What is the Origin of Microbial Metabolite Therapy?

The term combines 'microbial,' referring to the gut flora, with 'metabolite,' a biochemical term for the end products of metabolic processes. 'Therapy' denotes the intentional use of these compounds for clinical benefit. This approach is a sophisticated evolution of traditional probiotic and prebiotic strategies.

What is the Mechanism of Microbial Metabolite Therapy?

The mechanism is based on the direct interaction of microbial metabolites with host cell receptors and signaling pathways. For example, SCFAs like butyrate and propionate bind to G-protein coupled receptors (GPCRs) on colonocytes and immune cells, triggering anti-inflammatory and metabolic responses. These metabolites also act as signaling molecules in the gut-brain axis, influencing satiety and mood regulation, thereby directly linking gut health to systemic function.

Microbial Metabolite Therapy

Meaning

The clinical application of specific, biologically active compounds—metabolites—produced by the commensal gut microbiota to exert therapeutic effects on the host’s physiology. This therapy leverages molecules like short-chain fatty acids (SCFAs) and secondary bile acids to modulate immune function, hormone signaling, and neurological health. It represents a targeted, post-biotic approach to leveraging the benefits of the gut microbiome.
