Natural antimicrobial peptides represent a primordial mechanism of immunity in both vertebrate and nonvertebrate organisms. Among them, histatins belong to a family of human salivary metal-binding peptides displaying potent antibacterial, antifungal and wound-healing activities. These properties, along with the ability...
