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.

Summary (written by the submitters)
­­Neuro-immune circuits regulate innate and adaptive immunity at barrier surfaces, however the differential impact of these circuits on proinflammatory versus tissue-protective responses remains poorly defined. We identify that enteric neurons produce CGRP-related adrenomedullin 2 (ADM2), and identify a previously unrecognized role for the ADM2-ADM2 receptor pathway in promoting intestinal tissue-protective functions of group 2 innate lymphoid cells (ILC2s).
Read the full summary ↓
Genomic or ILC2-intrinsic deletion of ADM2 receptor subunits resulted in a significant reduction in tissue-protective ILC2 responses, defective amphiregulin (AREG) production and increased susceptibility to intestinal damage and inflammation. Conversely, therapeutic delivery of recombinant ADM2 elicited tissue-protective AREG production in ILC2s and limited intestinal inflammation. Expression of genes encoding human ADM2 receptor (CALCRL and RAMP3) was altered in IBD patients and associated with reduced expression of AREG in ILC2s. Collectively, these findings identify that the ADM2-ADM2 receptor pathway can promote tissue-protective functions of ILC2s in the context of intestinal damage and inflammation.

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 GSE271362_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 PRJNA1130984 and SRA study SRP517633. Searching any of these in the dataset finder brings you back here.

Study design
11 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 11 sample titles: 11 distinct titles with little repetition. 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.
