摘要

Chronic hepatitis C virus (HCV) infection is a leading cause of end-stage liver disease in the United States, and the Centers for Disease Control has predicted that ≈10,000 Americans die annually from this disease. Since the discovery of HCV in 1989, basic research on this important pathogen has been difficult because of the lack of a robust cell-culture system. Thus, the recent development of a cell culture resulting in production of significant levels of infectious virus particles will without doubt lead to rapid progress in our understanding of the HCV viral life cycle and, it is hoped, development of better therapies. The development of molecular clones of strain H77 (genotype 1a) infectious for chimpanzees in 1997 was an important initial advance, but these clones and subsequent infectious clones of other genotype strains did not produce viruses in cell culture. Another critical advance was the development of subgenomic replicons in 1999 that permitted studies of RNA replication.
