Definition of opsonin in English:

opsonin

noun ˈɒpsənɪnˈäpsənən

Biochemistry

An antibody or other substance which binds to foreign microorganisms or cells making them more susceptible to phagocytosis.
〔生化〕调理素
Example sentencesExamples
- A mixture of opsonins adhere to the bacterium and facilitate ingestion by alveolar macrophages.
- Note that an opsonin is a blood serum protein or fragment which when deposited on the surface of a bacteria, virus, immune complex, or other particulate material acts a signal for phagocytosis to cells bearing the appropriate receptors.
- Complement molecules can function as opsonins in the recognition of bacterial pathogens and in their elimination by phagocytosis of the bound complexes.
- In all infants, the spleen provides important protection against invading bacteria; it is also a source of opsonins and fixed-tissue macrophages, as well as antibody production.
- By some unknown process, Acupuncture raises levels of triglycerides, specific hormones, prostaglandins, white blood counts, gamma globulins, opsonins, and overall anti-body levels.

Derivatives

opsonic

adjective ɒpˈsɒnɪk

Biochemistry

One pool of GAS surface proteins induced antibodies that were both opsonic and potentially protective.
Example sentencesExamples
- Moreover, Lancefield's studies in 1959 showed that type-specific opsonic antibodies can persist for 10-20 years after a GAS infection in humans.
- The data suggests that they contain a surface antigen that showed antibody responses which were both opsonic and potentially protective.
- Here we report on the opsonic potential of the resulting sera and the level of protection induced by this peptide in comparison to a pepsin extract of the M protein.
- How did opsonic antibodies enhance alveolar macrophage effectiveness?

Origin

Early 20th century: from Latin opsonare 'buy provisions' (from Greek opsōnein) + -in¹.
