Abstract
The attenuation of Plasmodium parasites by either radiation or targeted gene deletion can result in viable sporozoites that invade the liver and subsequently arrest. The death of the growth-arrested liver stage parasite and the ensuing recognition by the immune system of parasite antigens promotes protective immunity in immunized mice and humans. The methods described below will enable researchers to determine the efficacy of radiation-attenuated and genetically attenuated rodent malaria sporozoite immunizations against infectious sporozoite challenge, and study protective immunity in immunized mice. In addition, by determining the time of arrest of genetically attenuated parasite liver stages and the mechanisms of clearance, researchers will be able to correlate biological features of the growth-arrested parasites with their ability to promote protective immunity.
