项目摘要
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.
IL-33最近被克隆为ST2的配体。与IL-1β或IL-18一样,IL-33是IL-1细胞因子家族的成员。 IL-33的效果取决于ST2结合,其信号通过MyD88翻译,就像IL-1β或IL-18一样。我们通过挑战BALB/C小鼠反复反复研究了IL-33在直接类型的皮肤接触超敏反应中的作用。野生型BALB/C小鼠或ST2缺陷小鼠对剃光皮肤的敏感性用DNFB敏感,并且每周左耳在左耳中反复挑战DNFB。在每次挑战之前和之后测量耳朵厚度。反应是特异性的。野生型BALB/C小鼠既表现出直接的和延迟型反应,而ST2 KO小鼠没有立即反应。这些结果表明,IL-33在立即接触过敏的机制中可能具有重要作用。
