噬菌体是运送各种货物的多面手,包括纳米材料、核酸和小分子。一个潜在的重要应用是治疗抗药性感染。所有这些应用都需要对噬菌体进行分子工程,包括化学修饰和基因工程。噬菌体非常容易受到这种工程的影响。我们回顾了一些例子,包括受控噬菌体疗法。我们认为,噬菌体支持广泛工程的能力可能源于细菌和噬菌体之间数十亿年来的“军备竞赛”,这场竞赛选择了在快速进化变化面前保持稳健的序列和结构。这导致了对自然进化突变和合成分子工程的高度耐受性。
Phages are versatile agents for delivering a variety of cargo, including nanomaterials, nucleic acids, and small molecules. A potentially important application is treatment of antibiotic-resistant infections. All of these applications require molecular engineering of the phages, including chemical modification and genetic engineering. Phages are remarkably amenable to such engineering. We review some examples, including for controlled phage therapy. We suggest that the ability of phages to support extensive engineering may have evolutionary origins in the billions-year-old 'arms race' between bacteria and phages, which selects for sequences and structures that are robust in the face of rapid evolutionary change. This leads to high tolerance of both naturally evolved mutations and synthetic molecular engineering.
