RNA-sequencing of BCL6-sufficient and -insufficient OT-II TFH cells

ABSTRACT: We analyzed the transcriptome differences of BCL6-sufficient (CD4-Cre) and -insufficient (CD4-CrexBcl6fl/+) OT-II TFH cells. CD4-CrexBcl6fl/+ or control CD4-Cre OT-II T cells were transferred into CD45.1 Sap-/- mice. At day 3 post NP-OVA immunization, CXCR5hiPD-1hi TFH cells were sort-purified from the draining lymph node and prepared for RNA-seq analysis. Two technical repeats of ~200 cells per sample from each of 3 mice were included. BCL6-insufficient TFH cells differentially expressed many genes; among those downregulated were Stim1 and Plcg1, which code for STIM1 and PLCg1, respectively, that both impinge on calcium signaling downstream of TCR activation. Moreover, KEGG pathway analyses revealed that the calcium signaling-related pathway was generally upregulated in wildtype as compared to BCL6-insufficient TFH cells. These data support the notion that BCL6 control follicular T-B interactions by regulating multiple target genes involved in antigen-triggered calcium signaling in T cells.

Expression data from BCL6-YFP-positive Tfh cells, BCL6-YFP-negative Tfh cells, non-Tfh cells, and naïve helper T cells.

Project description:We found that a number of Tfh cells downmodulated BCL6 protein after their development, and we sought to compare the gene expression between BCL6-hi Tfh cells and BCL6-low Tfh cells. CD4+ T cells were sorted from immunized and non-immunized mice for RNA extraction and hybridization on Affymetrix microarrays. Bcl6yfp/+ OT-II cells were transferred to congenic recipient mice, and immunized with NP-OVA in CFA subcutaneously. Seven or ten days after immunization, cells were collected from draining lymph nodes, and sorted on FACSAria by the expression of CXCR5, PD-1 and BCL6-YFP. Naive CD4+ T cells were CD4+ CD44lo CD62Lhi cells from unimmunized mice.

Foxp1 is a rate-limiting and essential negative regulator of Tfh cell differentiation

Project description:CD4+ T follicular helper (Tfh) cells are essential for germinal center (GC) and high-affinity antibody responses. Yet the regulation that determines the initial development of Tfh cells is still largely unknown. Here we find that transcription factor Foxp1, previously shown to be essential in maintaining T cell quiescence, is a rate-limiting and essential negative regulator of Tfh cell differentiation. NaM-CM-/ve CD4+ T cells constitutively express Foxp1A, and stimulation through the T cell receptor (TCR) transiently induces the expression of a shorter Foxp1D isoform. In T cell-dependent (TD) humoral responses, CD4+ T cells deficient in all Foxp1 isoforms preferentially differentiate into Tfh cells, resulting in substantially increased GC and antibody responses. This negative regulation of Foxp1 on Tfh cell differentiation shows profound dominance: even in the absence of B cells, Foxp1-deficient CD4+ T cells differentiate into Tfh cells with high frequencies and sustained Bcl6 expression. Further, in the absence of Foxp1, Tfh cells are generated in higher frequencies than seen with Bcl6 overexpression and Tfh cell differentiation becomes significantly resistant to Blimp1-mediated repression. Finally, our experiments reveal specific roles of Foxp1A and Foxp1D in inhibiting Tfh cell differentiation: TCR-induced Foxp1D functions as a M-bM-^@M-^XgatekeeperM-bM-^@M-^Y to block the initial Tfh cell development, and together Foxp1A and Foxp1D proteins inversely determine Tfh cell generation in a dosage-dependent manner. Our study suggests that two Foxp1 isoforms provide a M-bM-^@M-^\double checkM-bM-^@M-^] mechanism as fundamental regulators in Tfh cell differentiation and humoral responses.

RNA-sequencing of pre-GC B cells helped by CD4-CrexBcl6fl/+ or CD4-Cre OT-II T cells

Project description:We analyzed transcriptome differences of antigen-specific pre-GC B cells. We transferred wildtype (CD4-Cre) or BCL6-insufficient (CD4-CrexBcl6fl/+) OT-II T cells into SAP-deficient mice and immunized these mice with NP-OVA. By day 3 post immunization, we sort-purified NP-binding B cells that were developing into GCs and conducted RNA-seq analyses of their transcriptome. NP+IgDlowB220+ pre-GC B cells from recipients of the same group were pooled to sort-purify 4 200-cell repeats. Using a gene expression signature induced by CD40 signaling in B cells for enrichment analysis, we found such CD40-induced gene set expression was significantly deprived in those NP-binding B cells helped by CD4-Cre´Bcl6fl/+ T cells. These data suggest BCL6 insufficiency in T cells leads to impaired CD40L signaling to B 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.

