Can beta-defensins be taken as supplements?

No. Beta-defensins are endogenous peptides produced by your own epithelial cells. They are not available as supplements or therapeutic products. Research focuses on understanding their biology and using them as templates for new antimicrobial drugs.

What is the difference between alpha- and beta-defensins?

Alpha-defensins (HNP-1 through 4, HD-5, HD-6) are primarily produced by neutrophils and Paneth cells, while beta-defensins (HBD-1, 2, 3) are produced by epithelial cells. They differ in disulfide bond connectivity and tissue distribution but share broadly similar antimicrobial mechanisms.

Why are beta-defensins important in skin disease?

Beta-defensins are a major component of skin innate immunity. Psoriatic skin overexpresses HBD-2 and HBD-3, which may explain resistance to skin infections in psoriasis. Conversely, atopic dermatitis skin has reduced beta-defensin expression, contributing to increased susceptibility to S. aureus and herpes simplex virus infections.

What is the recommended dose range for Beta-Defensins?

The research dose range is N/A — endogenous antimicrobial peptides produced by epithelial cells, administered via Not applicable (endogenous peptides), N/A.
