Abstract:
:Acute viral infection is characterised by high-level replication before prompt decline of viraemia and, commonly, viral clearance. This kinetic pattern is generally held to be due to immune control. However, infection with some viruses, notably hepatitis C (HCV), hepatitis B (HBV) and the human immunodeficiency virus (HIV), often results in chronic stable low-level spontaneously fluctuating viraemia, kinetics that are difficult to rationalize on this basis. The persistence of HCV, an RNA virus, is especially problematic and its stability, occurring despite rapid, genomic mutation is highly paradoxical. This paper outlines the hypothesis, and evidence, that viruses autoregulate replication and mutation and describes a mechanism--replicative homeostasis--explaining viral stability. Replicative homeostasis results in stable, but reactive, replicative equilibria that drive quasispecies expansion and immune escape and explain all observed viral behaviours and host responses. This paradigm implies new approaches to antiviral therapy and is broadly relevant to modulation of gene expression.
