CXCR3+ T cells in Multiple Sclerosis Correlate with Reduced Diversity of the Gut Microbiome

ABSTRACT: - Patients with MS exhibited decreased alpha diversity in the composition of their gut bacteria compared to healthy controls - Circulating lymphocytes from MS patients were enriched for Th1 (CXCR3+) and Th1-17 (CXCR3+ CCR6+) memory CD4+ cells and for CXCR5+ memory CD4+ cells - A higher proportion of CXCR3+ T-cells from MS patients co-expressed the gut homing receptor α4β7 compared to healthy controls Reduced alpha diversity correlated significantly with expression of CXCR3+ on CD8+ T-cells and CXCR5— memory T-cells.

Transcriptional analysis of human blood CXCR5+ CD4 T cell populations

Project description:The vast majority of currently licensed human vaccines work on the basis of long-term protective antibody responses. Generation of long term humoral immunity is a complex process predominantly dependent on germinal centers and CD4 T cell help to B cells. Follicular helper T cells (Tfh) are the specialized CD4 T cells for B cell help. However, whether such cells develop memory in humans and can be tracked in human blood has been enigmatic. We identified a subpopulation of blood CXCR5+ PD-1+CXCR3- resting CD4 T cells that are most related to Tfh cells of lymphoid tissue by gene expression profile and phenotype. Functional analysis showed that these memory Tfh cells were specialized for helping B cells. Moreover, these cells correlate with a clinically important outcome: development of potent neutralizing antibodies against HIV in HIV+ individuals. CD4 T cells were enriched from fresh blood of 5 normal donors by magnetic beads negative selection. Following enrichment, CD14-CD16-CD19-CD8-CD4+CD45RA- cells from each donor were FACS sorted into the following 5 populations: CXCR5-, CXCR5+PD1+CXCR3-, CXCR5+PD1+CXCR3+, CXCR5+PD1-CXCR3-, and CXCR5+PD1-CXCR3+. The gene expression profile of each cell population was determined.

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.

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

Expression data from virus-specific mouse Th1 and Tfh CD4 T cell subsets after LCMV infection

Project description:CD4 T follicular helper (Tfh) cells provide the required signals to B cells for germinal center reactions that are necessary for longlived antibody responses. However, it remains unclear whether there are CD4+ memory T cells committed to the Tfh lineage after antigen clearance. Using adoptive transfer of antigen-specific memory CD4+ subpopulations (based on CXCR5 and Ly6c expression)in the LCMV infection model, we found that there are distinct memory CD4+ T cell populations with commitment to the Tfh and Th1 lineages. Our conclusions are based on gene expression profiles, epigenetic studies and phenotypic and functional analysis. The gene expression profiles of virus-specific CD4 T cell subets at effector and memory stages is presented here. The SMARTA TCR transgenic / adptive transfer system was used to identify and sort subsets of antigen-specific CD4 T cells (based on their expression of Ly6c and CXCR5) elicited after acute infection with LCMV (Arm).

Human peripheral blood CD4+ T cell subsets

Project description:Cells were isolated from healthy human donors (n=2). Unstimulated cells. Cells were stained with CD4, CD45RA, CCR7 and CXCR7. Using flow cytometry, 4 CD4+ T cell populations were sorted: (1) Naïve (CD45RA+CCR7+CXCR5-), (2) Central memory (CD45RA-CCR7+CXCR5-), (3) Effector memory (CD45RA-CCR7-CXCR5-) and (4) CXCR5+ cells (CD45RA-CCR7-CXCR5+) RNA were extracted from sorted cells and hybridized on Affymetix HU133Plus2 chips. Each population were repeated on different donors such that n=2.

Circulating CXCR5+CXCR3+PD-1Lo Tfh-like cells in HIV-1 controllers with neutralizing antibody breadth

Project description:HIV-1-specific broadly-neutralizing antibodies (bnAb) typically develop in individuals with continuous high-level viral replication and increased immune activation, conditions that cannot be reproduced during prophylactic immunization. Understanding mechanisms supporting bnAb development in the absence of high-level viremia may be important for designing bnAb-inducing immunogens. Here, we show that the breadth of neutralizing antibody responses in HIV-1 controllers was associated with a relative enrichment of circulating CXCR5+ CXCR3+ PD-1Lo CD4 T cells. These CXCR3+ PD-1Lo Tfh-like cells were preferentially induced in vitro by functionally superior dendritic cells from controller neutralizers, and able to secrete IL-21 and support B cells. In addition, these CXCR3+ PD-1Lo Tfh-like cells contain higher proportions of stem cell-like memory T cells, and upon antigenic stimulation differentiated into PD-1Hi Tfh-like cells in a Notch-dependent manner. Together, these data suggest that CXCR5+ CXCR3+ PD-1Lo cells represent a dendritic cell-primed precursor cell population for PD-1Hi Tfh-like cells that may contribute to the generation of bnAbs in the absence of high–level viremia.

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.
