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
15 samples: 5 × PBS_TAC vs 5 × Dol_TAC vs 5 × EVP_TACGroups 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)
Autonomic neuronal dysfunction is associated with heart failure (HF). Here, we report that targeted vagal nerve stimulation (VNS) using optogenetics attenuates cardiac remodelling and HF induced by pressure overload. Unbiased approaches revealed that VNS decreased the proportion of the Ccrl2+ macrophage subset, which derived from myeloid monocytes and exhibited a distinct tumour necrosis factor-alpha (TNFα)-responsive, pro-hypertrophic, and profibrotic signature.

Elimination of Ccrl2+ macrophages prevented cardiac remodelling and HF. Functional characterisation by Ccrl2+ macrophage-specific overexpression or global genetic loss of α7 nicotinic acetylcholine receptor (α7nAChR) highlighted its crucial contribution to VNS-mediated cardioprotection. Mechanistically, activation of α7nAChR inhibited the TNFα responsiveness through upregulated expression of the transcription factor NRF2. Cardiac Ccrl2+ macrophages and TNFα-responsive proteins were positively correlated with cardiac remodelling and dysfunction in humans. Finally, an α7nAChR agonist effectively blocked the development of HF. These results suggest that the vagal neuroimmune axis modulates heart failure and is a promising target for treatment.

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.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE296034_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 PRJNA1257340 and SRA study SRP582399. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 15 samples.

How we read this: 3 replicated groups read from 15 sample titles; they account for 15 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.
