Defensin vs Dermaseptin

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

Defensin
Antimicrobial Peptide

Defensins are a superfamily of small, cysteine-rich cationic antimicrobial peptides that form a critical component of innate immunity across virtually all multicellular organisms. In humans, alpha-defensins (HNP-1 to -4 in neutrophils; HD-5, HD-6 in intestinal Paneth cells) and b...

Dermaseptin
Antimicrobial Peptide

Dermaseptins are a family of 28-34 amino acid antimicrobial peptides first isolated from the skin of South American Phyllomedusa frogs. They are among the most potent broad-spectrum AMPs known, with activity against bacteria, fungi, protozoa, and viruses....
