To address which specific ILC2 cytokines drive basal-cell hyperplasia in EoE, we conducted a flow cytometry analysis of esophageal immune cells in EoE, focusing on ILC2s expressing type 2 cytokines such as Areg, IL-5, and IL-13 (Fig. 4A–D). This evidence concerns the gene IL13 and eosinophilic esophagitis.
