项目摘要

Project Summary This application is on preventing Human African trypanosomiasis (HAT), which kills thousands of people each year in sub-Saharan Africa. The disease is caused by African trypanosomes transmitted by the tsetse fly. No mammalian vaccines, or effective and affordable therapeutic drugs exist. In contrast, reduction of tsetse populations can be highly efficacious for disease control although traditional strategies have been difficult to sustain because they require extensive community participation in deprived, remote and war-torn regions typically afflicted by this disease. Recombinant technologies now promise the development of novel approaches, including modification of the vector competence of the fly. This application proposes to investigate the fundamental aspects of tsetse immune biology as it relates to the pathogenic trypanosomes it transmits, and the obligate mutualist symbionts it relies on for fecundity. The application has two goals: (1) to investigate the molecular basis of tsetse's refractoriness to trypanosome transmission with a focus on the role of pathogen recognition molecules, and (2) to understand the responses and the evolutionary dynamics of tsetse's immune reactions that regulate symbiotic homeostasis and vector competence. Identification of host immune proteins that result in parasite resistance can strengthen efforts that can reduce tsetse's vector competence via genetic modification. Understanding the mechanism of tolerance to symbiotic fauna may result in novel vector control strategies that aim to reduce tsetse's fecundity.

项目摘要该应用是关于预防非洲人类锥虫病（HAT），该锥虫病杀死了数千人在撒哈拉以南非洲的一年。该疾病是由采摘蝇传播的非洲锥虫引起的。不哺乳动物疫苗或有效且负担得起的治疗药物存在。相比之下，采摘者还原尽管传统策略很难很难维持因为他们需要广泛的社区参与被剥夺，遥远和饱受战争的地区通常患这种疾病。重组技术现在承诺开发新颖方法，包括修改苍蝇的向量能力。该申请建议调查 TSETSE免疫生物学的基本方面与它传播的致病性锥虫有关，它依赖于繁殖力的专有互助者。该应用程序有两个目标：（1）调查采摘锥虫传播的折射率的分子基础，重点是病原体的作用识别分子和（2）了解采取TSETSE免疫的反应和进化动力学调节共生稳态和矢量能力的反应。识别宿主免疫蛋白这会导致寄生虫的抵抗力可以加强可以通过遗传来降低采摘媒介能力的努力修改。了解对共生动物群的耐受性的机制可能会导致新的矢量控制旨在减少采摘繁殖力的策略。
