The severity of the 2014–2016 ebolavirus outbreak in West Africa expedited clinical development of therapeutics and vaccines though the countermeasures on hand were largely monospecific and lacked efficacy against other ebolavirus species that previously emerged. Recent studies indicate that ebolavirus glycoprotein (GP) fusion loops are targets for cross-protective antibodies. Here we report the 3.72 Å resolution crystal structure of one such cross-protective antibody, CA45, bound to the ectodomain of Ebola virus (EBOV) GP. The CA45 epitope spans multiple faces of the fusion loop stem, across both GP1 and GP2 subunits, with ~68% of residues identical across > 99.5% of known ebolavirus isolates. Extensive antibody interactions within a pan-ebolavirus small-molecule inhibitor binding cavity on GP define this cavity as a novel site of immune vulnerability. The structure elucidates broad ebolavirus neutralization through a highly conserved epitope on GP and further enables rational design and development of broadly protective vaccines and therapeutics. The Ebola virus glycoprotein is a target for cross-protective antibodies. Here, Janus et al. report the crystal structure of the antigen-binding fragment of a pan-reactive antibody bound to a conserved epitope of the glycoprotein, facilitating rational design of cross-protective vaccines and therapeutics.
