What the study found
The study shows how to include inheritance of intracellular viral RNA in a multiscale model of hepatitis C virus (HCV) infection. It also reports that proliferation of infected hepatocytes can allow infection to persist even when the basic reproductive number is below one.
Why the authors say this matters
The authors say multiscale models have been important for understanding direct-acting antivirals, and that incorporating infected-cell proliferation into these models is subtle because daughter cells inherit viral RNA from the mother cell. The study suggests this inheritance needs to be accounted for in modeling HCV infection.
What the researchers tested
The researchers developed a multiscale mathematical model of HCV infection that explicitly includes intracellular viral RNA and the inheritance of that RNA during infected hepatocyte proliferation. They show that the model is mathematically equivalent to a system of ordinary differential equations and analyze that ODE system using bifurcation analysis.
What worked and what didn't
The model successfully incorporated viral RNA inheritance within the multiscale framework. The analysis showed that proliferation of infected hepatocytes can lead to infection persistence even when the basic reproductive number is less than one.
