GB virus C (GBV-C) is a common virus that does not appear to cause disease. GBV-C persists in up to 50% of exposed individuals, and virus replication appears to be in lymphocytes including CD4+ T cells. GBV-C infection is common among HIV-positive people, and several studies have found that HIV-positive individuals co-infected with GBV-C survive for statistically significantly longer periods of time than people without GBV-C. In vitro studies suggest that GBV-C inhibits HIV replication and alters cytokine, chemokine and chemokine receptor expression. Thus, GBV-C may be a major factor influencing the natural history of HIV disease.
丙型肝炎病毒(GBV-C)是一种常见病毒,似乎不会引发疾病。GBV-C在高达50%的暴露个体中持续存在,病毒复制似乎发生在包括CD4 + T细胞在内的淋巴细胞中。GBV-C感染在艾滋病毒阳性人群中很常见,多项研究发现,与未感染GBV-C的人相比,同时感染GBV-C的艾滋病毒阳性个体存活时间在统计学上显著更长。体外研究表明,GBV-C可抑制艾滋病毒复制,并改变细胞因子、趋化因子和趋化因子受体的表达。因此,GBV-C可能是影响艾滋病毒疾病自然病程的一个主要因素。
