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
12 samples: 3 × Control vs 3 × Klf2_cKO vs 3 × b7_posi vs 3 × b7_negaGroups 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
KLF2 expression in IgG plasma cells at their induction site regulates the migration programThe Journal of experimental medicine · 2025
Summary (written by the submitters)
We found that, among newly generated IgG plasma cells, integrin b7hi marks plasma cells prone to home to the bone marrow, whereas integrin b7lo cells remain in secondary lymphoid organs. Moreover, we also found that the differences in KLF2 expression between b7hi and b7lo populations in secondary lymphoid organs is likely to explain that only integrin b7hi plasma cells can egress.

Next, to look for the functional target(s) downstream of KLF2 involved in egress of newly generated plasma cells, we carried out RNA-seq analysis of KLF2-sufficient and -deficient splenic plasma cells. Wildtype control splenic plasma cells were further divided into integrin b7hi and b7lo populations. We identified S1pr1 and Itgam as functional targets downstream of KLF2.

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 GSE266441_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 PRJNA1107186 and SRA study SRP505438. Searching any of these in the dataset finder brings you back here.

Study design
3 × Control vs 3 × Klf2_cKO vs 3 × b7_posi vs 3 × b7_nega

Supports a between-group comparison across 12 samples.

How we read this: 4 replicated groups read from 12 sample titles; they account for 12 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.
