This is due to its ability to selectively reproduce in vitro the esophageal transcriptome characteristic of EoE in epithelial cell cultures [29], and induce the expression and secretion of the eosinophil-activating chemoattractants eotaxin-1/CCL11 and eotaxin-3/CCL26 [30], which then move eosinophils from blood to the esophageal tissues. The gene discussed is CCL11; the disease is eosinophilic esophagitis.
