摘要
目的观察叉头蛋白3(FoxP3)在鼻咽非角化性鳞状细胞癌中的表达情况,以探讨调节性T(Treg)细胞在鼻咽癌发生、发展中的意义。方法通过免疫组织化学(SP)法检测FoxP3在57例鼻咽非角化鳞状细胞癌和22例鼻咽部黏膜慢性炎症中的表达情况及CD8在鼻咽癌中的表达。结果在鼻咽癌组中FoxP3阳性Treg细胞数(105.05±52.22)显著高于鼻咽部黏膜慢性炎症(6.35±6.06),二者的差异有统计学意义(P<0.05)。FoxP3阳性Treg细胞的数量与患者性别及肿瘤分化程度有关(P<0.05)。结论在鼻咽非角化鳞状细胞癌中,FoxP3阳性Treg细胞的增殖可能抑制机体的抗肿瘤免疫功能,并为肿瘤细胞的免疫逃逸提供良好的环境。
Objective To investigate the expression of FoxP3 in nasopharyngeal non-keratinizing squamous cell carcinoma and the significance of regulationary T （Treg） cell in the occurrence and development of nasopharyngeal carcinoma .Methods The im-munohistochemistry staining method（SP） was used to detect the expression of FoxP3 in 57 cases of nasopharyngeal non-keratiniz-ing squamous cell carcinoma and 22 cases of nasopharyngeal mucosa with chronic inflammation ,and the expression of CD8 in naso-pharyngeal carcinoma .Results The number of Treg cell with positive FoxP3 in the nasopharyngeal carcinoma group was 105 .05 ± 52 .22 ,which was significantly higher than 6 .35 ± 6 .06 in the nasopharyngeal mucosa with chronic inflammation ,the difference be-tween them showed statistical significance（P〈0 .05） .The number of T cells with positive FoxP3 was relevant to gender and the differentiation degree of carcinoma（P〈0 .05） .Conclusion The proliferation of Treg cells with positive FoxP3 can inhibit the anti-tumor immunologic function of the patients with nasopharyngeal non-keratinizing squamous cell carcinoma and provide the favor-able environment for the immunologic escape of tumor cells .
