研究目的:

收集非重症哮喘、重症哮喘患者气道上皮细胞、平滑肌细胞及炎症细胞建立哮喘患者 Biobank, 分析重症哮喘、非重症哮喘患者及健康人群气道上皮细胞和气道平滑肌细胞在氧化应激、固有免疫 失调和表观遗传方面的差异,从而为哮喘表观分型及新型治疗药物提供基础。  

Objectives of Study:

Airway epithelial cells, smooth muscle cells and inflammatory cells from non-severe asthma and severe asthma patients were collected to establish Biobank for asthma patients. The effects of oxidative stress and innate immunity on airway epithelial cells and airway smooth muscle cells in patients with severe asthma, non-severe asthma and healthy people were analyzed Differences in disorders and epigenetics, thus providing the basis for asthma epigenetic typing and novel therapeutic drugs.
