Project description:Extensive cellular heterogeneity exists within specific immune-cell subtypes classified as a single lineage, but its molecular underpinnings are rarely characterized at a genomic scale. Here, we use single-cell RNA-seq to investigate the molecular mechanisms governing heterogeneity and pathogenicity of Th17 cells isolated from the central nervous system (CNS) and lymph nodes (LN) at the peak of autoimmune encephalomyelitis (EAE) or polarized in vitro under either pathogenic or non-pathogenic differentiation conditions. Computational analysis reveals a spectrum of cellular states in vivo, including a self-renewal state, Th1-like effector/memory states and a dysfunctional/senescent state. Relating these states to in vitro differentiated Th17 cells, unveils genes governing pathogenicity and disease susceptibility. Using knockout mice, we validate four novel genes: Gpr65, Plzp, Toso and Cd5l (in a companion paper). Cellular heterogeneity thus informs Th17 function in autoimmunity, and can identify targets for selective suppression of pathogenic Th17 cells while sparing non-pathogenic tissue-protective ones.

Project description:The intestinal immune system must elicit robust immunity against harmful pathogens but restrain immune responses directed against commensal microbes and dietary antigens. The mechanisms that maintain this dichotomy are poorly understood. Here we describe a population of CD11b+F4/80+CD11câ?? macrophages in the lamina propria (LP) that express several anti-inflammatory molecules including interleukin 10 (IL-10), but little or no pro-inflammatory cytokines, even upon stimulation with Toll-like receptor (TLR) ligands. These macrophages induced, in a manner dependent on IL-10, retinoic acid and exogenous transforming growth factor-β, differentiation of FoxP3+ regulatory T cells. In contrast, LP CD11b+ dendritic cells elicited IL-17 production. This IL-17 production was suppressed by LP macrophages, indicating that a dynamic interplay between these subsets may influence the balance between immune activation and tolerance. Splenic or small intestine lamina propria CD11b+11c- cells were isolated for RNA extraction and hybridization on Affymetrix microarrays. We sought to determine the unique genetic profile of small intestine lamina propria CD11b+11c- cells. Experiment Overall Design: 4 samples analyzed, 2 spleen and 2 intestine

Project description:Purpose: The goals of this study are to compare mRNAs expressed by Th17 cells and ILC3s in small intestine of lamina propria of mice. Methods: Small intestine were digested with collagenase, dispase, and DNase. Percoll enriched lamina propria Th17 and ILCs sorted by BD ARIA II. Total RNA were harvested and sequencing were performe. The sequence reads that passed quality filters were analyzed at the transcript isoform level with two methods: Burrows–Wheeler Aligner (BWA) and TopHat followed by CuffDiff. qRT–PCR validation was performed using SYBR Green assays. Results: Small intestine Th17 cells and ILCs exhibit differential gene expression profiles.

Project description:This study determined the genes that are differentially expressed when regulatory T cells (Tregs) were isolated from the lamina propria of the small and large intestine from mice with impaired IL-2Rβ signaling (designated Y3) or impaired IL-2Rβ signaling and lack of CD103 expression (designated Y3/CD103-/-) when compared to Tregs from WT mice. 204 unique annotated mRNAs were differentially expressed by ≥1.5 fold between these 3 groups (Fig. 6B). Very few mRNAs were uniquely up or down regulated in relationship to impaired IL-2Rβ signaling or the combination of impaired IL-2Rβ signaling and lack of CD103 expression. Thus, lack of CD103 does not obviously regulated signaling in Tregs in the gut mucosa and most differentially expressed genes were due to impaired IL_2Rβ signaling. Gene enrichment analysis of these differentially expressed genes identified 4 major enrichment groups (EG) are: EG1, Cytokine-cytokine receptor interaction and the JAK-STAT signaling pathway; EG2, regulation of lymphocyte activation and proliferation; EG3, regulation of cell death and the caspase pathway in apoptosis; and EG4, transcription. Mouse regulatory T cells (Tregs) cells were FACS purified based on expression of red fluorescent protein linked to the Foxp3 gene. These cells were obtained from the lamina propria of the small and large intestine from WT, Y3, and Y3/CD103-/- mice. Total RNA was prepared and processed to probe Affymetrix mouse Gene ST2.0 arrays.

Project description:Mouse intestinal innate immune cells have been identified as inducing Th17 cell differentiation. However, few studies have investigated innate immune cells that are involved in CD (Crohn's disiease) pathogenesis in humans. The present study aimed to identify a human intestinal lamina propria cell subset that induces Th17 cells, and to clarify its role in CD pathogenesis. Intestinal mucosa samples were obtained from patients who underwent resection of colorectal cancer or CD. Lamina propria cells (LPCs) were obtained by enzymatic digestion, and were analyzed for expression of HLA-DR, lineage markers (Lin), CD14, and CD163 using flow cytometry. Among HLA-DRhigh Lin- cells, we identified a CD14+ CD163low cell subset that was selectively present in intestinal LPCs. We identified CD14+ CD163low cells as having a potent capacity to induce Th17 cell differentiation in human intestinal lamina propria. The Th17-inducing activity of these cells was enhanced in CD patients. The Cy3-labeled cDNAs were hybridized on Agilent-039494 SurePrint G3 Human GE v2 8x60K Microarray (G4845A) in one color experiments, resulting in four individual microarrays.
