Project description:Invariant NKT (iNKT) cells comprise a heterogeneous group of terminally differentiated, non-circulating, tissue-resident T-lymphocytes that recognize glycolipids, including alpha-galactosylceramide (aGalCer), in the context of CD1d. Here, we show that murine and human liver-resident aGalCer/CD1d-binding iNKTs correspond to a novel Zbtb16+/Tbx21+/Gata3+/Maflow/Rorc– subset that exhibits profound plasticity. Repetitive encounters of these cells with intravenously-delivered aGalCer/CD1d-coated nanoparticles (NPs) trigger their differentiation into immunoregulatory, IL-10/IL-21-producing, Mafhigh cells expressing a T-regulatory type 1 (TR1)-like transcriptional signature.

Project description:Transcriptional profiling of mouse iNKT cells comparing wild type and Bcl11b deficient cell. The mice were treated with 4 μg of α-galactosylceramide. Goal was to determine the effects of transcription factor Bcl11b removal in iNKT cells. Intraperitoneal treatment with 4 μg of α-Galactosylceramide. Two pair of wild type (BCL11b F/F Vα14 transgenic) and Knock out (BCL11b F/F PLZF-Cre Vα14 transgenic)) mice were treated. Lymphocytes from spleen and liver were enriched and stain with PBS-57 Loaded CD1d tetramer. Pure iNKT cells were collected through cell sorter.

Project description:Invariant Natural Killer T (iNKT) cells are unconventional T cells that respond to microbe-derived glycolipid antigens. Our previous work suggested that the gut microbiota influenced iNKT cell functions during dextran sulfate sodium-induced colitis in mice. In this study, we showed that prenatal fecal transplant of different microbial community in specific pathogen-free mice led to transcriptional alterations in iNKT cells at steady state and following aGC-mediated activation in the offspring. In addition, iNKT cell transcriptional signatures also differed between male and female mice. Collectively, our findings suggest that sex and the intestinal microbiota are important factors that regulate iNKT cell homeostasis and responses.

Project description:We identified a novel subset of iNKT cells, C2 iNKT cells, that circulate in the periphery. Correspondingly, we characterized the tissue-resident iNKT cell subset, C1 iNKT cells. The development and terminal maturation of C2 iNKT cells completely depended on the thymic epithelial IL-15 niche, whereas C1 iNKT cells were regulated also by local IL-15 niches in peripheral tissues. C2 iNKT cells expressed high levels of genes related to cytotoxicity and exhibited more NK cell-like features. Functionally, C2 iNKT cells regulated self-antigen expression for immune tolerance in the thymus and mediated cancer immunosurveillance in the periphery.

Project description:We identified a novel subset of iNKT cells, C2 iNKT cells, that circulate in the periphery. Correspondingly, we characterized the tissue-resident iNKT cell subset, C1 iNKT cells. We also found the precursor of these two subsets of iNKT cells, C0 iNKT cells in thymus. The development and terminal maturation of C2 iNKT cells completely depended on the thymic epithelial IL-15 niche, whereas C1 iNKT cells were regulated also by local IL-15 niches in peripheral tissues. C2 iNKT cells expressed high levels of genes related to cytotoxicity and exhibited more NK cell-like features. Here we characterized the C2 iNKT cells, C1 iNKT cells, and C0 iNKT cells using RNA-seq. We also performed RNA-seq for CD4+ T cells, CD8+ T cells and NK cells as a comparison. To investigate the effect of CD4, we performed the RNA-seq for the CD4+ and CD4- C2 iNKT cells.

Project description:CD1d expression by thymocytes is required to select iNKT cells. When CD1d is expressed only on thymocytes (pLck-CD1d tg mice), iNKT cells are hyperresponsive to antigen stimulation suggesting that, in physiological conditions, these cells undergo functional education mediated by additional CD1d-expressing cells. Here, we investigated the mechanisms of this functional education. We find that peripheral iNKT cells from pLck-CD1d tg mice express significantly less SHP-1, a tyrosine phosphatase negatively regulating TCR signaling, than WT cells. iNKT cells from heterozygous SHP-1-mutated motheaten mice, displaying similar SHP-1 reduction as pLck-CD1d tg iNKT cells, are antigen-hyperresponsive. Restoring normal CD1d expression in pLck-CD1d tg mice normalizes SHP-1 expression and responsiveness of iNKT cells. In WT mice, iNKT cells upregulate SHP-1 and decrease responsiveness upon emigration from thymus to periphery. This depends on contacts with CD1d-expressing DCs. iNKT cell functional education is therefore controlled by DCs via tuning SHP-1 expression level in the periphery.
