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
Homo sapiens (human)
Samples
14 samples: 4 × SLCL_AMS vs 3 × SLCL_SMS vs 2 × SLCL_HC vs 2 × HC_LCLGroups 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
Multiple sclerosis patient-derived spontaneous B cells have distinct EBV and host gene expression profiles in active diseaseNature microbiology · 2024
Summary (written by the submitters)
Epidemiological studies have demonstrated that Epstein-Barr virus (EBV) is an etiologic risk factor, and perhaps prerequisite, for the development of MS. EBV establishes life-long latent infection in a subpopulation of memory B cells. Although B cells play a key role in the pathobiology of MS, EBV-associated mechanisms of B cell inflammation and disease pathogenesis in EBV (+) B cells from MS patients are not well characterized.

Accordingly, we obtained lymphoblastoid lines (LCLs) and spontaneous LCLs (SLCLs), distinguished by their transformation with lab strain (B95.8) or endogenous EBV, respectively, from MS patients and healthy controls to study host-virus interactions in B cells. Here, we use transcriptomics and genomics-based approaches to identify differences in EBV gene expression and regulation of both viral and cellular genes in LCLs compared to SLCLs and between SLCLs generated from healthy controls and MS patients during “active” or “stable” periods of disease activity. We demonstrate increased lytic gene expression in SLCLs derived from MS patient B cells, especially those generated from peripheral blood mononuclear cells (PBMCs) obtained during “active” disease.

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 GSE244313_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 PRJNA1022395 and SRA study SRP463837. Searching any of these in the dataset finder brings you back here.

Study design
4 × SLCL_AMS vs 3 × SLCL_SMS vs 2 × SLCL_HC vs 2 × HC_LCL

Supports a between-group comparison across 11 samples.

How we read this: 4 replicated groups read from 14 sample titles; they account for 11 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.
