Abstract

Powell et al. describe human antibodies that bind to and neutralize multiple distantly related alphaviruses. These antibodies prevent attachment to the Mxra8 alphavirus receptor. Three cryoelectron microscopy structures of Fab in complex with Ross River (RRV), Mayaro, or chikungunya viruses reveal a conserved footprint of the broadly neutralizing mAb RRV-12.
