• This mechanism of antibody-mediated increase in phagocytic efficacy is named opsonization. Opsonization involves the binding of an opsonin (e.g., antibody) to an epitope on a pathogen.

How does Opsonization of a pathogen occur?

• Opsonization of a pathogen can occur by antibodies or the complement system. Antibodies Antibodies are part of the adaptive immune system and are produced by plasma cells in response to a specific antigen. Different antigens stimulate different B cells to develop into plasma cells.

What is antibody opsonization and how does it work?

• Antibody opsonization is a process by which a pathogen is marked for destruction by antibody-dependent cellular cytotoxicity (ADCC), antibody-dependent cellular phagocytosis (ADCP), or complement-dependent cytotoxicity (CDC). 1) Antibodies (A) and pathogens (B) free roam in the blood.
