nude mouse
Very LowTechnical/Scientific
Definition
Meaning
A special laboratory mouse with a severe combined immune deficiency, lacking hair, and having no functional thymus.
A specific type of immunodeficient research animal (Mus musculus) used extensively in biomedical science, particularly in oncology and immunology, for accepting human tissue grafts or tumors without rejection.
Linguistics
Semantic Notes
This is a compound noun referring to a specific genetic strain of mouse. It is not used literally to describe a mouse without clothes. The name derives from its visibly hairless ('nude') phenotype. It is a proper noun for a specific model organism.
Dialectal Variation
British vs American Usage
Differences
No significant differences in meaning or usage between British and American English. The term is used identically in global scientific literature.
Connotations
Exclusively scientific and technical. No everyday or figurative connotations.

Learning
Memory Aids
Mnemonic
Imagine a tiny, hairless (nude) mouse in a lab coat, holding a test tube, to link the 'nude' (hairless/immune-deficient) state with its scientific purpose.
Conceptual Metaphor
THE BODY IS A LABORATORY (the mouse's body is a vessel for testing foreign biological material).
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not translate as 'голая мышь' in non-scientific contexts, as it will sound absurd and non-technical. In scientific texts, 'бестимусная мышь', 'нуда мышь', or 'мышь линии nude' are used.
- The word 'nude' is a fixed part of the strain name, not a descriptive adjective to be translated flexibly.
Common Mistakes
- Using it as a general term for any hairless animal.
- Interpreting it literally in a scientific text.
- Capitalizing it inconsistently (often not capitalized).

FAQ
Frequently Asked Questions
No. The hairlessness is a visible side effect of the genetic mutation, but the critical feature is the lack of a thymus gland, which causes severe immune deficiency.
While hairless pet mice exist, the term 'nude mouse' specifically refers to a laboratory-bred strain with a defined genetic makeup for research. They require extremely sterile conditions to survive and are not suitable as pets.
The name originates from the hairless (naked/nude) appearance of the mice due to the Foxn1 gene mutation. The official scientific designation is 'Foxn1nu'.
Their primary use is in xenograft research—implanting tissues or tumors from other species (especially human cancers) to study disease progression and test therapies without interference from the mouse's immune system.
