Apical membrane antigen-1 (AMA1) is important for Plasmodium parasite invasion, but surface polymorphisms in P. falciparum AMA1 hamper vaccine and antibody development. Here the authors identify a humanised single-domain antibody molecule, an i-body, that binds to AMA1 of all Plasmodium parasites examined and inhibits parasite invasion.
