The single-celled parasites that cause malaria and toxoplasmosis are adept at stealing nutrients from the host animals that they infect. How they do this is, however, poorly understood. This project seeks to identify the processes by which these parasites scavenge amino acids, an essential class of nutrient, from their hosts. Using innovative experimental approaches, the project aims to identify and characterise the parasite proteins that mediate the uptake of different amino acids into the parasite. The intended outcomes of the project are to provide comprehensive insights into a fundamental aspect of parasite biology, and inform strategies to treat the diseases caused by these parasites by cutting off their nutrient supply.

引起疟疾和弓形虫病的单细胞寄生虫擅长从其感染的宿主动物中窃取营养。但是，他们如何做到这一点是很少的理解。该项目旨在确定这些寄生虫从其宿主那里清除基本营养素类别的氨基酸的过程。使用创新的实验方法，该项目旨在识别和表征介导不同氨基酸进入寄生虫的寄生虫蛋白。该项目的预期结果旨在为寄生虫生物学的基本方面提供全面的见解，并为通过切断其营养供应而为治疗这些寄生虫引起的疾病的策略提供了信息。
