摘要 目的研究各级宫颈上皮内瘤变(CIN)组织中T-bet、GATA3、Foxp3的表达。方法将宫颈组织按病变程度分为宫颈炎症组、CINⅠ级组、CINⅡ级组和CINⅢ级组,组织包埋、切片后进行镜下观察及免疫组化检测。结果各组病变组织中T淋巴细胞数量无显著性差异(P>0.05);T-bet阳性细胞数量随病变进展增多,有统计学差异(P<0.05)。GATA3阳性细胞数量随病变进展而减少,宫颈炎症与CINⅠ级、CINⅡ级病变组织中GATA3表达无显著性差异(P>0.05),CINⅠ级与CINⅡ级组间GATA3表达具有统计学差异(P<0.05),CINⅢ与其他各组间均有统计学差异(P<0.05)。宫颈炎症、CINΙ级及CINⅡ级各组病变组织中Foxp3表达无显著性差异(P>0.05),CINⅢ级与其他各组间Foxp3表达均有统计学差异(P<0.05);CINⅢ级Foxp3阳性细胞数量明显增多。结论宫颈CIN局部免疫微环境中,Th1、Th2类细胞及Treg细胞都参与了宫颈CIN的免疫反应,在宫颈CIN的病程进展中存在Th1/Th2平衡向Th1漂移,Treg细胞可能通过免疫抑制作用参与病变进展,并最终导致宫颈癌的发生。
