opsoninlarla
Opsonins are proteins found in the blood that play a crucial role in the immune system's ability to recognize and eliminate pathogens. They are produced by the liver and are part of the complement system, a group of proteins that work together to enhance the immune response. Opsonins coat the surface of pathogens, such as bacteria and fungi, making them more susceptible to phagocytosis, a process where immune cells engulf and destroy the pathogens. This coating process is facilitated by antibodies, which are produced by the immune system in response to specific pathogens. The most well-known opsonin is the C3b fragment of the complement system, which binds to the surface of pathogens and marks them for destruction by phagocytic cells. Other opsonins include mannose-binding lectin (MBL) and properdin. Opsonins are essential for the effective functioning of the immune system, as they help to clear infections and maintain overall health.
