摘要:

细胞穿透肽(CPP)是一类由5~30个天然或人造氨基酸残基组成的短肽序列,具有增强细胞摄取抗原并促进穿越各种生物屏障的能力,因其高效、独特的跨膜运输能力成为近年来生物医药领域的研究热点。噬菌体展示技术(PDT)是一种通过对噬菌体DNA进行基因改造,从而在噬菌体表面展示的分子技术,其包含的遗传序列可将表型与基因型相连,该技术允许不同的肽库在噬菌体颗粒表面表达,并能选择与靶标特异性结合的多肽,且其具有简单、高效和低成本等优点。因此,可利用其在不损伤其他正常细胞的情况下实现靶向治疗,为研发靶向递药新型载体,实现靶向药物投递奠定了基础。本文综述了细胞穿透肽以及利用噬菌体展示技术筛选细胞穿透肽的研究进展,同时也为饲用抗生素替代品的研究与开发提供更有效的思路和方法,并进一步为胞内致病菌的精准杀伤提供新的策略和研究方向。

Abstract:

Cell penetrating peptide (CPP) is a kind of short peptide sequence consisting of 5~30 natural or artificial amino acid residues, which has the ability to enhance cell uptake of antigens and promote crossing various biological barriers. Because of its efficient and unique transmembrane transport ability, CPP has become a research hotspot in the biomedical field in recent years. Phage display technology (PDT) is a molecular technology to display on the surface of phage by genetic modification of phage DNA, which contains genetic sequences that can connect phenotypes with genotypes. This technology allows different peptide libraries to be expressed on the surface of phage particles, and can select peptides that specifically bind to targets, and it has the advantages of simplicity, high efficiency and low cost.Therefore, it can be used to realize targeted therapy without damaging other normal cells, which lays a foundation for developing new carriers for targeted drug delivery and realizing targeted drug delivery. In this paper, the research progress of cell penetrating peptides and screening cell penetrating peptides by phage display technology is reviewed, which also provides more effective ideas and methods for the research and development of feed antibiotic substitutes, and further provides new strategies and research directions for the precise killing of intracellular pathogens.

Key words: cell-penetrating peptides, phage display technology, targeting, antimicrobial peptide
