Paper
Extrasinusoidal macrophages are a distinct subset of immunologically active dural macrophagesScience immunology · 2024
Summary (written by the submitters)
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.
Read the full summary ↓
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.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE278812_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1168964 and SRA study SRP536642. Searching any of these in the dataset finder brings you back here.

How we read this: Read from 10 sample titles: 8 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
