Resumen

Malaria sporozoites have the unique capacity to invade two entirely different types of target cell in the mosquito vector and the vertebrate host during the course of the parasite’s life cycle. Although little is known about the specific interaction of the sporozoite with its target cells, two sporozoite proteins, circumsporozoite (CS) and thrombospondin-related adhesive protein (TRAP), have been shown to play important roles in the invasion of both cell types. CS protein is a multifunctional protein involved in sporogony, invasion of the salivary glands, the specific arrest of sporozoites in the liver sinusoid, gliding motility of the sporozoite, and hepatocyte recognition and entry. TRAP has been shown to be critical for sporozoite infection of the mosquito salivary glands and liver cells, and is essential for sporozoite gliding motility. This review will focus on the involvement of these molecules in sporozoite motility and the invasion of host cells.
