Paper
Spatially restricted immune and microbiota-driven adaptation of the gutNature · 2024
Summary (written by the submitters)
The intestine is characterized by an environment where host requirements for efficient nutrient and water absorption are consequently paired with the requirement to establish and maintain tolerance to the outside environment. The organ is anatomically organized into the small intestine (SI) which specializes in nutrient absorption and the colon which specializes in water resorption.

The transcriptional and cellular circuits that define intestinal regionalization and their robustness, adaptability, and resilience to changes in the local environment are not well characterized. Here, we generated a comprehensive survey of the spatial and cellular landscape of the murine intestine to demonstrate the steady state transcriptional landscape of the murine intestine is robust, adaptable, and resilient to perturbation. We characterized the transcriptional landscape of the full length of the intestine and show it is established independently of the microbiota and is not under circadian regulation. In the colon, these regional circuits were characterized by unique subsets of structural cells. Moreover, we identified a spatial adaptation to the microbiota in the colon characterized by the emergence of unique structural cell subsets including an enterocyte, fibroblast, and goblet cell, with the later two co-occurring in space. Employing a model of acute spatiotemporal damage allowed us to show the spatial landscape and adaptations we identified are both resilient to inflammation. Our results demonstrate that intestinal circuits are under host control and spatial adaptations in the steady state as well as in the process of recovery from tissue damage in the inflamed state are primarily characterized by changes to structural cell types such as epithelial and stromal cells.

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 GSE245315_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: Single-cell studies usually ship their counts as 10x files (matrix.mtx, barcodes.tsv, features.tsv), an .h5 file, or an .rds / .h5ad object that Seurat or Scanpy can open. Look for those among the supplementary files.

Also filed as BioProject PRJNA1027816 and SRA study SRP466212. Searching any of these in the dataset finder brings you back here.

Study design
26 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 26 sample titles: 26 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.
