Eomesodermin (Eomes) induces interferon-gamma (IFN-γ) production in cells lacking T-bet. Eomes binds the Ifng promoter and regulatory regions, influencing IFN-γ expression.
Area of Science:
- Immunology
- Molecular Biology
- Gene Regulation
Background:
- T-box transcription factors T-bet and eomesodermin (Eomes) regulate interferon-gamma (IFN-γ) expression.
- The specific role of Eomes in IFN-γ expression is not fully understood.
Purpose of the Study:
- Investigate the Eomes-dependent regulation of IFN-γ expression.
- Determine how Eomes interacts with the Ifng locus.
Main Methods:
- Ectopic expression of Eomes in T-bet/Eomes-negative mouse cell lines (BW5147, EL4).
- Luciferase reporter assays using the Ifng promoter.
- Chromatin immunoprecipitation (ChIP) assays.
- Analysis of histone modifications.
Main Results:
- Ectopic Eomes expression induced IFN-γ production in response to PMA/IM stimulation.
- Eomes bound to the Ifng promoter and conserved noncoding sequences (CNSs).
- Eomes increased permissive histone modifications at the Ifng locus.
- Stimulation enhanced Eomes binding to specific CNSs.
Conclusions:
- Eomes directly regulates IFN-γ expression by binding to the Ifng promoter and CNSs.
- Eomes binding is both constitutive and inducible, modulated by cellular stimulation.
- Eomes plays a significant role in controlling IFN-γ production.
