Mining the Microbiome and Microbiota-Derived Molecules in Inflammatory Bowel Disease

Area of Science:

• Microbiology
• Gastroenterology
• Immunology

Background:

• The intestinal microbiota, a complex ecosystem, is vital for host homeostasis, immune function, and gut barrier integrity.
• Alterations in gut microbial composition are linked to diseases like inflammatory bowel disease (IBD), though causal relationships are often unclear.

Purpose of the Study:

• To review advances and challenges in microbiota-based functional studies and therapeutic discovery for IBD.
• To highlight strategies for discovering microbiota-derived bioactive molecules for health and disease.

Main Methods:

• Utilizing model systems like gnotobiotic mice, probiotic mono-colonization, and prebiotic supplementation.
• Defining species-level functions of the intestinal microbiota.

Main Results:

• Identification of numerous species-level functions and therapeutic candidates for IBD.
• Recognition of the need to unlock molecular mechanisms for microbiota-derived therapies.

Conclusions:

• Significant progress has been made in understanding gut microbiome functions and developing therapeutic candidates for IBD.
• Further research into molecular mechanisms and bioactive molecules is crucial for advancing microbiota-based therapies.
