Research Abstract

We found that Hepatitis C virus (HCV) associate with Apolipoprotein E (ApoE) prior to virus release. Moreover, we clarified that ApoE is important factor for HCV infectivity. Infectivity of HCV to cells that were suppressed endogenous LDLR as well as SR-BI was severally reduced. Furthermore, suppression of both the receptors didn't alter the infectivity to cells that were suppressed either one of the receptors. These results suggest that the infectivity of HCV required both LDLR and SR-BI.
