Abstract

The skin serves as a strong barrier protecting us from invading pathogens and harmful organisms. An important part of this barrier comes from antimicrobial peptides (AMPs), which are small peptides expressed abundantly in the skin. AMPs are produced in the deeper layers of the epidermis and transported to the stratum corneum, where they play a vital role in the first line of defense against potential pathogens. Numerous AMPs exist, and they have a broad antibiotic-like activity against bacteria, fungi and viruses. They also act as multifunctional effector molecules, linking innate and adaptive immune responses. AMPs play an essential part in maintaining an optimal and functional skin barrier - not only by direct killing of pathogens, but also by balancing immune responses and interfering in wound healing, cell differentiation, reepithelialization and their synergistic interplay with the skin microflora.
