Cellular basis of Artemisinin resistance in malaria parasites

Blood stages of the protozoan parasite Plasmodium falciparum are responsible for malaria, a disease that kills more than 400'000 people annually. During its development in red blood cells the parasite internalises a large part of the host cell cytosol (hemoglobin) in an endocytic process and digests it in its food vacuole. We recently identified a critical connection of this hemoglobin endocytosis with resistance of the parasite to the current frontline drug Artemisinin, revealing the mechanism of resistance. Artemisinin is activated by hemoglobin degradation products and we found that Artemisinin resistant parasite endocytose less. Using a toolbox of recently established approaches to…
