The action of antimicrobial peptides (AMPs), ranging from direct killing of invading pathogens to immune response modulation and other complex biological responses, has stimulated research and clinical interest for more than two decades, but the area is still burgeoning due to emerging discoveries in the functions, roles, and regulation of AMPs, thus making the study of antimicrobial peptides a multi-disciplinary and rapidly evolving field. In Antimicrobial...
