What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.
Organism
Mus musculus (mouse)
Samples
19 samples: 6 conditions, mostly in triplicateGroups 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.

Summary (written by the submitters)
The experimental autoimmune encephalomyelitis (EAE) mouse model is widely used to study the pathophysiology of multiple sclerosis (MS), including brain inflammation and demyelination. This study investigates cell-type-specific transcriptional changes in oligodendrocytes, astrocytes, and microglia at day 30 post-induction of EAE using MOG peptide (amino acids 35–55) emulsified in complete Freund’s adjuvant (CFA) containing Mycobacterium tuberculosis, followed by pertussis toxin injections.
Read the full summary ↓
CFA control mice received only CFA and pertussis toxin, without MOG peptide. Oligodendrocytes, astrocytes, and microglia were isolated using magnetic-activated cell sorting (MACS) from brain and spinal cord of CFA-treated and EAE-induced mice. Bulk RNA sequencing was conducted to uncover transcriptional changes associated with EAE-induced demyelination. These findings will enhance our understanding of glial cell contributions to MS pathogenesis and help identify potential therapeutic targets.

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 GSE287323_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1212135 and SRA study SRP558166. Searching any of these in the dataset finder brings you back here.

Study design
6 conditions, mostly in triplicate
MOG_Ctrl_Astro ×4 CFA_Ctrl_OL ×3 MOG_Ctrl_OL ×3 CFA_Ctrl_Astro ×3 CFA_Ctrl_MG ×3 MOG_Ctrl_MG ×3

Supports a between-group comparison across 19 samples.

How we read this: 6 replicated groups read from 19 sample titles; they account for 19 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.
