Abstract: Hepatitis C virus (HCV) is reported to be lymphotropic under certain circumstances. In order to evaluate viral replication in peripheral blood mononuclear cells (PBMCs), a novel strand-specific RT-PCR was developed for the determination of HCV negative-strand RNA. The detection limit of this strand-specific RT-PCR was 100 copies of HCV negative-strand RNA in the presence of 1 microg liver RNA and 10(7)-10(8) copies of positive-strand RNA. False positive PCR signals occurred only when HCV positive-strand RNA exceeded 10(9) copies. With this RT-PCR, the replicative-intermediates could be detected specifically in eight of ten liver tissues, but not in any samples of serum or plasma (0/65) of patients with chronic hepatitis C. When examining the PBMCs of 46 hepatitis C patients, including 12 patients who had undergone orthotopic liver transplantation, HCV negative-strand RNA was detected in only one patient (1/46). In addition, HCV replicative intermediates were not detected in PBMCs of patients using immunosuppressive agents. It is concluded that the replication of HCV in PBMCs is very unusual.
