Abstract
The study of the interaction between the West Nile virus envelope protein and monoclonal antibodies has provided insight into the molecular mechanisms of neutralization. Structural studies have identified an epitope on the lateral ridge of domain III of the West Nile virus E protein that is recognized by antibodies with the strongest neutralizing activity in vitro and in vivo. Antibodies that bind to this epitope are particularly inhibitory because they block infection at a post-attachment step and at concentrations that result in a low occupancy of the available sites on the virion.
