The Maurer's clefts of Plasmodium falciparum: parasite-induced islands within an intracellular ocean.
It is suggested that Maurer's clefts, membranous structures observed within the cytoplasm of Plasmodium-falciparum-infected human erythrocytes, play an important role in trafficking virulence proteins from the parasite to the surface of the host cell. How they fulfil this role, however, still is unclear. A recent study by Bhattacharjee et al. now suggests that the clefts function as the major conduit through which parasite-encoded proteins pass before entering the host cell. In this article we comment on the significance of this information in our understanding of the novel 'extracellular' secretory pathway of this important human pathogen.
