2025 Virtual Microbiome Symposium

Gut Microbial Metabolites and Their Impact on Host Systems

On December 12, 2025, ISB hosted a virtual symposium on the influence of gut microbial metabolites on human physiology.

A Universe of Metabolites

The intestinal lumen represents a vast and underexplored ecosystem that harbors members of the gut microbiota and a universe of metabolites whose concentrations are dynamically regulated by both host and microbial activity. New classes of metabolites are continuously being unearthed, accompanied by detailed characterization of their effects on host physiology. In this symposium we heard from leading experts who presented their groundbreaking work on how specific microbial metabolites influence neural, immune, and endocrine systems.

ISB hosted this symposium on December 12, 2025. The intended audience was graduate students, postdocs, principal investigators, industry scientists, educators, clinicians, or any other variety of microbiome-curious person from across the globe.

In 2025 our sponsor Applied Microbiology International offered free memberships to anyone that registered and attended the event.
