Using a near-atomic resolution cryo-electron microscope and imaging techniques that prevent loss of information, scientists at the La Jolla Institute for Immunology (LJI) and Regeneron Pharmaceuticals Inc. have obtained the complete 3D structure of the glycoprotein of the Ebola virus and that of the drug that neutralizes it, Inmazeb, the first FDA-approved treatment for this deadly virus. “The challenge was embracing the inherent asymmetry, the heterogeneity that is really there in biology, understanding it and collecting enough data to get all the images without needing to force any symmetry averaging,” senior author Erica Ollmann Saphire told BioWorld.
