Teaching old drugs new tricks to stop malaria invasion in its tracks

Abstract

Malaria is a common and life-threatening disease endemic in large parts of the world. The emergence of antimalarial drug resistance is threatening disease-control measures that depend heavily on treatment of clinical malaria. The intracellular malaria parasite is particularly vulnerable during its brief extracellular stage of the life cycle. Wilson et al. describe a screen targeting these extracellular parasite stages and make the surprising discovery that clinically used macrolide antibiotics are potent inhibitors of parasite invasion into erythrocytes.
