The gut microbiome influences allergic diseases like asthma and food allergies. Understanding its role may help treat eosinophilic gastrointestinal diseases (EGIDs), such as eosinophilic esophagitis (EoE).
Area of Science:
- Immunology
- Microbiology
- Gastroenterology
Background:
- Allergic conditions are rising in Westernized nations.
- Gut microbiome dysbiosis is implicated in allergic disease development.
- Factors like genetics, environment, and diet impact gut microbiota and immune homeostasis.
Purpose of the Study:
- To review the role of the gut microbiome in atopic conditions.
- To explore the development of immune tolerance from molecular and clinical perspectives.
- To investigate the potential application of this knowledge to eosinophilic gastrointestinal diseases (EGIDs), particularly eosinophilic esophagitis (EoE).
Main Methods:
- Literature review of murine and human studies.
- Analysis of molecular and clinical data on immune tolerance.
- Examination of gut microbiome's role in atopic diseases.
Main Results:
- Studies confirm the microbiota's role in asthma, atopic dermatitis, and food allergies.
- The microbiome's function in EGIDs remains largely unknown.
- Current research focuses on understanding tolerance mechanisms.
Conclusions:
- The gut microbiome is crucial in allergic disease pathogenesis.
- Further research is needed to elucidate the microbiome's role in EGIDs.
- Knowledge of the microbiome may lead to novel strategies for EGID prevention and treatment.
