Interleukin (IL)-23 and CD4+ T helper-17 (Th17) cells are thought to be critical in the development of psoriasis. Here, we report that IL-23 predominantly stimulated dermal γδT cells to produce IL-17 that led to disease progression. Dermal γδT cells constitutively expressed the IL-23 receptor (IL-23R), RORγt, and various chemokine receptors. IL-17 production from dermal γδT cells was independent of αβT cells. The epidermal hyperplasia and inflammation induced by IL-23 were significantly decreased in T cell receptor δ deficient (Tcrd−/−) and IL-17 receptor deficient (Il17ra−/−) mice but occurred normally in Tcra−/− mice. Imiquimod-induced skin pathology was also significantly decreased in Tcrd−/− mice. Perhaps further promoting disease progression, IL-23 stimulated dermal γδT cell expansion. In psoriasis patients, γδT cells were also greatly increased in affected skin and produced large amounts of IL-17. Thus, IL-23-responsive dermal γδ T cells are the major IL-17 producers in the skin and may represent a novel target for the treatment of psoriasis.
