Alpha-defensins

Alpha-defensins are small protein molecules part of the immune system’s natural defenses. They are produced mainly by certain white blood cells in our intestines and other tissues. Their primary role is to attack and destroy bacteria, fungi, and some viruses by disrupting their cell membranes, preventing infections. Alpha-defensins act quickly at the site of infection, helping to control microbial growth and supporting the body’s ability to fight off illness. They are an essential part of our innate immunity, providing immediate defense without needing prior exposure or immune memory.
