Interleukin (IL) 25 (IL-17E), a distinct member of the IL-17 cytokine family, plays important roles in evoking T helper type 2 (Th2) cell-mediated inflammation that features the infiltrations of eosinophils and Th2 memory cells. However, the cellular sources, target cells, and underlying mechanisms remain elusive in humans. We demonstrate that human Th2(More)
The molecular mechanisms underlying the initiation of innate and adaptive proallergic type 2 responses are not understood. Interleukin (IL) 25, a member of the IL-17 cytokine family, was recently reported (Owyang, A.M., C. Zaph, E.H. Wilson, K.J. Guild, T. McClanahan, H.R. Miller, D.J. Cua, M. Goldschmidt, C.A. Hunter, R.A. Kastelein, and D. Artis. 2006. J.(More)
The physiological regulation of the expression of interleukin (IL)-9, a cytokine traditionally regarded as being T(H)2 associated, remains unclear. Here, we show that IL-9-expressing T cells generated in vitro in the presence of transforming growth factor-beta and IL-4 express high levels of mRNA for IL-17 receptor B (IL-17RB), the receptor for IL-25.(More)
How naive CD4(+) T cells commit to the T helper type 2 (T(H)2) lineage is poorly understood. Here we show that the basic helix-loop-helix transcription factor Dec2 was selectively expressed in T(H)2 cells. CD4(+) T cells from Dec2-deficient mice showed defective T(H)2 differentiation in vitro and in vivo in an asthma model and in response to challenge with(More)
Allergic diseases, including asthma, are characterized by T helper type 2 (Th2) cell-mediated inflammations, coupled with tissue infiltration by eosinophils. In this study, we demonstrate that multiple protease allergens, including papain and DerP1, efficiently induce interleukin (IL)-25 and thymic stromal lymphopoietin (TSLP) gene expression, and this(More)
