One route to malaria drug resistance found

Researchers led by Audrey Odom, MD, PhD, at Washington University School of Medicine in St. Louis have uncovered a way the malaria parasite becomes resistant to an investigational drug. The discovery also is relevant for other infectious diseases including bacterial infections and tuberculosis.

Malaria discovery may aid vaccine design

A new study provides details that will help scientists design better vaccines and drug treatments for Plasmodium vivax (P. vivax) a dangerous form of malaria common in India, Southeast Asia and South America.

Protein helps parasite survive in host cells

Researchers at Washington University School of Medicine in St. Louis have learned why changes in a single gene, ROP18, contribute substantially to dangerous forms of the parasite Toxoplasma gondii. The answer has likely moved science a step closer to new ways to beat Toxoplasma and many other parasites.

Scientists find ideal target for malaria therapy

Scientists at Washington University School of Medicine in St. Louis have identified a protein made by the malaria parasite that is essential to its ability to take over human red blood cells. “Without this protein … the infectious process stops,” says Dan Goldberg, M.D.

Nobel Laureate Kenneth Arrow discusses economics of new malarial drugs, Oct. 21

Nobel Laureate Kenneth J. Arrow will discuss “The Economics of New Antimalarial Drugs” at 2:30 p.m. Oct. 21 in the Bryan Cave Courtroom, Anheuser-Busch Hall. Arrow, a longtime professor of economics at Stanford University, recently chaired a National Institute of Medicine committee that issued a report titled “Saving Lives, Buying Time: Economics of Malaria Drugs in an Age of Resistance.” Malaria, along with tuberculosis and HIV/AIDS, is one of the big three global killers of the world’s poorest people.
