RORγt-specific transcriptional interactomic inhibition suppresses autoimmunity associated with TH17 cells.

ABSTRACT: The nuclear hormone receptor retinoic acid-related orphan receptor gamma t (RORγt) is a transcription factor (TF) specific to TH17 cells that produce interleukin (IL)-17 and have been implicated in a wide range of autoimmunity. Here, we developed a novel therapeutic strategy to modulate the functions of RORγt using cell-transducible form of transcription modulation domain of RORγt (tRORγt-TMD), which can be delivered effectively into the nucleus of cells and into the central nerve system (CNS). tRORγt-TMD specifically inhibited TH17-related cytokines induced by RORγt, thereby suppressing the differentiation of naïve T cells into TH17, but not into TH1, TH2, or Treg cells. tRORγt-TMD injected into experimental autoimmune encephalomyelitis (EAE) animal model can be delivered effectively in t
