T 辅助细胞 2 细胞因子,包括白细胞介素 (IL)-4、IL-5 和 IL-13,在过敏性哮喘中发挥着关键作用。这些细胞因子通过 Janus 激酶/信号转导器和转录激活剂 (STAT) 以及 Ras 细胞外信号调节激酶 (ERK) 信号通路传递信号。尽管细胞因子信号传导抑制蛋白(SOCS)家族蛋白已被证明可以调节STAT通路,但调节ERK通路的机制尚未阐明。 Sprouty 相关的 Ena/VASP 同源 1 结构域蛋白 (Spred)-1 最近被确定为生长因子介导的、Ras 依赖性 ERK 激活的负调节因子。在这里,我们使用 Spred-1 缺陷小鼠,证明 Spred-1 负向调节过敏原诱导的气道嗜酸性粒细胞增多和高反应性,而不影响辅助 T 细胞分化。生化检测表明 Spred-1 抑制 IL-5 依赖性细胞增殖和 ERK 激活。这些数据表明 Spred-1 通过调节过敏性哮喘中的 IL-5 信号传导来负向控制嗜酸性粒细胞的数量和功能。
T helper 2 cytokines, including interleukin (IL)-4, IL-5, and IL-13, play a critical role in allergic asthma. These cytokines transmit signals through the Janus kinase/signal transducer and activator of transcription (STAT) and the Ras–extracellular signal-regulated kinase (ERK) signaling pathways. Although the suppressor of cytokine signaling (SOCS) family proteins have been shown to regulate the STAT pathway, the mechanism regulating the ERK pathway has not been clarified. The Sprouty-related Ena/VASP homology 1–domain-containing protein (Spred)-1 has recently been identified as a negative regulator of growth factor–mediated, Ras-dependent ERK activation. Here, using Spred-1–deficient mice, we demonstrated that Spred-1 negatively regulates allergen-induced airway eosinophilia and hyperresponsiveness, without affecting helper T cell differentiation. Biochemical assays indicate that Spred-1 suppresses IL-5–dependent cell proliferation and ERK activation. These data indicate that Spred-1 negatively controls eosinophil numbers and functions by modulating IL-5 signaling in allergic asthma.
