摘要
为了解人乳头瘤病毒(HPV)对免疫Langerhans细胞(LC)的影响及HPV的致癌机理,采用地高辛配基标记的HPV6B/11DNA及HPV16/18DNA探针和抗S-100蛋白抗体,分别用原位分子杂交和免疫组化LSAB法,检测了40例食管鳞状细胞癌中HPVDNA序列及分布,重点观察了HPV感染时局部癌旁上皮内S-100蛋白阳性Langerhans细胞的分布、数量及形态改变。结果显示:在有HPV感染时,上皮内LC数量明显少于无感染者。上皮内残留的少数LC的分布及形态也有改变。我们认为,HPV可能通过减少局部的LC,破坏机体局部的免疫监视系统,并与其它致癌因素协同作用,进而导致食管癌的发生。
