Project description:Transcriptional profiling of human peripheral B cell subsets sorted by flow cytometry based on the secretion of IL-10 in response to CpG2006 stimulation. Goal was to identify molecular markers to distinguish IL-10-producing B cells form non-IL-10-producing B cells. Two-condition experiment, non-IL-10-secreting B cells vs. IL-10-secreting B cells. Healthy donors. Biological replicates: 6

Project description:Background information: Antibody responses to most infectious and food protein antigens depend on help to B cells from specialised T follicular helper (Tfh) cells. A subset of Foxp3+ regulatory T cells (Tregs) has been described in mice, with a prominent role in repressing germinal center reactions that are critical for memory B cell formation and long-lived antibody responses. These specialised Tregs co-opt the Bcl-6-dependent Tfh differentiation pathway in order to access the B cell-rich follicles and have therefore been designated as T follicular regulatory (Tfr) cells. Preliminary results: We identified a unique Bcl-6-expressing follicular regulatory T cell in human secondary lymphoid tissue, designated hereafter as Tfr2 cells, that lacks Foxp3 expression and the thymic-imprinted Foxp3 methylation pattern, but shares expression of key Treg molecules. Interestingly, 25% of these cells are the predominant source of T cell-derived IL-10 in human tonsil, an important cytokine with immunomodulatory properties. Aims of this study: We performed transcriptional profiling using affymetrix microarrays to interrogate wether IL-10 producing vs non producing human Tfr2 cells were fundamentally different subsets. 2 cell types (IL-10+ vs IL10- TFR2 cell subsets) obtained from 3 different tonsil donors (biological replicates)

Project description:Human IL-10– and IL-10+ TH17 clones maintained their pro- or anti-inflammatory characteristics after long-term culture. There were similarities between human IL-10– vs. IL-10+ TH17 clones and mouse pathogenic vs. non-pathogenic TH17 cells.

Project description:The mechanisms in regulating the development of IL-10 producing B cells are largely unknown. To clarify which transcription factor is critical for regulation of IL-10 producing B cells, we compared the gene expression profile of IL-10 positive B cells and IL-10 negative B cells. Transcriptional repressor Prdm1/Blimp1 is known to play a key role in controlling B ells differentiation. We show a dual role for Blimp-1 in IL-10 expression in IL-10 producing B cells and plasmablasts.

Project description:IL-10 is a prototypical anti-inflammatory cytokine, which is fundamental to the maintenance of immune homeostasis, especially in the intestine. There is an assumption that cells producing IL-10 have an immunoregulatory function. However, here we report that IL-10-producing CD4+ T cells are phenotypically and functionally heterogeneous. By combining single cell transcriptome and functional analyses, we identified a subpopulation of IL-10-producing Foxp3Neg CD4+ T cells that displays regulatory activity unlike other IL-10-producing CD4+ T cells, which are unexpectedly pro-inflammatory. The combinatorial expression of co-inhibitory receptors is sufficient to discriminate IL-10-producing CD4+ T cells with regulatory function from others and to identify them across different tissues and disease models in mice and humans. These regulatory IL-10-producing Foxp3Neg CD4+ T cells have a unique transcriptional program, which goes beyond the regulation of IL-10 expression. Finally, we found that patients with Inflammatory Bowel Disease (IBD), demonstrate a deficiency in this specific regulatory T-cell subpopulation.
