Immunogenic four amino acid epitope against Plasmodium vivax

摘要

An agent and pharmaceutical formulations of the agent containing a synthetic peptide of the human malaria Plasmodium vivax, containing at least one repeat of a synthetic peptide having the amino acid sequence Ala-Gly-Asp-Arg (AGDR) which is a protective epitope found on the circumsporozoite (CS) protein of the sporozoites of the human malaria Plasmodium vivax. When a monoclonal antibody specific for this four amino acid sequence binds to the CS protein of the P. vivax sporozoite in vivo, infection is prevented.
