Mapping the anatomy of a Plasmodium falciparum MSP-1 epitope using pseudopeptide-induced mono- and polyclonal antibodies and CD and NMR conformation analysis

Antigen structure modulation represents an approach towards designing subunit malaria vaccines. A specific epitope's ? carbon stereochemistry, as well as its backbone topochemistry, was assessed for obtaining novel malarial immunogens. A variety of MSP-138–61 Plasmodium falciparum epitope pseud...

A specific epitope's ? carbon stereochemistry, as well as its backbone topochemistry, was assessed for obtaining novel malarial immunogens. A variety of MSP-138–61 Plasmodium falciparum epitope pseudopeptides derived were synthesised, based on solid-phase pseudopeptide chemistry strategies; these included all-l, all-d, partially-d substituted, all-?-[NH-CO]-Retro, all-?-[NH-CO]-Retro-inverso, and ?-[CH2NH] reduced amide surrogates. We demonstrate that specific recombinant MSP-134–469 fragment binding to red blood cells (RBCs) is specifically inhibited by non-modified MSP-142–61, as well as by its V52-L53, M51-V52 reduced amide surrogates and partial-d substitutions in K48 and E49. In vivo tests revealed that reduced amide pseudopeptide-immunised Aotus monkeys induced neutralising antibodies specifically recognising the MSP-1 N-terminus region. These findings support the role of molecular conformation in malaria vaccine development.application/pdfhttps://doi.org/10.1016/j.jsb.2004.04.010ISSN: 1047-8477EISSN: 1095-8657https://repository.urosario.edu.co/handle/10336/28112engElsevier122No. 1110Journal of Structural BiologyVol. 148Journal of Structural Biology, ISSN: 1047-8477;EISSN: 1095-8657, Vol.148, No.1 (2004); pp. 110-122https://www.sciencedirect.com/science/article/pii/S1047847704001030Restringido (Acceso a grupos específicos)http://purl.org/coar/access_right/c_16ecJournal of Structural Biologyinstname:Universidad del Rosarioreponame:Repositorio Institucional EdocURMolecular mimicryMerozoite surface protein-1 (MSP-1)PseudopeptideTopologyStereochemistryMapping the anatomy of a Plasmodium falciparum MSP-1 epitope using pseudopeptide-induced mono- and polyclonal antibodies and CD and NMR conformation analysisMapeo de la anatomía de un epítopo de Plasmodium falciparum MSP-1 usando anticuerpos mono y policlonales inducidos por pseudopéptidos y análisis de conformación de CD y RMNarticleArtículohttp://purl.org/coar/version/c_970fb48d4fbd8a85http://purl.org/coar/resource_type/c_6501Lozano, José ManuelEspejo, FabiolaOcampo, MarisolSalazar, Luz MaryTovar, DianaBarrera, NubiaGuzmán, FannyPatarroyo, Manuel Elkin10336/28112oai:repository.urosario.edu.co:10336/281122022-05-02 07:37:21.959605https://repository.urosario.edu.coRepositorio institucional EdocURedocur@urosario.edu.co
