在定向迁移之前,嗜酸性粒细胞在细胞因子如IL-5或eotaxin的作用下变得极化。极化发生在f -肌动蛋白组装之前,但调节这些事件的机制以及形状变化如何影响细胞从外周血向肺的迁移尚不清楚。在这项研究中,我们发现脯氨酸异构酶Pin1是il -5诱导的Eos极化和迁移所必需的。免疫共沉淀和免疫荧光分析显示,Pin1与Rho GTPase家族成员直接相互作用。缺乏Pin1的小鼠嗜酸性粒细胞或用Pin1抑制剂处理的人细胞显示il -5诱导的GTPase活性和cofilin磷酸化显著降低,导致F-actin聚合、细胞极化和向趋化因子的定向迁移减少。我们的研究结果表明,Pin1通过调节Rho GTPase活性来调节细胞骨架重组、嗜酸性粒细胞形态和细胞迁移。靶向Pin1和GTPases可以提供一种新的方法来减少哮喘加重期间肺Eos的积累。
Eosinophils become polarized in response to cytokines such IL-5 or eotaxin prior to directional migration. Polarization is preceded by F-actin assembly, but the mechanisms that regulate these events and how the shape change influences cell migration from the peripheral blood into the lung remain unclear. In this study, we show that the prolyl isomerase, Pin1, is required for IL-5-induced Eos polarization and migration. Co-immunoprecipitation and immunofluorescence analysis revealed that Pin1 directly interacts with members of Rho GTPase family. Mouse eosinophils lacking Pin1 or human cells treated with Pin1 inhibitors showed significantly reduced IL-5-induced GTPase activity and cofilin phosphorylation, resulting in reduced F-actin polymerization, cell polarization, and directional migration to chemokines. Our result suggests that Pin1 regulates cytoskeletal re-organization, eosinophil morphology, and cell migration through the modulation of Rho GTPase activity. Targeting Pin1 along with GTPases could provide a new approach to reduce pulmonary Eos accumulation during asthmatic exacerbations.
