摘要抗菌肽是在多种生物体中表达的具有抗菌活性的肽类物质总称.皮肤频繁与环境中的微生物接触而不被感染,表皮抗菌肽起了重要作用.人类表皮抗菌肽主要包括防御素和cathelicidin家族的LL-37,由于其具有普通抗生素所不具有的一系列优点,使其生物学活性和与皮肤屏障的关系成为目前研究的热点,对其深入研究为抵御疾病、延缓衰老、相关皮肤病的发病机制及治疗等方面带来了新的希望.

abstractsAntimicrobial peptides refer to all of the peptides with antimicrobial activity expressed in various types of organisms.Skin-derived antimicrobial peptides play an important role in the protection of skin against infection by frequently contacting microbes in the environment.They mainly consist of defensins and cathelicidin LL-37.Since skin-derived antimicrobial peptides possess a series of advantages which are lacked by common antibiotics,their biological activity and correlation with skin barrier have become a hot spot in present studies.Further researches into skin-derived antimicrobial peptides will provide new hopes for thedefense against diseases,delay of aging,disclosure of pathogenesis of and development of treatment for somedermatoses.
