Differentiation of T-regulatory type 1 cells into an immunoregulatory Foxp3+ subset distinct from conventional FoxP3+ T-regulatory cells

Project description: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.

Comparative proteomic analysis of mouse CD4+Foxp3+ regulatory T cells and CD4+Foxp3- conventional T cells

Project description:In this study, we compared the proteomes of mouse CD4+Foxp3+ regulatory T cells (Treg) and CD4+Foxp3- conventional T cells (Tconv) in order to build a data set of proteins differentially regulated in these two cell populations. The data set contains mass spectrometry results from the analysis of 7 biological replicates of Treg/Tconv cell samples purified by flow cytometry, each experiment performed from a pool of 4-5 mice. Global proteomic analysis of each sample was performed by single-run nanoLC-MS/MS, using chromatographic separation of peptides on 50cm C18 reverse-phase columns, with either a 480min gradient on LTQ-Velos orbitrap mass spectrometer (replicates 1 and 2) or a 300min gradient on Q-Exactive orbitrap mass spectrometer (replicates 3-7). Several MS injection replicates were performed for some experiments, leading to 27 raw files composing the data set. The detailed description of each analysis (file name, sample type, biological replicate number, MS technical replicate number, MS instrument used, sample name in MaxQuant ouput) is given in the table “Files list.txt”.

Immune Gene Expression Profile of Conventional and Regulatory T cells

Project description:Understanding human regulatory T cells (Tregs) heterogeneity may identify markers of disease pathogenesis and facilitate the development of optimized cellular therapeutics. To better elucidate human Treg subsets, we conducted direct transcriptional profiling of CD4+FOXP3+Helios+ thymic-derived Treg (tTreg) and CD4+FOXP3+Helios- peripherally-induced Treg (pTreg), followed by comparison to CD4+FOXP3-Helios- T conventional (Tconv) cells. This analysis revealed that the coinhibitory receptor T-cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domain (TIGIT) was highly expressed on tTreg. In this study CD4 T cells were stained for the Treg-associated transcription factors FOXP3 and Helios, and subsequently FACS sorted to yield three populations: tTreg (CD4+FOXP3+Helios+), pTreg (CD4+FOXP3+Helios–) and the reference population Tconv (CD4+FOXP3–Helios–). A direct transcriptional profile was obtained from the recovered RNA from the populations defined as tTreg, pTreg, and Tconv.

An inherently bi-functional subset of Foxp3+ Treg/T-helper cells is controlled by the transcription factor Eos

Project description:At sites of inflammation, certain Foxp3+ Tregs have the ability to alter their phenotype and become pro-inflammatory helper/effector cells, without losing Foxp3 expression. We show that this functional reprogramming is controlled by the transcription factor Eos (Ikzf4), an obligate co-repressor for Foxp3. The ability to reprogram was restricted to a specific subset of Foxp3+ Tregs, arising as early as the thymus and identifiable by short half-life of Eos at rest, characteristic cell-surface markers (CD38+CD69+CD103NEG) and a distinct pattern of DNA methylation. Mice made selectively deficient in this subset of Eos-labile Tregs became markedly impaired in their ability to cross-present new antigens and prime CD8+ T cells. Downregulation of Eos and consequent Treg reprogramming was prevented by the immunoregulatory enzyme IDO, via activation of the aryl hydrocarbon receptor (AhR). Thus, the Foxp3+ lineage contains a committed subset of Tregs that are constitutively primed for conversion into biologically important helper cells. Cells from thymus or spleen were incubated for 1 hr with cycloheximide (CHX), then CD4+GFP+ Tregs were FACS-sorted into Eos-labile (CD38+CD103NEG) and Eos-stable (CD103+CD38NEG) subsets. Control CD4+GFPNEG (non Treg) cells were sorted from spleen. Genome-wide differential methylation analysis was performed using Reduced Representation Bisulfite Sequencing (RRBS). The genomic DNA from each sample was digested with the methylation-insensitive restriction enzyme MspI (restriction site, CCGG) and ligated to Illumina sequencing adaptors containing methylated cytosine residues. The ligated MspI fragments were size-selected, treated with sodium bisulfite, and amplified by PCR. The PCR products were purified and sequenced using Illumina HiSeq 2000 sequencer with a read length of 100bp.
