Because of the known increased expression of IFN-γ in Th1 diseases in children with EV71-associated BE, IFN-γ-induced protein-10 (CXCL10/IP-10), monokine induced by IFN-γ (CXCL9/MIG), and IFN-inducible T-cell α chemoattractant were studied. This evidence concerns the gene IFNG and Barrett esophagus.
