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
28 samples: 28 samples, each with a distinct title — no replicated groupsGroups 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.
Paper
Neutrophil trapping and nexocytosis, mast cell-mediated processes for inflammatory signal relayCell · 2024
Summary (written by the submitters)
Neutrophils are activated and attracted to sites of anaphylaxis by degranulating tissue resident mast cells. After they facilitate inflammation and an anti-microbial immune response. However, the dynamics of neutrophils and direct interactions with mast cells are poorly investigated yet. By approaching 2-photon intravital microscopy and live cell imaging, we show that degranulating mast cells induce neutrophil swarming by releasing leukotriene B4 (LTB4).
Read the full summary ↓
Attracted neutrophils interact with mast cells and surprisingly penetrate inside mast cells where they are stably trapped inside mast cell granules. We call this novel form of cell-in-cell structure “Mast Cell Intracellular Trap” (MIT). Trapped neutrophils and mast cells are both viable in the first 12 hours after MIT formation. However, neutrophils start to dye after 12hrs and translatome analysis of mast cells revealed improved mast cell metabolism and recovery. Therefore, neutrophils allow a faster and more efficient mast cell re-stimulation. Furthermore, mast cells get more resistant to extracellular nutrient limitations. Thus, beside their inflammatory role in anaphylaxis, neutrophils support mast cell recovery by forming a cell in cell structure. This might affect chronic inflammation and recurrent infections.

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 GSE168801_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 PRJNA714063 and SRA study SRP310407. Searching any of these in the dataset finder brings you back here.

Study design
28 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 28 sample titles: 28 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.
