Biol Pharm Bull:过敏性鼻炎中T细胞介导的鼻高反应性

2020-01-20 AlexYang MedSci原创

过敏性鼻炎患者承受着各种各样的症状,比如打喷嚏、流鼻涕和鼻塞。随着疾病严重度和慢性进展,鼻高反应性(NHR)能够在这些患者产生和发展。最近,有研究人员在开发一个小鼠过敏性鼻炎模型中,发现了免疫小鼠在进行重复的鼻抗原挑战时能够发展为NHR。通过使用遗传修饰小鼠和一个原始开发的T细胞转移小鼠模型,研究人员确认了NHR中分化为几种辅助细胞后CD4+T细胞的关键作用。从另一方面来讲,免疫球蛋白E/肥大细胞

过敏性鼻炎患者承受着各种各样的症状,比如打喷嚏、流鼻涕和鼻塞。随着疾病严重度和慢性进展,鼻高反应性(NHR)能够在这些患者产生和发展。

最近,有研究人员在开发一个小鼠过敏性鼻炎模型中,发现了免疫小鼠在进行重复的鼻抗原挑战时能够发展为NHR。通过使用遗传修饰小鼠和一个原始开发的T细胞转移小鼠模型,研究人员确认了NHR中分化为几种辅助细胞后CD4+T细胞的关键作用。从另一方面来讲,免疫球蛋白E/肥大细胞依赖的响应对激发鼻症状以及嗜酸性细胞在过敏性炎症位点的积累非常关键,但是却是非必要的。另外,一种非靶向肥大细胞来源的调节因子药物类固醇对减轻NHR非常有效。

最后,研究人员指出,通过靶向T细胞来源的NHR诱导的因子可能是治疗过敏性鼻炎的一种新的方法。
