项目摘要
The ability to deliver pathogen-resistance genes into mosquito populations has long been
sought as a potential alternative for disrupting dengue or malaria transmission where funds and
infrastructure are the limiting factors in effective mosquito control. The recent development of
effective gene drive transgenes based on CRISPR/Cas9 has largely solved the technical
challenges of achieving super-Mendelian introgression, however there exists no means to
control or recall such genetic elements once released making safety testing in the relevant
environments problematic. Drosophila melanogaster is an extremely trackable genetic model
organism, while Aedes aegypti is the main vector of dengue, yellow fever and chikungunya
viruses, as well as a model system for studies of other mosquitoes. In this project, we will
employ both D. melanogaster and A. aegypti to evaluate a transgene self-elimination strategy
whereby a transgene can be pre-programmed to first drive itself into a population and then
remove itself from the population without any intervention from the experimenter. We will
characterize some of the limiting parameters of the self-elimination system, such as direct
repeat length (Aim 1) and number and type of nuclease targeting sites (Aim 2). Finally, we will
test this self-elimination strategy in the context of an active gene drive in both flies and
mosquitoes (Aim 3). Our innovative approach takes advantage of naturally occurring processes
that are conserved throughout eukaryota to completely eliminate all transgenic sequences
following potential field releases. Thus, we anticipate that this project will dramatically alter the
National and International conversations concerning gene drive technology as a whole, and will
raise expectations for what is possible in any future trial to generate pathogen-resistant
mosquitoes.
将病原体抗性基因传递到蚊子种群中的能力长期以来一直是
作为阻断登革热或疟疾传播的潜在替代方案,
基础设施是有效控制蚊子的限制因素。的最新发展
基于CRISPR/Cas9的有效基因驱动转基因在很大程度上解决了技术难题,
实现超孟德尔基因渗入的挑战,但是没有办法
控制或召回这些基因元件,一旦释放,在相关的安全测试
环境问题。黑腹果蝇是一种非常容易追踪的遗传模型
埃及伊蚊是登革热、黄热病和基孔肯雅热的主要传播媒介
病毒,以及用于研究其他蚊子的模型系统。在这个项目中,我们将
使用D。melanogaster和A.埃及评估转基因自我消除策略
由此转基因可以被预编程以首先将其自身驱动到群体中,然后
在没有实验者任何干预的情况下从种群中消失。我们将
描述自消除系统的一些限制参数,例如直接
重复长度(Aim 1)和核酸酶靶向位点的数量和类型(Aim 2)。最后我们将
在两种果蝇的主动基因驱动背景下测试这种自我消除策略,
蚊子(目标3)。我们的创新方法利用自然发生的过程
这些基因在真核生物中是保守的,
释放了潜在的磁场因此,我们预计,该项目将大大改变
关于基因驱动技术的国家和国际对话,并将
提高了对未来任何试验中可能产生的病原体抗性的期望,
