We also examined the iNKT cell-associated chemokine CXCL16 by quantitative real-time PCR analysis in saline- and allergen-challenged mice and found that CXCL16 expression is induced in the esophagus of mice following the induction of experimental EoE (Supplementary Figure 2C). The gene discussed is CXCL16; the disease is eosinophilic esophagitis.
