摘要
IL-22 是在工作对感染支持纸巾的天生的免疫的 IL-10 家庭的新奇 cytokine。尽管 CD4+ 助手 T 淋巴细胞(TH ) 作为 IL-22 的来源被发现，这 cytokine 的规定糟糕被理解。这里，我们证明 IL-22 被也做 IL-17 的 TH 房间的一个新奇子集在 mRNA 和蛋白质层次表示。IL-22 和 IL-17 被发现被即时 PCR 以及 ELISA 分析被 TGFbeta 和 IL-6 并列地在 TH 区别期间调整。然而， IL-22 不调整 TH 区别；外长的 IL-22 或一个 IL-22 对手没在 TH 区别上有效果。这些数据表明 IL-17-producing T 房间表示的新奇 cytokine，并且建议在组织发炎和自体免疫的疾病表明小径的 IL-22 和 IL-17 的相互作用和协同作用。
IL-22 is a novel cytokine in the IL-10 family that functions to promote innate immunity of tissues against infection. Although CD4＋ helper T lymphocytes （TH） were found as a source of IL-22, the regulation of this cytokine has been poorly understood. Here, we show that IL-22 is expressed at both mRNA and protein levels by a novel subset of TH cells that also makes IL-17. IL-22 and IL-17 were found to be coordinately regulated by TGFI3 and IL-6 during TH differentiation by real-time PCR as well as ELISA analysis. However, IL-22 does not regulate TH differentiation; exogenous IL-22 or an IL-22 antagonist had no effect on TH differentiation. These data demonstrate a novel cytokine expressed by IL-17-producing T cells, and suggest interaction and synergy of IL-22 and IL-l 7 signaling pathways in tissue inflammation and autoimmune diseases.
