Changes in the expression of TLR9 in PBMCs and pulmonary macrophages during allergic rhinitis and asthma attacks

摘要:近年来单核细胞-巨噬细胞系统及Toll样受体9(Toll-like receptor 9, TLR9)在过敏性疾病中的作用引起了关注。本文采用流式细胞术,分析了过敏性鼻炎(Allergic rhinitis, AR)和过敏性哮喘(Allergic asthma, AA)及过敏性鼻炎合并哮喘((Allergic rhinitis with allergic asthma, ARA)外周血TLR9+单核细胞的表达变化。并应用小鼠的AR和AA模型对过敏原激发后小鼠血液单核细胞、肺组织中巨噬细胞TLR9的表达变化进行了探讨。发现AR、AA及ARA外周血单核细胞群中TLR9+细胞比例显著升高,代表每个细胞内TLR9分子表达数量的MFI表达增加。大籽蒿过敏原提取物(ASWE)、屋尘螨过敏原提取物(HDME)刺激AR、AA模型小鼠血液TLR9+单核细胞、肺组织巨噬细胞比例及TLR9 MFI的表达水平增高。高亲和力IgE受体基因敲除的AR和AA模型小鼠较野生型( WT)小鼠的TLR9+单核细胞及巨噬细胞比例显著减少,提示过敏原提取物诱导的TLR9+细胞表达上调是由FcεR依赖和非依赖性途径共同实现的。
