Summary (written by the submitters)
Regulatory T cells (Tregs) play crucial roles in maintaining maternal immune tolerance to the semi-allogeneic fetus during pregnancy, but Treg population heterogeneity and tissue-specific functions in human decidua remain largely unknown. Here, we conducted single-cell transcriptomic and T cell receptor sequencing of CD4+ T cells from first-trimester decidua and matched peripheral blood of pregnant women.

These analyses identified a highly activated, immunosuppressive CCR8+ Treg subset specifically enriched in decidua (dTregs). CCR8+ dTregs are decreased in recurrent pregnancy loss (RPL) patients and abortion-prone model mice. Depletion of this subset with anti-CCR8 antibodies alters the decidual immune profile, increasing susceptibility to fetal loss. The CCR8 ligand, CCL1, is mainly produced by decidual CD49a+ NK cells and is also significantly decreased in RPL patients. By characterizing the landscape of dTregs in human early pregnancy, we identified CCR8+ dTregs as crucial for maintaining maternal-fetal tolerance, suggesting new potential strategies for RPL diagnosis and therapy.

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 GSE252187_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.

Also filed as BioProject PRJNA1058460 and SRA study SRP480491. Searching any of these in the dataset finder brings you back here.

Study design
32 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 32 sample titles: 32 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.
