Epithelial cells of EoE patients can also produce alarmins (TSLP, IL-25, and IL-33), RANTES (CCL5), a chemotactic factor for T cells, eosinophils, and basophils (Jyonouchi et al., 2013), and CXCL16 (Lexmond et al., 2014), a chemotactic factor for iNKT cells. This evidence concerns the gene IL33 and eosinophilic esophagitis.
