Induced regulatory B cells stably expressing IL-10 cure CNS autoimmunity by targeting microglia

ABSTRACT: B cells can control autoimmunity through interleukin(IL)-10 production. However, there is no protocol to efficiently generate IL-10-producing B cells, which limits the understanding of their differentiation and their development for cell therapy. To overcome this limitation, we performed a high throughput screen and identified a novel small molecule enabling the induction of quasi pure and stable IL-10-producing B cells. These B cells prevented the development of experimental autoimmune encephalomyelitis and cured recipient mice from disease within a few days upon administration at the peak of clinical signs. Their therapeutic effect involved IL-10 provision to microglia and was independent of their cognate interaction with CD4+ T cells. This study reports the generation of induced regulatory B cells (iBregs) for cell therapy against immune-mediated inflammatory diseases.

Prevention and cure of rotavirus infection via TLR5/NLRC4-mediated production of IL-22 and IL-18

Project description:Activators of innate immunity may have potential to combat a broad range of infectious agents. We report that treatment with bacterial flagellin prevented rotavirus (RV) infection in mice and cured chronically RV-infected mice. Protection was independent of adaptive immunity and interferon (IFN, type I and II) and required flagellin receptors Toll-like receptor 5 (TLR5) and NOD-like receptor C4 (NLRC4). Flagellin-induced activation of TLR5 on dendritic cells elicited production of the cytokine interleukin (IL)-22, which induced a protective gene expression program in intestinal epithelial cells. Flagellin also induced NLRC4-dependent production of IL-18 and immediate elimination of RV-infected cells. Administration of IL-22 and IL-18 to mice fully recapitulated the capacity of flagellin to prevent or eliminate RV infection, and thus holds promise as a broad-spectrum antiviral agent.

Molecular and functional heterogeneity of IL-10-producing CD4+ T cells [Mouse SMART-seq2]

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.

Expression data from splenic IL-10 positive and IL-10 negative B cells of C57BL/6

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.

Human peripheral IL-10-secreting vs non- IL-10-secreting B cells

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.

RNA-seq of Tfh IL21+ single producers and Tfh IL21+ IL10+ double producers

Project description:During chronic viral infection, the inflammatory function of CD4 T cells becomes gradually attenuated. Concurrently, Th1 cells progressively acquire the capacity to secrete the cytokine IL-10, a potent suppressor of antiviral T cell responses. To determine the transcriptional changes that underlie this T cell adaption process, we applied a single-cell RNA-sequencing approach and assessed the heterogeneity of IL-10-expressing CD4 T cells during chronic infection. Unexpectedly, our analyses revealed an IL-10-producing population with a robust Tfh-signature. Using IL-10 and IL-21 double-reporter mice, we further demonstrate that IL-10+IL-21+co-producing Tfh cells arise predominantly during chronic but not acute LCMV infection. Importantly, depletion of IL-10+IL-21+co-producing CD4 T cells or deletion of Il10 specifically in Tfh cells resulted in impaired humoral immunity and viral control. Mechanistically, B cell-intrinsic IL-10 signaling was required for sustaining germinal center reactions. Lastly, we demonstrate that IL-27 and type I IFNs differentially regulate the formation of this protective IL-10-producing Tfh subset. Thus, our findings elucidate a critical role for Tfh-derived IL-10 in promoting humoral immunity during persistent viral infection.
