Ebolavirus’s Foibles

Ebola virus disease poses a global health threat. Here, two studies by Wec et al. and Zhao et al. identified vulnerability in an internal fusion loop of an ebolavirus glycoprotein. Monoclonal antibodies elicited from immunization and isolated from a human survivor that recognized epitopes in this area neutralized all five ebolaviruses, guiding the development of a pan-ebolavirus immunotherapy.
