摘要: 目的 探讨CD4+CD25+FOXP3+调节性T细胞(CD4+CD25+FOXP3+ Treg)百分比的改变在哮喘小鼠发病中的作用。方法 将雌性SPF级Balb/c 小鼠20只随机分为哮喘模型组、正常对照组,哮喘模型组以鸡卵白蛋白(OVA)致敏,建立模型;正常对照组以生理盐水代替OVA。分别检测小鼠外周血(PB)与肺泡灌洗液(BALF)中嗜酸性粒细胞的数量及脾脏中CD4+CD25+FOXP3+Treg的比例。结果 哮喘组与对照组小鼠脾脏中CD4+CD25+/CD4+(%)、CD4+FOXP3+/CD4+(%)、CD4+CD25+FOXP3+/CD4+(%)分别为2.50±0.12与16.64±2.11、3.92±1.23与27.72±0.15、1.34±0.25与15.60±0.62,差异均有统计学意义(P<0.05)。哮喘小鼠脾脏CD4+CD25+FOXP3+Treg占比较正常对照组明显减少。结论 研究提示CD4+CD25+FOXP3+Treg参与哮喘发病。

Abstract: Objective To observe the change of CD4+CD25+FOXP3+ regulatory T cells (Tregs) in mouse model of asthma.Methods A total of 20 Balb/c female SPF-class mice were randomly divided into normal control group (n=10) and asthma model group (n=10).The asthma model group was sensitized with 2% ovalbumin (OVA) by a combination of intraperitoneal injection to induce asthma.Mice of normal control group received normal salineinstead of OVAin equal volume.The counts of eosinophils in peripheral blood (PB)and bronchoalveolar lavage fluid (BALF) weredetected.The number of Tregs in mouse spleens was analyzed.Results The numbers of CD4+CD25+/CD4+(%),CD4+FOXP3+/CD4+(%),and CD4+CD25+FOXP3+/CD4+(%) in mouse spleens in asthma and normal control groups were 2.50±0.12 vs.16.64±2.11,3.92±1.23 vs.27.72±0.15,and 1.34±0.25 vs.15.60±0.62,respectively,showing significant differences (P<0.05).Conclusion The proportion of CD4+CD25+FOXP3+ cells in asthma mice was decreased compared to controls,suggesting that tregsmay be involved in asthma pathogenesis.
