Abstract: Defensin is cationic,endogenous and cysteine enriched antimicrobial peptide which is widely distributed in animals,plants and insects.It plays an important role in animal immune regulation and plant defense.This paper reviews the concept,type,structure and action mechanism of defensin,summarizes the research progress of in vivo tissue expression and in vitro expression of defensin in cattle,horse,sheep,pig,deer and camel,and prospects the future applications of defensin in biopharmaceutical industry and livestock feed production.
