interferon
LowTechnical/Scientific/Medical
Definition
Meaning
A naturally occurring protein produced by cells in response to viral infection, inhibiting viral replication.
Any of a group of glycoproteins with antiviral and immunomodulatory properties, produced by eukaryotic cells in response to various stimuli; also refers to pharmaceutical preparations of these proteins used in medical treatments.
Linguistics
Semantic Notes
The term is almost exclusively used in immunology, virology, and clinical medicine. It refers to a specific biological agent, not a general process.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or spelling. Standard medical terminology in both varieties.
Connotations
Purely technical with no divergent connotations.
Frequency
Equally low-frequency outside medical contexts in both regions.

- Our bodies make interferon when we get sick.
- Interferon therapy can have significant side effects, including flu-like symptoms.
- Some viruses have evolved mechanisms to block the host's interferon response.

Learning
Memory Aids
Mnemonic
Think: 'INTERFERE' + 'ON' viruses. Interferon interferes with viruses turning ON replication.
Conceptual Metaphor
BODY'S ALARM SYSTEM (A signalling protein that alerts and activates the immune defence).

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid translating as 'интерференция' (interference), which is a physics term. The correct equivalent is 'интерферон', a direct loanword.
Common Mistakes
- Misspelling as 'interfearon' or 'interferron'.
- Using it as a verb (e.g., 'The cells interferon').
- Confusing it with 'interleukin' (another cytokine).

FAQ
Frequently Asked Questions
No, it is not an antibiotic. Antibiotics target bacteria. Interferon is a cytokine that targets viruses and modulates the immune system.
No, interferons are prescription-only biologic drugs, typically administered by injection under medical supervision.
Yes, it is naturally produced by the body's cells. However, medicinal interferon is usually produced recombinantly in laboratories.
Common side effects include flu-like symptoms (fever, chills, fatigue), depression, and decreased blood cell counts.
