Cationic Peptides

Cationic peptides are small proteins that carry a positive electrical charge. They are part of the immune system and help fight infections by interacting with and destroying bacteria, viruses, and fungi, which often have negatively charged surfaces. These peptides can also modulate immune responses and promote healing. Due to their ability to target microbes selectively, cationic peptides are being explored as alternative antibiotics, especially against resistant strains. Their positive charge allows them to attach to microbial membranes effectively, disrupting their structure and causing cell death, making them important components in innate immunity and potential therapeutic agents.
