调控信号蛋白的分泌和表面展示是生物医学中细胞间通讯的关键。如果这种调节是在蛋白质水平上进行的,则还有其他优势,包括紧凑的递送和与内源性信号传导途径的直接相互作用。在这里,我们创建了一个模块化的,可推广的设计,称为保留的内质网可切割分泌(RELEASE),工程蛋白保留在内质网中,并显示/分泌响应特定的蛋白酶。该设计允许通过合成蛋白酶电路对多种合成和天然蛋白质进行功能调节,以实现不同的信号处理能力,包括逻辑运算和阈值调节。通过将RELEASE连接到额外的传感和处理电路,我们可以实现对“不可治疗的”致癌基因KRAS突变体的反应,从而提高蛋白质分泌。RELEASE应该能够为神经生物学、癌症免疫治疗和细胞移植等广泛领域提供局部、可编程的细胞间信号传递。调控信号蛋白的分泌和表面展示是生物医学中细胞间通讯的关键。在这里,作者开发了RELEASE,这是一种使用基于蛋白质的电路控制细胞间信号的模块化方法。
To program intercellular communication for biomedicine, it is crucial to regulate the secretion and surface display of signaling proteins. If such regulations are at the protein level, there are additional advantages, including compact delivery and direct interactions with endogenous signaling pathways. Here we create a modular, generalizable design called Retained Endoplasmic Cleavable Secretion (RELEASE), with engineered proteins retained in the endoplasmic reticulum and displayed/secreted in response to specific proteases. The design allows functional regulation of multiple synthetic and natural proteins by synthetic protease circuits to realize diverse signal processing capabilities, including logic operation and threshold tuning. By linking RELEASE to additional sensing and processing circuits, we can achieve elevated protein secretion in response to “undruggable” oncogene KRAS mutants. RELEASE should enable the local, programmable delivery of intercellular cues for a broad variety of fields such as neurobiology, cancer immunotherapy and cell transplantation. To program intercellular communication for biomedicine, it is crucial to regulate the secretion and surface display of signaling proteins. Here the authors develop RELEASE, a modular approach to control intercellular signals using protein-based circuits.
