Project description:CD4+ memory T cells play a pivatol role in mediating long-term immunity and therefore are an important target in vaccine development. Multiple functionally distinct helper CD4+ T cell subsets can arise in response to a single invading pathogen, complicating the identification of rare memory CD4+ T cells. Here we found that expression of Id3, an inhibitor of E protein transcription factors, identified a population of cells within both the CD4+ Tfh and Th1 helper lineages that exhibited memory potential in response to secondary infection. Notably, a subset of Th1 memory cells expressing Id3 exhibited enhanced expansion upon response to pathogen, generating both Th1 and Tfh secondary effector cell populations, and displayed enrichment of key molecules associated with memory potential when compared to Id3lo Th1 cells. Thus, Id3 expression serves as an important marker of multipotent memory CD4+ T cells.

Project description:Comparison of transcriptome between early Tfh vs. early Th1 cells Blimp-1-YFP LCMV gp specific TCRtg Smarta cells were transferred into B6 mice, which were then infected with LCMV Armstrong. On day 3 after infection, splenocytes were stained to sort Blimp-1-YFP+IL-2Ra+ Th1 cells or Blimp-1-YFP-IL-2Ra- Tfh cells for RNAseq analysis. Contributor: LIAI RNAi center (LIAI)

Project description:ATAC-Seq experiments were performed to elucidate the chromatin state changes among naïve CD4+ T cells, WT follicular helper T (TFH) cells and WT type 1 helper T (TH1) cells Day2 (D2), Day5 (D5), Day8 (D8) post-LCMV-Armstrong infection, as well as EZH2-null (KO) TFH and TH1 at Day8 post-LCMV-infection. The analysis suggested stringent lineage-specific mode of chromatin accessibility in each group, indicating chromatin remodeling is tightly associated with TFH versus TH1 lineage differentiation in response to acute viral infection. Furthermore, the comparison between wild-type and EZH2-null TFH cells showed that less-opening state of certain chromatin accessible region in TFH-differentiation associated genes in the formers, suggesting EZH2 led to permissive chromatin accessibility primarily at specific regions of TFH-associated genes. H3K27me3-ChIP-seq was performed in WT TFH and TH1 cells to confirm the deposition of the histone marks at those loci.

Project description:We did microarray experiments to elucidate the transcriptome changes due to TCF-1 deficiency in Tfh cells. These data clearly demonstrate that Tfh-associated genes were down-regulated in TCF-1-null Tfh cells, whereas Th1-associated signatures were up-regulated, indicating that TCF-1 initiates the Tfh fate by directly strengthening Tfh signatures while suppressing Th1-associated genes. We first sorted WT and TCF-1-null Tfh cells (2 samples per group, each sample was pooled from 4 mice) at day 8 after LCMV Armstrong infection. Then, we extracted RNA, which were subsequently sent to microarray analysis.

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).

Project description:Microarray experiments were performed to demonstrate the transcriptome changes due to Rictor deficiency in memory follicular T helper (Tfh) and Type 1 T helper (Th1) cells. These data revealed that the immunological memory formation and persistance associated genes are changed in Rictor-null memory Tfh and Th1 cells, indicating that Rictor is essential for memory CD4 T cell pool.
