| 目的：研究CD3+CD56+NKT 细胞在哮喘患者急性发作期诱导痰和外周血中的比例改变，并探讨其临床意义。方法：以28 例
哮喘急性发作期患者为研究组，22 名正常人作为对照组，采用二色直接荧光素标记法和多参数流式细胞仪检测诱导痰和外周血
CD3+CD56+NKT 细胞的比例，同时检测外周血IL-4、Ig-E 及INF-γ 等水平。结果：哮喘患者急性发作期诱导痰和外周血
CD3+CD56+NKT 细胞明显高于健康对照组（P＜0.01）。哮喘患者急性发作期外周血IL-4、Ig-E 及INF-γ等水平明显高于健康对照
组（P＜0.05）。哮喘患者外周血中CD3+CD56+NKT 细胞比例与IL-4、Ig-E 及INF-γ 升高成正相关。结论：哮喘患者急性发作期诱
导痰和外周血中的CD3+CD56+NKT 细胞明显增高，CD3+CD56+NKT 细胞可能通过调节IL-4、Ig-E 及INF-γ 等细胞因子从而在哮
喘的发病机制发挥重要作用。 |

| Objective: To explore the role of CD3+ CD56+ NKT cells in induced sputum and peripheral blood in pathogenesis of
acute asthma. Methods: CD3+ CD56+ NKT cells in the induced sputum and peripheral blood in 28 patients with acute asthma and in 22
normal subjects were detected by fluorescein labeling method and flow cytometry, at the same time, the levels of IL-4, Ig-E and INF-γ
in the peripheral blood were detected. Results: The percentage of CD3+ CD56+ NKT cells in 28 patients with acute asthma was much
higher than that of induced sputum and peripheral blood in normal subjects (P<0.01). And the levels of IL-4, Ig-E and INF-γ in 28 patients
were higher than that of peripheral blood in normal subjects (P<0.05). The percentage of CD3+ CD56+ NKT cells were positively
correlated with IL-4 and NF-γ . Conclusions: CD3+ CD56+NKT cells in the induced sputum and peripheral blood in acute asthma patients
was increased, CD3+ CD56+ NKT cells perhaps play an important role in the pathogenesis of asthma by modulating IL-4,Ig-E
and INF-γ . |
