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
75 samples: 17 conditions, mostly with about 4 replicates eachGroups 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.

Sterile production of interferons in the thymus affects T cell repertoire selectionScience immunology · 2024
Summary (written by the submitters)
Type I interferons (IFN-I) are transiently induced during infections, but were reported to be produced in the thymus at steady state. We found that developing thymocytes displayed an IFN-I signature that was mainly dependent on IFN-β. Using Ifnb1 reporter mouse strains, we observed IFN-β expression in a small population of medullary thymic epithelial cells (mTEC), which was AIRE-dependent and peaked at 2-3 weeks of age.

To study the cellular response to thymic IFN, we used a Mx1gfp reporter mouse strain and found that the IFN response in T cells and myeloid cells was abrogated by IFNaR deficiency, whereas the response in B cells and dendritic cells was dependent on both IFNaR and IFNlR. Furthermore, single-cell RNAseq analysis revealed dramatic transcriptional changes in all thymic APCs in IFNaR/IFNlR deficient mice, and a loss of CCR7+ cDC1 cells. Together, these results show that steady state IFN-I and IFN-III signaling drives a gene-expression program in thymic APCs that shapes the thymic microenvironment.

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 GSE192715_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 PRJNA792824 and SRA study SRP352743. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 75 samples.

How we read this: 17 replicated groups read from 75 sample titles; they account for 75 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.
