| Outline of Final Research Achievements |
Plasmodium vivax, the human malaria parasite, is believed to become a parasite of man by host switch from a monkey malaria parasite that infects Asian Old World monkeys. It remains totally unknown why P. vivax infects only human and has lost their infectivity to monkeys. To elucidate the molecular basis of the host specificity, we investigated properties of the Duffy antigen that is a surface receptor on red blood cells in hosts and the Duffy-binding protein (DBP) that is a ligand for the Duffy antigen in the parasite, and identified putative amino acid changes related to the host specificity.
