originated in the study of insect immune mechanism, when the insects by external stimuli, the immune responses induced in the body to a substance with a strong antibacterial activity, antimicrobial peptides is one of the major constituent. Later, amphibians, mammals isolated similar antibacterial activity polypeptide people a new understanding of the origin of antimicrobial peptides and their role in the evolution. With the in-depth study of the structure and function of antimicrobial peptides, antimicrobial peptides - biofilm interaction mechanism, the molecular biology of antimicrobial peptide genes, antimicrobial peptide gene engineering, antimicrobial peptides showing broad application prospects in health care, agriculture and other fields. .
