The surface of the Plasmodium falciparum-infected erythrocyte.

In order to navigate its complex lifecycle, the malaria parasites must interact with a range of host cells. Examples of this are the invasion of hepatocytes by sporozoites and erythrocyte invasion by merozoites. This requirement for cell recognition brings with it the need to display cognate ligands on the parasite surface, and therefore the capacity of the host to develop defences against the infection. Even at a stage where the intracellular nature of erythrocyte development would appear to offer an opportunity for the parasite to be immunologically " silent", parasite- derived proteins are found on the surface of the infected erythrocyte. This review will discuss the proteins found on or associated with the surface of the infected erythrocyte and the resulting phenotypes.
