白细胞介素(IL)-5和IL-13被认为在哮喘的发病机制中起关键作用。尽管两种细胞因子都使用嗜酸性粒细胞趋化因子来调节嗜酸性粒细胞增多症,但认为IL-13与IL-5通过单独的途径来诱导过敏性肺中的气道高反应性(AHR)。然而,抗IL-5或抗IL-13治疗未能完全抑制肺组织中嗜酸性粒细胞的积累,这混淆了IL-5和IL-13在疾病过程中使用的关键途径的鉴定。通过使用缺乏IL-5和嗜酸性粒细胞趋化因子(IL-5/eotaxin-/-)的小鼠,我们已经消除了组织嗜酸性粒细胞增多症和过敏性肺中AHR的诱导。值得注意的是,在缺乏IL-5/嗜酸细胞活化趋化因子的小鼠中,CD 4 + T辅助细胞(Th)2淋巴细胞产生IL-13(气道平滑肌收缩和阻塞的关键调节剂)的能力显著受损。此外,嗜酸性粒细胞转移到IL-5/eotaxin−/−小鼠克服了T细胞IL-13产生的内在缺陷。因此,由嗜酸性粒细胞产生的因子可以直接或间接地调节Th 2细胞发育期间IL-13的产生。我们的数据表明,IL-5和嗜酸性粒细胞趋化因子内在地调节IL-13从Th 2细胞的生产,这些信号系统不一定是独立的效应途径,也可以整合到调节过敏性疾病的各个方面。
Interleukin (IL)-5 and IL-13 are thought to play key roles in the pathogenesis of asthma. Although both cytokines use eotaxin to regulate eosinophilia, IL-13 is thought to operate a separate pathway to IL-5 to induce airways hyperreactivity (AHR) in the allergic lung. However, identification of the key pathway(s) used by IL-5 and IL-13 in the disease process is confounded by the failure of anti–IL-5 or anti–IL-13 treatments to completely inhibit the accumulation of eosinophils in lung tissue. By using mice deficient in both IL-5 and eotaxin (IL-5/eotaxin−/−) we have abolished tissue eosinophilia and the induction of AHR in the allergic lung. Notably, in mice deficient in IL-5/eotaxin the ability of CD4+ T helper cell (Th)2 lymphocytes to produce IL-13, a critical regulator of airways smooth muscle constriction and obstruction, was significantly impaired. Moreover, the transfer of eosinophils to IL-5/eotaxin−/− mice overcame the intrinsic defect in T cell IL-13 production. Thus, factors produced by eosinophils may either directly or indirectly modulate the production of IL-13 during Th2 cell development. Our data show that IL-5 and eotaxin intrinsically modulate IL-13 production from Th2 cells and that these signaling systems are not necessarily independent effector pathways and may also be integrated to regulate aspects of allergic disease.
