Defensins (alpha and beta) are cationic peptides with a broad spectrum of antimicrobial activity that comprise an important arm of the innate immune system. The α-defensins are distinguished from the β-defensins by the pairing of their three disulfide bonds. To date, six human β-defensins have been identified; BD-1, BD-2, BD-3, BD-4, BD-5 and BD-6. β-defensins are expressed on some leukocytes and at epithelial surfaces.  In addition to their direct antimicrobial activities, they can act as chemoattractants towards immature dendritic cells and memory T cells.  The β-defensin proteins are expressed as the C-terminal portion of precursors and are released by proteolytic cleavage of a signal sequence and in some cases, a propeptide sequence. β-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds.   BD-4 is expressed in testis, stomach, uterus, neutrophils, thyroid, lung and kidney.  In addition to its direct antimicrobial activities, BD-4 is chemoattractant towards human blood monocytes.  Recombinant human BD-4 is a 6.0 kDa protein containing 50 amino acid residues.
