An excess of interleukin 17 (IL-17) may contribute to chronic inflammatory disorders, but mechanisms that regulate IL-17 in immune cells are unclear. Here we report that tristetraprolin (TTP) inhibits IL-17 production in human T cell lines. Overexpression of TTP decreased the expression of IL-17. Conversely, TTP inhibition by siRNA increased IL-17 production. IL-17 mRNA contains eight AREs within its 3′UTR. TTP bound directly to the IL-17 mRNA 3′UTR at a location between the fourth and seventh AREs and enhanced decay of IL-17 transcripts. These results suggest that TTP could control IL-17-mediated inflammation.
► Overexpression of TTP inhibits IL-17 production in human T cells. ► TTP binds to the ARE within the IL-17 3′UTR. ► TTP enhances the decay of IL-17 mRNA. ► TTP can be a novel target to control IL-17 production.
