摘要 目的研究鹰嘴豆芽素A(biochanin A,BioA)对HIV-1活性及CD4+淋巴细胞早期活化作用的影响。方法①以MT-2和H9/HIV-1ⅢB细胞或HIV-1病毒共培养建立HIV-1感染模型,以不同浓度的BioA干预该过程,观察细胞融合情况和测定培养上清中的p24抗原含量变化,以评价BioA的抗HIV-1活性。②以PHA刺激剂诱导人外周血CD4+淋巴细胞活化,利用流式细胞术检测不同浓度BioA对早期活化标志CD69分子的表达影响。结果①BioA在本实验所设浓度下均能减少由HIV-1介导的细胞融合数(EC50=5.1μmol.L-1,SI=39)及p24抗原的表达量(EC50=38μmol.L-1,SI=5.2)。②终浓度5、10、25、50μmol.L-1的BioA对CD4+淋巴细胞早期活化抗原CD69表达具有明显抑制作用(P<0.01),其中50μmol.L-1达到最大抑制率,能使活化率从(60.42±0.52)%降低到(19.70±0.38)%。结论BioA具有抗HIV-1介导的细胞融合和HIV-1复制的活性及抑制CD4+淋巴细胞早期活化作用。 Aim To investigate the inhibitory effect of biochanin A (BioA) on HIV-1 and the early activation of CD4^+ lymphocytes. Methods The inhibitory activ- ity of BioA on HIV-1 was detected by HIV-1-mediated cell fusion and p24 production, respectively. Double fluorescent staining together with flow cytometry were adopted to analyze the influence of BioA on the expression of the early activation antigen CD69 on human CD4^+ lymphocytes under stimulation of PHA. Results BioA could reduce the cell fusion mediated by HIV-1 ( EC50 = 5.1μmol· L^- 1, SI = 39 ), the expression of p24 ( EC50 = 38μmol· L^- 1, SI = 5.2) and early activation antigen CD69 on human CD4^+ lymphocytes (effective concentration: 5, 10, 25 and 50 μmol· L^- 1). Conclusion BioA can inhibit the activity of HIV-1 and the early activation of human CD4^+ lymphocytes.
