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
18 samples: 5 conditions, mostly with about 5 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.

Summary (written by the submitters)
Plasmacytoid dendritic cells (pDCs) are major producers of type I/III interferons. Since these cytokines are crucial for antiviral defense, it is assumed to be also the case for pDCs. However, robust evidence supporting this dogma is scarce. Genetic mutations or pharmacological manipulations causing pDC loss or disrupting their interferon production affect other immune cells, which could confound interpretation.

To overcome this bottleneck, we engineered pDC-less mice, specifically and constitutively devoid of pDCs because expressing diphteria toxin under coordinated control by the Siglech and Pacsin1 genes co-expressed only in pDCs. pDC-less mice mounted protective intrinsic and innate immune responses against systemic infection with mouse cytomegalovirus, and were more resistant to intranasal infection with influenza virus and SARS-CoV2. Thus, contrary to dogma, pDCs and their interferon production proved dispensable or deleterious during systemic or respiratory viral infections. pDC-less mice will enable rigorously revisiting the roles of pDCs in health and 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 GSE302124_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 PRJNA1289033 and SRA study SRP599427. Searching any of these in the dataset finder brings you back here.

Study design
5 conditions, mostly with about 5 replicates each
D2-TgK18 ×5 D4-TgK18 ×5 NI-TgK18 ×3 D1-TgK18 ×3 D6-TgK18 ×2

Supports a between-group comparison across 18 samples.

How we read this: 5 replicated groups read from 18 sample titles; they account for 18 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.
