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

ABSTRACT: 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.

Characterization of lung tissue-resident helper T cells

Project description:To identify the characters of tissue resident CD4 T cells following influenza virus infection, we sorted lung CD45iv-CD4+CD44hi T cells from influenza PR8 infected mice (28 d.p.i.). Then the cells were performed single cell RNA sequencing. At the result, we found clera 5 differnt clusters and each cluster represent different helper T cell types including TH1, TH17 and Treg. One cluster exhibited both tissue residency and TFH cell features. So, we identify the characters of this hybrid lung CD4 T cells.

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.

Chromatin Landscape of IL-4-expressing CD4 T cells in the lung and lung-draining lymph nodes

Project description:Using bulk-, single cell-, ATAC-, and TCR repertoire sequencing, this study reveals that helminth infection causes the expansion of distinct IL-4-competent CD4+ T cells in the lung and lung-draining lymphoid tissues, providing insight into tissue-specific mechanisms of type-2 cytokine regulation and the lineage commitment of T-helper 2 (Th2) and T follicular helper (Tfh) cells. IL-4 competent CD4+ T cells were stratified into three groups: lymphoid-restricted T follicular helper (Tfh) cells; nonlymphoid resident T-helper 2 (Th2) cells; and transitional cells that share identity with both tissue compartments. Differences in transcriptome, locus accessibility, and the enrichment of distinct transcription factor motifs suggested that IL-4 competency was likely achieved via distinct mechanisms among lymphoid- and lung-resident CD4+IL-4+ populations. These findings reveal a complex relationship between lymphoid- and nonlymphoid-resident CD4+ T cell populations in settings of type-2 immunity.

Peripheral blood T helper cells circulate with pathogenic tissue resident T helper cells in chronic GVHD

Project description:Chronic graft versus host disease (cGVHD) is a systemic autoimmune-like syndrome. The role of Tph cells in the pathogenesis of cGVHD has not been examined, although previous studies have shown that cGVHD is characterized by loss of Tfh cells. Here, we show that in cGVHD patients and in a murine model that reflects characteristic features of human cGVHD, the proportions of Tph cells among CD4+ T cells in the blood were expanded. These cells augmented memory B cell differentiation and production of IgG via IL-21. Adoptive transfer experiments showed recirculation between Tph in the blood and tissue-resident T helper (Trh) cells in GVHD target tissues. The TCR repertoires of blood Tph cells and Trh cells in GVHD target tissues of mice were highly overlapping.

Expression Data from in vivo Tfh vs GC Tfh vs 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 polyclonal GC Tfh vs Tfh vs Non-Tfh eight days after LCMV viral infection. Analysis of in vivo follicular helper CD4 T cells (CXCR5high GL7low), versus germinal center follicular helper CD4 T cells (CXCR5hi GL7hi), versus non-follicular helper CD4 T cells (CXCR5low) eight days after viral infection.

Transcription profiling of IL-4-expressing CD4 T cells in the lung and lung-draining lymph nodes

Project description:Using single cell RNA-sequencing and whole-genome targeted transcription profiling, this study reveals that helminth infection causes the expansion of distinct but clonally related IL-4-competent CD4+ T cells in the lung and lung-draining lymphoid tissues providing insight into tissue-specific mechanisms of type-2 cytokine regulation and the lineage commitment of T-helper 2 (Th2) and T follicular helper (Tfh) cells.

Transcriptional analysis of human tonsil Tfh cells

Project description:Follicular helper CD4 T (Tfh) cells provide B cells with signals that are important for the generation of high-affinity Abs and immunological memory and, therefore, are critical for the protective immunity elicited by most human vaccines. In this study we sought to define the gene expression signature of bona fide GC Tfh and Tfh cells. The CD4+ T cell subsets CD45RO+CXCR5-, CD45RO+CXCR5int (Tfh cells), and CD45RO+CXCR5hi (GC Tfh cells) were isolated from 6 tonsil samples for gene expression analysis.

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.
