Hepatitis

HCV variability, the immune system and resistance to antiviral drugs

Several novel antiviral treatments for HCV are in preclinical or clinical development, and most target viral enzymes and their functions. These new drugs all potentially select for resistant viral variants, both in vitro and in vivo; viral resistance is, therefore, likely to become an important issue in clinical practice.
