Opsonization occurs in the immune system. The organ systems involved are dependent on what mechanism is used. The lymphatic system is responsible for the transport and filtration of lymph fluid, which contains antibodies and lymphocytes.

Which antibodies are involved in opsonization?

Opsonization, or enhanced attachment, refers to the antibody molecules IgG and IgE, the complement proteins C3b and C4b, and other opsonins attaching antigens to phagocytes. This results in a much more efficient phagocytosis.

What is an example of opsonization?

Examples of opsonins are antibody molecules such as the IgM that are capable of activating the complement system to increase the susceptibility of antigens to phagocytosis. Apart from phagocytosis, opsonization can also promote antibody-dependent cell-mediated cytotoxicity.
