| Outline of Final Research Achievements |
In Plasmodium parasites, TCA cycle is not essential for survival of asexual-blood-stage parasites, but is required for survival of mosquito-stage parasites. Whereas, two of the eight mitochondrial TCA cycle enzymes, fumarate hydratase (FH) and malate:quinone oxidoreductase (MQO), could not be genetically ablated in asexual-blood-stage Plasmodium falciparum. However, the importance of FH and MQO for asexual-stage parasite viability and growth in cerebral malaria is unclear. In this study, we revealed that MQO is a key molecule for metabolic cross-talk between purine salvage pathway and TCA cycle in rodent malaria parasites, Plasmodium berghei ANKA, and is involved in parasite viability during the blood stage. The finding that MQO is involved in the viability, the growth of asexual-blood-stage parasites and the development of experimental cerebral malaria suggest that MQO would be a potential target for the treatment of severe malaria.
