| pubmed-article:15504368 | pubmed:abstractText | Plasmodium vivax, one of the four parasite species causing malaria in humans, is the most widespread throughout the world, leading to nearly 80 million cases per year, mainly in Latin-America and Asia. An open reading frame encoding the Plasmodium falciparum merozoite surface protein 8 P. vivax homologue has been identified in the present study by screening the current data obtained from this parasite's partially sequenced genome. This new protein contains 487 amino-acids, two epidermal growth factor like domains, hydrophobic regions at the N- and C-termini compatible with a signal peptide, and a glycosylphosphatidylinositol anchor site, respectively. This gene's transcription and its encoded protein expression have been assessed, as well as its recognition by P. vivax-infected patients' sera. Based on this recognition, and a previous study showing that mice immunised with the Plasmodium yoelii homologous protein were protected, we consider the PvMSP8 a good candidate to be included in a multi-stage multi-antigen P. vivax vaccine. | lld:pubmed |
