Motheater: an immunodeficient mouse with markedly less ability to survive that the nude mouse in a germfree
Journal of Immunology (Baltimore, Md. : 1950)
|May 1, 1976
Abstract:
The motheaten mouse is an immunodeficient mutant which has been found to have elevated immunoglobulin levels, to exhibit autoimmunity, and early death. Since survival is not improved by a germfree environment, it appears that some mechanism other than infection results in its early demise.
Insights
The motheaten mouse, an immunodeficient mutant, shows high immunoglobulin levels, autoimmunity, and early death. Its shortened lifespan is not due to infection, suggesting other underlying causes for this genetic condition.
Area of Science:
- Immunology
- Genetics
- Animal Models
Background:
- The motheaten mouse is a well-characterized immunodeficient mouse model.
- This mutant exhibits a complex phenotype including autoimmunity and premature death.
Purpose of the Study:
- To investigate the underlying mechanisms contributing to the early demise of motheaten mice.
- To differentiate between infectious and non-infectious causes of mortality in this model.
Main Methods:
- Phenotypic analysis of motheaten mice.
- Comparison of survival rates in conventional versus germfree environments.
Main Results:
- Motheaten mice display elevated immunoglobulin levels and signs of autoimmunity.
- Maintaining motheaten mice in a germfree environment did not improve their survival rates.
Conclusions:
- The early death observed in motheaten mice is not primarily caused by infections.
- Non-infectious mechanisms, potentially related to their immunodeficiency and autoimmunity, are responsible for the shortened lifespan.
