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 × IgM plasma cells vs 5 × IgG1 plasma cellsGroups 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)
In a typical primary immune response, the BCR is brought about by IgM to IgG isotype switching, wherein B cells switched to IgG give rise to more long-lived plasma cells (LLPCs). How such isotype-driven bias takes place still remains unclear.
Read the full summary ↓
Here, we showed that IgG1 germinal center (GC) B cells presented higher levels of antigens to Tfh cells, making the resultant plasma cells more proliferate than IgM ones, and that BCR signal through IgM conferred more Bim-dependent apoptosis on their plasma cells, together dominating the numbers of IgG1 over IgM plasma cells in the secondary lymphoid tissues. In addition, IgG1 plasma cells were more prone to migrate to bone marrow than IgM ones. Hence, our findings suggest that differential activities in antigen presentation and signaling through IgG1 type BCRs contribute to enrichment of IgG1 plasma cells in the bone marrow long-lived plasma cell compartment.

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 GSE312596_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 PRJNA1374270 and SRA study SRP651544. Searching any of these in the dataset finder brings you back here.

Study design
5 × IgM plasma cells vs 5 × IgG1 plasma cells

Supports a between-group comparison across 10 samples.

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