| 1 | Enhancing the antihepatitis B virus immune response by adefovir dipivoxil and entecavir therapies显示文摘Chronicity of hepatitis B(CHB)infection is characterized by a weak immune response to the virus.Entecavir(ETV)and adefovir dipivoxil(ADV)are effective in suppressing hepatitis B virus(HBV)replication.However,the underlying immune mechanism in the antiviral response of patients treated with nucleoside or nucleotide analogs is not clearly understood.In this study,regulatory T cells(Tregs)and intracellular cytokines,including IL-2,interferon(IFN)-γ,tumor-necrosis factor(TNF)-α and IL-4,were measured prior to and at 12,24,36 and 48 weeks after treatment with ETV or ADV.The cytokines were increased from 24 to 48 weeks after treatment.Higher levels of Th1 cytokines were observed with ETV(n=29)versus ADV(n=28)treatment.By contrast,the numbers of Tregs in both groups were decreased.The altered cytokine profile and cellular component was accompanied by a decrease in HBV DNA levels in both groups,which may contribute to their therapeutic effect in CHB infection.Our findings suggest that the antiviral effect of the drugs may be attributed not only to their direct effect on virus suppression but also to their immunoregulatory capabilities. | Yanfang Jiang Wanyu Li Lei Yu Jingjing Liu Guijie Xin Hongqing Yan Pinghui Sun Hong Zhang Damo Xu Junqi Niu | 2011 | Cellular & Molecular Immunology2011，8，1： | 16 |
