[Protein traffic in Plasmodium infected-red blood cells].
To survive within erythrocytes, Plasmodium parasites have to put into place different membrane and sub-cellular compartments in order to import different nutrients and to export proteins/antigens. Infected cells pose not only a major world health risk by killing two million people per year, but also a very interesting cell biology problem, as within the erythrocyte the parasite resides inside a vacuole called the parasitophorous vacuole and as a consequence, it is separated from the blood stream by three membrane barriers, its own plasma membrane, the parasitophorous vacuole membrane and the erythrocyte plasma membrane. In spite of these three barriers the parasite is capable of secreting antigens and importing nutrients, and to do this, it has developed a complex vesicular system that extends into the red blood cell cytoplasm to the plasma membrane. Understanding how the parasite controls this extensive vesicular traffic has driven research into Plasmodium Rabs, whose potential role is discussed.
