Structural Basis for Antibody Inhibition of Flavivirus NS1–Triggered Endothelial Dysfunction

Scientists present three crystal structures of full-length dengue virus NS1 complexed with a flavivirus–cross-reactive, NS1-specific monoclonal antibody, 2B7, at resolutions between 2.89 and 3.96 angstroms. These structures reveal a protective mechanism by which two domains of NS1 are antagonized simultaneously.
