- Opsonins are proteins that enhance the process of phagocytosis by marking pathogens for recognition by immune cells. Some examples of opsonins include12:
- Antibodies (such as IgG and IgM)
- Complement factors
- Phosphatidylserine-binding opsonins
- Other opsonins

- Antibodies. Antibodies are a part of your immune system that fit onto specific parts of pathogens (antigens) like a lock and key. Immunoglobulin G (IgG) and immunoglobulin M (IgM) are antibodies that also work as opsonins.
my.clevelandclinic.org/health/body/opsonizationExamples 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.www.biologyonline.com/dictionary/opsonization - People also ask

Apr 26, 2024 · Opsonization is a process that coats cells or pathogens with proteins (opsonins) to help phagocytes find and eat them. Learn about opsonins, phagocytosis, examples and conditions that affect opsonization.
Opsonin - Wikipedia
Opsonins induce phagocytosis of targets by binding the targets (e.g. bacteria) and then also binding phagocytic receptors on phagocytes. Thus, opsonins act as bridging molecules between the target and the phagocyte, bringing them into contact, and then usually activating the phagocytic receptor to induce engulfment of the target by the phagocyte.
