Episode notes
Butyrate Is A Gut-Derived Immune Signal
- Butyrate is produced when gut bacteria ferment dietary fiber and fuels colon cells while acting as an immune-regulating signaling molecule.
- It inhibits histone deacetylases to increase anti-inflammatory gene expression and promote immune balance.
Molecular Anti-Inflammatory Mechanisms
- Butyrate inhibits histone deacetylases, shifting gene expression toward anti-inflammatory programs.
- It also suppresses NF-κB signaling, limiting cytokine cascades that drive chronic inflammation.
Immune Cell Reprogramming
- Butyrate shifts macrophages toward an anti-inflammatory, tissue-repair phenotype and strengthens the gut barrier.
- It promotes FOXP3-driven regulatory T cell development, expanding colonic Tregs for tolerance.
