Animal models indicate that host defense peptides are crucial for both prevention and clearance of infection. It appears as though many peptides initially isolated as and termed "antimicrobial peptides" have been shown to have more significant alternative functions in vivo (e.g. hepcidin [18]). Dusquetide for example is an immunomodulator that ...
Defensins are integral components of the innate immune system and belong to the ancient superfamily of antimicrobial peptides (AMPs). AMPs are also known as host defense peptides (HDPs), [2] and they are thought to have diverged about 1.4 billion years ago before the evolution of prokaryotes and eukaryotes.
Defensin mimetics, also called host defense peptide (HDP) mimetics, are completely synthetic, non-peptide, small molecule structures that mimic defensins in structure and activity. [51] Similar molecules, such as brilacidin , are being developed as antibiotics , [ 52 ] anti-inflammatories for oral mucositis , [ 53 ] [ 54 ] and antifungals ...
Defensins are a family of microbicidal and cytotoxic peptides (antimicrobial peptides; AMP) that are involved in host defense, and help to maintain homeostasis of intestinal microbiota. DEFA5 is the main AMP that controls the enteric microbiota composition by selective killing of bacterial pathogens while preserving commensals.

A number of these defence peptides are secreted from the skin of frogs and other amphibians, including the opiate-like dermorphins and deltorphins, and antimicrobial dermaseptins, temporins, bombinins, magainin, pseudin, bombesins, and maculatins. [1] [2]
[6] [7] This then led to investigating small cationic peptides from nature, originally termed cationic antimicrobial peptides, [5] but eventually "host defence peptides". Hancock became one of the first and most prominent advocates that the major function of these peptides was as modulators of the immune system.
Protein S100-A7A (S100A7A), also known as koebnerisin, is a protein that in humans is encoded by the S100A7A (alias: S100A15) gene. [3]S100 proteins are a diverse calcium-binding family that regulate fundamental cellular and extracellular processes including cell proliferation and differentiation, cell migration, and the antimicrobial host defense as antimicrobial peptides.
