Functional and structural characterization of a two-MAb cocktail for delayed treatment of enterovirus D68 infections

Although enterovirus D68 poses a major global threat to children, neither vaccines nor therapeutics are currently available. Using Cryo-EM, Zhang et al. show that two murine-derived monoclonal antibodies with therapeutic efficacy neutralize virions via binding to the canyon region, creating steric hindrance for sialic acid receptor binding.
