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
10 samples: 5 × Experiment_2_antibiotics vs 3 × Experiment_2_controlGroups 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.

Gut-derived metabolites drive Th17 cell pathogenicity in multiple sclerosisCell reports · 2025
Summary (written by the submitters)
The gut-brain axis is an emerging factor in promoting multiple sclerosis (MS). However, the underlying mechanisms and strategies to target this axis are not established. Here, we investigated how the gut environment influences myelin-specific Th17 cell pathogenicity. We used the adoptive Th17 cell transfer experimental autoimmune encephalomyelitis (EAE) model and antibiotic treatment to modulate the intestinal microbiome.

We observed a reduced pathogenic Th17 cell signature in the colon of antibiotics-treated mice. Treatment with fecal filtrates enhanced myelin-specific Th17 cell encephalitogenic properties both in vitro and in vivo. Feces metabolomic profiling identified altered tryptophan-derived metabolites, including indole-3-carboxylate (I3CA). Oral I3CA supplementation accelerated EAE development and I3CA concentration in blood samples from persons with MS (PwMS) was associated with increased disease severity mirrored by increased serum neurofilament light chain levels. Altogether, our study shows that microbiota-derived metabolites play a key role in the intestine during neuroinflammation, offering potential therapeutic insights for PwMS.

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 GSE282316_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 PRJNA1188120 and SRA study SRP546218. Searching any of these in the dataset finder brings you back here.

Study design
5 × Experiment_2_antibiotics vs 3 × Experiment_2_control

Supports a between-group comparison across 8 samples.

How we read this: 2 replicated groups read from 10 sample titles; they account for 8 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.
