IgE Fc receptor expression of the human esophagus. a Dendritic cells of the esophagus express FcεRI. Anti-FcεRIalpha staining in esophageal tissue. Left: EoE, right non-inflamed control tissue. b Comparative expression analysis of CD23 and FcεRI in EoE tissue. c Esophageal dendritic cells (CD1a staining) and esophageal mast cells (C-kit staining). d FcεRI/CD1a immune fluorescence histochemistry of the esophagus.
