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.

Amphibian antimicrobial peptides are a family of highly potent antimicrobial peptides with a large spectrum of activity, which are synthesized by vertebrates as an efficient host-defence mechanism against invading microorganisms.
In the first line of defense, inhaled bacteria are trapped by mucus and are swept toward the pharynx and are swallowed. [1] Bacteria which penetrate the mucous layer are dealt with a second line of defense which includes antimicrobial peptides that are secreted by the surface epithelium of the respiratory tract which kill many strains of ...
Arbitrium is a viral peptide produced by bacteriophages to communicate with each other and decide host cell fate. [1] It is six amino acids(aa) long, and so is also referred to as a hexapeptide. It is produced when a phage infects a bacterial host. and signals to other phages that the host has been infected.
