Differential dependence of the infectivity of HIV-1 group O isolates on the cellular protein cyclophilin A.

abstract：:Hepatitis C virus (HCV) infection often leads to the development of hepatocellular carcinoma (HCC), but its molecular mechanism has not been clearly elucidated. Previously, transgenic mice constitutively expressing HCV core protein have been shown to develop HCC, suggesting a pivotal role of the core protein in hepato...
