受体使细胞能够检测,处理和响应有关其环境的信息。在过去的二十年里,合成生物学家已经将天然受体的物理部分和概念重新用于工程合成受体。这些技术实现了定制的感知和响应程序,将细胞与细胞外和细胞内线索的相互作用与用户定义的响应联系起来。当与信息处理工具相结合时,这些进步使编程复杂的定制功能成为可能。近年来,人工合成受体库及其功能有了很大的发展,我们在这里用这个词来表示系统的改进和扩展。在这里,我们调查了现有的哺乳动物合成生物学工具包的蛋白质为基础的受体和信号处理组件,突出努力发展和整合一些基本的合成受体系统。然后,我们提出了一个通用的策略,工程和改善受体系统,以满足定义的功能目标,称为MEASRE(度量启用方法合成受体工程)。
Receptors enable cells to detect, process, and respond to information about their environments. Over the last two decades, synthetic biologists have repurposed physical parts and concepts from natural receptors to engineer synthetic receptors. These technologies implement customized sense-and-respond programs that link a cell’s interaction with extracellular and intracellular cues to user-defined responses. When combined with tools for information processing, these advances enable programming sophisticated customized functions. In recent years, the library of synthetic receptors and their capabilities has substantially evolved—a term we employ here to mean systematic improvement and expansion. Here, we survey the existing mammalian synthetic biology toolkit of protein-based receptors and signal processing components, highlighting efforts to evolve and integrate some of the foundational synthetic receptor systems. We then propose a generalized strategy for engineering and improving receptor systems to meet defined functional objectives called MEASRE (metric-enabled approach for synthetic receptor engineering).
