In vitro activation of Btnl-1 transduced MODE-K cells with different stimuli

ABSTRACT: The experiment was designed to assess how intestinal epithelial cells respond to different soluble factors produced by intraepithelial lymphocytes (IEL) and how this response is altered when the epithelial cells express Btnl1. Total RNA of MODE-K cells transduced with Btnl1-GFP or GFP alone and stimulated with TNF+IL-1_ in comparison to medium and with supernatant from anti-CD3-activated IEL in comparison to supernatant from unstimulated IEL

Comprehensive proteomics analyses of IL-15 driven activation of intestinal intraepithelial lymphocytes

Project description:Intestinal intraepithelial lymphocytes (IEL) are an abundant population of tissue-resident T cells that protect the gut from pathogens and maintain intestinal homeostasis. The cytokine IL-15 is trans-presented by epithelial cells to IEL in complex with the IL-15 receptor α chain (IL-15Rα) and plays essential roles both in maintaining IEL homeostasis, and in inducing IEL activation in response to epithelial stress. When overproduced, IL-15 is a key driver of the gluten-induced enteropathy Coeliac disease, through cytotoxic activation of IEL. To better understand how IL-15 directly regulates both homeostatic and inflammatory functions of IEL, we performed quantitative proteomics of IL-15/Rα-stimulated murine IEL, sorted into their 3 main subpopulations, TCRγδ CD8αα, TCRαβ CD8αβ and TCRαβ CD8αα expressing IEL. The data reveal that high IL-15/Rα stimulation licenses cell cycle activation, upregulates the biosynthetic machinery in IEL, increases mitochondrial respiratory capacity and induces expression of cell surface immune receptors and adhesion proteins that potentially drive IEL activation.

Expression data from mouse small intestinal γδ intraepithelial lymphocytes

Project description:The mammalian gastrointestinal tract harbors thousands of bacterial species that include symbionts as well as potential pathogens. The immune responses that limit access of these bacteria to underlying tissue remain poorly defined. In this study, we used microarrays to uncover the transcriptional responses that occur in small intestinal γδ intraepithelial lymphocytes following bacterial challenge. γδ intraepithelial lymphocytes (γδ IEL) were isolated by flow cytometry from the small intestines of germ-free mice, or from age- and sex-matched conventionally-raised counterparts. We extracted RNAs from these purified γδ IEL for analysis on Affymetrix DNA microarrays. The mice were all >8 weeks in age, and each sample represents a pool of RNAs from 5-8 mice.

Gene expression analysis of CD122HI versus CD122LO VÎ³7+ murine small intestinal IEL at 14-17 days of age

Project description:Background: Recently have found that Btnl1 expressed by murine enterocytes shapes the local TCR-VÎ³7+ compartment by driving their clonotypic expansion and phenotypic maturation from CD122LO to CD122HI VÎ³7+ cells. The neonatal (D14-17) murine small intestinal epithelium is enriched for VÎ³7+ IEL displaying an â??immatureâ?? CD122LO cell surface phenotype. We believe these cells are precursors for CD122HI VÎ³7+ IEL. Method: To further characterise this putative product-progenitor relationship, CD122hi Vg7+ and CD122lo Vg7+ IEL were purified from individual D14-D17 mice on four independent occasions and compared by total RNAseq. Conclusion: >3000 genes are differentially expressed between CD122HI and CD122LO murine Vg7+ neonatal IEL 4 independent Paired samples of CD122hi Vg7+ and CD122lo Vg7+ IEL were purified from the small intestinal epithelium of pooled 14-17 day old mice. RNA was isolated from sorted samples. Gene expression analysis was performed by total RNAseq.

