摘要

昆虫抗菌肽是昆虫体内经诱导而产生的一类小分子碱性多肽物质,是昆虫先天免疫的重要效应分子,它具有不易形成耐药性、广谱抗菌、分子质量小等特点,并且对病毒、细菌、真菌、癌细胞具有杀伤作用。目前,在半翅目、鞘翅目、双翅目、膜翅目和鳞翅目等昆虫中都分离到了具有不同抗菌活性的抗菌肽。本文就昆虫抗菌肽的特点和种类、免疫机制、作用机制以及提高昆虫抗菌肽稳定性的策略进行综述,以期对昆虫抗菌肽的进一步研究和应用具有指导作用。

Abstract

Insect antimicrobial peptides are a class of small alkaline polypeptide substances induced by insects, which are important effector molecules of insect innate immunity. It has the characteristics of resistance to drug resistance, broad-spectrum antibacterial, small molecularweight, etc. and has killing effect on viruses, Bacteria, fungi, cancer cells. At present, antibacterial peptides with different antibacterial activities have been isolated from insects such as Hemiptera, Coleoptera, Diptera, Hymenoptera and Lepidoptera. This article reviews the insect antimicrobial peptides including its characteristics, types, immune mechanism and action mechanism, and the strategies to improve the stability of insect antimicrobial peptides. It is expected to have a guiding role on the further research and application of insect antimicrobial peptides.
