Engineering the gut microbiome holds promise for health, but requires a shift from trial-and-error to rational interventions. Understanding and diagnosing issues are key steps for successful microbiome engineering and improved health outcomes.
Area of Science:
- Microbiology
- Gastroenterology
- Biotechnology
Background:
- The gut microbiome significantly impacts human health throughout life.
- Numerous studies link microbiome composition and function to various health conditions.
- Current microbiome engineering lacks sufficient real-world successful applications.
Purpose of the Study:
- To propose a framework for advancing gut microbiome engineering.
- To transition microbiome engineering from a trial-and-error method to a rational medical intervention.
Main Methods:
- Accurate diagnosis of health issues targeted by microbiome intervention.
- Development of technologies for precise microbiome modification.
- Establishing a systematic workflow for microbiome engineering.
Main Results:
- A proposed framework for rational microbiome engineering.
- Emphasis on understanding and diagnosing the target health problems.
- Focus on developing enabling technologies for desired microbiome changes.
Conclusions:
- A structured approach is necessary for successful gut microbiome engineering.
- Accurate diagnosis and targeted technological development are crucial.
- This framework aims to enable rational medical interventions through microbiome engineering.
