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.

Paper
TLR7-dependent eosinophil degranulation links psoriatic skin inflammation to small intestinal inflammatory changes in miceExperimental & molecular medicine · 2024
Summary (written by the submitters)
Increased intestinal permeability can exacerbate psoriasis, a systemic inflammatory disease with complex pathogenesis. Using a mouse model of psoriasis elicited by the TLR7 ligand imiquimod, we found that psoriatic dermatitis was accompanied by small-intestinal inflammatory changes associated with eosinophil degranulation which led to impaired intestinal barrier integrity.

Inflammatory responses in the skin and small intestine were accelerated in mice that are prone to eosinophil degranulation. Caco-2 human intestinal epithelial cells treated with media containing eosinophil granule proteins exhibited signs of inflammation and damage. Imiquimod-induced skin and intestinal inflammatory changes were attenuated in eosinophil-deficient mice, and this attenuation was counteracted by eosinophil transfer. Imiquimod levels and eosinophil distribution were positively correlated in the intestine. TLR7-deficient mice did not show intestinal eosinophil degranulation and exhibited attenuated skin and small-intestinal inflammation following imiquimod application. These results suggest a TLR7-dependent bidirectional skin-to-gut communication in psoriatic inflammation, and that intestinal inflammatory changes can accelerate psoriasis.

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 GSE237610_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 PRJNA988261 and SRA study SRP446241. 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.
