| Abstract: | Insect defensin, a member of the family of small cationic antibiotic peptides, was found in the hemolymph of several orders. They contribute to natural and acquired immune against Gram-negative microorganisms, and they work with a novel mechanism without the help of antibody, complement system, and phagocyte. The molecular characteristics, gene and expression, biological effects, and mechanisms of insect defensins are completely reviewed, and also the recent advances in insect defensins are mentioned briefly. |
