Abstract： 目的探讨角质形成细胞生长因子(KGF)及神经细胞生长因子(NGF)与银屑病的关系及银屑病皮损中间质细胞与角质形成细胞的相互作用.方法应用免疫组化技术分别检测33例银屑病患者皮损、8例非皮损和13例正常人皮肤中KGF、KGF受体、NGF、NGF受体的表达.结果KGF、KGF受体在银屑病患者基底层和棘细胞下层有极强的表达,与非皮损组及正常对照组间差异有显著性(P<0.05),而非皮损组与正常对照组间差异无显著性(P>0.05).KGF、KGF受体在真皮层未见表达.NGF、NGF受体则主要表达在颗粒层和棘细胞上层,皮损组与非皮损组之间及非皮损组与正常组之间均差异有显著性(P<0.05).结论银屑病患者皮损中KGF及NGF可能介导了角质形成细胞的增殖与分化不全;银屑病皮损中存在着间质细胞和角质形成细胞相互作用的紊乱.
