphatic function. These data suggest manipulation of meningeal immunity as a viable therapeutic target to normalize CSF drainage in aged mice and alleviate the pathology in AD mice associated with impaired waste removal.

Gene expression profile at single cell level of immune cells from the dura mater of naïve C57BL6/N mice and during different phases of EAE.

Project description:While macrophages in the meningeal compartments of the central nervous system (CNS) has been comprehensively characterized under steady state, studying their contribution to physiological and pathological processes has been severely hampered by the lack of specific targeting tools in vivo. Recent findings have shown that the dural sinus and its adjacent lymphatic vessels act as a neuroimmune interface. Notably, the cellular and functional heterogeneity of extrasinusoidal dural macrophages outside this immune hub is currently unclear. Therefore, we comprehensively characterized these cells using single-cell transcriptomics, fate mapping, confocal imaging, clonal analysis and transgenic mouse lines. Extrasinusoidal dural macrophages were clearly distinct from leptomeningeal and CNS parenchymal macrophages in terms of their origin, expansion kinetics and transcriptional profiles. Lastly, functional studies demonstrated that during autoimmune neuroinflammation, extrasinusoidal dural macrophages perform efferocytosis of granulocytes. Our results highlight a previously unappreciated myeloid cell diversity and provide insights into the brain’s innate immune system.

Characterization of meningeal type 2 innate lymphocytes and their response to CNS injury

Project description:The meningeal space is occupied by a diverse repertoire of innate and adaptive immune cells. CNS injury elicits a rapid immune response that affects neuronal survival and recovery, but the role of meningeal inflammation in CNS injury remains poorly understood. Here we describe group 2 innate lymphoid cells (ILC2s) as a novel cell type resident in the healthy meninges that is activated following CNS injury. ILC2s are present throughout the naïve mouse meninges, though are concentrated around the dural sinuses, and have a unique transcriptional profile relative to lung ILC2s. After spinal cord injury, meningeal ILC2s are activated in an IL-33 dependent manner, producing type 2 cytokines. Using RNAseq, we characterized the gene programs that underlie the ILC2 activation state. Finally, addition of wild type lung-derived ILC2s into the meningeal space of IL-33R-/- animals improves recovery following spinal cord injury. These data characterize ILC2s as a novel meningeal cell type that responds to and functionally affects outcome after spinal cord injury, and could lead to new therapeutic insights for CNS injury or other neuroinflammatory conditions.

RNA Sequencing of sorted CD31+ meningeal endothelial cells from naïve Lewis rats

Project description:The meninges, comprising the leptomeninges (pia and arachnoid layers) and the pachymeninx (dura layer), participate in CNS autoimmunity but their relative contributions remain unclear. Here, we report on findings in animal models of CNS autoimmunity and in multiple sclerosis patients, where, in chronic disease, the leptomeninges were highly inflamed and showed structural changes, while the dura mater was only marginally affected. Although dural vessels were leakier than leptomeningeal vessels, effector T cells adhered more weakly to the dural endothelium. Furthermore, local antigen presenting cells presented myelin and neuronal autoantigens less efficiently and the activation of autoreactive T cells was lower in dural than leptomeningeal layers, preventing local inflammatory processes. Direct antigen application was required to evoke a local inflammatory response in the dura. Together, our data demonstrate an uneven involvement of the meningeal layers in CNS autoimmunity, in which effector T cell trafficking and activation are functionally confined to the leptomeninges, while the dura remains largely shielded from CNS autoimmune processes.

Cellular and molecular signatures of the vascular microenvironment define the pre-metastatic brain and meninges [MERFISH]

Project description:The contribution of resident brain and meningeal cells in facilitating brain metastasis remains underappreciated. Here, we characterise the pre-metastatic molecular changes that occur in brain and meningeal resident cells in mouse models of breast cancer using single-cell and spatial transcriptomics. Increased inflammatory alterations preceding metastasis were identified in bridging veins spanning the leptomeninges, forming adhesion hotspots by upregulating Icam1 and Vcam1. Furthermore, bridging veins and encapsulating leptomeningeal fibroblasts upregulate cell trafficking ligands, including chemokines. Brain metastasising tumour cells correspondingly upregulate adhesion counter-receptor LFA-1 and chemokine receptors, demonstrating an enhanced capacity to traffic towards altered brain vessels and stroma. Moreover, PD-L1+ immunosuppressive neutrophils infiltrate the dura and brain, coupled with upregulation of checkpoint molecule PD-1 in CD8+ T cells. Neutrophils furthermore upregulate VEGFA, driving angiogenesis and vascular remodelling. These results indicate that breast cancers can drive multiple alterations in the leptomeningeal and dural vasculature that collectively facilitate formation of brain metastases.
