(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 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) In this study, we sought to distinguish phenotypically and functionally distinct virus-specific effector CD4 T cell subsets that form during acute lymphocytic choriomeningitis virus (LCMV) infection and to examine their ability to develop into memory T cells. To further characterize the effector subsets and identify genetic pathways and transcription factors involved in their differentiation, we performed genome-wide gene expression profiling of the three day 8 effector cell populations: (1) PSGL1hi Ly6Chi, (2) PSGL1hi Ly6Clo and (3) PSGL1lo Ly6Clo Smarta CD4 T cells along with (4) day 60 memory PSGL1hi and (5) naïve Smarta CD4 T cells using Illumina BeadChips. 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) During an immune response, CD8 T cells fall along a gradient of memory potential, but the regulators of these fate decsisions are not well understood. We utlized Id3-GFP and Id2-YFP reporter mice to elucidate the role of Id3 and Id2 during early CD8 T cell differentiation by gene expression.

(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) Follicular helper T (Tfh) cells comprise an important subset of helper T cells; however, their relationship with other helper lineages is incompletely understood. Herein, we show IL-12 acting via signal transducer and activator of transcription 4 (STAT4) induced both Il21 and Bcl6 genes, generating cells with features of both Tfh and Th1 cells. However, STAT4 also induced T-bet. Using ChIP-seq, we defined the genome-wide targets of T-bet and found that it repressed Bcl6 and other markers of Tfh cells, thereby attenuating the nascent Tfh-like phenotype in the late phase of Th1 specification. 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) Foxp3+ regulatory T (TR) cells are phenotypically and functionally diverse, and broadly distributed in lymphoid and non-lymphoid tissues. However, the pathways guiding the differentiation of tissue-resident TR populations have not been well defined. By regulating E-protein function, Id3 controls the differentiation of CD8+ effector T cells and is essential for TR maintenance and function. We show that dynamic expression of Id3 helps define three distinct mouse TR populations, Id3+CD62LhiCD44lo central (c)TR, Id3+CD62LloCD44hi effector (e)TR and Id3- eTR. more...

(Submitter supplied) Trascriptional analysis of CD2 hi and CD25 lo CD4+ effector T cells during acute viral infection. SMARTA cells were transferred into B6 mice, followed by infection with LCMV. At day 5 post-infection, CD25 hi and CD25 lo SMARTA cells were isolated from the spleen by FACS. Consistent with our prior studies showing that CD25 lo early effector cells give rise to both Tfh effector cells and memory T cells, we observed gene expression in the CD25 lo population consistent with Tfh differentiation. more...

(Submitter supplied) Upon activation, specific CD4+ T cells up-regulate the expression of CD11a and CD49d, surrogate markers of pathogen-specific CD4+ T cells. However, using T-cell receptor transgenic mice specific for a Plasmodium antigen, termed PbT-II, we found that activated CD4+ T cells develop not only to CD11ahiCD49dhi cells, but also to CD11ahiCD49dlo cells during acute Plasmodium infection. CD49dhi PbT-II cells, localized in the red pulp of spleens, expressed transcription factor T-bet and produced IFN-γ, indicating that they were type 1 helper T (Th1)-type cells. more...

(Submitter supplied) It is now well established that the E- and Id-protein axis regulates multiple steps in lymphocyte development. However, it remains unknown as to how E- and Id-proteins mechanistically enforce and maintain the naïve T cell fate. Here we show that Id2 and Id3 suppressed the development and expansion of innate-variant TFH cells. Innate-variant TFH cells required MHC Class I-like signalling and were associated with germinal center B cell development. more...
