Hepatitis C virus cell culture models: an encomium on basic research paving the road to therapy development

AbstractChronic hepatitis C virus (HCV) infections affect 71  million people worldwide, often resulting in severe liver damage. Since 2014 highly efficient therapies based on directly acting antivirals (DAAs) are available, offering cure rates of almost 100%, if the infection is diagnosed in time. It took more than a decade to discover HCV in 1989 and anothe r decade to establish a cell culture model. This review provides a personal view on the importance of HCV cell culture models, particularly the replicon system, in the process of therapy development, from drug screening to understanding of mode of action and resistance, with a special emphasis on th e contributions of Ralf Bartenschlager's group. It summarizes the tremendous efforts of scientists in academia and industry required to...
