Dynamics of hepatitis B virus clearance in chimpanzees.

ABSTRACT: Mathematical modeling was performed to test the extent to which cytopathic and noncytopathic T cell effector functions contribute to resolution of hepatitis B virus (HBV) infection in three acutely infected chimpanzees. Simulations based exclusively on cytopathic functions show a poor fit to the data and would require the destruction and regeneration of approximately 11 livers for clearance to occur. In contrast, a simulation based on a combination of cytopathic and noncytopathic functions provided a significantly better fit to the data (P < 0.001) and required as much as 5-fold less destruction to clear the virus from the liver. The best fit simulation supports the notion that during the early phase of HBV clearance, noncytopathic T cell effector mechanisms inhibit viral replication and g
