Summary (written by the submitters)
Emerging evidence highlights regulatory T cell (Treg) heterogeneity in lymphoid and non-lymphoid tissues, but we have limited understanding of context-dependent functions and spatiotemporal regulators of heterogenous Treg states, especially during perinatal life when immune tolerance is established. Using single-cell transcriptomics profiling and experimental validations, we revealed that Vps34 is essential for orchestrating effector Treg (eTreg) transitional heterogeneity during perinatal life.

We found that loss of Vps34 reduced terminal eTreg accumulation in lymphoid tissues, associated with decreased generation of Treg cells in non-lymphoid tissues and development of an early-onset autoimmune disease. After perinatal life, Vps34-deficient eTreg accumulation was further impaired due to reduced survival, highlighting temporal regulation of eTreg heterogeneity and maintenance by Vps34. Accordingly, inhibition of Vps34 in mature Treg cells also disrupted immune homeostasis but boosted anti-tumor immunity. Mechanistically, multiomics profiling approaches uncovered that Vps34-orchestrated transcriptional and epigenetic remodeling promotes terminal eTreg programming. Further, via genetic deletion of the Vps34-interacting proteins Atg14 or Uvrag in Treg cells, we established that autophagy (via Atg14) but not endocytosis (via Uvrag) was required for the overall survival, but not transitional heterogeneity, of eTreg cells. Accordingly, mice with Treg-specific deletion of Atg14, but not Uvrag, had moderately disrupted immune homeostasis and reduced tumor growth, with Vps34 and Atg14-dependent gene signatures also being elevated in intratumoral Treg cells from human cancer patients. Collectively, our study reveals distinct Vps34-orchestrated signaling events that temporally regulate eTreg heterogeneity and functional adaptation and the pathophysiological outcomes on autoimmunity versus anti-tumor immunity.

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 GSE283256_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 PRJNA1192968 and SRA study SRP548637. Searching any of these in the dataset finder brings you back here.
