抗菌肽的临床应用与内源性表达调控研究进展

Progress on Antimicrobial Peptides' Gene Endogenous Expression Regulation and Clinical Application

抗菌肽是具有抗菌活性的一类短肽,具有分子量低、热稳定、广谱的抗菌、抗病毒及抑制肿瘤的生物活性,是动植物防御体系的一个重要组成部分,在机体抵抗病原的入侵方面起着重要的作用。但实践表明,作为抗生素替代品的抗菌肽的开发并非易事。针对近年来抗菌肽研究的热点,对抗菌肽的临床应用和表达调控进行了简要综述。

Antimicrobial peptides are a group of small molecular proteins with antibacterial activities, which are key components of animal and vegetation defense system and play an important role in protecting body from invasion of pathogens. These peptides have many characters such as low molecular weight, thermostability. And they have the wide range of antibacterial, antiviral spectrum and inhibiting growth of tumor cells. However, the development of antimicmbial peptides as antibiotic substitutes is far from easy. The recent warm spots about antimicrobial peptides, especially gene expression regulation and clinical application were reviewed.
