Elena Levashina of the Max Planck Institute for Infection Biology in Germany and Kelly Lee of the University of Washington in the U.S. will use cryoelectron tomography to image the three-dimensional ultrastructure of a protein on the surface of the malaria-causing parasite Plasmodium falciparum to help design better vaccines. Malaria kills half a million people annually, but there are still no highly effective vaccines available. One of the parasite's coat proteins, CSP, is a prime target for vaccine development.
