Sci Rep:IL-33、IL-25和TSLP能够导致真菌相关的蛋白酶诱导的先天性气道炎症的发展

2018-12-31 AlexYang MedSci原创

某种来源于屋尘螨和植物的蛋白酶能够通过干扰上皮细胞之间的紧密联系激活过敏性气道炎症的起始。蛋白酶(比如屋尘螨来源的Der p1和/或木瓜来源的木瓜蛋白酶)的吸入能够引起野生型小鼠和Rag缺陷小鼠(缺乏获得性免疫细胞,比如T、B和NKT细胞)中气道嗜酸性粒细胞过多症。相反,考虑到来源于环境中无处不在的曲霉属真菌(真菌相关的蛋白酶;FAP),其对过敏性气道嗜酸性粒细胞过多产生的影响仍旧所知甚少。最近,

某种来源于屋尘螨和植物的蛋白酶能够通过干扰上皮细胞之间的紧密联系激活过敏性气道炎症的起始。蛋白酶(比如屋尘螨来源的Der p1和/或木瓜来源的木瓜蛋白酶)的吸入能够引起野生型小鼠和Rag缺陷小鼠(缺乏获得性免疫细胞,比如T、B和NKT细胞)中气道嗜酸性粒细胞过多症。相反,考虑到来源于环境中无处不在的曲霉属真菌(真菌相关的蛋白酶;FAP),其对过敏性气道嗜酸性粒细胞过多产生的影响仍旧所知甚少。

最近,有研究人员发现,野生型小鼠对FAP的吸入能够导致气道嗜酸性粒细胞过多症,并且依赖于蛋白酶激活的受体2(PAR2),而不是TLR2和TLR4。这些发现表明了FAP蛋白酶活性,而不是FAP的内毒素活性,在引起症状中是重要的。另外,嗜酸性粒细胞过多症的发展还可以被先天性免疫细胞(ILCs)(比如先天性淋巴细胞),而不是获得性免疫细胞,比如T、B和NKT细胞调控。研究人员还指出,虽然IL-33、IL-25和胸腺基质淋巴细胞生成素(TSLP)参与了FAP诱导的ILC调节的气道嗜酸性粒细胞过多症,IL-33,而不是IL-25和/或TSLP,对嗜酸性粒细胞过多症是非常关键的。

最后,研究人员指出,他们的发现提高了人们对FAP诱导的气道炎症分子机制认识。

Redox Biol:自噬调节慢性IL-13刺激期间气道上皮细胞中的DUOX1定位和超氧化物产生。

气道上皮是与外界环境广泛接触的界面,因此需要精细的协调响应能力以适当的调节炎症。经典地,自噬是响应外部细胞应激的一种稳态调节通路,并且在慢性气道疾病中自噬水平升高。

罗氟司特可减小哮喘患者过敏原诱导的气道炎症反应据最新的一项研究表明,不同剂量的罗氟司特可减小哮喘患者过敏原诱导的气道炎症反应。“研究表明,对于轻至中度哮喘患者,罗氟司特并无急性支气管扩张作用,”Philip Bardin博士写道,“该发现并不意外,因为罗氟司特是一种抗炎药物而并非直接的支气管扩张剂。但是,罗氟司特在变态原激发试验中的抗炎作用却是十分显著的。”Bardin及其同事回顾了1997-20

Clin Exp Allergy:重度哮喘患者对口服泼尼松龙的反应与皮质类固醇程度有关!

由此可见,疾病严重程度并不影响全身性皮质类固醇治疗的反应。因此,这项研究并不支持重度哮喘与皮质类固醇抵抗相关的概念。只有基础嗜酸性粒细胞炎症与皮质类固醇的生理反应相关,其证实了在指导皮质类固醇治疗上测量嗜酸性粒细胞炎症的重要性。
