Summary (written by the submitters)
Reconstitution of stem cells and enhancement of the barrier function of the gastrointestinal (GI) tract is critical to the resolution of intestinal acute graft-versus-host disease (aGvHD). Previously, our group has shown in murine models that type II innate lymphoid cells (ILC2) cells generate proteins in the GI tract that enhanced GI tract barrier function and diminished the expansion and function of pro-inflammatory donor cells when given to allogeneic stem cell transplant recipients.

Therefore, the infusion of donor ILC2 cells could treat or prevent GI tract acute GvHD, but for this approach to be clinically applicable, robust expansion of a homogenous population of human ILC2 cells is needed. Here, we describe a method for the rapid expansion of a uniform population of human ILC2 cells which decrease GvHD in (NOD scid gamma mouse) NSG mice. The addition of IL-4 to the culture was critical to prevent the expansion of pro-inflammatory ILC1-like cells. Our approach should allow for the evaluation of human ILC2 cells to treat therapy-resistant GI tract acute GvHD.

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 GSE301227_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: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1284299. Searching any of these in the dataset finder brings you back here.
