Toward silencing the burden of malaria: progress and prospects for RNAi-based approaches

The discovery of RNA interference (RNAi) is one of the most significant a recent years, with potential for application beyond the laboratory to the clinic. As a tool for functional genomics, RNAi has permitted the characterization of genes in organisms that had previously remained recalcitrant to targeted gene manipulation. Efforts to understand its made of action have revealed a central role in gene regulation and host defense. Finally, as a therapeutic tool, it has shown enormous control of a large array of diseases. Here we examine how RNAi is revolutionizing malaria research in an organism, the Anopheles mosquito, that until recently was essentially resistant to genetic study, and show how its application in both the mosquito vector and the Plasmodium parasite might ultimately lead to new ways of controlling and perhaps even eradicating this devastating disease.
