Human antimicrobial peptides and proteins occupy an important niche in the current research on human host defense and innate immunity [1,2,3,4,5,6,279]. Except for antimicrobial protein lysozyme, which was found in 1922, most of short cationic peptides were discovered after 1980 ( Table 1 ).
Antimicrobial peptides play a central role in innate and adaptive immunity. A given stimulus by bacteria leads to the release of constitutively expressed AMPs in different cells (here: epidermis). AMPs are released by neutrophils and will activate and recruit macrophages, monocytes, dendritic cells, and T-cells.
bacteriocin, and many others) fungi ( e.g. peptaibols, plectasin, and many others) cnidaria ( e.g. hydramacin, aurelin) many from insects and arthropods ( e.g. cecropin, attacin, melittin, mastoparan, In addition to constitutively expressed antimicrobial proteins, production of various antimicrobial proteins in keratinocytes is induced by bacterial compounds as well as proinflammatory cytokines. The resulting local accumulation of antimicrobial proteins offers a fast and very efficient way to prevent microbes from establishing an infection. Antimicrobial Peptides (AMPs) are produced by a variety of human immune and non immune cells in health and disease.
g. AMSDb (Eukaryotic peptides) (Tossi and Sandri 2002), BAPDb (bacterial peptides), ANTIMIC (natural antimicrobial peptides) (Brahmachary et al 2004) and APPDb. Some antimicrobial peptides are resident in normal, healthy skin. The amount of a particular antimicrobial peptide varies with the level of protection required.
Lysozyme, the first reported human antimicrobial protein, was identified in 1922 from nasal mucus by Alexander Fleming. This observation was overshadowed when in 1928 Fleming discovered penicillin, and in the 1940s he, along with others, brought the therapeutic use of penicillin to fruition, for which he was awarded a share of the 1945 Nobel Prize for Medicine.
Humans express several families of antimicrobial peptides in myeloid cells and on various epithelial surfaces where they are poised to defend against pathogens. Recently, antimicrobial peptides from animals and plants have served as templates for the design of new therapeutic antibiotics.

Cathelicidins are a group of cationic antimicrobial peptides occurring in human and many other species. 1 About 30 different cathelicidins are currently known in mammalian species. Cathelicidins are part of the innate immune system and exert antimicrobial activity by permeating and disintegrating the membranes of pathogens. 2 In man, LL‐37 is the sole identified member of the cathelicidin

Antimicrobial peptides play a central role in innate and adaptive immunity. A given stimulus by bacteria leads to the release of constitutively expressed AMPs in different cells (here: epidermis). AMPs are released by neutrophils and will activate and recruit macrophages, monocytes, dendritic cells, and T-cells.
As listed in the Antimicrobial Peptide Database (APD) (Wang et al., 2016), over 2300 AMPs have been identified from animals. Above 130 AMPs have been tested in humans to date. They are Regulation of antimicrobial peptide expression in human gingival keratinocytes by interleukin-1α.
