Opsonins play a crucial role in the immune response by enhancing phagocytosis. They are molecules that bind to the surface of pathogens, such as bacteria or viruses, marking them for destruction by immune cells like macrophages and neutrophils. This binding process makes it easier for phagocytes to recognize, engulf, and ultimately eliminate these pathogens. Opsonins typically include antibodies and complement proteins, which provide a signal that attracts phagocytic cells to the site of infection and facilitates the uptake of pathogens.

While initiating inflammation and promoting clot formation are important functions within the immune and healing processes, they are distinct from the specific role of opsonins. Similarly, neutralizing toxins is a different mechanism of action relevant to other immune components, particularly antibodies, rather than phagocytosis enhancement directly. Thus, the primary function of opsonins is to facilitate the recognition and clearance of pathogens through enhanced phagocytosis.
