这项研究表明,E3 泛素连接酶自分泌运动因子受体 (AMFR) 通过促进肺泡巨噬细胞衍生的 GM-CSF 产生来驱动哮喘肺部炎症,并可能成为哮喘治疗的新的潜在药物靶点。肺泡巨噬细胞 (AM) 是专门的组织驻留巨噬细胞,可协调过敏性炎症和哮喘中的免疫反应。然而,什么信号指示 AM 与其他免疫细胞进行交互仍不清楚。在这里,我们报告自分泌运动因子受体(AMFR),一种内质网驻留的 E3 泛素连接酶,在哮喘 AM 中表达上调,并且对于这种情况至关重要。 AMFR 缺乏显着减少过敏诱导的辅助 T 2 (Th2) 和嗜酸性粒细胞炎症,并减少 AM 中粒细胞-巨噬细胞集落刺激因子 (GM-CSF) 的产生。从机制上讲,在胸腺基质淋巴细胞生成素(TSLP)刺激后,AMFR直接与细胞因子诱导的含SH2蛋白(CIS)相关,诱导CIS的Lys48连接的多泛素化泛素化,从而阻断CIS对AMs中信号转导和转录激活剂5(STAT5)磷酸化和下游通路激活的抑制作用。总之,我们的结果表明,AMFR 通过调节 AM 功能在促进哮喘炎症中发挥着至关重要的作用,并可能成为哮喘治疗的新的潜在药物靶点。
This study demonstrates that E3 ubiquitin ligase autocrine motility factor receptor (AMFR) drives lung inflammation in asthma through promoting alveolar macrophage–derived GM-CSF production, and may emerge as a new potential drug target for asthma therapy. Alveolar macrophages (AMs) are specialized tissue-resident macrophages that orchestrate the immune response in allergic inflammation and asthma. However, what signals direct AMs to cross talk with other immune cells remains unclear. Here, we report that autocrine motility factor receptor (AMFR), an endoplasmic reticulum–resident E3 ubiquitin ligase, is upregulated in AMs of asthma and is critical for this condition. AMFR deficiency significantly decreased allergy-induced T helper 2 (Th2) and eosinophilic inflammation, with less granulocyte-macrophage colony-stimulating factor (GM-CSF) production in AMs. Mechanistically, following thymic stromal lymphopoietin (TSLP) stimulation, AMFR associated directly with cytokine-inducible SH2-containing protein (CIS), induced the ubiquitination of Lys48-linked polyubiquitination of CIS, and consequently blocked the inhibitory effect of CIS on signal transducer and activator of transcription 5 (STAT5) phosphorylation and the downstream pathway activation in AMs. In conclusion, our results demonstrate that AMFR serves a crucial role in promoting inflammation in asthma through regulating AM function, and may emerge as a new potential drug target for asthma therapy.
