抗菌肽（ antimicrobial peptides， AMPs）是自然界生物体内非常重要的防御体系，能够对抗细菌、真菌、病毒甚至肿瘤细胞。抗菌肽具有广谱抗菌活性，且不易产生耐药性，这使得抗菌肽成为应用前景非常广阔的抑菌剂。本文综述了抗菌肽的来源、功能及其作用机制，并对其应用前景进行展望。%Antimicrobial peptides ( AMPs) are critical component of the innate immune system of organisms, and have been demonstrated with the activity against a variety of microorganisms including bacteria, yeast, fungi, viruses and even tumor cells.Broad-spectrum activity and low propensity for resistance development make the AMPs as a kind of great potential for development of new anti-infective agents.In this paper, the origins, the action, the mechanism, the application prospects are reviewed.
