Derived from extracts of the sweet wormwood plant, artemisinin-based antimalarial drugs are recommended for use global y; several hundred mil ion doses are given every year. Yet they were developed without any clear idea of their molecular target. In 2003, we identified PfATP6 as the likely target for artemisinin, and since then have generated more evidence in support of our initial findings. The unusual chemical structure of artemisinin resembles that of a Knowing the identity of the artemisinin target is extremely calcium pump inhibitor, thapsigargin. This led us to suggest that important. It will provide a way to identify mechanisms of artemisinin might also act on a calcium pump.

Although their metabolism is complex and incompletely understood, malaria parasites rely on a continuous supply of glucose from the host. This is taken up by a single sugar transporter, PfHT.

monitor for resistance to antimalarial drugs.
The antimalarial drug mefloquine was introduced into Thailand in 1984. Within six years, it was rendered near useless by the development of drug resistance. By adapting methods of DNA amplification, we were able to show that drug resistance was caused primarily by duplication of a specific parasite gene, pfmdr1, coding for a drug transporter protein. This test has gone on to be used by the Worldwide Antimalarial Resistance Network (WWARN) to monitor for emerging drug resistance.
Initial attempts to identify the causes of mefloquine resistance threw up conflicting results. As well as mutations affecting Our approach has been widely adopted to track the emergence individual proteins, resistance could reflect duplications of genes of drug resistance. Global y, it formed part of the WWARN toolkit such as pfmdr1, a relative of which renders some tumours resistant for monitoring drug resistance. Notably, pfmdr1 expansion is to anticancer drugs. In the early 2000s, however, assaying not yet a major factor in Africa, but this situation could change increases in gene copy number was not straightforward.
with increased antimalarial use, emphasising the need for active We developed a new technique, based on the polymerase chain reaction (PCR), to detect copy number changes in pfmdr1.

With David Fidock in New York, we also showed that genetical y modifying parasites to lower pfmdr1 copy number increased their sensitivity to mefloquine and a range of other antimalarials.

A practical guide to antimalarial use

Rigorous clinical trials have helped to establish the most
appropriate treatment regimes for children with malaria.
Young children are at particular risk The development of artemisinin-based drugs provided a much- needed boost to the antimalarial armamentarium. Drug treatment has the twin aims not just of treating individuals but also of preventing the spread of parasites, cal ing for careful design of drug regimes, routes of drug delivery and an awareness of how drugs are metabolised in the body. We have been involved in numerous international clinical trials that have shaped global antimalarial policy and national practice. Children are at particular risk of malaria. Severely ill children may be unable to take antimalarial drugs by mouth and, in areas of poor health infrastructure, injection of drugs may not be practical. In Ghana, we showed that that intrarectal administration of still delivering the same quantity of drug – was no worse than the artesunate was a suitable alternative, and later contributed to a standard five-dose regime.

Most childhood deaths from malaria occur within the first 24 hours of hospitalisation. One factor suggested to be a risk factor for severe malaria is excessive fluid loss, leading some to propose rapid rehydration for severely ill infants. Our studies in Gabon, however, found no evidence that severe malaria was associated with excessive fluid loss.
Determining body fluid levels experimental y is difficult, and many studies have assessed dehydration through clinical proxy measures. We used careful experimental methods to measure body fluids in children with severe and moderate malaria, and also validated a relatively simple method of determining fluid levels by measuring the flow of small electrical currents between hands and feet.
We found that severe malaria was typical y associated with mild dehydration, but found no evidence that the severity of symptoms was linked to the degree of dehydration.
