Correcting an immune-response deficiency by creating E alpha gene transgenic mice
Nature
|July 4, 1985
Summary
Researchers introduced a cloned E-alpha gene into mice lacking their own E-alpha genes. This restored immune response capabilities, demonstrating successful gene function and tissue-specific expression, even when induced by gamma-interferon.
Area of Science:
- Immunology
- Molecular Biology
- Genetics
Background:
- Mice lacking endogenous E-alpha genes cannot mount an immune response.
- E-alpha gene expression is crucial for immune function.
Purpose of the Study:
- To investigate the functional restoration of immune response in mice with a cloned E-alpha gene.
- To assess the tissue-specific transcription and inducibility of the introduced E-alpha gene.
Main Methods:
- Introduction of a cloned E-alpha gene into mouse embryos.
- Analysis of gene transcription in resulting transgenic mice.
- Induction of gene transcription in macrophages using gamma-interferon.
Main Results:
- Accurate and tissue-specific transcription of the introduced E-alpha gene was observed.
- E-alpha gene transcription in macrophages was inducible by gamma-interferon.
- Transgenic mice regained the ability to mount an immune response to a synthetic polymer.
Conclusions:
- A cloned E-alpha gene can restore immune function in genetically deficient mice.
- The introduced gene exhibits correct tissue-specific expression and inducibility.
- This study highlights the potential of gene introduction for correcting immune deficiencies.
