Summary (written by the submitters)
Ulcerative colitis (UC) is a chronic inflammatory condition of the colon, driven by mucosal immune and stromal subsets, culminating in epithelial injury. Vedolizumab (VDZ) is an anti-integrin monoclonal antibody that is effective for treating UC. VDZ is known to inhibit lymphocyte trafficking to the intestine, but its broader effects on other cell subsets are less defined.

To identify the inflammatory cells that contribute to colitis and are affected by VDZ, we performed a single-cell and spatial transcriptomic and proteomic analysis of peripheral blood and colonic biopsies in healthy controls (HC) and patients with UC on VDZ or other therapies. We identified significant effects of VDZ on mononuclear phagocyte (MNP) subsets, in addition to modest effects on lymphocyte populations. Spatial transcriptomics and proteomics of formalin-fixed, paraffin-embedded (FFPE) biopsies at single-cell resolution demonstrated trends towards increased abundance and proximity of activated MNP and fibroblast subsets in active colitis compared to HC, with inhibition by VDZ. Spatial transcriptomics of archived FFPE specimens pre-treatment identified epithelial-, MNP-, and fibroblast-enriched genes related to VDZ response versus non-response, and these were validated in an external, publicly accessible bulk transcriptomic dataset. Single cell and spatial multi-omics highlight important roles for myeloid, stromal, and epithelial subsets in UC.

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 GSE250488_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 PRJNA1054167. Searching any of these in the dataset finder brings you back here.
