Abstract
Purpose of review: This review aims to provide an overview of the current understanding of eosinophilic gastrointestinal disorders (EGIDs) and the role of the epithelium in influencing disease pathogenesis to inform and devise future therapeutic strategies.
Recent findings: Changes in epithelial cell structure, functions, and integrity are observed in EGIDs. In eosinophilic esophagitis (EoE), the esophageal epithelium has been shown to play key roles in perpetuating the inflammatory response in EoE through the expression of pro-inflammatory cytokines and immunological cell-surface proteins. Similar mechanisms appear to exist in the other EGIDs, including eosinophilic gastritis (EoG), eosinophilic enteritis (EoN), and eosinophilic colitis (EoC). Because of the increasing rarity of each non-EoE EGID, research focusing on how the epithelium is modulating disease in each lower gastrointestinal compartment is still in its rudimentary stages.
Summary: While there has been significant progress in understanding the role of the epithelium in EoE, further research is needed to obtain a better understanding of the mechanisms mediating epithelial-immune crosstalk in non-EoE EGIDs. Using EoE-epithelial cell research to inform future EGID investigations could lead to the development of new therapeutic interventions, such as targeted therapies to restore epithelial barrier function and reduce inflammation, to improve rare disease-patient quality of life.
期刊介绍:
Current Opinion in Pediatrics is a reader-friendly resource which allows the reader to keep up-to-date with the most important advances in the pediatric field. Each issue of Current Opinion in Pediatrics contains three main sections delivering a diverse and comprehensive cover of all key issues related to pediatrics; including genetics, therapeutics and toxicology, adolescent medicine, neonatology and perinatology, and orthopedics. Unique to Current Opinion in Pediatrics is the office pediatrics section which appears in every issue and covers popular topics such as fever, immunization and ADHD. Current Opinion in Pediatrics is an indispensable journal for the busy clinician, researcher or student.
