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
14 samples: 7 × Bulk Tissue, TBI +3d vs 7 × Bulk Tissue, Sham +3dGroups 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.

NF-κB activation in astrocytes impairs wound healing after traumatic brain injury in male miceNature communications · 2026
Summary (written by the submitters)
Traumatic brain injury (TBI) is a complex condition in which multiple pathophysiological mechanisms influence the course of the disease. After the primary mechanical impact, neuroinflammatory reactions of glial cells along with infiltrating peripheral immune cells mainly determine the overall clinical outcome. However, these secondary processes and their molecular determinants promoting either beneficial or detrimental consequences are not well-defined.
Read the full summary ↓
Here, we show that TBI-mediated NF-κB activation in astrocytes impairs their homeostatic functions and acts as a key regulator of multiple post-traumatic responses in mice. We determined striking deficits in CNS scar formation after TBI using a combination of NF-κB-reporter mice, conditional mouse models allowing astrocytic NF-κB modulation, and analysis of transcriptomic signatures. Importantly, the development of wound healing deficits depends on paracrine signaling of NF-κB-activated astrocytes and cross-responsive microglial cells.Our findings identify astrocytic NF-κB activation as a critical pathological amplification factor interfering with the restoration of CNS integrity at wound lesion sites.

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 GSE276422_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 PRJNA1157330 and SRA study SRP530563. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 14 samples.

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