Maturation of high-affinity B lymphocytes is precisely controlled during the germinal center reaction. This is dependent on CD4(+)CXCR5(+) follicular helper T cells (TFH) and inhibited by CD4(+)CXCR5(+)Foxp3(+) follicular regulatory T cells (TFR). Because NFAT2 was found to be highly expressed and activated in follicular T cells, we addressed its function herein. Unexpectedly, ablation of NFAT2 in T cells caused an augmented GC reaction upon immunization. Consistently, however, TFR cells were cl ...[more]

Expression Data from WT and Sh2d1a-/- in vivo follicular helper CD4 T cells (TFH) versus non follicular helper CD4 T cells (non-TFH)

Project description:CD4 T cell help is critical for both the generation and maintenance of germinal centers, and T follicular helper (TFH) cells are the CD4 T cell subset required for this process. SAP (SH2D1A) expression in CD4 T cells is essential for germinal center development. However, SAP-deficient mice have only a moderate defect in TFH differentiation as defined by common TFH surface markers. CXCR5+ TFH cells are found within the germinal center as well as along the boundary regions of T/B cell zones. Here we show that germinal center associated T cells (GC TFH) can be identified by their co-expression of CXCR5 and the GL7 epitope, allowing for phenotypic and functional analysis of TFH and GC TFH populations. Here we show GC TFH are a functionally discrete subset of further polarized TFH cells, with enhanced B cell help capacity and a specialized ability to produce IL-4 in a TH2-independent manner. Strikingly, SAP-deficient mice have an absence of the GC TFH subset and SAP- TFH are defective in IL-4 and IL-21 production. We further demonstrate that SLAM (Slamf1, CD150), a surface receptor that utilizes SAP signaling, is specifically required for IL-4 production by GC TFH. GC TFH cells require IL-4 and IL-21 production for optimal help to B cells. These data illustrate complexities of SAP-dependent SLAM family receptor signaling, revealing a prominent role for SLAM receptor ligation in IL-4 production by germinal center CD4 T cells but not in TFH and GC TFH differentiation. Analysis of in vivo antigen-specific (LCMV-specific, SMARTA TCR transgenic) WT and Sh2d1a-/- follicular helper CD4 T cells (CXCR5high),versus non-follicular helper CD4 T cells (CXCR5low), eight days after viral infection.

Quantitative Analysis of Global Proteome and Lysine Acetylome for Human CD4+ T Follicular Helper Cells

Project description:Follicular helper T (Tfh) are a subset of CD4+ T helper cells that provide help to germinal center B cells and mediate the development of long-lived humoral immunity. Tfh cells dysregulation is associated with several major autoimmune diseases. Although recent studies showed Tfh cells differentiation is controlled by the transcription factor Bcl6, cytokines and cell-cell signals, limited information is available on the proteome and post-translational modifications (PTM) of proteins in human Tfh cells. In this study, using TMT labeling technique, antibody-based affinity enrichment and high-resolution LC-MS/MS analysis, we investigated quantitative proteome and acetylome in human naive CD4+ T cells and in vitro induced Tfh (iTfh) cells. In total, we identified 802 up-regulated proteins and 598 down-regulated proteins at the threshold of 1.5 folds in iTfh cells compared to naive CD4+ T cells. With the aid of intensive bioinformatics, biological process, cellular compartment, molecular function, KEGG pathway and protein-protein interaction of these differentially expressed proteins were revealed. Moreover, our acetylome data showed that 22 lysine acetylated proteins are up-regulated and 26 lysine acetylated proteins are down-regulated in iTfh cells compared to the naive CD4+ T cells, among which 11 differentially acetylated lysine residues in core histone were identified, indicating proteins acetylation and epigenetic mechanism are involved in regulating Tfh cells differentiation. These data provide a significant resource for studies of Tfh differentiation and normal and perturbed Tfh cell function.

Gene expression of primary human T Follicular Helper (TFH) cells and naive CD4-positive helper T cells from tonsils of healthy volunteers

Project description:In this experiment we generated Affymetrix gene expression data for T Follicular Helper (TFH) cells from tonsils of healthy volunteers (4 biological replicates) and naive CD4-positive helper T cells (2 biological replicates). TFH cells provide a model relevant to SLE as TFH operate upstream of the activation of pathogenic autoantibody-producing B cells during the disease. This experiment accompanies promoter capture-C and ATAC-seq experiments on the same cell types.

Bcl6 and Blimp-1 are reciprocal and antagonistic regulators of follicular helper CD4 T cell differentiation). Experiment Overall Design: Analysis of in vivo antigen-specific (LCMV-specific, SMARTA TCR transgenic) follicular helper CD4 T cells (CXCR5high), versus non-follicular helper CD4 T cells (CXCR5low), eight days after viral infection.

Germinal center T follicular helper cell IL-4 production is dependent on SLAM receptor (CD150)

RNAseq of follicular helper T cell from Elp3 deficient mice after Complete Freund Adjuvant immunisation

Project description:Loss of Elp3 in CD4 T cells hindered the development of an optimal T follicular helper T cell (TFH) response. To understand the molecular pathway by which Elp3 is necessary for TFH responses, mice deficient for Elp3 in T cells and WT littermate were immunized with ovalbumin emulsified with complete Freund Adjuvant. 8 days later, TFH were sorted from the draining lymph nodes and submitted for RNAseq

Transcriptional profiling for lung tissue-resident helper T cell and spleen follicular T cells

Project description:We reported hybrid CD4+ T cell population following influenza viru infection. The hybrid CD4+ T cells exhibit both tissue residency and follicular helper T cell features. To further charaterization, we sorted lung tissue-resident helper T (TRH or TTH) cells (CD45iv-CD4+CD44+GITR-PD1hiFR4hi), non-TRH (CD45iv-CD4+CD44+GITR-PD1lowFR4low), spleen follicalar helper T (TFH) cells (CD4+CD44+GITR-PD1hiCXCR5hi) and non-TFH cells (CD4+CD44+GITR-PD1lowCXCR5low). Then the cells were applied for RNA sequencing. At the resut, we showed tissue-residency related genes are highly enriched in lung TRH but not spleen TFH cells. And The lung TRH cells express higher levels of TFH-related genes than lung-non TRH cells. Therefore, we suggest TRH cells play a role as tissue-resident helper T cells.

ATAC-seq of primary human T Follicular Helper (TFH) cells and naive CD4-positive helper T cells from tonsils of healthy volunteers

Project description:Genome Wide Association Studies (GWAS) have been successful in yielding >60 loci for Systemic Lupus Erythematosus (SLE). However, it is known that GWAS just reports genomic signals and not necessarily the precise localization of culprit genes, with eQTL efforts only able to infer causality to a minority of such loci. Thus, we sought to carry out physical and direct ‘variant to gene mapping’ by integrating results from high-throughput chromatin conformation capture and ATAC-seq assays. This experiment refers to the ATAC-seq part of our work. To determine informative proxy SNPs for each of the SLE GWAS sentinel loci, we generated ATAC-seq open chromatin maps for primary human T Follicular Helper (TFH) cells from tonsils of healthy volunteers (3 biological replicates), a model relevant to SLE as TFH operate upstream of the activation of pathogenic autoantibody-producing B cells during the disease. We also generated open chromatin maps for naive CD4-positive helper T cells (3 biological replicates).
