Abstract

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
