摘要
目的 研究白细胞介素-2(IL-2)对肝癌细胞侵袭力及转移力相关因素的调节作用。 方法 用IL-2处理肝癌细胞,采用流式细胞仪分析肝癌细胞表面抗原分子的表达水平,用附壁试验检测肝癌细胞对细胞外基质的亲和力,用细胞聚集试验检测肝癌细胞的聚集能力以研究IL-2对肝癌细胞侵袭力及转移力相关因素的调节作用。结果 经高浓度和低浓度IL-2处理后,肝癌细胞表面ICAM-1及HLA-I表达均增加,CD44表达减少,肝癌细胞对细胞外基质的亲和力及肝癌细胞聚集程度均降低。 结论 IL-2可明显增加肝癌细胞ICAM-1及HLA-I的表达,抑制CD44表达,抑制肝癌细胞对细胞外基质的亲和力及肝癌细胞的聚集作用。因此可抑制肝癌细胞的侵袭力和转移力。
