Animal models of eosinophilic esophagitis

Area of Science:

• Gastroenterology
• Immunology
• Pathology

Background:

• Eosinophilic esophagitis (EoE) is a chronic esophageal inflammatory condition.
• Significant progress in understanding EoE pathogenesis has been achieved over the last 25 years.
• Animal models have been crucial in advancing this understanding.

Purpose of the Study:

• To review the histopathological features of eosinophilic esophagitis (EoE) in animal models.
• To discuss the strengths and weaknesses of various animal models used in EoE research.
• To provide insights into the utility of these models for future studies.

Main Methods:

• Literature review of studies utilizing animal models for eosinophilic esophagitis.
• Analysis of histopathological findings in animal models that recapitulate EoE.
• Comparative assessment of the advantages and disadvantages of different animal models.

Main Results:

• Various animal models, predominantly in mice, exhibit key histopathological features of EoE.
• These models allow for the investigation of specific aspects of EoE pathogenesis.
• Each model possesses unique strengths and limitations impacting their applicability.

Conclusions:

• Animal models are indispensable tools for studying eosinophilic esophagitis (EoE).
• Understanding the specific characteristics and limitations of each model is vital for effective research.
• Continued development and refinement of animal models will further elucidate EoE pathogenesis and inform therapeutic strategies.
