我们已经翻译了一种强大的遗传工具,由设计药物(DREADD)独有激活的设计受体,从哺乳动物系统到果蝇黑腹果蝇,以选择性、快速、可逆和剂量依赖的方式控制苍蝇的行为和生理过程。DREADD是毒鼠碱型乙酰胆碱G蛋白偶联受体,进化的目的是失去与乙酰胆碱的亲和力,并能够被其他生物惰性化学物质氯氮平-N-氧化物完全激活。我们证明了它有能力控制幼虫和成虫的各种行为和过程,包括心率、感觉处理、昼夜行为、学习和记忆以及求偶。这种特殊技术的优势包括对行为的剂量反应控制,不需要专门的设备,以及基本上所有神经元和非神经元苍蝇组织中远程控制信号的能力。
We have translated a powerful genetic tool, designer receptors exclusively activated by designer drugs (DREADDs), from mammalian systems to Drosophila melanogaster to selectively, rapidly, reversibly, and dose-dependently control behaviors and physiological processes in the fly. DREADDs are muscarinic acetylcholine G protein-coupled receptors evolved for loss of affinity to acetylcholine and for the ability to be fully activated by an otherwise biologically inert chemical, clozapine-N-oxide. We demonstrate its ability to control a variety of behaviors and processes in larvae and adults, including heart rate, sensory processing, diurnal behavior, learning and memory, and courtship. The advantages of this particular technology include the dose-responsive control of behaviors, the lack of a need for specialized equipment, and the capacity to remotely control signaling in essentially all neuronal and nonneuronal fly tissues.
