Translational research on the pathogenesis of eosinophilic esophagitis.

摘要

Eosinophilic esophagitis (EE) is an inflammatory disease of the esophagus characterized by eosinophilic infiltration of the esophageal epithelium. EE is a relatively new disease from clinical and research standpoints. A recent surge in basic and translational studies has emerged to understand its pathogenesis since its recognition as a separate entity from acid-induced gastroesophageal reflux disease in 1995. Our understanding of this disease is still limited, however. In this article, available evidence from translational studies on EE is discussed, focusing on the allergic nature of the disease and highlighting the role of various inflammatory cells found in the esophagus of patients who have EE. Esophageal remodeling in EE is also discussed.
