Antimicrobial peptides are a common mechanism of host defense utilized by a variety of species, from insects to humans.
Defensins are a large family of broad-spectrum antimicrobial peptides, identified originally in leukocytes of rabbits and humans.
Defensins, cationic/polar peptides (30-35aa; 3-4kD), are distinguished by a conserved tri-disulfides and a largely beta-Sheet structure.
Defensins, expressed at the cell surface, have been hypothesized to function as a biochemical barrier against microbial infection by inhibiting colonization of the epithelium by wide range of pathogenic microorganisms.
The genes encoding human alpha and beta defensins are clustered in a contiguous segment of chromosome 8p23.
Defensins are classified into two families designated and based on distinctive although similar, tri-disulfide linkages in the peptides.
beta-defensins are slightly larger and differ in the position and arrangement of 3 disulfides.
In humans, six defensin (cryptidins), HD 1-6 (HD1-4 are also known as HNP1-4 for Human Neutrophil Peptides), and two defensins, HBD-1 and HBD-2, have been identified to date.
Rat RBD-1 and RBD-2) and mouse (MBD1-4) homologues of the human beta-defensin have also been identified.
alpha-defensins are encoded by genes designated DEFA1-6, whereas human bdefensins are encoded by the DEFB1 and DEFb2 genes.
