Harnessing the microbiota for therapeutic purposes

Area of Science:

• Microbiome research
• Host-microbiome interactions
• Microbiome-targeted therapies

Background:

• The human microbiome significantly impacts host physiology in health and disease.
• Recent advances have shifted microbiome research from descriptive studies to mechanistic insights.
• Understanding host-microbiome interactions is crucial for therapeutic development.

Purpose of the Study:

• To review current microbiome-targeted interventions.
• To discuss the potential and challenges of fecal microbiota transplantation (FMT).
• To explore emerging microbiome-targeting strategies and their role in personalized medicine and transplantation outcomes.

Main Methods:

• Review of current literature on microbiome-targeted interventions.
• Analysis of evidence from human randomized clinical trials, particularly for FMT.
• Discussion of emerging techniques including microbiota-targeted diets, microbial molecules, bacteriophages, and strain abundance control.

Main Results:

• Fecal microbiota transplantation (FMT) has the best clinical trial evidence but lacks defined indications due to safety and efficacy uncertainties.
• Probiotics show variable results.
• Emerging techniques like targeted diets, microbial molecules, bacteriophages, and precise strain control show promise but require further investigation.
• Microbiome variability is key for personalized medicine.
• The microbiome impacts transplantation outcomes.

Conclusions:

• Microbiome-targeted interventions hold significant therapeutic potential.
• Further research is needed to optimize safety, efficacy, and application of various microbiome-targeting strategies.
• Personalized approaches integrating microbiome variability can advance preventive and therapeutic strategies, especially in transplantation.
