研究目的: |
分析大于5岁以上儿童哮喘病人外周血及诱导痰液中Thl7及Treg细胞表达特征及其对病情的影响证实儿童哮喘病人发病机制中存在Th17/Treg失衡。并通过对IDO代谢产物的检测证实哮喘患儿气道DC是否表达IDO来抑制T细胞分化,在一定条件下IDO可能是Th17细胞向Treg转换的分子“开关”,在哮喘发病机制中起保护性作用。 |
||
|
Objectives of Study: |
To analyze the Thl7 and the Treg cell expression characteristic from peripheral blood and Induced sputum in the patient of child over 5 years old, to confirm existing Th17/Treg imbalance in pathogenesis of Childhood asthma. And through the detection of IDO metabolites, to confirmed expression of IDO to inhibit T cell differentiation in airway DC of children with asthma.Under certain conditions, IDO may be a molecular "transformation of Th17 cells into Treg switch", which may play a protective role in the pathogenesis of asthma. |
