The number of natural compounds with antimicrobial activities is extensive but largely includes three functional groups: (1) diges-tive enzymes destroying microbial structures (e.g., lysozyme), (2)peptides that are able to bind essential elements such as zinc or iron (e.g., calprotectin and lactoferrin, respectively), and (3) pep-tides that penetrate the microbial membrane (e.g., defensins and cathelicidins, as discussed below) (Yacoby and Benhar 2007; Deans et al. 2005; Ohlsen et al. 2008; Hancock 2001; Steinstraesser et al.2004). Lysozyme as the first peptide with antimicrobial activity was identified by Alexander Fleming at the end of the 1920s. It is only in the past two decades, with the evolution in molecular biology tech-niques, that have allowed isolation and identification of individual peptides, and the establishment of their structural and functional features. To present, more than 1220 HDPs are known, including over 940 HDPs in eurkaryotic organisms, listed in three databases(Brahmachary et al. 2004; Fjell et al. 2007; Wang et al. 2009). ?? ?This aim of this review is to provide an overview of the current understanding of HDPs, with special emphasis on defensins and cathelicidins and their role in immunological defense in humanDefensins and cathelicidins are well studied and their potential both as natural antimicrobial compounds and as templates in development of novel synthetic antibiotics and immunoregulatory drugs is discussed.
