Reversing SKI–SMAD4-mediated suppression is essential for TH17 cell differentiation
TGFβ signalling regulates T helper 17 (TH17) cell differentiation by reversing SKI–SMAD4-mediated suppression of RORγt, revealing a potential therapeutic target for treating TH17-related diseases.

A helping hand against autoimmunity
The TH17 helper cells of the immune system have a dark side: they mediate autoimmune disorders. Two drugs that prevent the differentiation and activity of these cells might be of therapeutic value. See Letters p.486 & p.491

Generation of pathogenic TH17 cells in the absence of TGF-β signalling
CD4+ T cells that selectively produce interleukin (IL)-17 (TH17 cells) are essential for host defence and autoimmunity. It has been thought that IL-6 and transforming growth factor (TGF)-β1 are the factors responsible for initiating the specification of TH17 cells. Here, however, it is shown that TH17 differentiation can occur in the absence of TGF-β signalling. IL-6, IL-23 and IL-1β effectively induced IL-17 production in naive precursors. These data reveal an alternative mode for TH17 differentiation and the importance of IL-23.

IκBζ regulates TH17 development by cooperating with ROR nuclear receptors
Interleukin-17-producing helper T (TH17) cells are a distinct T-cell subset characterized by its role in autoimmune disease. Here it is shown that the development of TH17 cells requires the transcription factor IκBζ, as well as nuclear receptors of the ROR family. Mice lacking IκBζ have a defect in TH17 development and are resistant to the induction of experimental autoimmune encephalomyelitis. The study points to some new potential molecular targets for drugs to treat autoimmune disease.
