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 ?-defensins are distinguished from the ?-defensins by the pairing of their three disulfide bonds. To date, six human ?-defensins have been identified; BD-1, BD-2, BD-3, BD-4, BD-5 and BD-6.  ?-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 ?-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.  ?-defensins contain a six-cysteine motif that forms three intra-molecular disulfide bonds.
