title: Applications of antimicrobial peptides from fish and perspectives for the future.
abstract: Fish are a major component of the aquatic fauna. Like other organisms, fish secrete different kinds of antimicrobial peptides (AMPs), which are positively charged short amino-acid-chain molecules involved in host defense mechanisms. Environmental hazards and the greenhouse effect have led to increased evolution of drug- and vaccine-resistant pathogenic strains, and it is necessary to find new drugs with structural uniqueness to fight them. Aquatic sources contain thousands of fish species, and each secretes AMPs with structural differences which can be used by the pharmaceutical industry in its search for novel drugs to treat drug-resistant pathogens. Not only limited to antimicrobial functions, AMPs possess other desirable characteristics which may be exploited in the near future. In this review, we list fish AMPs available from published reports, and discuss application-oriented functions of these AMPs. Notably, the possibilities of using fish AMPs as antimicrobial agents, vaccine adjuvants, inactivated vaccines, and antitumor agents are discussed in this review.