Gene expression of conventional and unconventional T cell subsets

Focused examination of the intestinal lamina propria yields greater molecular insight into mechanisms underlying SIV induced immune dysfunction

Project description:In this study three Indian rhesus macaques were infected with Simian Immunodeficiency Virus (SIVmac251). This generates a chronic infection mirroring AIDS in the animals. Prior to infection (day 0) and at two different time-points post-infection (day 21 and day 90), intestinal resection biopsies were performed. The intestinal tissue was then separated into different sub-sections including lamina-propria lymphocytes (LPL), intra-epithelial lymphocytes (IEL), stroma or matrix and epithelium. In this study we report the genome-wide transcriptional response at the two different time-points, specific to LPL, relative to pre-infection samples. For this purpose we have used the Affymetrix Rhesus Macaque GeneChip. 3 Rhesus Macaques prior to infection and 21 and 90 days of infection

Tissue adaptation is the dominant driver of the proteomic landscape of intestinal intraepithelial lymphocytes

Project description:Intestinal intraepithelial T lymphocytes (T-IEL) patrol the single layer of epithelial cells lining the gut, and consist of both induced T-IEL, derived from systemic antigen-experienced lymphocytes, and natural IEL, that are developmentally targeted to the intestine. To gain functional insights into these enigmatic cells, we used high-resolution quantitative mass spectrometry to investigate the proteomic landscape of the main T-IEL populations in the gut. Comparing the proteomes of induced T-IEL, tissue-resident memory TCRαβ+ CD8αβ+ cells and natural TCRγδ+ CD8αα+ and TCRαβ+ CD8αα+ T-IEL, with naive CD8+ T cells from lymph nodes reveals striking similarities between T-IEL subsets and the dominant effect of the gut environment on T-IEL phenotypes. Analysis of copy numbers/cell of >7000 proteins provides new understanding of the differences in composition of T cell antigen receptor signal transduction pathways in T-IEL versus conventional T cells and reveals skewing of the metabolic machinery towards an exhausted T cell phenotype adapted to the intestinal environment. This study provides a resource for exploring and understanding how multiple inputs are integrated into T-IEL function.

Intestinal epithelial and intraepithelial T cell crosstalk mediates a dynamic response to infection

Project description:Oral infection of mice with Salmonella Typhimurium leads to rapid changes in small intestinal TCRgd IEL behavior. How these changes are induced is currently unknown. By analyzing the transcriptome of TCRgd and intestinal epithelial cells in the steady state and after infection, we find a potential role for epithelial cell MYD88 expression in regulating the IEL response. By additionally analyzing the transcriptome of epithelial cell-specific, conditional Myd88 knockout animals after Salmonella infection, we address the role of epithelial cell Myd88 signaling in regulating the IEL and EC response to Salmonella infection.

Human intestinal T cell and paired blood transcriptomes

Project description:The intestinal mucosa harbors the largest accumulation of T lymphocytes in the body. While these T cells play an important role in immune homeostasis, they are also implicated in triggering and maintaining pathological intestinal inflammation. In humans they are poorly characterised, and even mouse transcriptomes have been reported for only a few individual cell types, many of which lack direct human equivalents. Using expression microarrays on T cells isolated from ileal biopsies and in silico analysis, we present here an unbiased, transcriptome-wide view of function in T cell subpopulations of the healthy human intestine and delineate signalling pathways that are distinct from those seen in peripheral blood T cells. Paired blood and intestinal biopsies from 6 age/sex matched healthy human subjects. Intestinal biopsies processed to release intraepithelial lymphocytes (IEL) and lamina propria lymphocytes (LPL). All samples then used to generate T effector memory (Tem) cells of CD4+ and CD8+ subsets by flow sorting. 6 individuals; 3 cell sources per individual (blood, LPL, IEL); 2 Tem subsets per cell source (CD4+ and CD8+). 36 arrays in total

Novel type of EATL evolving from mucosal M-NM-3M-NM-4-T-cells in a RCD type I patient

Project description:Enteropathy associated T-cell lymphoma (EATL) is a rare non-Hodgkin lymphoma that may complicate celiac disease and typically occurs in patients with refractoriness to the gluten- free diet. The majority of these patients harbor intra-epithelial lymphocytes (IEL) with an aberrant phenotype in the small intestine which are thus considered as the M-bM-^@M-^XprecursorM-bM-^@M-^Y lymphoma cells. We here report on a case of extra-intestinal EATL that originated from a clonal M-NM-3M-NM-4-IEL population rather than from aberrant IEL. This EATL displayed a distinctive pattern of immunophenotypical, T-cell receptor immunogenetic, and chromosomal aberrancies defining this lymphoma as a novel variant of EATL. sample vs reference
