Defensin beta 3 (BD-3) is a cationic non-haemolytic antimicrobial peptide and member of the beta-defensin family, highly expressed by skin and tonsils, which plays an important role in the innate immune response to potentially pathogenic microbes, including multiresistant S. aureus and vancomycin-resistant E. faecium.
