| Research Abstract |
IL-33 has been cloned recently as the ligand of ST2. As with IL-1β or IL-18, IL-33 is a member of the IL-1 cytokine family. Effect of IL-33 is dependent on ST2 binding, and its signal is transduced via MyD88, as with IL-1β or IL-18. We examined the role of IL-33 in an immediate type contact hypersensitivity of skin by challenging BALB/c mice with DNFB repeatedly. Wild-type BALB/c mice or ST2-deficient mice were sensitized on shaved back skin with DNFB, and repeatedly challenged with DNFB on the left ear once a week. The ear thickness was measured before and after each challenge. The reactions were hapten specific. Wild-type BALB/c mice showed both immediate and delayed-type reactions, whereas ST2 KO mice did not show any immediate reaction. These results suggest that IL-33 may have an important role in the mechanism of immediate contact hypersensitivity.
