β-Defensin-4 (human) (trifluoroacetate salt)

β-Defensin-4 is an antimicrobial peptide that protects epithelial surfaces and modulates immune responses. It exhibits chemotactic activity for monocytes and keratinocytes, stimulates cytokine production, and demonstrates bactericidal and fungicidal effects against pathogens like E. coli and C. albicans. Research applications include studying innate immunity, host defense mechanisms, and inflammatory skin conditions in both in vitro and in vivo models.
