What is the Origin of Butyrate Signaling Pathways?

Butyrate originates from the fermentation of dietary fiber by specific gut microbiota, hence its derivation from the microbial ecosystem. Signaling pathways describe the established routes through which this molecule exerts its physiological effects on host cells.

What is the Mechanism of Butyrate Signaling Pathways?

Butyrate primarily functions by inhibiting histone deacetylases (HDACs), thereby altering gene expression related to cell differentiation and inflammation. Additionally, it acts as a ligand for G-protein coupled receptors like GPR41 and GPR43 on enteroendocrine cells. Activation of these receptors modulates hormone release and influences systemic energy balance regulation.

Butyrate Signaling Pathways

Meaning

Refers to the molecular cascades initiated when the short-chain fatty acid butyrate interacts with cellular targets, particularly within the gut-brain axis and immune system. These pathways are crucial mediators of gut health and systemic metabolic signaling. Understanding these signals is vital for optimizing intestinal barrier integrity.
