Mouse models are crucial for studying gut microbiota and disease, but results require careful translation to humans due to key differences. This article compares human and mouse gut microbiomes and discusses model limitations.
Area of Science:
- Microbiome Research
- Translational Medicine
- Animal Models
Background:
- The human gut microbiota is linked to numerous diseases, including metabolic, autoimmune, and neurodevelopmental disorders.
- Mice are widely used as models to study host-microbiota interactions and disease causality.
Purpose of the Study:
- To compare the human and murine core gut microbiota.
- To discuss the limitations of mouse models in recapitulating human gut microbiota shifts associated with diseases.
- To explore alternative model systems for gut microbiota research.
Main Methods:
- Meta-analysis of available human and murine gut microbiome datasets.
- Comparative analysis of host-microbiota interactions.
- Review of external factors influencing mouse model validity.
Main Results:
- Identified intrinsic similarities and differences between human and murine gut microbiota.
- Highlighted potential pitfalls in translating mouse microbiome research to human health.
- Evaluated the influence of external factors on mouse model systems.
Conclusions:
- Mouse models offer controlled environments for studying gut microbiota but have limitations for direct human application.
- Understanding species-specific differences is crucial for accurate interpretation of microbiome research.
- Alternative and complementary model systems may be necessary for comprehensive gut microbiota research.
