Antimicrobial Peptides (AMPs) are naturally occurring short proteins, typically 10–50 amino acids long, that serve as a critical component of the innate immune system in humans, animals, plants, and microorganisms. These peptides provide broad-spectrum protection against Gram-positive and Gram-negative bacteria, fungi, viruses, and parasites by disrupting microbial cell membranes and regulating immune responses. Their unique mechanism reduces the likelihood of resistance development compared to conventional antibiotics.
According to the World Health Organization (WHO), antimicrobial resistance (AMR) was associated with nearly 4.95 million deaths globally in 2019, including 1.27 million deaths directly caused by resistant bacterial infections. The Centers for Disease Control and Prevention (CDC) also reports more than 2.8 million antimicrobial-resistant infections and over 35,000 deaths annually in the United States.
Researchers have identified over 3,500 antimicrobial peptides across six kingdoms of life, with numerous candidates currently progressing through Phase I, II, and III clinical trials for treating wound infections, diabetic foot ulcers, respiratory infections, sepsis, and bloodstream infections.
In addition, approximately 1 in 31 hospitalized patients acquires a healthcare-associated infection daily, highlighting the growing need for innovative anti-infective therapies. Advances in peptide engineering, recombinant DNA technology, nanotechnology-based drug delivery, and artificial intelligence are improving peptide stability, bioavailability, and therapeutic performance.
Beyond human healthcare, antimicrobial peptides are increasingly used in veterinary medicine, agriculture, food preservation, aquaculture, and medical device coatings. Growing government support for AMR research and expanding clinical development pipelines continue to strengthen the future potential of antimicrobial peptides as next-generation therapeutics for combating drug-resistant infections worldwide.
