BET bromodomain inhibition suppresses TH17-mediated pathology.

ABSTRACT: Interleukin (IL) 17-producing T helper (T(H)17) cells have been selected through evolution for their ability to control fungal and bacterial infections. It is also firmly established that their aberrant generation and activation results in autoimmune conditions. Using a characterized potent and selective small molecule inhibitor, we show that the bromodomain and extra-terminal domain (BET) family of chromatin adaptors plays fundamental and selective roles in human and murine T(H)17 differentiation from naive CD4(+) T cells, as well as in the activation of previously differentiated T(H)17 cells. We provide evidence that BET controls T(H)17 differentiation in a bromodomain-dependent manner through a mechanism that includes the direct regulation of multiple effector T(H)17-associated cytokine
