Strategizing the human microbiome for small molecules: Approaches and perspectives

Area of Science:

• Microbiology
• Metabolomics
• Genomics

Background:

• The human microbiome plays a vital role in health, with growing evidence linking it to various diseases.
• Mechanisms of human-microbe interactions remain largely undefined.
• The discovery of small molecules from the microbiome is nascent, despite its vast genomic potential.

Purpose of the Study:

• To review advances, approaches, and challenges in mining microbial scaffolds from the human microbiome.
• To highlight the importance of microbiome-derived small molecules for understanding host-microbe interactions.
• To discuss the potential of these molecules in guiding therapeutic interventions and modulating microbiome-based therapies.

Main Methods:

• Genomic platforms for analyzing microbial genetic potential.
• Microbe cultivation techniques for isolating and studying specific bacteria.
• Chemical analytic platforms for profiling microbiome-derived small molecules.

Main Results:

• The human microbiome possesses significant, yet largely untapped, potential for novel small-molecule biosynthesis.
• Current methods for small-molecule discovery from the microbiome face several challenges.
• Integrating genomic, cultivation, and chemical data is key to unlocking this potential.

Conclusions:

• Profiling microbiome small molecules and mechanistic studies are essential for understanding host-microbe interactions.
• Discovery of specific, therapeutically relevant microbial molecules could overcome limitations in current microbiota-modulating therapies.
• Further research into microbiome-derived molecules promises to advance human health and therapeutic strategies.
