The surface of Toxoplasma: more and less.


As for any intracellular parasite, the surface of the Apicomplexan parasite Toxoplasma gondii must fulfil many functions including a role in attachment, signalling, invasion, transport and interaction with the immune response of the host. In this review, we describe the current state of knowledge on the molecules that are found on the surface of the different developmental stages of this parasite and speculate as to how at least some of these multiple functions are fulfilled. Special emphasis is given to the growing family of surface antigens that are related to the tachyzoite-specific surface antigen 1. We conclude that the surface (of tachyzoites, at least) is both more and less complex than previously thought: there are more proteins present but their sequences suggest that the majority may share a similar overall structure typified by surface antigen 1.
