本文采用ＢＳＡ－ＥＬＩＳＡ方法，研究ｒＨｕＩＦＮ－γ（ＩＦＮγ）对体外培养的健康人及恶性肿瘤患者外周血单核细胞表达ＨＬＡ－ＤＲ抗原的影响。结果表明：ＩＦＮγ能促进两者单核细胞ＨＬＡ－ＤＲ抗原的表达，但ＩＦＮγ对健康人单核细胞ＨＬＡ－ＤＲ表达促进程度较恶性肿瘤患者强（Ｐ＜０．０５）。
In this study, BSA-ELISA was used to study the effect of rHuIFN-γ(IFNγ) on the expression of HLA-DR antigen in peripheral blood mononuclear cells of healthy and malignant patients in vitro. The results showed that IFNγ can promote the expression of HLA-DR antigen in monocytes, but IFNγ promotes the expression of HLA-DR in monocytes of healthy people more than malignant tumors (P<0.05).
