|
Bcl6 middle domain repressor function is required for T follicular helper cell differentiation and utilizes the corepressor MTA3.
|
2 |
26460037
|
Mimicked acetylation of the Bcl6 middle domain (K379Q) in CD4 T cells results in significant reductions in Tfh differentiation in vivo.
|
3 |
26460037
|
Although Bcl6 K379Q still bound to the Prdm1 cis-regulatory elements in Tfh cells, Prdm1 expression was derepressed.
|
4 |
26460037
|
This was a result of the failure of Bcl6 K379Q to recruit metastasis-associated protein 3 (MTA3).
|
5 |
26460037
|
The loss of Bcl6 function in Bcl6 K379Q-expressing CD4 T cells could be partially rescued by abrogating Prdm1 expression.
|
6 |
26460037
|
In addition to Prdm1, we found that Bcl6 recruits MTA3 to multiple genes involved in Tfh cell biology, including genes important for cell migration, cell survival, and alternative differentiation pathways.

|
Thus, Bcl6 middle domain mediated repression is a major mechanism of action by which Bcl6 controls CD4 T-cell fate and function.
