To gain insight into dengue immunity, we characterized 145 human monoclonal antibodies (mAbs) and identified a previously unknown epitope, the envelope dimer epitope (EDE), that bridges two envelope protein subunits that make up the 90 repeating dimers on the mature virion. The mAbs to EDE were broadly reactive across the dengue serocomplex and fully neutralized virus produced in either insect cells or primary human cells, with 50% neutralization in the low picomolar range. Our results provide a path to a subunit vaccine against dengue virus and have implications for the design and monitoring of future vaccine trials in which the induction of antibody to the EDE should be prioritized. #1: Journal: NATURE Title: Recognition determinants of broadly neutralizing human antibodies against dengue viruses Authors: Rouvinski A / Guardado-Calvo P / Barba-Spaeth G / Duquerroy S / Vaney MC / Kikuti CM / Navarro Sanchez E / Dejnirattisai W / Wongwiwat W / Haouz A / Girard-Blanc C / Petres S / England P / ...Authors: Rouvinski A / Guardado-Calvo P / Barba-Spaeth G / Duquerroy S / Vaney MC / Kikuti CM / Navarro Sanchez E / Dejnirattisai W / Wongwiwat W / Haouz A / Girard-Blanc C / Petres S / England P / Supasa S / Shepard WE / Duangchinda T / Siridechadilok B / Despres P / Arenzana-Seisdedos F / Dussart P / Mongkolsapaya J / Screaton GR / Rey FA | |||||||||
