Expression of functional HCV receptor candidates in nonhepatic cells. (A) Expression of hCD81 in nonhepatic cells was determined by flow cytometry. PE, phycoerythrin. (B) Expression levels of SR-B1, CLDN, and OCLN in the nonhepatic cells were determined by immunoblotting. (C) The nonhepatic cell lines were inoculated with pseudotype VSVs bearing no envelope protein (deltaG), HCV envelope proteins of genotype 1b Con1 strain (HCVpv), or VSV G protein (VSVpv), and luciferase expression was determined at 24 h postinfection.
