Antimicrobial Peptides (AMPs)

Antimicrobial peptides (AMPs), also called host defense peptides (HDPs) are part of the innate immune response found among all classes of life. Antimicrobial peptides have been demonstrated to kill Gram negative and Gram positive bacteria, enveloped viruses, fungi and even transformed or cancerous cells. Unlike the majority of conventional antibiotics it appears as though antimicrobial peptides may also have the ability to enhance immunity by functioning as immunomodulators.

    Several peptides have an antibacterial effect - but they are broken down in the human body too quickly to exert this effect. Empa (Swiss Federal Laboratories for Materials Science and Technology) researchers have now succeeded in encasing peptides in a protective coat, which could prolong their life in the human body. This is an important breakthrough because peptides are considered to be a possible solution in the fight against antibiotic-resistant bacteria. They occur in many organisms and constitute natural weapons against bacteria in the body, being known as antimicrobial peptides.
