What it is
Single-cell RNA-seqGene activity measured in thousands of individual cells, so cell types can be told apart. Read from the summary: GEO's own type field only says 'expression profiling by sequencing', so confirm it in the paper.
Organism
Mus musculus (mouse)
Samples
14 samples: 7 × Sorted mCAT MdMs CD45.2 CCR2creERT2/+ mcat lsl/wt dono vs 6 × Sorted wt MdMs CD45.1 donoGroups are read from the sample names, not from the paper. Check the list below.
Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Paper
Monocyte-derived macrophages drive neurological tissue damage through mitochondrial reactive oxygen speciesScience immunology · 2026
Summary (written by the submitters)
Reactive oxygen species (ROS) produced by mononuclear phagocytes (MPs) are widely believed to drive tissue damage in multiple sclerosis (MS), yet the distinct roles of central nervous system (CNS)-resident versus CNS-invading MPs remain unclear. Here, we combined single-cell profiling and conditional gene targeting to map and modulate ROS production across CNS MPs in a preclinical mouse model of MS.
Read the full summary ↓
We show that monocyte-derived macrophages (MdMs) exhibit a higher oxidative stress gene signature and produce more ROS than Mglia. Challenging previous assumptions, our findings reveal that phagocytic NADPH oxidase 2 is dispensable for neuroinflammation. In contrast, quenching mitochondrial ROS (mtROS) through mitochondria-targeted catalase (mCAT) expression in MdMs, but not in Mglia, ameliorated disease severity in acute neuroinflammation. While core phagocyte functions were unaltered in mCAT-expressing MdMs, our results demonstrate a direct neurotoxic role of mtROS. Together, we identify MdMs as the primary driver of ROS-mediated oxidative neurological tissue damage.

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 GSE326335_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 PRJNA1434700 and SRA study SRP682495. Searching any of these in the dataset finder brings you back here.

Study design
7 × Sorted mCAT MdMs CD45.2 CCR2creERT2/+ mcat lsl/wt dono vs 6 × Sorted wt MdMs CD45.1 dono

Supports a between-group comparison across 13 samples.

How we read this: 2 replicated groups read from 14 sample titles; they account for 13 of them. 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.
