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
35 samples: 12 conditions, mostly in triplicateGroups 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)
Group 2 innate lymphoid cells (ILC2s) are thought to develop in the bone marrow and fetal liver. However, increasing evidence supports the presence of thymic ILC2s in mice and humans. In this study, we introduce a novel fate-mapping mouse model designed to track thymic ILC2s in peripheral tissues. Thymic ILC2s are labeled by ZsGreen whose expression is induced by Cd3giCre.

While they are present in the thymus and peripheral tissues, they are not found in the bone marrow. These cells are predominantly abundant during the neonatal stage, when the intense alveolarization and tissue remodeling occur. RNA sequencing revealed elevated expression of cytokine genes, Il13 and Il4, as well as Klrg1 in these cells. They also harbor TCR gene rearrangements suggesting common developmental pathways with T cells. Furthermore, we demonstrate that neonatal ILC2s play a critical role in macrophage polarization in a naphthalene-induced injury lung model. These findings help explore the differences between pediatric and adult immunity and future therapeutic strategies.

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 GSE326762_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 PRJNA1446866 and SRA study SRP688639. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 35 samples.

How we read this: 12 replicated groups read from 35 sample titles; they account for 35 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.
