摘要 目的:探讨金黄色葡萄球菌肠毒素B(SEB)对体外培养皮肤组织中细胞表面分子ICAM-1(CD54)和B7-2(CD86)表达的影响。方法:分别将来自整形术9例胸部皮肤组织切成面积相同的小组织块,每人份等量分为实验组及对照组。实验组SEB适当浓度施于皮肤表面,对照组PBS同法处理皮肤组织,然后将皮肤组织培养24h后快速组织切片,免疫组化(LSAB法)观察SEB刺激后皮肤组织中表皮角质形成细胞表面ICAM-1分子和郎格汉斯细胞表面B7-2分子的表达。结果:实验组表皮角质形成细胞表面分子ICAM-1和郎格汉斯细胞表面分子B7-2均表达显著高于对照组(P<0.01,P<0.05)。结论:SEB可刺激体外培养皮肤组织的表皮细胞高表达ICAM-1分子和B7-2分子。
