Opsonization is a process whereby opsonins, which are molecules like antibodies or complement proteins, tag pathogens or particles for phagocytosis. This tagging enhances the ability of phagocytic cells, such as macrophages and neutrophils, to recognize and engulf foreign substances. In toxicology, opsonization can influence how toxins or toxic particles are handled by the immune system, potentially affecting their toxicity and the overall immune response.
