BLIMP-1-dependent differentiation of T follicular helper cells into Foxp3(+) T regulatory type 1 cellsFrontiers in immunology · 2025
Summary (written by the submitters)
T-regulatory type-1 (TR1) cells are a subset of interleukin-10-producing but FoxP3-negative Treg cells that arise in vivo in response to chronic antigenic stimulation. We have shown that repetitive systemic delivery of autoimmune disease-relevant peptide-major histocompatibility complex class II (pMHCII)-coated nanoparticles (pMHCII-NP) triggers the formation of large pools of disease-suppressing Foxp3– TR1 cells from cognate T-follicular helper (TFH) cell precursors.

Here we show that these Foxp3– TR1 cells spontaneously differentiate into a novel immunoregulatory Foxp3+ TR1 subset that inherits transcriptional and epigenetic hallmarks of their precursors and is distinct from other Foxp3+ Treg cell subsets described to date. Development of this novel Foxp3+ Treg cell subset, as is also the case for Foxp3– TR1 cells but not conventional Foxp3+ Treg cells, is BLIMP1-dependent. In a model of central nervous system autoimmunity, deletion of Il10 in the Foxp3+ TR1 subset, but not its FoxP3+ counterpart, reduces the therapeutic activity of pMHCII-NPs without impairing their pharmacodynamic activity. T cell-specific deletion of Prdm1 and deletion of Il10 in both the FoxP3– and FoxP3+ TR1 subsets almost completely abrogate the therapeutic activity of these compounds. Thus, the TFH-TR1 transdifferentiation pathway evolves through 4 distinct cellular states that culminate in the generation of IL-10-producing FoxP3– and FoxP3+ TR1 subsets in a BLIMP1-dependent manner. This transdifferentiation pathway represents a new target for therapeutic intervention in immunity and autoimmunity.

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 GSE252235_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: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Also filed as BioProject PRJNA1058984 and SRA study SRP480620. Searching any of these in the dataset finder brings you back here.
