我们发现肿瘤坏死因子受体超家族25(TNFRSF25)/TNFSF15对是过敏性肺部炎症的关键触发因素,而过敏性肺部炎症是哮喘的主要特征。TNFRSF25(TNFR25)信号是在Th2极化的CD4细胞中发挥辅助性T细胞2(Th2)效应功能所必需的信号,并共同刺激神经节苷脂激活的NKT细胞产生IL-13。在体内,作为TNFR25配体的抗体阻断TNFSF15(TL1A)可以抑制肺部炎症和Th2细胞因子(如IL-13)的产生,即使在呼吸道抗原暴露后几天给药也是如此。同样,通过显性负性转基因(DN)阻断TNFR25,使小鼠对肺部炎症具有抵抗力。过继转移野生型NKT细胞后,过继转移NKT细胞会使NKT缺陷小鼠变得敏感,但在转移DNTNFR25转基因NKT细胞后不会。TNFR25/TL1A对似乎为肺内Th2细胞因子的产生提供了早期信号,因此可能是试图减轻哮喘患者肺部炎症的药物靶点。
We identify the tumor necrosis factor receptor superfamily 25 (TNFRSF25)/TNFSF15 pair as critical trigger for allergic lung inflammation, which is a cardinal feature of asthma. TNFRSF25 (TNFR25) signals are required to exert T helper cell 2 (Th2) effector function in Th2-polarized CD4 cells and co-stimulate interleukin (IL)-13 production by glycosphingolipid-activated NKT cells. In vivo, antibody blockade of TNFSF15 (TL1A), which is the ligand for TNFR25, inhibits lung inflammation and production of Th2 cytokines such as IL-13, even when administered days after airway antigen exposure. Similarly, blockade of TNFR25 by a dominant-negative (DN) transgene, DN TNFR25, confers resistance to lung inflammation in mice. Allergic lung inflammation–resistant, NKT-deficient mice become susceptible upon adoptive transfer of wild-type NKT cells, but not after transfer of DN TNFR25 transgenic NKT cells. The TNFR25/TL1A pair appears to provide an early signal for Th2 cytokine production in the lung, and therefore may be a drug target in attempts to attenuate lung inflammation in asthmatics.
