Functional genomic technologies applied to the control of the human malaria parasite, Plasmodium falciparum.

ABSTRACT

Infection with any of the four species of Plasmodium single cell parasites that infects humans causes the clinical disease, malaria. Of these, it is Plasmodium falciparum that is responsible for the majority of the 1.5-2.3 million deaths due to this disease each year. Worldwide there are between 300-500 million cases of malaria annually. To date there is no licensed vaccine and resistance to most of the available drugs used to prevent and/or treat malaria is spreading. There is therefore an urgent need to develop new and effective drugs and vaccines against this devastating parasite. We have outlined a strategy using a combination of DNA-based vaccines and the data derived from the soon-to-be completed P. falciparum genome and the genomes of other species of Plasmodium to develop new vaccines against malaria. Much of the technology that we are developing for vaccine target identification is directly applicable to the identification of potential targets for drug discovery. The publicly available genome sequence data also provides a means for researchers whose focus may not be primarily malaria to leverage their research on cancer, yeast biology and other research areas to the biological problems of malaria.
