Complementary DNA microarray analysis of human livers cannot exclude the influence of the immunological response. In this study, complementary DNA microarray analysis was performed under immunodeficient conditions with human hepatocyte chimeric mice, and gene expression profiles were analyzed by hepatitis B virus (HBV) infection and/or interferon treatment. The expression levels of 183 of 525 genes upregulated by interferon treatment were significantly suppressed in response to HBV infection. Suppressed genes were statistically significantly associated with the interferon signaling pathway and pattern recognition receptors in the bacteria/virus recognition pathway (P = 1.0 × 10(-8) and P = 1.2 × 10(-8), respectively). HBV infection attenuated virus recognition and interferon response in hepatocytes, which facilitated HBV escape from innate immunity.
对人类肝脏的 cDNA 微阵列分析不能排除免疫反应的影响。在这项研究中,在免疫缺陷条件下用人肝细胞嵌合小鼠进行 cDNA 微阵列分析,并通过乙型肝炎病毒 (HBV) 感染和/或干扰素治疗分析基因表达谱。干扰素治疗上调的 525 个基因中的 183 个在 HBV 感染时表达水平显著受到抑制。受抑制的基因与干扰素信号通路和细菌/病毒识别途径中的模式识别受体呈统计学显著相关(分别为 P = 1.0×10(-8) 和 P = 1.2×10(-8))。HBV 感染减弱了肝细胞中的病毒识别和干扰素反应,从而使 HBV 逃避先天免疫。
