A clash to conquer: the malaria parasite liver infection.

All mammalian malaria parasite species have an initial tissue stage in liver cells. The liver stage produces new parasite forms that can enter and live inside red blood cells. Accordingly, the first place of residence provides parasites with a radically different cellular and molecular environment from their subsequent red blood cell home. Liver stages have remained refractory to reveal their secrets, yet the last few years have seen several advances in elucidating their biology. This review looks at the more recent findings concerning the liver stage-host hepatocyte association, some of which may become powerful weapons in the prevention of malaria infection. We also outline areas of liver stage research and technological development that provide promising foci to accelerate a better understanding of this most elusive of the parasites many life cycle stages.
