What is Dermcidin secreted by?

sweat glands
Dermcidin: a novel human antibiotic peptide secreted by sweat glands.

Is Dermcidin a protein?

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

Where is Dermcidin found?

eccrine sweat glands
In human skin, dermcidin is expressed in the dark mucous cells of the secretory coil of eccrine sweat glands and is found in the Golgi complex and the secretory granules typical for a secreted protein [3,4].

What do antimicrobial peptides do?

Antimicrobial peptides inhibit cell division by inhibiting DNA replication and DNA damage response (SOS response), blocking the cell cycle or causing the failure of chromosome separation (Lutkenhaus, 1990).

How do Cathelicidins work?

Mechanism of antimicrobial activity Cathelicidins rapidly destroy the lipoprotein membranes of microbes enveloped in phagosomes after fusion with lysosomes in macrophages. Therefore, LL-37 can inhibit the formation of bacterial biofilms.

How do Bacteriocins work?

Bacteriocins are proteins or peptides synthesized by the ribosomal. When released by bacteriocin-producing bacteria, it can become combined with the corresponding receptor on the surface of the sensitive bacteria to kill the bacteria.

Where are Cathelicidins stored?

Cathelicidins are a group of antimicrobial peptides, varying in amino acid (a.a) sequence, structure and size. They are stored in the secretory granules of neutrophils and macrophages and can be released extracellularly upon leukocyte activation.

How do you increase Cathelicidin?

Supplementation with vitamin D increases cathelicidin expression in the lesions of atopic dermatitis patients and increases activated macrophage production of cathelicidin. The therapeutic potential of vitamin D and synthetic analogs against infection remain unexplored.

Who will benefit from antimicrobial peptides?

Antimicrobial peptides (AMPs) are the indispensable components of the innate immune system in various species including human, animals and plants and become the first-line defense against foreign attacks [3,8].
