opsonization
Definition
- Noun:
- The process of making an invading microorganism more susceptible to phagocytosis: Opsonization is an immune system process where molecules called opsonins bind to the surface of pathogens, marking them for ingestion and destruction by phagocytic cells like macrophages and neutrophils.
Usage Examples
- Noun:
- The opsonization of bacteria is a critical step in the body's defense against infection.
- Antibodies facilitate opsonization by coating the pathogen.
- A deficiency in complement proteins can impair the opsonization process.
Advanced Usage
- "to enhance opsonization": to improve or increase the efficiency of the opsonization process.
- Certain vaccines are designed to enhance opsonization of the target pathogen.
- "mediated by opsonization": describing a process or effect that occurs because of opsonization.
- The clearance of the infection was mediated by opsonization and subsequent phagocytosis.
Variants and Related Words
- Opsonize (verb): To make a microorganism susceptible to phagocytosis.
- Antibodies help opsonize bacteria.
- Opsonin (noun): The molecule (e.g., antibody, complement protein) that carries out opsonization.
- IgG is a major opsonin in the immune response.
Synonyms
- Opsonisation (Alternative spelling, chiefly British English).
Related Phrases and Concepts
- Immune clearance: The broader process of removing pathogens, which often involves opsonization.
- Fc receptor binding: A key mechanism by which antibodies, after opsonizing a pathogen, interact with phagocytes.
- Complement activation: A pathway that produces proteins which act as opsonins.
Noun
-
process whereby opsonins make an invading microorganism more susceptible to phagocytosis
