A single cell analysis of porcine thymopoiesis and thymic iNKT cells

ABSTRACT: Many aspects of the porcine immune system remain poorly characterized which poses a barrier to improving swine health and utilizing pigs as preclinical models. Here, we employed single-cell RNA sequencing (scRNA-seq) to create a cell atlas of the postnatal pig thymus. Our data found conserved features as well as species-specific differences in cell states and cell types compared to human thymocytes. We also describe several unconventional T cell types with gene expression profiles associated with innate effector functions. This includes a cell census of >11,000 differentiating invariant natural killer T (iNKT) cells, which revealed that the functional diversity of pig iNKT cells differs substantially from the paradigm of iNKT0/1/2/17 subset differentiation established in mice. Collectively, our data characterizes key differentiation events in porcine thymopoiesis and iNKT cell maturation, which provide new insights into pig T cell development.

The intestinal microbiota modulates the transcriptional landscapes of iNKT cells

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.

RNA sequencing of WT and Uhrf1 KO iNKT cells

Project description:Deletion of Uhrf1 resulted in stage 1-specific defects during iNKT cell development. To investigate the molecular mechanism, we sorted WT and Uhrf1-KO stage 1 iNKT cells and performed RNA-seq. By comparing gene expression profile, we found metabolic defects in Uhrf1-KO stage 1 iNKT cells. The expression of CD71 (Tfrc), two subunits of CD98 (Slc3a2 and Slc7a5) and Glut3 (Slc2a3) was reduced in stage 1 iNKT cells. Besides, the downstream pathways of AKT-mTOR axis were significantly reduced. Collectively, our results suggest that Uhrf1 is required for iNKT cell development by regulating the Akt-mTOR signaling pathway. We first sorted WT and Uhrf1-KO stage 1 iNKT cells, extracted the mRNA and performed RNA-seq. We then analyzed the differentially expressed genes and performed KEGG pathway analysis. We used RT-PCR to verify the expression of the key nutrient related genes (Tfrc, Slc3a2, Slc7a5 and Slc2a3) and used flow cytometry to test the protein level of metabolic related molecules. Besides, we also analyzed the expression of genes of mTOR downstream pathways to demonstrate that Uhrf1 mediated AKt-mTOR axis regulates iNKT cell development.

Mouse iNKT cell: Wild type Vs Bcl11b deficient

Project description:Transcriptional profiling of mouse iNKT cells comparing wild type and Bcl11b deficient cell. The mice were treated with 4 Î¼g of Î±-galactosylceramide. Goal was to determine the effects of transcription factor Bcl11b removal in iNKT cells. Intraperitoneal treatment with 4 Î¼g of Î±-Galactosylceramide. Two pair of wild type (BCL11b F/F VÎ±14 transgenic) and Knock out (BCL11b F/F PLZF-Cre VÎ±14 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.

Expression data of hepatic iNKT cells from pLck-hCD1d transgenic mice

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. Hepatic iNKT cells from wild-type and transgenic mice (expressing hCD1d molecule under the pLck promoter)

RNA-seq of human iNKT cell lines primed with aGalCer vs Fusobacterium nucleatum

Project description:We performed RNA sequencing of primary human iNKT cell lines pulsed with Fn or αGalCer, the prototype agonist of iNKT cells. Fn-primed iNKT cells showed an enriched neutrophil chemotaxis gene signature, including the chemokine C-X-C and C-C motif ligand family genes. αGalCer-primed iNKT cells presented an IFNγ/cytotoxic-related gene signature.

Gene expression profiling of CD244+CXCR6+ C2 iNKT cell subet and CD244-CXCR6+ C1 iNKT cell subset

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.

Recapitulation of murine thymopoiesis in vitro from single hematopoietic stem cells

Project description:We report a serum-free, 3-D murine artificial thymic organoid (ATO) system that mimics normal murine thymopoiesis from four different mouse strains with the production of all T cell populations, from early thymic progenitors to functional single positive (CD8SP and CD4SP) TCRaband TCRyd cells. RNA sequencing aligned ATO-derived populations with phenotypically identical primary thymocytes. ATOs initiated with Rag1-/- marrow produced the same differentiation block as seen in the endogenous thymus, and Notch signaling patterns in ATOs mirrored primary thymopoiesis. ATOs initiated with defined hematopoietic stem cells (HSCs) and progenitors from marrow and thymus recapitulated subsequent stages and the normal kinetics of T cell differentiation. Remarkably, a single HSC deposited into ATOs generated a complete trajectory of T cell differentiation producing a similar diverse TCR repertoire across clones. ATOs represent a technically simple, highly reproducible and powerful experimental platform for the study of clonal thymopoiesis from HSCs.

Analysis of transcriptomic profile of iNKT cells

Project description:The maintenance of tissue homeostasis is critically dependent on the function of tissue-resident lymphocytes, including lipid-reactive invariant natural killer T (iNKT) cells. iNKT cells have unique properties according to their tissues of residency, but if and how the tissue environment shapes their antigen specificity remains unknown. By analysing iNKT cells from tissues of mice and humans we demonstrate that their T cell receptor (TCR) repertoire is highly diverse and is distinct for iNKT cells resident in individual tissues resulting in differential lipid-antigen recognition. Within peripheral tissues, the TCR repertoire of iNKT cell recent thymic emigrants is different from that of mature cells, indicating that the iNKT population is shaped after their arrival to the tissues. Accordingly, in homeostatic conditions the repertoire of iNKT cells is modulated by tissue-specific signals that control iNKT cell activation and proliferation resulting in differential clonal expansion found for cells resident in various organs. Moreover, the iNKT cell TCR repertoire changes in response to lipid immunization and is shaped by age and by environmental changes. Thus, post-thymic modification of the iNKT cell TCR repertoire underpins the distinct antigen specificity of iNKT cells residing in peripheral tissues
