GB病毒C(GBV-C)是黄病毒科的成员,并且是与HCV最密切相关的人类病毒。然而,GBV-C不在肝细胞中复制,而是在淋巴细胞中复制。GBV-C在世界范围内分布,通过性传播、肠胃外传播和母婴传播。因此,HCV和HIV的共同感染是常见的。到目前为止,还没有人类疾病与GBV-C感染有关。然而,有几份报告表明GBV-C对体内HIV疾病进展具有有益作用。已经提出了不同的机制来解释这些观察结果,包括抗病毒细胞因子产生的修饰、HIV共受体表达、直接抑制HIV-1进入、T细胞活化和Fas介导的凋亡。进一步了解这些机制可能会为治疗艾滋病毒/艾滋病开辟新的策略。
GB virus C (GBV-C) is a member of the Flaviviridae family and the most closely related human virus to HCV. However, GBV-C does not replicate in hepatocytes, but rather in lymphocytes. GBV-C has a worldwide distribution and is transmitted sexually, parenterally and through mother-to-child transmission. Thus, co-infection with HCV and HIV is common. Until now, no human disease has been associated with GBV-C infection. However, there are several reports of a beneficial effect of GBV-C on HIV disease progression in vivo. Different mechanisms to explain these observations have been proposed, including modification of antiviral cytokine production, HIV co-receptor expression, direct inhibition of HIV-1 entry, T-cell activation and Fas-mediated apoptosis. Further understanding of these mechanisms may open new strategies for the treatment of HIV/AIDS.
