Environmental and Microbial Factors in Inflammatory Bowel Disease Model Establishment: A Review Partly through...

Area of Science:

• Gastroenterology and Immunology
• Microbiome Research
• Genetic Epidemiology

Background:

• Inflammatory bowel disease (IBD) is a multifactorial condition influenced by genetics, environment, and microbial interactions.
• Current IBD animal models often fail to capture the complex interplay of these factors.
• Mendelian randomization studies have provided new insights into IBD-associated environmental and genetic factors.

Purpose of the Study:

• To review the impact of environmental and microbial factors on IBD development and progression.
• To evaluate existing IBD animal modeling techniques and their limitations.
• To propose improved strategies for creating more relevant IBD experimental models.

Main Methods:

• Comprehensive literature review of IBD pathogenesis, environmental influences, and microbial interactions.
• Analysis of Mendelian randomization findings related to IBD.
• Comparative assessment of current animal models for IBD.

Main Results:

• Environmental and microbial factors significantly influence IBD pathogenesis and interact with the host immune system and microbiota.
• Few existing animal models effectively integrate both environmental and microbial components.
• Mendelian randomization data can guide the selection of relevant factors for model development.

Conclusions:

• Future IBD animal models must incorporate both environmental and microbial factors to accurately mimic human disease.
• Integrating these elements will enhance our understanding of IBD mechanisms at immune and genetic levels.
• This approach promises more reliable experimental models for IBD research and therapeutic development.
