opsonisation
Học thuậtThân thiện
Definition
- Noun:
- The process by which opsonins make an invading microorganism more susceptible to phagocytosis: Opsonisation is a crucial immune response mechanism where molecules called opsonins coat the surface of a pathogen, marking it for ingestion and destruction by phagocytic cells like macrophages and neutrophils.
Examples of Usage
- Noun:
- The opsonisation of bacteria by antibodies is a key step in the body's defense.
- Researchers studied the efficiency of opsonisation in the patient's serum.
Advanced Usage
"Complement-mediated opsonisation": Opsonisation facilitated by proteins of the complement system, which can be activated independently of antibodies.
- Complement-mediated opsonisation provides an immediate, innate immune response.
"Antibody-dependent opsonisation": Opsonisation that specifically requires antibodies to bind to the pathogen surface, enhancing recognition.
- The vaccine aims to induce antibody-dependent opsonisation of the virus.
Variants and Related Words
Opsonization (n): The American English spelling of opsonisation.
- The terms opsonisation and opsonization are used interchangeably in immunology texts.
Opsonin (n): The substance (e.g., antibody, complement protein) that carries out the process of opsonisation.
- Immunoglobulin G is a major opsonin in the bloodstream.
Opsonize (v): The verb form meaning to carry out the process of opsonisation.
- Specific antibodies help opsonize the pathogen for phagocytes.
Synonyms
- Immune tagging: The general process of marking a pathogen for immune system recognition and destruction.
- Coating: Describes the physical action of opsonins covering the microorganism's surface.