BCL6 orchestrates Tfh differentiation via multiple distinct mechanisms

Project description:Tfh cells are required for T cell help to B cells, and BCL6 is the defining transcription factor of Tfh cells. However, the functions of Bcl6 in Tfh have largely remained unclear. Here we defined the BCL6 cistrome in primary human germinal center Tfh cells to assess mechanisms of BCL6 regulation of CD4 T cells, comparing and contrasting BCL6 function in T and B cells. BCL6 primarily acts as a repressor in Tfh cells, and BCL6 binding was associated with control of Tfh cell migration and repression of alternative cell fates. Interestingly, although some BCL6 bound genes possessed BCL6 DNA binding motifs, many BCL6-bound loci were instead characterized by the presence of DNA motifs for AP1 or STAT. AP1 complexes are key positive downstream mediators of TCR signaling and external stimuli. We show that BCL6 can directly bind AP1, and BCL6 depends on AP1 for recruitment to BCL6 binding sites with AP1 motifs, suggesting that BCL6 subverts AP1 activity. These findings reveal that BCL6 has broad and multifaceted effects on Tfh biology, and provide insight into how this master regulator mediates distinct cell-context dependent phenotypes. Sorted naM-CM-/ve tonsil cells were activated with anti-CD3+CD28 Ab coated beads and transduced with BCL6 or control lentiviral vectors as described. RNA was isolated at day 5 following LV infection and microarrays performed as discussed herein. RNA was isolated with the RNeasy Micro Kit (QIAGEN). The quantity and quality of the RNA were confirmed with a NanoDrop 2000c (Thermo Fisher Scientific) and an Experion Electrophoresis System (Bio-Rad). Samples (20 ng) were amplified with Illumina MessageAmp II aRNA Amplification Kits (Ambion), hybridized to HumanHT-12_V4 BeadChips (Illumina), and quantified with Genome Studio (Illumina). Normalized data (heatmap of blood cells) or raw data (heatmap of tonsil cells and Volcano plot) were analyzed with the GenePattern software suite.

Genome binding/occupancy profiling of Tox2 in Tfh-like cells

Project description:T Follicular helper (Tfh) cell is an effector CD4+ T cell subset specialized in helping B cells in germinal centers (GC) reactions. Although Bcl6 was identified as a Tfh-specific transcription factor essential for their development, the molecular mechanisms underlying Bcl6 regulation and Tfh cell commitment remain unclear. Here, we report that Tox2 transcription factor is highly expressed in Tfh cells, regulated by Bcl6 and STAT3. Forced expression of Tox2 drives Bcl6 expression and Tfh development. Mechanistically, Tox2 directly binds to Tfh-associated genes, including Bcl6, and functions to promote their chromatin accessibility and modulate the activities of other Tfh-regulating factors. Conversely, genetic deletion of Tox2 results in defective Tfh differentiation, and inhibiting both Tox and Tox2 in T cells abolishes Tfh differentiation and GC response. Thus, our results demonstrate that Tox2 is a key transcription factor that regulates Bcl6 expression and Tfh development and suggest a Tox2-Bcl6 axis in feed-forward regulation of Tfh program.

Dependence on Bcl6 and Blimp1 identifies distinct mechanisms driving memory and follicular helper CD4+ T cell differentiation [scRNA-Seq]

Project description:During the immune response, CD4+ T cells differentiate into distinct effector subtypes, including follicular helper T (Tfh) cells that help B cells, and into memory cells. Tfh and memory cells are required for long-term immunity; both depend on the transcription factor Bcl6, raising the question of whether they differentiate through similar mechanisms. Here, using notably single-cell RNA and ATAC sequencing, we show that virus-responding CD4+ T cells lacking both Bcl6 and Blimp1 can differentiate into cells with transcriptomic, chromatin accessibility and function attributes of memory cells, but not of Tfh cells. Thus, Bcl6 promotes memory cell differentiation primarily through its repression of Blimp1. These findings demonstrate that distinct mechanisms underpin the differentiation of memory and Tfh CD4+ cell and define the Bcl6-Blimp1 axis as a potential target for promoting long-term memory T cell differentiation.
