Antimicrobial peptides (AMPs) are small proteins produced by various organisms, including humans, plants, and animals. They play a crucial role in the immune system by targeting and destroying harmful bacteria, viruses, and fungi. AMPs are part of the innate immune response and can act quickly to prevent infections. These peptides work by disrupting the membranes of pathogens, leading to their death. Due to their effectiveness and ability to combat antibiotic-resistant strains, AMPs are being researched for potential therapeutic applications in medicine. Their unique mechanisms make them a promising alternative to traditional antibiotics in treating infections.
