(Submitter supplied) In immune responses, activated T cells migrate to B cell follicles and develop to T follicular helper (Tfh) cells, a new subset of CD4+ T cells specialized in providing help to B lymphocytes in the induction of germinal centers 1-3. Although Bcl6 has been shown to be essential in Tfh cell function, it may not regulate the initial migration of T cells 4 or the induction of Tfh program as exampled by CXCR5 upregulation 5. more...

(Submitter supplied) CD4+ T follicular helper cells (TFH) are critical for the formation and function of B cell responses to infection or immunization, but also play an important role in autoimmunity. The factors that contribute to the differentiation of this helper cell subset are incompletely understood, although several cytokines including IL-6, IL-21 and IL-12 can promote TFH cell formation. Yet, none of these factors, nor their downstream cognate STATs, have emerged as non-redundant, essential drivers of TFH cells. more...

(Submitter supplied) Follicular helper T (Tfh) cells promote germinal center (GC) B cell survival and proliferation, and guide their differentiation and Ig isotype switching by delivering contact-dependent and soluble factors, including IL-21, IL-4, IL-9, and IFN-g. IL-21 and IFN-g are co-expressed by Tfh cells during acute and chronic infections, but transcriptional regulation of these cytokines in the GC is incompletely understood. more...

(Submitter supplied) 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. more...

(Submitter supplied) The maintenance of the TFH phenotype depends on continuous signals via ICOS. For a global assessment of differences in gene expression after interruption of the ICOS pathway a genome wide transcriptome analysis was performed. We used the OT-II adoptive transfer system to isolate antigen-specific TFH cells (day 6 after immunization) after short-term (6 hours) blockade of the ICOS pathway using a monoclonal antibody against ICOS-L.

(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) 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...

(Submitter supplied) 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.

(Submitter supplied) Follicular T helper cells (Tfh) provide critical help to B cells for germinal center (GC) formation. Mutations affecting SLAM-associated Protein (SAP) prevent GC formation due to defective T-B cell interactions, yet effects on Tfh cell differentiation remain unclear. We describe the in vitro differentiation of functionally-competent “Tfh-like” cells that expressed Interleukin-21, Tfh markers, and Bcl6, and rescued GC formation in SAP-deficient hosts better than other T helper (Th) cells. more...

(Submitter supplied) T follicular helper (TFH) cells are a distinct type of CD4 T cells that are essential for most antibody and B lymphocyte responses. TFH regulation and dysregulation is involved in a range of diseases. Bcl6 is the lineage defining transcription factor of TFH cells and its activity is essential for TFH cell differentiation and function. However, how Bcl6 controls TFH biology has largely remained unclear, at least in part due to intrinsic challenges of connecting repressors to gene upregulation in complex cell types with multiple possible differentiation fates. more...
