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)

16 samples: 4 × lung epithelia, vehicle, noMAV, dono vs 4 × lung epithelia, IL13, noMAV, dono vs 4 × lung epithelia, vehicle,MAV, dono vs 4 × lung epithelia, IL13,MAV, donoGroups 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)
Human airway epithelia (HAE) undergo inflammation-induced remodeling in chronic lung diseases such as asthma and chronic bronchitis. The role of type 2 inflammation-induced epithelial remodeling in SARS-CoV-2 infection and the course of COVID-19 is unclear, moreover, there is discrepancy in the literature regarding the potential benefit of treatments that modulate type 2 inflammation.

We investigated the role of IL-13-induced inflammation on SARS-CoV-2 binding/entry, replication, and host response in primary HAE cells in vitro and in a model of mouse-adapted SARS-CoV-2 in vivo. IL-13 protected airway epithelial cells from SARS-CoV-2 infection in vitro by decreasing the abundance of ACE2- expressing ciliated cells rather than by neutralization in the airway surface liquid or by interferon-mediated antiviral effects. In contrast, IL-13 worsened the severity of disease in mice in vivo; the effects were mediated by eicosanoid signaling and were abolished in mice deficient in the phospholipase A2 enzyme PLA2G2D. We conclude that IL-13-induced inflammation affects multiple steps of SARS-CoV-2-induced disease pathogenesis. Whereas IL-13-induced inflammation may be protective against initial infection at the airway epithelium, it enhances disease severity once infection progresses in vivo; blockade of IL-13 and/or eicosanoid signaling may be protective against progression to severe lung 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 GSE249304_RAW.tar (it can run to tens of gigabytes).

All supplementary files ↗ Whole study · RAW.tar ↓
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 PRJNA1048482 and SRA study SRP475682. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 16 samples.

How we read this: 4 replicated groups read from 16 sample titles; they account for 16 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.
