Study of the distribution of antibody-dependent enhancement determinants on dengue 2 isolates using dengue 2-derived monoclonal antibodies.

Abstract

Dengue 2 (DEN-2) strains isolated from children during the 1980 metropolitan Bangkok epidemic were shown to possess antigenic homogeneity when studied for determinants mediating antibody-dependent infection enhancement using DEN-2 monoclonal antibodies. All isolates possessed multiple enhancing determinants, but those associated with mild and severe dengue syndromes could not be distinguished. Either the basis of disease severity in dengue is more complex than the mere presence or absence of virus epitopes involved in enhanced infection or enhancing epitopes have differences not detected in this system with monoclonal antibodies raised to the same serotype.
