Dermcidin vs Pyrrhocoricin

Dermcidin vs Pyrrhocoricin — mechanism, half-life, dosing, and research status compared. Which is right for your protocol?

Dermcidin
Antimicrobial Peptide

Dermcidin is a constitutively expressed antimicrobial peptide produced by eccrine sweat glands of human skin. It is secreted as a precursor and processed in sweat to yield active peptides that protect the skin surface from bacterial colonization....

Pyrrhocoricin
Antimicrobial Peptide

Pyrrhocoricin is a proline-rich antimicrobial peptide from the hemipteran insect Pyrrhocoris apterus (firebug). Unlike membrane-lytic AMPs, pyrrhocoricin exerts its effects by penetrating bacterial cells and interfering with intracellular targets, specifically the bacterial heat ...
