COVER The Lassa virus glycoprotein in its trimeric, viral surface state (orange) bound to a fragment of a neutralizing antibody from a human survivor (white). A second, empty antibody binding site is illuminated. Bound antibody bridges different monomers in the trimer to prevent conformational changes required for infection. The crystal structure determined by Hastie et al. provides a template for vaccine development. See page 923.
