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 ...
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 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.
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.
Dermcidin is a protein with 110 amino acids that in humans is encoded by the DCD gene. [3] [4] The full-length protein produces derived peptides as proteolysis-inducing factor (PIF) and other anti-microbial peptides, [4] secreted by human eccrine sweat glands onto the skin as a part of the innate host defense of the immune system.

[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.
