DESCRIPTION (provided by applicant): With improved financial and technical supports, many malaria endemic nations are once again considering malaria elimination as their national goal of malaria control. To achieve this ambitious goal, one of the greatest challenges is interruption of malaria transmission worldwide. Sexual development of malaria parasite is essential for transmission of the parasite through mosquitoes. Despite its central role in the life cycle of malaria parasites, the mechanism of sexual development is still poorly understood, and this knowledge gap severely hinders the development of novel tools to interrupt malaria transmission. This project, built on our recent success in creating Plasmodium falciparum lines with male or female gametocytes tagged with a reporter gene, aims to determine the molecular differences between the two sexes of gametocytes. The comprehensive transcriptomic and proteomic data generated from this study will enable systems biology approaches to address the fundamental biology of sexual differentiation in malaria parasites. This information is also deemed critical for the development of novel drugs and vaccines for the interruption of malaria transmission. PUBLIC HEALTH RELEVANCE: Sexual development is obligatory for the transmission of malaria parasites through mosquito vectors. Interruption of malaria transmission is considered one of the greatest challenges during the malaria elimination phase. However, the mechanism of sexual differentiation in malaria parasites is still poorly understood. This project is built onour recent success to genetically manipulate the sexual stage parasites and to sort out the two sexes of the gametocyte stages, aiming to determine the differences between the male and female parasite using advanced high-throughput gene expression and protein identification approaches.

描述（由申请人提供）：随着资金和技术支持的改善，许多疟疾流行国家再次将消除疟疾作为其国家疟疾控制目标。为了实现这一雄心勃勃的目标，最大的挑战之一是阻断疟疾在全球的传播。疟疾寄生虫的性发育对于通过蚊子传播寄生虫至关重要。尽管它在生活中发挥着核心作用 人们对疟疾寄生虫的周期、性发育机制仍然知之甚少，这种知识差距严重阻碍了阻断疟疾传播的新工具的开发。该项目建立在我们最近成功创建具有标记有报告基因的雄性或雌性配子体的恶性疟原虫系的基础上，旨在确定两种性别配子体之间的分子差异。这项研究产生的全面转录组和蛋白质组数据将使系统生物学方法能够解决疟疾寄生虫性别分化的基本生物学问题。这些信息对于开发阻断疟疾传播的新药和疫苗也至关重要。 公共卫生相关性：性发育是疟原虫通过蚊媒传播的必要条件。阻断疟疾传播被认为是消除疟疾阶段的最大挑战之一。然而，人们对疟疾寄生虫的性别分化机制仍知之甚少。该项目建立在我们最近成功地对有性阶段寄生虫进行基因操纵并分选配子体阶段的两性的基础上，旨在利用先进的高通量基因表达和蛋白质鉴定方法来确定雄性和雌性寄生虫之间的差异。
