干扰素除了具有抗病毒和直接抑制肿瘤细胞生长的生物学作用外 ,还具有免疫调节功能 ,可调节自然杀伤细胞(ＮＫ)等免疫细胞的抗瘤活性。本实验用ＭＴＴ法检测了基因重组人干扰素ａ 2ｂ对脐血和成人外周血单个核细胞ＮＫ活性的调节作用。材料与方法一、材料12份脐血标本来源于武
In addition to having antiviral and direct biological effects of inhibiting tumor cell growth, interferon also has immunomodulatory functions that regulate the antitumor activity of immune cells such as natural killer (NK) cells. In this study, MTT assay was used to detect the effect of recombinant human interferon-2b on the NK activity of cord blood and adult peripheral blood mononuclear cells. Materials and methods First, the material 12 copies of cord blood samples from Wu
