(Submitter supplied) 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. more...

(Submitter supplied) TFH and Th1 cells generated after viral or intracellular bacterial infections are critical for the control of infections and the development of immunological memories. However, the mechanisms that govern the choice of activated CD4 T cells to the two alternative fates remain unclear. Here, we found that reciprocal expression of TCF1 and Blimp1 between viral-specific TFH and Th1 cells started early after infection. more...

(Submitter supplied) Epigenetic changes, including histone methylation, control T cell differentiation and memory formation, though the enzymes that mediate these processes are not clear. We show that UTX, a histone H3 lysine 27 (H3K27) demethylase, promotes the generation of T follicular helper (Tfh) cells, a CD4+ T cell subset essential for B cell antibody generation and clearance of chronic viral infections. Mice with T cell specific UTX deletion (UTX TKO mice) had fewer Tfh cells, showed defective germinal center formation, lacked virus-specific IgG production, and were unable to resolve chronic lymphocytic choriomeningitis virus infection. more...

(Submitter supplied) 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. more...

(Submitter supplied) CD4 T cells responses induced by LM61 immunization are heterogeneous in phenotype. The majority consists of Th1 cells, but there is also a consistent population of Tfh-differentiated cells and a minor population of Treg cells. Tfh-differentiated cells, alongside Th1 cells expand upon LCMV challenge.

(Submitter supplied) 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. more...

(Submitter supplied) Microarray experiments were performed to elucidate the transcriptome changes due to EZH2 deficiency in follicular T helper (TFH) cells. These data suggest TFH-lineage associated genes are down-regulated in EZH2-null TFH cells, indicating that EZH2 primes TFH differentiation by regulating canonical genes of TFH cells.

(Submitter supplied) Following viral clearance, antigen-specific CD4+ T cells contract and form a pool of distinct Th1 and Tfh memory cells that possess unique epigenetic programs, allowing them to rapidly recall their specific effector functions upon rechallenge. DNA methylation programing mediated by the methylcytosine dioxygenase Tet2 contributes to balancing Th1 and Tfh cell differentiation during acute viral infection, however the role of Tet2 in CD4+ T cell memory formation and recall is unclear. more...

(Submitter supplied) Cytotoxic CD4 T lymphocytes (CD4-CTL) are important in anti-viral immunity.  For example, we have previously shown that in mice, CD4-CTL are important to control ectromelia virus (ECTV) infection.  How viral infections induce CD4-CTL responses remains incompletely understood. Here we demonstrate that not only ECTV but also vaccinia virus and Lymphocytic Choriomeningitis virus induce CD4-CTL, but that the response to ECTV is stronger.  Using ECTV, we also demonstrate that in contrast to CD8-CTL, CD4-CTL differentiation requires constant virus replication and ceases once the virus is controlled.  We also show that Major Histocompatibility Complex Class II molecules on CD11c+ cells are required for CD4-CTL differentiation and for mousepox resistance.  Transcriptional analysis indicated that anti-viral CD4-CTL and non-cytolytic T Helper 1 (Th1) CD4 T cells have similar transcriptional profiles, suggesting that CD4-CTL are terminally differentiated classical Th1 cells.  Interestingly, CD4-CTL and classical Th1 cells expressed similar mRNA levels of the transcription factors ThPOK and GATA-3, necessary for CD4 T cell linage commitment; and Runx3, required for CD8 T cell development and effector function.  However, at the protein level, CD4-CTL had higher levels of the three transcription factors suggesting that further post-transcriptional regulation is required for CD4-CTL differentiation.  Finally, using CRISPR-Cas9 deletion of Runx3 in CD4 T cells, we demonstrate that the development of CD4-CTL but not of classical Th1 CD4 T cells requires Runx3 following ECTV infection.  These results further our understanding of the mechanisms of CD4-CTL differentiation during viral infection and the role of post-transcriptionally regulated Runx3 in this process.

(Submitter supplied) In mice chronically infected with lymphocytic choriomeningitis virus (LCMV), we defined a subset of exhausted CD8+ T cells abundantly expressing chemokine receptor CXCR5. These CXCR5+ CD8+ T cells were preferentially localized in B cell follicles, expressing less inhibitory receptors while exhibiting more potent cytolytic activity compared to the CXCR5- subset. Furthermore, we identified Id2-E2A axis as the regulator for the generation of this subset. more...

(Submitter supplied) Follicular helper T cells (TFH), known as the primary helpers of the germinal center (GC) reaction, promote the humoral immune response to defend against various pathogens. Under conditions of infection by different types of pathogens, many shared transcription factors (TFs), such as Bcl-6, TCF-1 and Maf, are broadly expressed in TFH cells, orchesting TFH cell differentiation and function. In addtion, TFH cells also coexpress environmentally specific TFs as their conventional T cell counterparts (such as T-bet, GATA-3 or ROR-γt, which are expressed in Th1, Th2 or Th17 cells, respectively). more...
