interleukin 3
Very LowTechnical/Scientific (Exclusively used in specialized fields like immunology, hematology, oncology, and biomedical research)
Definition
Meaning
A protein (cytokine) produced by white blood cells that stimulates the proliferation of blood stem cells and certain immune cells.
A specific hematopoietic growth factor, historically designated IL-3, which plays a key role in stimulating the production of various blood cells from the bone marrow, particularly during immune responses. It is often discussed in the context of cell signalling and immunology.
Linguistics
Semantic Notes
Term is part of a numbered interleukin family (IL-1, IL-2, etc.). Its primary semantic domain is cellular biology and medicine. It is a mass/uncountable noun referring to a substance. Often appears with its abbreviation 'IL-3'.

Examples
By CEFR Level

Memory Aids
Mnemonic
INTERLEUKIN 3: INTERnal LEUKocyte (white blood cell) messenger Number 3, which helps triple (3) the production of blood cells.
Conceptual Metaphor
A GROWTH FACTOR is a FERTILIZER/STIMULANT (for blood cell production). A CYTOKINE is a CHEMICAL MESSENGER or SIGNAL.

Common Pitfalls
Translation Traps (for Russian speakers)
- Avoid direct transliteration 'интерлекин 3' as a general vocabulary word; it remains a highly specialized term.
- Do not confuse with other interleukins (e.g., IL-2, IL-6) which have different functions.
- The number is part of the name, not a quantity.
Common Mistakes
- Using it as a countable noun (e.g., 'an interleukin 3').
- Confusing its function with other cytokines like erythropoietin or G-CSF.
- Pronouncing 'interleukin' with stress on the first syllable (correct is on the third: in-ter-LEU-kin).
