T cell receptors repertoire sequencing of the human CD8+ naive subsets (CXCR3-,CXCR3+)

Project description:The presented data corresponds to the analysis of two discrete subsets of human CD8+ naive T cells, defined by positive and negative expression of the chemokine receptor CXCR3 (TNR3-, TNR3+). In this study we demonstrated that these subsets have different potential to generate fully-differentiated effector T cells following antigen-specific stimulation. The performed systematic immune repertoire analysis (T cell receptor beta chain (TRB)) of the sorted cell subsets revealed diverse physico-chemical properties of TRB CDR3 sequences suggesting enhanced TCR self-reactivity in human TNR3+ cells. In total, we analyzed 74 samples (from 11 patients, 3 replicates of each cell subset (excluding one missing replicate) and additionally for 3 patients CD8+ memory T cells in 3 replicates). We used the Human TCR Profiling Kit (MiLaboratory LLC) for sequencing libraries preparation and Illumina NextSeq 550 sequencing (150+150bp) followed by the demultiplexing procedure using MIGEC software (https://github.com/mikessh/migec).

RNA-seq of human peripheral blood B helper T-cell subsets

Project description:Human T-cells that express CXCR5 and/or CCR6 provide help to naive B-cells for IgG production. To understand the molecular pathways that are shared or unique to individual B helper T-cell subsets in human peripheral blood, CD4+IL-7R+CD25-/lo helper T-cells were purified according to the expression of CXCR5, CCR6, CXCR3, CD161 and CCR5 as follows: 1) TFH17(CD161-): CXCR5+CXCR6+CXCR3-CD161- 2) Th17: CXCR5-CCR6+CXCR3-, CD161+ or CCR5+ 3) CCR6”SP”: CXCR5-CCR6+CXCR3-CD161-CCR5- RNA-seq was performed with FACS-purified T-cell subsets from 3 healthy individuals.

RNA-seq bulk of CCR6+Th-cell subsets in Crohn’s Disease, peripheral blood and intestinal lamina propria

Project description:This RNA seq experiment was designed to identify a gene signature of a CCR5-expressing subset of human intestinal Th17-cells. T helper-cells from peripheral blood of healthy donors and from the lamina propria of Crohn’s Disease patients were FACS-purified according to the expression of the chemokine receptors CCR6, CCR5 and CXCR3. Four CCR6+Th- subsets were isolated according to CXCR3 and CCR5 expression: two CXCR3- Th17 subsets (CCR5-: “cTh17” or CCR5+: “pTh17”) and two subsets of CXCR3+ Th1/17-cells (CCR5+ or CCR5-)

CXCR3+ Treg cells suppress Th1-immune responses through expression of the co-inhibitory receptors CD85k and Lag-3

Project description:CD4+Foxp3+ Treg cells are essential for maintaining self-tolerance and preventing excessive immune responses. In the context of Th1 immune responses, co-expression of the Th1 transcription factor T-bet with Foxp3 is essential for Treg cells to control Th1 responses. T-bet-dependent expression of CXCR3 directs Tregs to the site of inflammation, however, the suppressive mediators enabling effective control of Th1 responses at this site are unknown. In this study, we determined the signature of CXCR3+ Treg cells arising in Th1 settings and defined universal features of Treg cells in this context using multiple Th1-dominated models. Our analysis defined a set of Th1-specific co-inhibitory receptors that are specifically expressed in Treg cells during Th1 immune responses. Among these, we identified the novel co-inhibitory receptor CD85k as a functional mediator of the enhanced suppression of Th1 effector cells by CXCR3+ Treg cells.

Transcriptional profiles of CCR7lo effector memory human T cell subsets

Project description:The aim of this study was to identify differentially-expressed genes in CCR4hi/CXCR3- and CCR4lo CXCR3+ CCR6+ human Th17 cell subsets Human CD45RO+ memory T cells isolated from the peripheral blood of healthy adult donors were sorted into 4 predominant CCR7lo CD25- effector memory subsets: (1) Th1 - CCR6- CCR4lo CXCR3+; (2) Th2 - CCR6- CCR4hi CXCR3+; (3) Th17 - CCR6+ CCR4hi CXCR3-; (4) Th17.1 - CCR6+ CCR4lo CXCR3-. Sorted cells were cultured in media and activated via anti-CD3/anti-CD28 beads for 36 hours. All subsets were then harvested and used for RNA extraction and microarray experiments. Th1 vs Th2; Th1 vs Th17; Th1 vs Th17.1; Th2 vs Th17; Th2 vs Th17.1; Th17 vs Th17.1

Antibody repertoire sequencing of human tonsillar B cell subsets

Project description:In response to antigen challenge, human B cells clonally expand, undergo selection and differentiate within secondary lymphoid tissues to produce mature B cell subsets and high affinity antibodies necessary for an effective immune response. However, the interplay between affinity, antibody class and different B cell fates has proved challenging to decipher in primary human tissue. We have applied an integrated analysis of bulk and single-cell antibody repertoires paired with single-cell transcriptomics of human B cells from a model secondary lymphoid tissue. Specifically, here we have performed bulk B cell repertoire sequencing of the immunoglobulin heavy chain (IgH) for sorted B cell subsets from paediatric tonsil tissue. Matched single-cell gene expression and single-cell VDJ data are also available for the same patient donors.

Pro-inflammatory Beta Cell Small Extracellular Vesicles Induce Beta Cell Failure Through Activation of the CXCL10/CXCR3 Axis in Diabetes

Project description:Coordinated communication among pancreatic islet cells is necessary for the maintenance of glucose homeostasis. In diabetes, chronic exposure to pro-inflammatory cytokines has been shown to perturb β-cell communication and function. Compelling evidence has implicated extracellular vesicles (EVs) in modulating physiological and pathological responses to β-cell stress. We report that pro-inflammatory β-cell small EVs (cytoEV) induce β-cell dysfunction, promote a pro-inflammatory islet transcriptome, and enhance recruitment of CD8+ T-cells and macrophages. Proteomic analysis of cytoEV revealed an enrichment of the chemokine, CXCL10, with surface topological analysis depicting CXCL10 as membrane-bound on cytoEV to facilitate direct binding to CXCR3 receptors on the surface of β-cells. CXCR3 receptor inhibition reduced CXCL10-cytoEV binding and attenuated β-cell dysfunction, inflammatory gene expression, and leukocyte recruitment to islets. Collectively, this work implicates the significant role of pro-inflammatory β-cell derived small EVs in modulating β-cell function, global gene expression, and antigen presentation through activation of the CXCL10/CXCR3 axis.
