The Gut Microbiome and Xenobiotics: Identifying Knowledge Gaps.

Area of Science:

• Microbiology
• Toxicology
• Biomedical Science

Background:

• The gut microbiome's role in human health and disease is increasingly recognized.
• Mechanistic insights into host-microbiome interactions are often limited.
• Alterations in the gut microbiome can affect drug efficacy and xenobiotic toxicity.

Purpose of the Study:

• To identify data gaps in understanding how gut microbiome alterations impact human health.
• To address challenges in determining the microbiome's role in drug efficacy and xenobiotic toxicity.
• To foster collaboration between academia, government, and industry.

Main Methods:

• A workshop convened experts from diverse sectors (academia, government, industry).
• Discussions focused on current microbiome science, metabolites, biomarkers, and model systems.
• Presentations and breakout sessions identified critical research needs.

Main Results:

• Two critical issues emerged: defining health-related microbial composition/function and establishing standards for models, methods, and analysis.
• The need for reproducible and comparable microbiome studies was highlighted.
• Key recommendations were formulated to advance research.

Conclusions:

• Further research is needed to understand host-microbiome interactions and xenobiotic exposure consequences.
• Developing standardized approaches is crucial for advancing microbiome research.
• Identifying biomarkers for microbiome-associated disease and toxicity is a priority.
