Systemic Analysis of Patient Derived Esophageal Epithelial Organoid Model Reveals Cell State Heterogeneity and Conservation of Differentiation Hierarchy

Alyssa Baccarella, Yusen Zhou, Tatiana A. Karakasheva…·Melanie A. Ruffner

The paper uses scRNA-seq to compare IL-13-treated esophageal organoids with EoE biopsies, revealing shared cell state heterogeneity and differentiation hierarchy dysregulation.

Proton pump inhibitors modulate esophageal epithelial barrier function and crosstalk with eosinophils

Ravi Gautam, Megha Lal, Margaret C. Carroll…·Melanie A. Ruffner

This study shows that omeprazole modulates esophageal epithelial barrier function and reduces eosinophil activation in an IL-13-induced model of eosinophilic esophagitis.
