(17) Currently, preclinical studies with multivalent vaccines (four to six AMA1 alleles) show promise, inducing a more broadly cross-reactive antibody response. (16) A bivalent 3D7 and FVO PfAMA1 vaccine, also tested in Phase IIb trials, failed to protect because of the poor immunogenicity of the alum formulation. falciparum AMA1 genotypes, reflecting the extensive sequence polymorphisms in this antigen.

falciparum, (15) but in a Phase IIb clinical trial in Mali, a 3D7 PfAMA1 vaccine provided protection against only a subset of P. AMA1 has been a leading candidate for inclusion in a vaccine against P. falciparum in vitro and contribute to the adaptive immune response that partially protects exposed individuals against malaria. (13, 14) Antibodies to AMA1 can block red cell invasion by P. (11) AMA1 is a type I integral membrane protein, (12) the extracellular region of which consists of three domains based on the connectivities of its eight intramolecular disulfide bonds: an N-terminal domain I, a central domain II, and a C-terminal domain III. (5-9) Further, a conditional knockdown of PfAMA1 severely impaired the parasiteвЂ™s ability to invade red cells, (10) and a complete gene knockout is not viable in P. falciparum AMA1.ДЄpical membrane antigen 1 (AMA1) forms part of the moving junction complex essential for erythrocyte invasion by Plasmodium merozoites, and ligands that disrupt AMA1 function inhibit the growth in vitro of P. Collectively, these results provide valuable insights that should contribute to the design of strain-transcending agents targeting P.

We also investigated the domain II loop, a key region involved in inhibitor binding, by comparison of multiple AMA1 crystal structures. A combination of normalized B factor analysis and computational methods has been used to investigate the flexibility of the domain I loops and how this correlates with their roles in determining the strain specificity of human antibody responses and inhibitory peptides.

We compare our new structure to those of AMA1 from P.

Here we present the X-ray crystal structure of AMA1 domains I and II from Plasmodium falciparum strain FVO. Blocking this proteinвЂ“protein interaction represents a potential route to controlling malaria and related parasitic diseases, but the polymorphic nature of AMA1 has proven to be a major challenge to vaccine-induced antibodies and peptide inhibitors exerting strain-transcending inhibitory effects. Apical membrane antigen 1 (AMA1) interacts with RON2 to form a protein complex that plays a key role in the invasion of host cells by malaria parasites.
