(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) T follicular helper (Tfh) cell is a unique T cell subset specialized in promoting germinal center reactions. Bcl6 has been identified as an obligatory transcription factor in Tfh cells; however, the molecular mechanism underlying Bcl6 function still remains unknown. Here, we combined genome-wide Bcl6 occupancy and transcriptome profiling to systemically analyze Bcl6 targets in Tfh cells. We found that Bcl6 exhibits unique binding preferences in Tfh cells from those in Th9, B cells and macrophage and its binding is closely associated with decrease in 5-hydroxymethylcytosine (5hmC). more...

(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) Follicular helper T cell (Tfh) provide essential help for humoral immune response. However, how Tfh differentiation is epigenetically regulated remains incompletely understood. Here we found that H3K36me2 methyltransferase Nsd2 is required for Tfh differentiation. Lack of Nsd2 leads to reduced Tfh generation and germinal center response. Mice with Nsd2 deficiency in T cells have reduced capability of chronic virus control. more...

(Submitter supplied) 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. more...

(Submitter supplied) 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, TCR signaling, 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. 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.

(Submitter supplied) Higher- or lower-affinity GC B cells are directed to plasma cell or recycling GC cell fates; however, how commitment to the plasma cell fate takes place is unclear. By using the level of Bcl6 as a marker, we found that a population of light zone (LZ) GC cells, Bcl6loCD69hi with IRF4 and higher-affinity BCRs or Bcl6hiCD69hi with lower- affinity BCRs, favored the plasma cell or recycling GC cell fate, respectively. more...

(Submitter supplied) T follicular helper (Tfh) cells play a pivotal role in germinal center reactions, which requires Bcl6 transcription factor. To analyze their relationships with other effector T cell lineages and their stability in vivo, we developed and analyzed a new Bcl6 reporter mouse alone or together with other lineage reporter systems. Assisted with genome-wide transcriptome analysis, we show substantial plasticity of T cell differentiation in the early phase of immune response. more...
